How to pass multiple parameters to web API controller methods?

Web API provides the necessary action methods for HTTP GET, POST, PUT, and DELETE operations. You would typically pass a single object as a parameter to the PUT and POST action methods. Note that Web API does not support passing multiple POST parameters to Web API controller methods by default.

In this code, PostAsJsonAsync method serializes the object into JSON format and sends this JSON object in POST request. HttpClient has a built-in method “PostAsXmlAsync” to send XML in POST request. Also, we can use “PostAsync” for any other formatter.

“Pass” : “Fail”, MaterialNumber = modelToCreate, }; return Request.CreateResponse (System.Net.HttpStatusCode.OK, NewProjectLog); } This is my MVC 5 project where I am simply trying to call the above web api method.

Passing Multiple Complex .. Asp.Net Web API introduces a new powerful REST API which can be consume by a broad range of clients including browsers, mobiles, iphone and tablets. It is focused on resource based solutions and HTTP verbs. Asp.Net Web API has a limitation while sending data to a Web API controller.

Now, we can setup a named route link in view as below: In this tutorial we have learn about the Laravel Passing Multiple Parameters In Route to Controller and its application with practical example.

In this tutorial you will learn about the Laravel Passing Multiple Parameters In Route to Controller and its application with practical example. Today in this tutorial, we will learn to pass multiple parameters through named route to controller method.

As long as you are passing either a single complex type via a POST operation, or multiple simple types via query string or POST buffer, there’s no issue. But if you need to pass multiple parameters as was easily done with WCF REST or ASP.NET AJAX things are not so obvious. Web API has no issue allowing for single parameter like this:

This section is a continuation of the previous two sections where we created necessary infrastructure for the Web API and also implemented GET methods. Here, we will implement POST method in the Web API. The HTTP POST request is used to create a new record in the data source in the RESTful architecture.

We already created Web API with Post method in the Implement Post Method section shown below. In the above Web API, PostNewStudent method will handle HTTP POST request http://localhost:64189/api/student. It will insert new record in the database using Entity Framework and will return 200 OK response status.

ASP.NET MVC4 Web API application defines post method to save customer. Customer is passed in json format in POST request body. Customer parameter in post method contains null values for properties. How to fix this so that posted data will passed as customer object ?

1) Download the code in the Source folder and add it to your Web API project or any other project in the solution. 2) Use attribute [MultiPostParameters] on the action methods that need to support multiple POST parameters. [MultiPostParameters] public string DoSomething(CustomType param1, CustomType param2, string param3) { }

You can even click the box to have all default values transferred over to the value area. With this endpoint, you’d supply both a path parameter – the {id} value of the virtual machine – and a body parameter – the JSON payload representing all of the values you wish to change for this particular virtual machine.

The Logical operator between the keyword search fields must be “OR”. Example: in a CRM application you want a simple search form with one text field where user can enter a record id, person’s name, or a person’s email address, or a company name and use the same value to search across the ID, Name, Email and Company fields.

Search requests run in the context of the signed-in user, identified using an access token with delegated permissions. The Microsoft Search API provides a query method to search across your data in Microsoft Search, where you pass a searchRequest in the request body, defining the specifics of your search.

The searchRequest resource supports passing multiple types of entities at a time. However, currently the only supported combination is for SharePoint and OneDrive entityTypes: driveItem, drive, site, list, listItem . Any combinations involving message, event, SharePoint and OneDrive types , or externalItem are currently not supported.

I need to pass dataset to web API to store dataset in database. this is my c# client side code. Previously I pass person data like this ( commented line ). But in this time I have a Dataset. How can I pass dataset to web api using http POST?

As we know passing data and getting responses between two activities are the most common thing we do during the development phase for a long time ago. Currently, the only way to get responses back from the next activity is passing Intent and requestCode through startActivityForResult.

Sample code demonstrating Activity Result API on GitHub. The new Activity Result API offers an easier way to do a lot of common tasks especially requestPermission , takePicture and takePhoto so we don’t need to rely on any other third party library anymore.

[HttpPost] public MyResult Route (MyRequestTemplate routingRequestTemplate) {…} [HttpPost] public MyResult TSPRoute (MyOtherTemplate routingRequestTemplate) {…} The default template they give when you create a new one makes this pretty explicit, and I would say you should stick with this convention:

Multiple GET and POST methods in ASP.NET Core Web API In ASP.NET Core MVC and Web API are parts of the same unified framework. That is why an MVC controller and a Web API controller both inherit from Controller base class. Usually a Web API controller has maximum of five actions Get (), Get (id), Post (), Put (), and Delete ().

SignalR version 2 does not have a built-in server API for disconnecting clients. There are plans for adding this functionality in the future. In the current SignalR release, the simplest way to disconnect a client from the server is to implement a disconnect method on the client and call that method from the server.

If the client goes into reconnecting mode but can’t establish a transport connection within the disconnect timeout limit, the server terminates the SignalR connection. When that happens, the server executes the Hub’s OnDisconnected method and queues up a disconnect message to send to the client in case the client manages to connect later.

SignalR makes every attempt to raise connection lifetime events in a predictable manner according to this scheme, but there are many variations of network events and many ways in which underlying communications frameworks such as transport APIs handle them.

What do you mean by Parameter Binding in Web API? The Parameter Binding in ASP.NET Web API means how the Web API Framework binds the incoming HTTP request data to the parameters of an action method of a Web API controller. The ASP.NET Web API action methods can take one or more parameters of different types.

Closed 6 years ago. Basically I want to pass a image file with ajax on submitting a form and retrieve the image and send it by email as an attachment file: I can’t seem to find what’s the error in my code ! Here’s the AJAX call :

In the current version of Web API, the usage of multiple complex objects (like your Content and Config complex objects) within the Web API method signature is not allowed. I’m betting good money that config (your second parameter) is always coming back as NULL. This is because only one complex object can be parsed from the body for one request.

Closed 3 years ago. I need to design a RESTful query API, that returns a set of objects based on a few filters. The usual HTTP method for this is GET. The only problem is, it can have at least a dozen filters, and if we pass all of them as query parameters, the URL can get quite long (long enough to be blocked by some firewall).

Following REST principles, I would want to create a GET method for my API that make a search using some criteria and return the results to the client. The problem is that the criteria can have up to 14 parameters, one of them is a list of complex objects, so…

So, by default , Web API will get the id parameter from query string and student parameter from the request body. Following is a valid HTTP POST request in the fiddler for the above action method. Post action method cannot include multiple complex type parameters because at most one parameter is allowed to be read from the request body.

As you can see above Get action method includes id parameter of int type. So, Web API will try to extract the value of id from the query string of requested URL, convert it into int and assign it to id parameter of Get action method. For example, if an HTTP request is http://localhost/api/student?id=1 then value of id parameter will be 1.

I have a script that uses the file picker but I need to pass a specific parameter which is called userId and is kept as a global variable in the calling script. As the calls are asynchronous it seems I cannot access this parameter. Is there a way to access the parameter from the html file or pass this parameter to the html?

The class EmployeeControllerFakeData would just have some hard-coded data you want to test. Since you now registered the EmployeeControllerFakeData that is the one which will be injected into the constructor.

Group 1: The container tries to prevent ambiguity by disallowing constructor resolution by default. If a type has multiple public constructors an exception is thrown. Group 2: The container selects the constructor with the most parameters. If this constructor contains dependencies that cannot be resolved an exception is thrown.

When a new HomeController object is constructed by IOC resolver, it will take an object that implements IStudent interface provided by the IOC container (the one you registered) via its constructor. You can read more about Constructor Injection here. Thanks for contributing an answer to Stack Overflow!

APIs may not process the parameter correctly if it’s the wrong data type or wrong format. Listing the data type is usually a good idea with all parameter types but is especially true for request bodies, since these are typically formatted in JSON. These data types are the most common with REST APIs:

Parameters are options you can pass with the endpoint (such as specifying the response format or the amount returned) to influence the response. There are four types of parameters: header parameters, path parameters, query string parameters, and request body parameters.

There are various ways to encode three components into URL param key/values. One way to encode operators is the use of square brackets [] on the key name. For example, GET /items?price [gte]=10&price [lte]=100 would find all the items where the price is greater than or equal to 10, but less than or equal to 100.

RESTful is only an architectural style. There are many beginner api-guide for API design readily available such as this guide and this guide . However, we didn’t find many api-guide on more advanced filtering and pagination, which inspired us to publish this post. URL parameters is the easiest way to add basic filtering to REST APIs.

Simple to parse on server side. The URL parameter key contains both the field name and operator. Easy to GROUP BY (property name, operator) without looking at the URL parameter values. No need to escape special characters in the filter value when operator is taken as a literal filter term.

Inside this Action method, the SearchCustomers method is called with empty string value as parameter and a Generic List of CustomerModel class objects is returned to the View. Inside the SearchCustomers method, the value of the Name parameter is wrapped into a JSON object which is then serialized into a JSON string.

Inside the SearchCustomers method, the value of the Name parameter is wrapped into a JSON object which is then serialized into a JSON string. The URL of the Web API along with its Controller method and the serialized JSON string is passed to the UploadString method of the WebClient class.

If you are using ASP.NET Web API then you should just pass data: JSON.stringify (things). What I did when trying to send some data from several selected rows in DataTable to MVC action:

After that I was able to call the webservice with the following (removed the op-parameter again): Change the second ? to &. If you look at the page rendered by http:// [localhost]:31856/MySystem/MyAPI.asmx, it will show you how to call it as an HTTP GET.

You can pass the parameter (if requires) like the way you pass while calling one method from another . Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question.

When you add the @RequestParam to a method argument with the type Map or MultiValueMap and a parameter name is not specified, then the map will be populated by all query parameters that are provided by the caller.

The custom controller is associated with the page because of the controller attribute of the component. As with standard controllers and controller extensions, custom controller methods can be referenced with {! } notation in the associated page markup.

The following routes work for both with parameter and without parameter because parameter was optional. For getting that parameter value we modified an Index Action Method which now take ID as input parameter and Using Content to Display value on view. Now let’s run the application and check how it works.

This becomes a slippery slope. If config settings are hard-coded in templates (such as by a directive or controller argument attribute), you can no longer re-use that template for anything but that single use.

It’s usually a matter of scope. If you use an ng-repeat which creates child scopes for each iteration, you would want to pass the instance variable as a parameter. Otherwise you wouldn’t know what it is. Other than that, I would say it’s just a matter of preference and ease of writing. – Zack Argyle Sep 23 ’13 at 19:27

Rather than mapping explicit server side resources or ‘nouns’ RPC calls tend simply map a server side operation, passing in parameters and receiving a typed result where parameters and result values are marshaled over HTTP.

A parameter binding is how Web API creates a value for a parameter. Here is the default rule for parameter binding: Simple types are taken from the URI. Complex types are taken from the request body. Simple types include all of the .NET Framework primitive types, plus DateTime, Decimal, Guid, String, and TimeSpan.

Web API binds action method parameters either with URL’s query string or with request body depending on the parameter type.

When Web API calls a method on a controller, it must set values for the parameters, a process called binding. By default, Web API uses the following rules to bind parameters: If the parameter is a “simple” type, Web API tries to get the value from the URI.
