How to parse a JSON error in retrofit?

The thing that is required to parse the JSON error is the response converter. And the response converter is available via our Retrofit object. At first, we’re getting the error converter from the ServiceGenerator.retrofit () instance by additionally passing our APIError class as the parameter to the responseBodyConverter method.

First thing is to add .addConverterFactory (GsonConverterFactory.create ()) when creating your Retrofit instance. For example, if you had a User java class (such as shown below) that corresponded to your json, then your retrofit api could return Call

You can use it like this. A better approach is to let Retrofit generate POJO for you from the json (using gson ). First thing is to add .addConverterFactory (GsonConverterFactory.create ()) when creating your Retrofit instance.

You can use it like this. The important part are that the response type should be ResponseBody and use response.body ()?.string () to get the raw string. A better approach is to let Retrofit generate POJO for you from the json (using gson ).

If you get more than just the response status code, you can use the additional data to set the user in the right context and provide more information about the current error situation. That’s what this post is about: how to apply simple error handling using Retrofit 2.

The responseConverter method will return the appropriate converter to parse the response body type. In our case, we’re expecting a JSON converter, because we’ve received JSON data. Further, we call converter.convert to parse the received response body data into an APIError object.

You are using toString () in GSON’s fromJson which is not a JSON content. Replace your toString () as string () which will give you the JSON body. Also make sure to use the string () method only once and save the response in a variable, because it will return empty string if you used it again. Is this answer outdated? Is this answer outdated?

The answer is that we just pass a List of model class and Retrofit convert JSON Array object to the corresponding Model class. Here is our JSON Array response get from the Server after calling a request API. Here is our description function of API Interface.

Typescript doesn’t have any different methods for JSON parsing. We can use the same JSON.parse method used with JavaScript. In this tutorial, I will show you how to use JSON.parse to parse JSON data in typescript with a couple of different examples.

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first. I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself.
