在此处放置JSON响应，然后从此网站下载Java代码.然后，将此Java代码放入您的项目中并使用它.该网站将使用所有必填字段制作所有必填类，非常适合您的JSON响应.我已经使用了很多次，这肯定会起作用.

Put your JSON response here and download java code from this website . Then put this java code into your project and use it . This website will make all required classes with all required fields which will be perfect fit for your response of JSON. I have used it many time this will surely work.

http://square.github.io/retrofit/ here you can get detailed information about how to use retrofit to POST or GET data .

Retrofit将您的HTTP API转换为Java接口.

Retrofit turns your HTTP API into a Java interface.

public interface YourService {
  @GET("users/{user}/repos")
  Call<List<Repository>> listRepos(@Path("user") String user);
}

Retrofit类生成接口的实现.

The Retrofit class generates an implementation of the interface.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://api.yourAPI.com/")
    .build();

YourService  service = retrofit.create(YourService .class);

Call<List<Repository>> repos = service.listRepos("myrepository");

使用注释描述 HTTP 请求:

• URL参数替换和查询参数支持对象 转换为请求正文(例如JSON，协议缓冲区)多部分 请求正文和文件上传

• URL parameter replacement and query parameter support Object conversion to request body (e.g., JSON, protocol buffers) Multipart request body and file upload
