Okhttp网络请求使用方法

Okhttp的Github：https://github.com/square/okhttp

导入依赖

implementation 'com.squareup.okhttp3:okhttp:3.5.0'

创建OkHttpClient

OkHttpClient okHttpClient = new OkHttpClient();
 

创建请求

  

   

    

     

    
    

     

      Request request = new Request.Builder()
     
    
   

    

     

    
    

     

       .get()
     
    
   

    

     

    
    

     

       .url("http://某服务器地址/HOME_URL.json")
     
    
   

    

     

    
    

     

       .build();
     
    
  
 

Call call = okHttpClient.newCall(request);
 

用enqueue这一个

  

   

    

     

    
    

     

       call.enqueue(new okhttp3.Callback() {
     
    
   

    

     

    
    

     
 @Override
     
    
   

    

     

    
    

     
 public void onFailure(okhttp3.Call call, IOException e) {
     
    
   

    

     

    
    

     

       Toast.makeText(getActivity(), "请检查网络连接", Toast.LENGTH_SHORT).show();
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     
 @Override
     
    
   

    

     

    
    

     
 public void onResponse(okhttp3.Call call, okhttp3.Response response) throws IOException {
     
    
   

    

     

    
    

     

       Start start = new Gson().fromJson(response.body().string(), Start.class);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     

       });
     
    
   

    

     

    
    

     

       }
     
    
  
 

基本用Okhttp请求就这些

看下具体的代码

  

   

    

     

    
    

     

      OkHttpClient okHttpClient = new OkHttpClient();
     
    
   

    

     

    
    

     

       Request request = new Request.Builder()
     
    
   

    

     

    
    

     

       .get()
     
    
   

    

     

    
    

     

       .url("http://某服务器地址/HOME_URL.json")
     
    
   

    

     

    
    

     

       .build();
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       okhttp3.Call call = okHttpClient.newCall(request);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       call.enqueue(new okhttp3.Callback() {
     
    
   

    

     

    
    

     
 @Override
     
    
   

    

     

    
    

     
 public void onFailure(okhttp3.Call call, IOException e) {
     
    
   

    

     

    
    

     

       Toast.makeText(getActivity(), "请检查网络连接", Toast.LENGTH_SHORT).show();
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     
 @Override
     
    
   

    

     

    
    

     
 public void onResponse(okhttp3.Call call, okhttp3.Response response) throws IOException {
     
    
   

    

     

    
    

     

       Start start = new Gson().fromJson(response.body().string(), Start.class);//这里是解析
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     

       });
     
    
   

    

     

    
    

     

       }
     
    
  
 

别忘了加上网络权限    <uses-permission android:name="android.permission.INTERNET"/>
