使用okhttp發送數據而沒有異步任務

Question

我可以使用這種方式使用Okhttp將字符串上傳到服務器嗎？

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.register); 
    toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    usernam = (EditText) findViewById(R.id.username); 
    passw = (EditText) findViewById(R.id.password); 
    email = (EditText) findViewById(R.id.email); 

    name = usernam.getText().toString(); 
    pass = passw.getText().toString(); 
    emails = email.getText().toString(); 

} 


private final OkHttpClient client = new OkHttpClient(); 

public void run() throws Exception { 
    String json = ""; 

    JSONObject jsonObject = new JSONObject(); 
    jsonObject.accumulate("name",name); 
    jsonObject.accumulate("password",pass); 
    jsonObject.accumulate("email",emails); 

    json = jsonObject.toString(); 

    RequestBody formBody = new FormEncodingBuilder() 
      .add("result", json) 
      .build(); 
    Request request = new Request.Builder() 
      .url("https://justedhak.comlu.com/receiver.php") 
      .post(formBody) 
      .build(); 

    Response response = client.newCall(request).execute(); 
    if (!response.isSuccessful()) throw new IOException("Unexpected code " + response); 

    System.out.println(response.body().string()); 
}

如果您想使用沒有AsyncTask的OkHttp，可以參考以下示例代碼，希望這有助於您！

public class MainActivity extends AppCompatActivity { 
    private static final String LOG_TAG = "OkHttp"; 
    private TextView mTextView; 
    private Handler mHandler; 
    private String mMessage; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mTextView = (TextView) findViewById(R.id.textView); 
     mHandler = new Handler(Looper.getMainLooper()); 
     OkHttpClient client = new OkHttpClient(); 
     // GET request 
     Request request = new Request.Builder() 
       .url("http://...") 
       .build(); 
     client.newCall(request).enqueue(new Callback() { 
      @Override 
      public void onFailure(Request request, IOException e) { 
       mMessage = e.toString(); 
       Log.e(LOG_TAG, mMessage); // no need inside run() 
       mHandler.post(new Runnable() { 
        @Override 
        public void run() { 
         mTextView.setText(mMessage); // must be inside run() 
        } 
       }); 
      } 

      @Override 
      public void onResponse(Response response) throws IOException { 
       mMessage = response.toString(); 
       Log.i(LOG_TAG, mMessage); // no need inside run() 
       mHandler.post(new Runnable() { 
        @Override 
        public void run() { 
         mTextView.setText(mMessage); // must be inside run() 
        } 
       }); 
      } 
     }); 
    } 
}

網絡調用必須完成關閉的UI線程，所以沒有。

你也從來沒有打電話給你的run（）方法，在您的活動，所以它不會被執行

編輯：最大皮諾是在RXJava正確可以用來使這種調用很容易，但是，仍然會在不同的線程上執行呼叫
