OkHttp在android中用于发出网络请求 [英] OkHttp in android for making network requests

问题描述

我想做什么 ::

我正在尝试学习 Okhttp 在Android中进行网络通话

I am trying to learn the usage of Okhttp for making networking calls in android

我做了什么 ::

• 我已阅读他们的文档 此处


• 我已下载并在项目中添加了JAR


• 我正在使用 here

• I have read their documentation here
• I have downloaded and added the JAR in the project
• I am using their sample code from here

MyCode ::

MainActivity.java

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.internal.http.Request;
import com.squareup.okhttp.internal.http.Response;
    public class MainActivity extends Activity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

             Request request = new Request.Builder()
                .url("https://raw.github.com/square/okhttp/master/README.md")
                .build();

            Response response = client.execute(request);

            Log.d("ANSWER", response.body().string());

        }

    }

---

我正面临的错误 ::

行响应响应=客户端。执行（请求）;
我收到错误：

In the line Response response = client.execute(request); I am getting error as :

客户端无法解析变量

client cannot resolved to a variable

如何解决这个问题！

public class MainActivity extends Activity {

    OkHttpClient client = new OkHttpClient();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         Request request = new Request.Builder()
            .url("https://raw.github.com/square/okhttp/master/README.md")
            .build();

        Response response = client.execute(request);

        Log.d("ANSWER", response.body().string());

    }

}

现在我是面临错误：

行中的

响应响应= client.execute（请求）; as 方法execute（Request）未定义类型OkHttpClient

推荐答案

方法执行（请求）未定义类型OkHttpClient

The method execute(Request) is undefined for the type OkHttpClient

您收到此异常是因为没有这样的方法，即执行（请求） OkHttpClient 。而是在调用对象上调用，该对象是使用 OkHttpClient 对象获得的，如下所示：

You are getting this exception because there is no such method ie.execute(Request) for OkHttpClient. Rather it is invoked on Call object which is obtained using OkHttpClient object as follows:

  Call call = client.newCall(request);
  Response response = call.execute();

我认为你应该使用

Response response = client.newCall(request).execute();

而不是响应响应= client.execute（请求）;
