OkHttp的使用

一、OkHttp发起Get请求网络数据

直接上代码：

package com.canary.okhttptest;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import java.io.IOException;

import okhttp3.Call;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class MainActivity extends AppCompatActivity {

    private String jsonUrl = "http://192.168.1.168:8080/TestProject/JsonServlet";
    private String paramUrl = "http://192.168.1.168:8080/TestProject/ParamServlet";

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

        connect();
    }

    /**
     * 创建子线程，获取服务器返回数据
     */
    private void connect() {
        new Thread(){
            @Override
            public void run() {
                getData();
            }
        }.start();
    }

    /**
     * 通过get方式获取服务器返回数据
     */
    private void getData() {
        //创建网络请求对象
        OkHttpClient okHttpClient = new OkHttpClient();
        //创建请求参数
        Request request = new Request.Builder().url(jsonUrl).build();
        //创建发起网络请求对象
        Call call = okHttpClient.newCall(request);
        try {
            //发起网络请求
            Response response = call.execute();
            if(response.isSuccessful()){
                Log.d("网络连接成功","successful");
                Log.d("网络连接成功","服务器消息："+response.message());
                Log.d("网络连接成功","服务器消息："+response.toString());
                Log.d("网络连接成功","服务器消息："+response.body());
            }else {
                Log.d("网络连接失败","失败");

            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

二、OkHttp发起Post请求网络数据

代码：

package com.canary.okhttptest;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import java.io.IOException;

import okhttp3.Call;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class MainActivity extends AppCompatActivity {

    private String jsonUrl = "http://192.168.1.168:8080/TestProject/JsonServlet";
    private String paramUrl = "http://192.168.1.168:8080/TestProject/ParamServlet";

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

        connect();
    }

    /**
     * 创建子线程，获取服务器返回数据
     */
    private void connect() {
        new Thread(){
            @Override
            public void run() {
                postData();
            }
        }.start();
    }

    /**
     * 通过post方式获取服务器返回数据
     */
    private void postData() {
        //创建网络请求对象
        OkHttpClient okHttpClient = new OkHttpClient();
        //创建post数据
        MediaType type = MediaType.parse("application/json; charset=utf-8");
        String json = "{name:zmm,age:26}";
        RequestBody body = RequestBody.create(type,json);
        //创建请求参数
        Request request = new Request.Builder().url(jsonUrl).post(body).build();
        //创建发起网络请求对象
        Call call = okHttpClient.newCall(request);
        try {
            //发起网络请求
            Response response = call.execute();
            if(response.isSuccessful()){
                Log.d("网络连接成功","successful");
                Log.d("网络连接成功","服务器消息："+response.message());
                Log.d("网络连接成功","服务器消息："+response.toString());
                Log.d("网络连接成功","服务器消息："+response.body());
            }else {
                Log.d("网络连接失败","失败");

            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

三、OkHttp使用post参数向服务器传递数据

代码：

package com.canary.okhttptest;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.squareup.okhttp.Call;
import com.squareup.okhttp.FormEncodingBuilder;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.RequestBody;
import com.squareup.okhttp.Response;

import java.io.IOException;



public class MainActivity extends AppCompatActivity {

    private String jsonUrl = "http://192.168.1.168:8080/TestProject/JsonServlet";
    private String paramUrl = "http://192.168.1.168:8080/TestProject/ParamServlet";

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

        connect();
    }

    /**
     * 创建子线程，获取服务器返回数据
     */
    private void connect() {
        new Thread(){
            @Override
            public void run() {
                postParam();
            }
        }.start();
    }

    /**
     * 使用post请求向服务器发送数据
     */
    private void postParam() {
        //创建网络请求对象
        OkHttpClient okHttpClient = new OkHttpClient();

        RequestBody requestBody = new FormEncodingBuilder()
                .add("name", "zmm")
                .add("age", "26")
                .add("job", "android")
                .build();
        //创建请求参数
        Request request = new Request.Builder().url(paramUrl).post(requestBody).build();
        //创建发起网络请求对象
        Call call = okHttpClient.newCall(request);
        try {
            //发起网络请求
            Response response = call.execute();
            if(response.isSuccessful()){
                Log.d("网络连接成功","successful");
                Log.d("message",""+response.message());
                Log.d("toString",""+response.toString());
                Log.d("body",""+response.body());
            }else {
                Log.d("网络连接失败","失败");

            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
