使用Android Studio OkHttpClient的方法？相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。
首先記住，使用網絡的時候一定要加入權限，加入到AndroidMainfest.xml中
<uses-permission android:name="android.permission.INTERNET" />
在初次使用的時候會出現報錯。cannot resolve symbol OkHttpClient
這里需要引入
implementation 'com.squareup.okhttp3:okhttp:3.0.1'
然后刷新下項目就可以了。
代碼：
package com.example.administrator.testclient;
import com.squareup.*;
import java.io.IOException;
import okhttp3.FormBody;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
public class BaseHttpClient {
public static final MediaType MEDIA_TYPE_MARKDOWN
= MediaType.parse("text/x-markdown; charset=utf-8");
// 01. 定義okhttp
private final OkHttpClient client = new OkHttpClient();
public BaseHttpClient(){
//client.connectTimeoutMillis();
}
/**
* 發送一個表單請求
* @throws Exception
*/
public void SendForm() throws Exception {
RequestBody formBody = new FormBody.Builder()
.add("search", "Jurassic Park")
.build();
Request request = new Request.Builder()
.url("https://en.wikipedia.org/w/index.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());
}
/**POST 請求
* 發送一個string請求
* @throws Exception
*/
public void SendPostString() throws Exception {
String postBody = ""
+ "Releases\n"
+ "--------\n"
+ "\n"
+ " * _1.0_ May 6, 2013\n"
+ " * _1.1_ June 15, 2013\n"
+ " * _1.2_ August 11, 2013\n";
Request request = new Request.Builder()
.url("https://api.github.com/markdown/raw")
.post(RequestBody.create(MEDIA_TYPE_MARKDOWN, postBody))
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful())
throw new IOException("Unexpected code " + response);
System.out.println(response.body().string());
}
/**POST 請求
* 發送一個From請求
* @throws Exception
*/
public void SendPostFrom() throws Exception {
RequestBody body = new FormBody.Builder()
.add("name", "sy")//添加參數體
.add("age", "18")
.build();
Request request = new Request.Builder()
.post(body) //請求參數
.url("http://123.207.70.54:8080/SpringMvc/hello")
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful())
throw new IOException("Unexpected code " + response);
}
/**Get請求
* 發送一個From請求
* @throws Exception
*/
public void SendGetFrom() throws Exception {
Request request = new Request.Builder()
.get() //請求參數
.url("http://123.207.70.54:8080/SpringMvc/hello")
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful())
throw new IOException("Unexpected code " + response);
}
}測試發現，上面的用不了，下面放一個測試通過的方法：
public void getDatasyncFactory(){
new Thread(new Runnable() {
@Override
public void run() {
try {
OkHttpClient client = new OkHttpClient();//創建OkHttpClient對象
Request request = new Request.Builder()
.url("http://123.207.70.54:8080/SpringMvc/hello")//請求接口。如果需要傳參拼接到接口后面。
.build();//創建Request 對象
Response response = null;
response = client.newCall(request).execute();//得到Response 對象
if (response.isSuccessful()) {
Log.d("kwwl","response.code()=="+response.code());
Log.d("kwwl","response.message()=="+response.message());
Log.d("kwwl","res=="+response.body());
//此時的代碼執行在子線程，修改UI的操作請使用handler跳轉到UI線程。
}
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
