okhttp3的简单使用

1、添加依赖

compile 'com.squareup.okhttp3:okhttp:3.4.0-RC1'

MAVEN

<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>3.4.0-RC1</version>
</dependency>

GRADLE

compile 'com.squareup.okhttp3:okhttp:3.4.0-RC1'

2、get请求

<span style="font-size:18px;">package okhttp3.guide;

import java.io.IOException;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class GetExample {
OkHttpClient client = new OkHttpClient();

String run(String url) throws IOException {
Request request = new Request.Builder()
.url(url)
.build();

try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}

public static void main(String[] args) throws IOException {
GetExample example = new GetExample();
String response = example.run("https://raw.github.com/square/okhttp/master/README.md");
System.out.println(response);
}
}</span>3、post请求
<span style="font-size:18px;">package okhttp3.guide;

import java.io.IOException;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class PostExample {
public static final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");

OkHttpClient client = new OkHttpClient();

String post(String url, String json) throws IOException {
RequestBody body = RequestBody.create(JSON, json);
Request request = new Request.Builder()
.url(url)
.post(body)
.build();
try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}

String bowlingJson(String player1, String player2) {
return "{'winCondition':'HIGH_SCORE',"
+ "'name':'Bowling',"
+ "'round':4,"
+ "'lastSaved':1367702411696,"
+ "'dateStarted':1367702378785,"
+ "'players':["
+ "{'name':'" + player1 + "','history':[10,8,6,7,8],'color':-13388315,'total':39},"
+ "{'name':'" + player2 + "','history':[6,10,5,10,10],'color':-48060,'total':41}"
+ "]}";
}

public static void main(String[] args) throws IOException {
PostExample example = new PostExample();
String json = example.bowlingJson("Jesse", "Jake");
String response = example.post("http://www.roundsapp.com/post", json);
System.out.println(response);
}
}</span>
