OkHttpTools

对Okhttp3和RestTemplate进行简单封装,对外提供了POST、GET、PATCH、PUT、DELETE、上传文件、下载文件、取消请求、Ws/Wss请求.

• 如果异步使用相关JSON解析器，请主动添加该包，默认不会添加，以免引起不必要的引
• 添加对spring的restTemplate支持,可自定义相关参数，参考文件:okhttp-tools-default.yml,对restTemplate的关系映射使用的是fastjson

如何添加

 <dependency>
   <groupId>com.github.doobo</groupId>
   <artifactId>okhttp-tools</artifactId>
   <version>1.3.1</version>
 </dependency>

在spring项目中使用

@RestController
public class IndexController {

   /**
    * 代理URL资源文件
    */
    @GetMapping
    public ResponseEntity<byte[]> proxyHttp(String url){
        return RestTemplateUtil.getByClass(url, byte[].class, null);
    }
}

@Test
public void testGet(){
    int a = 1;
    ResponseEntity<String> byClass = RestTemplateUtil.getByClass("https://baidu.com?a={a}", String.class, null, a);
    System.out.println(byClass.getBody());
}

@Test
public void testPost(){
    String byClass = RestTemplateUtil.post("https://baidu.com", "{}"
            , new ParameterizedTypeReference<String>(){}, null);
    System.out.println(byClass);
}

配置链接池

okhttp:
  tools:
    startConfig: true
    maxIdleConnections: 30
    keepAliveDuration: 300
    connectTimeout: 10
    readTimeout: 20
    writeTimeout: 10

OkHttp调用示例

//发送get请求
String result = OkHttpClientTools.getInstance()
                .get()
                .addHeader("auth","你好")
                .url("http://www.baidu.com")
                .addParam("a", "B")
                .execute().body().string();
//简单文件上传
String str = new OkHttpClientTools(client)
        .upload()
        .url("http://pic.sogou.com/pic/upload_pic.jsp")
        .addParam("type","utf-8;text/json")
        .addFile("files", new File("/Users/doobo/Downloads/myAirTicket.png"))
        .execute().body().string();
System.out.println(str);

//简单下载文件
OkHttpClientTools.getInstance()
    .download()
    .url("http://p4.so.qhmsg.com/t01decceaa40a9f9a19.jpg")
    .filePath("/Users/doobo/next.jpg")
    .tag(this)
    .enqueue(new DownloadResponseHandler() {
        @Override
        public void onStart(long totalBytes) {
            System.out.println("The File is Downing " + totalBytes);
        }
        @Override
        public void onFinish(File downloadFile) {
            System.out.println("File was Down!");
        }
        @Override
        public void onProgress(long currentBytes, long totalBytes) {
            System.out.println("doDownload onProgress:" + currentBytes + "/" + totalBytes);
        }
        @Override
        public void onFailure(String error_msg) {
            countDownLatch.countDown();
        }
    });

//302转发兼容
Response res = OkHttpClientTools.getInstance()
                .get()
                .url("https://5fu8.com/m/userCenter.do?agentId=1&vt=5")
                .addHeader("Cookie","cookiesid=ce3ee9471-27e3-4411-ae94-d89f93dc4ce9-56911233|a3e962802165daacb807c298023a502e")
                .execute();
while (res.priorResponse() != null){
    System.out.println(res.priorResponse().code());
    res = res.priorResponse();
}

//webscoket请求实例
WsBuilder builder = OkHttpClientTools.getInstance().ws()
                .url(wsUrl)
                .build();
WsResponseHandler wsResponseHandler = new WsResponseHandler() {
    @Override
    public void onOpen(WebSocket webSocket, Response response) {
        mWebSocket = builder.getWebSocket();
        //开启消息定时发送
        startTask();
    }
    public void onMessage(WebSocket webSocket, String text) {
        //打印一些内容
    }
    public void onMessage(WebSocket webSocket, ByteString bytes) {
    }
    public void onClosing(WebSocket webSocket, int code, String reason) {
    }
    public void onClosed(WebSocket webSocket, int code, String reason) {
    }
    public void onFailure(WebSocket webSocket, Throwable t, Response response) {
        //出现异常会进入此回调
    }
};
builder.enqueue(wsResponseHandler);
