Question

如何为HttpClient上的每个请求获取特定凭据？问题我现在有第二个线程似乎取代以前的第一个线程凭据。

以下是我的示例代码：

    class GetThread extends Thread {
    HttpClient httpClient;

    private String username,password;

    public GetThread(HttpClient httpClient,String username,String password) {
        this.httpClient = httpClient;
        this.username= username;
        this.password= password;
    }

    public void run() {

        Credentials defaultcreds = new UsernamePasswordCredentials(username, password);
        httpClient.getState().setCredentials(new AuthScope("dummyhost", 80, AuthScope.ANY_REALM), defaultcreds);
        HttpMethod method = new GetMethod("http://dummyhost/RSL/servlets/dv.data");

        method.setDoAuthentication(true);
        try {
            httpClient.executeMethod(method);

            byte[] responseBody = method.getResponseBody();
            System.out.println(Thread.currentThread().getName()+" "+username+" "+new String(responseBody));

        } catch (Exception e) {
            e.printStackTrace();
        } 
         finally {
             method.releaseConnection();
         }

    }
}

这就是我在主要课程中的内容：

    MultiThreadedHttpConnectionManager connectionManager = 
        new MultiThreadedHttpConnectionManager();

    HttpClient httpClient = new HttpClient(connectionManager);
    GetThread getThread[] = {new GetThread(httpClient, "rsbatch1", "test1234"),
            new GetThread(httpClient, "rsbatch12", "test1234")};

    for(int i=0;i<getThread.length;i++)
    {
        getThread[i].start();
    }

如果您希望每个线程拥有单独的凭据，那么您还需要为每个线程设置一个单独的客户端 - 每个客户端都有一组凭据。

将GetThread的构造函数更改为

public GetThread(HttpConnectionManager connectionManager,String username,String password) {
    this.httpClient = new HttpClient(connectionManager);
    this.username= username;
    this.password= password;
}

那应该做你需要的。

Apache HttpClient 3，多线程，每个请求都有不同的凭证？
