Question

我尝试使用HttpsURLConnection命中我的服务器，得到响应代码401 - 需要进行身份验证。尝试以下方法：

            Authenticator.setDefault (new Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication ("myuser", "!mypassword".toCharArray());
                }
            });

获得响应代码400 - 错误请求。

根据一些stackoverflow研究，我也尝试使用：

        String authorizationString = "Basic " + Base64.encodeToString(("username" + ":" + "password").getBytes(), Base64.DEFAULT);
        conn.setRequestProperty("Authorization", authorizationString);

同样的问题，代码400.我也信任所有使用@Chrispix方法的主机： Trust Anchor not found for Android SSL Connection 不确定这是否会以某种方式干扰，但这是针对原型而且网站证书无效，所以我需要绕过检查。

使用这些属性设置连接，不确定是否有任何错误或缺失：

        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
        conn.setReadTimeout(10000 /* milliseconds */);
        conn.setConnectTimeout(15000 /* milliseconds */);
        conn.addRequestProperty("Content-Type", "application/json");
        conn.setRequestMethod("POST");
        conn.setDoInput(true);

谢谢！

如何使用HttpClient？

HttpClient httpClient= new DefaultHttpClient();
HttpGet httpGet= new HttpGet(yourUrl);
String authString = (yourUserName+":"+yourPassword);
httpGet.addHeader("Authorization", "Basic " + 
    Base64.encodeToString(authString.getBytes(),Base64.DEFAULT));
HttpResponse response = httpClient.execute(httpGet);

似乎你想通过目前的证书检查，这个相关的链接可能会帮助你

试试这种方式

public String sendHttpRequest(String params)
{       
    URL url;
    String result = new String();
    try 
    {
        url = new URL(AUTHENTICATION_SERVER_ADDRESS);
        HttpURLConnection connection;
        connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded;charset=UTF-8");
        PrintWriter out = new PrintWriter(connection.getOutputStream());

        out.println(params);
        out.close();

        BufferedReader in = new BufferedReader(
                new InputStreamReader(
                        connection.getInputStream()));
        String inputLine;

        while ((inputLine = in.readLine()) != null) {
            result = result.concat(inputLine);  

        }
        in.close();         
    } 
    catch (MalformedURLException e) {
        e.printStackTrace();
    } 
    catch (IOException e) {
        e.printStackTrace();
    }           

    if (result.length() == 0) {
        result = HTTP_REQUEST_FAILED;
    }

    return result;


}

params参数应该采用这种格式

      public String authenticateUser(String username, String password) 
      {
           String params = "username="+ URLEncoder.encode(username,"UTF-8") +
                           "&password="+ URLEncoder.encode(password,"UTF-8") +
                    "&";

          String result = socketOperator.sendHttpRequest(params);       

          return result;
       }

将此功能称为认证...

似乎我得到了正确的响应 - 我认为400意味着格式错误的请求，但检查错误流我发现请求很好，但参数错误。菜鸟错误！

验证器响应代码400
