Question

我开发了一种常见的post方法来将帖子请求发送到服务。

private final   String post(String path,String requestBody){
    String uriStr = "http://208.112.83.44:84/api"+path;
    String json = null;

     try {

         URL url = new URL(uriStr);

         HttpURLConnection conn =    (HttpURLConnection) url.openConnection(); 

            byte[]postData = requestBody.trim().getBytes(StandardCharsets.UTF_8);
            Integer postDataLength = postData.length;
            conn.setRequestMethod("POST");
            conn.setDoOutput(true);
            conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");
            conn.setRequestProperty("content-type", "application/json");
            conn.setRequestProperty("Authorization", "QkJDQzVCMkEtMEJBNS0055676UE5ODMtMjJEOUVGODQ2RjdC");
            conn.setRequestProperty("x-ApplicationId", "bbcc5b2a-99099-a983-22d9ef846f7b");
            conn.setRequestProperty("charset", "utf-8");
            conn.setFixedLengthStreamingMode(postDataLength);
            OutputStream wr = conn.getOutputStream(); 
            wr.write(postData);
            wr.flush();
            wr.close();
            InputStream input = conn.getInputStream();
            BufferedReader in = new BufferedReader(new InputStreamReader(input));
            String inputLine;
            StringBuffer response = new StringBuffer();
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            json = response.toString();
            in.close();


        } catch (IOException ex) {
            ex.printStackTrace();
        }
    return json;

}

我将post方法称为

this.post("/authentication","{"Email":"laskum@gmail.com","Password":"Lasa@123"}");

但是我得到了例外。

我提到了许多与相同异常相关的帖子，其中大多数都提到了将User Agent添加到请求的解决方案，因为我已添加如下

conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");

我仍然得到同样的例外。当我尝试通过浏览器成功发送请求并使用200状态代码响应时。

请帮我一个有任何想法的人。看看我的代码吧。

我对问题进行了排序。在调用post方法之前，需要使用端口启动代理。

所以我添加了以下内容。

WebServiceUtil.initSocksProxy("6789");

403通过Java应用程序调用服务时给出的响应，但不是通过浏览器调用时
