Apache HTTPClient标头未正确设置

Question

i'm trying to request a GET via HTTPS trough a Proxy. 我试图通过HTTPS通过代理请求GET。 The Proxy answers with 400:Bad Request. 代理回答400：错误请求。 I sniffed the data with wireshark and i have seen, that the headers are not set. 我用wireshark嗅探了数据，并且看到没有设置标头。 Because of security, i replaced some Values with <> Brackets. 由于安全性，我用<> Brackets替换了一些值。 Can anybody help? 有人可以帮忙吗？

This is a part of my implementation: 这是我的实现的一部分：

String urlString = ctx.getUrl();
HttpHost target;
CloseableHttpClient httpclient;
HttpClientContext localContext;
try
{
     CredentialsProvider credsProvider = new BasicCredentialsProvider();
     int proxyport = Integer.parseInt(ctx.getProxyPort());

     credsProvider.setCredentials(
         new AuthScope(<MyProxyUrl>, <MyProxyPort>),
         new UsernamePasswordCredentials(<MyProxyUser>, <MyProxyPassword>));

     httpclient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();

     target = new HttpHost(urlString, 443, "https");
     HttpHost proxy = new HttpHost(<MyProxyUser>, <MyProxyPassword>);

     RequestConfig config = RequestConfig.custom().setProxy(proxy).build();
     request = new HttpGet("/");
     request.setURI(new URI(urlString));
     //this method sets different header
     HttpProperty.setHeaders(request, ctx);
     request.setConfig(config);

     HttpResponse response = httpclient.execute(target, request);

I have traced the headers in the request with and printed name/value with the output below: 我已经使用以下输出跟踪了请求中的标头并打印了名称/值：

     Header[] headers = request.getAllHeaders();

Header Name:Proxy-Connection 标头名称：Proxy-Connection

Header Value:close 标头值：关闭

Header Name:Proxy-Authorization 标题名称：代理授权

Header Value:Basic 标头值：基本

Header Name:User-Agent 标头名称：User-Agent

Header Value: MyDevice 标头值：MyDevice

Header Name:Accept 标题名称：接受

Header Value:text/html 标头值：text / html

At least this is the response: Content length responesCode: 0 400 至少这是响应：内容长度responesCode：0 400

From Wireshark sniffing i found, that the headers which are defintly inside the request are not set when sending CONNECT. 从Wireshark嗅探我发现，发送CONNECT时没有设置请求中明确的标头。

EDIT: Thank you Damian Nikodem, but i found the solution. 编辑：谢谢Damian Nikodem，但我找到了解决方案。 The first request is always sent without user headers. 第一个请求始终在没有用户标头的情况下发送。 I changed two things, and the proxy authorization works: request = new HttpGet(urlString); 我做了两件事，代理授权起作用了：request = new HttpGet（urlString）; HttpResponse response = httpclient.execute(request); HttpResponse response = httpclient.execute（request）;

I am assuming that you are attempting to communicate with a SCADA or production management system. 我假设您正在尝试与SCADA或生产管理系统进行通信。 From what I can see you are sending plain HTTP to your target server via the proxy, while trying to connect via HTTPS. 从我可以看到，您正在尝试通过HTTPS连接时，通过代理向目标服务器发送纯HTTP。

I couldn't see the response in your wireshark dump, but it most likely contains a error message that looks something like this: 我在wireshark转储中看不到响应，但它很可能包含一条看起来像这样的错误消息：

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html>
 <head>
  <title>400 Bad Request</title>
 </head>
 <body>
    <h1>Bad Request</h1>
    <p>Your browser sent a request that this server could not understand.<br />
       Reason: You're speaking plain HTTP to an SSL-enabled server port.<br />
       Instead use the HTTPS scheme to access this URL, please.<br />
       <blockquote>Hint: <a href="https://????/"><b>https://???/</b></a></blockquote>
    </p>
 </body>
</html>

@Thorgas, I don't understand what you sad about "found the solution". @Thorgas，我不明白你对“找到解决方案”感到难过。 Do you mean that you found out how to add extra headers in the CONNECT with HttpClinet? 您的意思是您发现如何在CONNECT with HttpClinet中添加额外的标头吗？ I'm also confusing about this. 我对此也感到困惑。

But i found out that using HttpsUrlconnection in android doesn't have this kind of problem. 但我发现在android中使用HttpsUrlconnection没有这种问题。 URLConnection urlConnection = url.openConnection(proxy); URLConnection urlConnection = url.openConnection（proxy）;

HttpsURLConnection httpsUrlConnection = (HttpsURLConnection) urlConnection;
httpsUrlConnection.setRequestMethod("GET");
httpsUrlConnection.setRequestProperty("HEADER1","HEADER1Content");
httpsUrlConnection.connect();
