未正确设置Apache HTTPClient头
我正试图通过代理请求通过HTTPS获取。代理以400:Bad请求回答。我用wireshark嗅探了一下数据,发现没有设置标题。出于安全考虑,我用括号替换了一些值。有人能帮忙吗 这是我实施的一部分:未正确设置Apache HTTPClient头,apache,https,proxy,header,httpclient,Apache,Https,Proxy,Header,Httpclient,我正试图通过代理请求通过HTTPS获取。代理以400:Bad请求回答。我用wireshark嗅探了一下数据,发现没有设置标题。出于安全考虑,我用括号替换了一些值。有人能帮忙吗 这是我实施的一部分: String urlString = ctx.getUrl(); HttpHost target; CloseableHttpClient httpclient; HttpClientContext localContext; try { CredentialsProvider credsP

头名称:代理连接
标题值:关闭
标题名称:代理授权
标题值:基本
标题名称:用户代理
标题值:MyDevice
标题名称:接受
标题值:text/html
至少这是回应:
内容长度响应代码:0 400
通过Wireshark嗅探,我发现在发送CONNECT时,没有设置请求内部的头文件

谢谢Damian Nikodem,
但我找到了解决办法。
第一个请求总是在没有用户头的情况下发送。
我改变了两件事,代理授权有效:
请求=新的HttpGeturlString;
HttpResponse response=httpclient.executerequest 我假设您正在尝试与SCADA或生产管理系统通信。在我看来,您正在通过代理向目标服务器发送普通HTTP,同时尝试通过HTTPS进行连接 我无法在wireshark转储中看到响应,但它很可能包含类似以下内容的错误消息:
<!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>
另外,你应该多编辑一点你的图片,因为它显示了很多关于你雇主/客户的信息 @Thorgas,我不明白你为找到解决方案而难过。您的意思是您发现了如何在CONNECT with HttpClinet中添加额外的头?我对此也感到困惑 但我发现在android中使用HttpsUrlconnection并没有这种问题。 URLConnection URLConnection=url.openConnectionproxy
HttpsURLConnection httpsUrlConnection = (HttpsURLConnection) urlConnection;
httpsUrlConnection.setRequestMethod("GET");
httpsUrlConnection.setRequestProperty("HEADER1","HEADER1Content");
httpsUrlConnection.connect();
我太困了,无法给出正确的答案,但是对于这样的问题,我推荐一个叫做Charles internet proxy的工具,它是调试类似问题的完美工具,即使是跨https。我在使用外部工具方面非常有限,因为我的应用程序运行在嵌入式系统上。
HttpsURLConnection httpsUrlConnection = (HttpsURLConnection) urlConnection;
httpsUrlConnection.setRequestMethod("GET");
httpsUrlConnection.setRequestProperty("HEADER1","HEADER1Content");
httpsUrlConnection.connect();
