这是一个重定向响应，他告诉你去访问响应中location所指示的网址。
你把代码改一下，当饭后301响应的时候，改一下name的值重新走一下26行岛2行的过程就OK了（34行同样需要相应改成location中的域名）。
Qt http请求返回301与302_course
2017-03-31这样写的代码返回的是301错误，并且没有得到得到响应头的首部，strList得到的是空的，但是我用c的socket和发包工具得到的是302错误，请问重定向问题，该怎么弄？为什么会得到空的响应头的首部？
django➕dwebsocket➕nginx报错301怎么解决？_course

在AWS Application Load Balancer上使用Go时，WebSocket连接失败并显示301_course
2019-09-15<div class="post-text" itemprop="text"> <p>I'm trying to run a Go Server with WebSockets on an AWS Application Load Balancer but I am getting an <strong>'Error during WebSocket handshake: Unexpected response code: 301'</strong>. </p> <p>AWS says that The Application Load Balancers supports WebSockets via <strong>ws://</strong> protocols but I can not find any further documentation other than the following:</p> <p>Here's <a href="https://aws.amazon.com/blogs/aws/new-aws-application-load-balancer/" rel="nofollow noreferrer">aws load-balancer link</a></p> <blockquote> <p>The Application Load Balancer supports two additional protocols: WebSocket and HTTP/2.</p> <p>WebSocket allows you to set up long-standing TCP connections between your client and your server. This is a more efficient alternative to the old-school method which involved HTTP connections that were held open with a “heartbeat” for very long periods of time. WebSocket is great for mobile devices and can be used to deliver stock quotes, sports scores, and other dynamic data while minimizing power consumption. ALB provides native support for WebSocket via the ws:// and wss:// protocols.</p> </blockquote> <p>I can get JavaScript to connect to my Go server via WebSockets locally but when I deploy AWS it does not work. This is when the JavaScript displays a 301 error.</p> <p>The Application Load Balancer is listening on <strong>HTTP: 80</strong> and that traffic is being directed to <strong>HTTPS: 443</strong>. All of the Security Groups are pretty much similarly set up to allow traffic through. If I do a normal GET call to retrieve data from my server while deployed on AWS it works perfectly fine.</p> <p>Local call that works to connect to localhost</p> <pre><code><script> let socket = new WebSocket("ws://localhost:8080/websocket") console.log("Attempting Websocket Connection") socket.onopen = () => { console.log("Successfully Connected"); socket.send("Hi From the Client!") } socket.onclose = (event) => { console.log("Socket Closed Connection: ", event) } socket.onmessage = (msg) => { console.log(msg); } socket.onerror = (error) => { console.log("Socket Error: ", error) } </script> </code></pre> <p>Connect to remote server that does not work.</p> <pre><code><script> let socket = new WebSocket("ws://myexamplesite.com/websocket") console.log("Attempting Websocket Connection") socket.onopen = () => { console.log("Successfully Connected"); socket.send("Hi From the Client!") } socket.onclose = (event) => { console.log("Socket Closed Connection: ", event) } socket.onmessage = (msg) => { console.log(msg); } socket.onerror = (error) => { console.log("Socket Error: ", error) } </script> </code></pre> <p>nginx.conf </p> <pre><code>events { worker_connections 1024; } http { server_tokens off; server { listen 80; location / { proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $http_host; proxy_pass http://web:8080/; } } } </code></pre> <p>I expect to be able to establish a WebSocket connection but the following error is returning from the JavaScript file: </p> <p><em>WebSocket connection to 'ws://myexamplesite.com/websocket' failed: Error during WebSocket handshake: Unexpected response code: 301</em></p> </div>
