[英]WebSocket closes under Internet Explorer - error code 1006
My WebSocket implementation works correctly in Chrome and Firefox. 我的WebSocket实现可在Chrome和Firefox中正常运行。
In IE11 I get this error: 在IE11中,我收到此错误:
Websocket Error: Network Error 12152, The server returned an invalid or unrecognized response
Websocket错误:网络错误12152,服务器返回了无效或无法识别的响应
I use js WebSocket class and reactPhp and https://github.com/ratchetphp/RFC6455 for backend. 我使用js WebSocket类和reactPhp和https://github.com/ratchetphp/RFC6455作为后端。
This is the request-response data under IE. 这是IE下的请求-响应数据。 It looks ok to me.
在我看来还可以。
I checked that Websocket returns code 1006
and empty reason. 我检查了Websocket是否返回代码
1006
和空原因。
How can I fix the IE11 error? 如何解决IE11错误?
The problem was that in response headers I should return only one protocol in Sec-WebSocket-Protocols. 问题在于,在响应标头中,我应该仅在Sec-WebSocket-Protocols中返回一个协议。
Why it doesn't work only under IE - because I split the protocols in backend by comma+space but IE return the protocols without space only with comma separator. 为什么它仅在IE下不起作用-因为我在后端用逗号+空格分割了协议,但是IE仅使用逗号分隔符返回了不带空格的协议。 The other browsers return the protocols with comma+space.
其他浏览器以逗号+空格返回协议。
For example the code right in backend it looks like that: 例如,后端的代码如下所示:
array_map('trim', explode(',', $this->headers['Sec-WebSocket-Protocol'])); array_map('trim',explode(',',$ this-> headers ['Sec-WebSocket-Protocol'])));
