如何使用 boost beast 为 websocket 握手添加自定义标头

Question

How to send custom headers in the first handshake that occurs in the WebSocket protocol with boost beast ?

I want to use custom header in my initial request "x-custome-id : xxxxx".

Answer 1

You will have to put the custum header somthing like this

You might want to change a few details here and there

ws_.async_handshake_ex(host, <endpoint>,
            [<somerequestname>](request_type& reqHead) {
                reqHead.insert(http::field::<sometype>,xxxxx);},
            bind(Some handler));

Note:

you will have theses details like host , endpoint ,etc

This is what you want to get right - reqHead.insert(http::field::<sometype>,xxxxx);} Explore the option suitable for you in http::field::<sometype> explore the enum class field : unsigned short for this.

I've found the candidate solution as https://github.com/boostorg/beast/issues/70 .
But, this occurs compiler error with boost 1.69.
This issue also fixed with the solution https://github.com/boostorg/beast/issues/1470 .
