如何为HttpClient的特定连接设置HttpHeader？

Question

The most suggested question doesn't have the answer.

I would like to set a specific header for the entire http connection which HttpClient establishes and maintains (keep-alive is set to true), that is,

each request I make should contain my custom header. Obviously,

_httpClient.DefaultRequestHeaders.Add("MyHeader", "MyValue");

is not an option, since it sets the header for the entire HttpClient , whereas I would like to have it only for the specific connection , which is created when I make my first call to a URL at a server.

That server then keeps the connection alive and expects me to have a MyHeader header for each subsequent request that I make while the connection is .

Answer 1

You can do something like this example. On each request you can clear all request headers from your HttpClient . After that add the request headers which will help you.

client.DefaultRequestHeaders.Clear();

Simply you will not instantiate your HttpClient, also set configuration for request.

Answer 2

第一次通话后，将其删除

_httpClient.DefaultRequestHeaders.Remove("keep-alive");
