Settings for Golang net HTTP library-related timeouts

This is a creation in Article, where the information may have evolved or changed. timeout settings in the Net.http package
Service Side
app. Server.readtimeout app. Server.writetimeout
is the option set for all requests
The default Net.http keepalived is on, with a timeout of 3 minutes, as follows
1942 type Tcpkeepalivelistener struct { 1943 *net. TcpListener 1944} 1945 1946 func (ln tcpkeepalivelistener) Accept () (c net. Conn, err error) { 1947 TC, ERR: = ln. ACCEPTTCP () 1948 If Err! = Nil { 1949 Return 1950} 1951 TC. Setkeepalive (True) 1952 TC. Setkeepaliveperiod (3 * time. Minute) 1953 return TC, Nil 1954}
not see the keepalive timeout configuration option, the production environment can be banned
for each connection, set the timeout, you can refer to

Client
just looked down, Golang HTTP library client has 5 timeout settings, one is the Timeout, a Transport that is used by the Client Responseheadertimeout, there are three Transport internal Dialer timeout settings, Timeout,keepalive,deadline.
by looking at the Golang code discovery, the time is used if client.timeout > 0 before the HTTP request is executed. Afterfunc defines a fallback function that is called after a timeout, and this function cancels the request in progress.
Dialer Timeout and Deadline are connection timeouts that are used during connection Setup
send requests, receive responses are handled by two threads, respectively. After the request is sent, the timeout in Transport Responseheadertimeout begins, so it refers to the time-out for waiting for a response.
