To request a remote web page, golang can use the method provided by the client in the net/http package to implement it. I checked some examples on the official website, but there are no comprehensive examples, so I sorted out myself:
get request
func httpGet() {
resp, err := ("http:///demo/?id=1")
if err != nil {
// handle error
}
defer ()
body, err := ()
if err != nil {
// handle error
}
(string(body))
}
Post Request
Way
func httpPost() {
resp, err := ("http:///demo/",
"application/x-www-form-urlencoded",
("name=cjb"))
if err != nil {
(err)
}
defer ()
body, err := ()
if err != nil {
// handle error
}
(string(body))
}
Tips: If you use this method, the second parameter must be set to "application/x-www-form-urlencoded", otherwise the post parameter cannot be passed.
method
func httpPostForm() {
resp, err := ("http:///demo/",
{"key": {"Value"}, "id": {"123"}})
if err != nil {
// handle error
}
defer ()
body, err := ()
if err != nil {
// handle error
}
(string(body))
}
Complex requests
Sometimes you need to set header parameters, cookies and other data during requests to use the method.
func httpDo() {
client := &{}
req, err := ("POST", "http:///demo/", ("name=cjb"))
if err != nil {
// handle error
}
("Content-Type", "application/x-www-form-urlencoded")
("Cookie", "name=anny")
resp, err := (req)
defer ()
body, err := ()
if err != nil {
// handle error
}
(string(body))
}
For the same post request as above, the Content-Type must be set to application/x-www-form-urlencoded so that the post parameters can be passed normally.
If you want to initiate a head request, you can directly use the head method of http client. It is relatively simple, so I won't explain it here.
The above is all the content of this article. I hope it will be helpful to everyone's study and I hope everyone will support me more.
