This is a very simple guide to the request library. Just want to be easy to do what I would like to do. So I build it.
You just need to copy and paste the command to the terminal and press the Enter key.
go get -u github.com/tansoz/request
First, You need import the library with the import statement.
import "github.com/tansoz/request"Make sure the library was imported before writing a request with the library.
Use the library to send a simple GET request
if resp := request.Get("https://httpbin.org/get", map[string]interface{}{
"id":1515,
"method":"get"
}); resp.Error() == nil {
var tmp bytes.Buffer
tmp.ReadFrom(resp.Readable())
fmt.Println(tmp.String())
} else {
fmt.Println(resp.Error())
}Result:
{
"args": {
"id": "1515",
"method": "get"
},
"headers": {
"Accept-Encoding": "gzip",
"Host": "httpbin.org",
"User-Agent": "request/1.1.2",
"X-Amzn-Trace-Id": "Root=1-61928190-67740ba50929357a16b5f917"
},
"origin": "123.154.60.166",
"url": "https://httpbin.org/get?id=1515&method=get"
}Use the library to send a simple POST request
if resp := request.Post("https://httpbin.org/post", map[string]interface{}{
"id": 1515,
"foo": "bar",
}); resp.Error() == nil {
var tmp bytes.Buffer
tmp.ReadFrom(resp.Readable())
fmt.Println(tmp.String())
} else {
fmt.Println(resp.Error())
}Result:
{
"args": {},
"data": "",
"files": {},
"form": {
"foo": "bar",
"id": "1515"
},
"headers": {
"Accept-Encoding": "gzip",
"Content-Length": "15",
"Content-Type": "application/x-www-form-urlencoded; charset=utf-8",
"Host": "httpbin.org",
"User-Agent": "request/1.1.2",
"X-Amzn-Trace-Id": "Root=1-61928192-327e74387dd38edc28ebdcb3"
},
"json": null,
"origin": "123.154.60.166",
"url": "https://httpbin.org/post"
}Use the library to send a simple POST request
if resp := request.New(
option.POST,
option.URL("https://httpbin.org/post"),
).Go(body.MultipartBody([]body.Field{
body.FileBodyField("files", "testfile.txt", "go.sum", "text/plain", 0, -1, nil),
}, "", nil)); resp.Error() == nil {
var tmp bytes.Buffer
tmp.ReadFrom(resp.Readable())
fmt.Println(tmp.String())
} else {
fmt.Println(resp.Error())
}Result:
