golang http请求
我的猫叫土豆 人气:0通过go语言实现http请求
http.Post
import ( "net/http" "net/url" ) data := url.Values{"start":{"100"}, "hobby":{"xxxx"}} body := strings.NewReader(data.Encode()) resp, err := http.Post("127.0.0.1:9338", "application/x-www-form-urlencoded", body)
net/http包没有封装直接使用请求带header的get或者post方法,所以,要想请求中带header,只能使用NewRequest方法
http.NewRequest
客户端:
import ( "net/http" "json" "ioutil" ) type Student struct{ id string name string } type StudentReq struct{ id string name string } func main() { stu := Student{ id:"2ed4tg5fe35fgty3yy6uh", name:"amber", } stu,err := json.Marshal(&stu) reader := bytes.NewReader(stu) request,err := http.NewRequest("POST", "http://192.168.1.12:8000/create", reader) request.Header.Set("Content-Type", "application/json") client:=&http.Client{} response,err := client.Do(request) defer response.Body.Close() body,err := ioutil.ReadAll(response.Body) fmt.Printf(string(body)) var stuReq StudentReq err = json.UnMarshal(body, &stuReq) fmt.Println(json.MarshalIndent(stuReq)) }
解析:
- stu,err := json.Marshal(&stu):将stu对象改为json格式
- reader := bytes.NewReader(stu):所以将json改为byte格式,作为body传给http请求
- request,err := http.NewRequest(“POST”, “http://192.168.1.12:8000/create”, reader):创建url
- response,err := client.Do(request):客户端发起请求,接收返回值
- body,err := ioutil.ReadAll(response.Body):读取body的值,类型是byte
- json.MarshalIndent(stuReq):修改json为标准格式
注意(坑):
1、header里的参数是Content-Type,不要写成ContentType
2、【go http: read on closed response body 】如果发送的请求是分为2个func写的,记住defer要在ioutil.ReadAll之后执行,否则报错
gorequest
这种方式适合在url里拼接参数使用param直接传递
"github.com/parnurzeal/gorequest" func main() { resp, body, errs := gorequest.New().Post("http://127.0.0.1/create").Param("ip", "192.168.1.4").EndBytes() if errs != nil || resp.StatusCode >= 300 { log.Errorf("fail to call api with errors %v, %+v", errs, body) } var stuReq StudentReq err = json.UnMarshal(body, &stuReq) fmt.Println(json.MarshalIndent(stuReq)) }
