1、SendFile 发送文件：

Type(“multipart”) 必须放在Post 之后才起作用

2、发送单一文：

件request := gorequest.New()
resp, contents, errs := request.Post(s.PostUrl).
Type(“multipart”).
Send(s.Datas).
SendFile(FilePath,”文件名”,”请求字段”).
End()

3、解决访问https 出现 x509: certificate signed by unknown authority

request := gorequest.New()
resp, contents, errs := request.Post(s.PostUrl).
   Type("multipart").
   Timeout(5*time.Second).
   Send(s.Datas).
   SendFile(FilePath, "file", "file").
   End()
fmt.Println(resp, contents, errs)

Post https://127.0.0.1:2443/test/: x509: certificate signed by unknown authority

解决方法：

request := gorequest.New()  
request.TLSClientConfig(&tls.Config{InsecureSkipVerify: true}) //解决HTTPS
resp, contents, errs := request.Post(s.PostUrl).
   Type("multipart").
   Timeout(5*time.Second).
   Send(s.Datas).
   SendFile(FilePath, "file", "file").
   End()
fmt.Println(resp, contents, errs)

4、解决golang https请求提示x509: certificate signed by unknown authority

https://studygolang.com/articles/12217

import (
    "crypto/tls"
    "log"
    "net/http"
)
func get(url string, headers map[string]string) *http.Response {
    tr := &http.Transport{    //解决x509: certificate signed by unknown authority
        TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
    }
    client := &http.Client{
        Timeout:   15 * time.Second,
        Transport: tr,    //解决x509: certificate signed by unknown authority
    }
    req, err := http.NewRequest("GET", url, nil)
    for k, v := range headers {
        req.Header.Add(k, v)
    }
    if err != nil {
        log.Println(err.Error())
        return nil
    }
    resp, err := client.Do(req)
    if err != nil {
        log.Println(err.Error())
        return nil
    }
    return resp
}
