我目前遇到一个真正让我感到沮丧的问题，我绝对看不到我的代码有任何问题。
我想要实现的是将 http POST 消息发送到我编写的 iDrac 模型（这两个软件都是用 golang 编写的）以控制模型的电源状态，但无论我为请求配置什么，模型总是收到 get带有空体的请求。
我创建并发送请求的功能：
func (iDrac *IDrac) SetPowerstate(powerstate string) error {
//Create reset type json string
var jsonStr = `{"ResetType":"` + powerstate + `"}`
//Create the request with auth header
req, reqErr := iDrac.buildHttpRequestWithAuthorizationHeader(http.MethodPost, "https://"+iDrac.hostAddress+apiBaseURL+apiChassisURL+apiChassisResetAction, jsonStr)
if reqErr != nil {
return fmt.Errorf("COULD_NOT_CREATE_REQUEST: " + reqErr.Error())
}
req.Header.Set("Content-Type", "application/json; charset=UTF-8")
//Make the request
resp, doErr := http.DefaultClient.Do(req)
if doErr != nil {
return fmt.Errorf("COULD_NOT_SEND_POST_REQUEST_TO_IDRAC_API" + doErr.Error())
}
//Check if the request was successful
if resp.StatusCode != 200 {
return fmt.Errorf("COULD_NOT_CHANGE_SERVER_POWER_STATUS_OVER_IDRAC HTTP:" + resp.Status)
}
return nil
}
我用来构建请求的辅助函数：
func (iDrac *IDrac) buildHttpRequestWithAuthorizationHeader(method string, url string, content string) (*http.Request, error) {
req, err := http.NewRequest(method, url, bytes.NewBuffer([]byte(content)))
if err != nil {
return nil, err
}
req.Header.Add("Authorization", "Basic "+iDrac.hashedCredentials)
return req, nil
}
最后是模型处理请求的函数：
func handlePerformReset(w http.ResponseWriter, r *http.Request) {
garbagelog.Log("Handling reset perform request from " + r.RemoteAddr)
if r.Method != http.MethodPost {
garbagelog.Log("Invalid http method! Got " + r.Method + " expected POST")
w.WriteHeader(405)
return
}
if !checkAuthorization(r.BasicAuth()) {
w.WriteHeader(401)
return
}
