期望结果:

• 正确获取 itop rest api 返回的工单数据

当我使用 Python 的 requests 库时，这一切都很正常，获取数据成功（如果我覆盖默认 headers，获取的结果如 golang 版本的一样。

这是 Python 的代码:

#!/usr/bin/python3
import requests, json
HOST = “http://192.168.17.22:8096/itop/webservices/rest.php?version=1.3”
json_str = json.dumps({
“operation”:
“core/get”,
“class”:
“UserRequest”,
“key”:
“SELECT UserRequest WHERE operational_status = ‘ongoing’”,
“output_fields”:
“request_type,servicesubcategory_name,urgency,origin,caller_id_friendlyname,impact,title,description”,
})
json_data = {
“auth_user”: “admin”,
“auth_pwd”: “goodjob@123”,
“json_data”: json_str
}
secure_rest_services
def get():
r = requests.post(HOST, data=json_data)
return r
if name == “main”:
result = get()
print(result.json())

输出

{'objects': {'UserRequest::7': {'code': 0, 'message': '', 'class': 'UserRequest', 'key': '7', 'fields': {'request_type': 'service_request', 'servicesubcategory_name': '钉钉权限开通', 'urgency': '4', 'origin': 'portal', 'caller_id_friendlyname': 'x 阿里合作项目负责人', 'impact': '1', 'title': '溫江|A-222|wb-xxxxxxxx', 'description': '<p>this is a test approve...</p>'}}, 'UserRequest::6': {'code': 0, 'message': '', 'class': 'UserRequest', 'key': '6', 'fields': {'request_type': 'service_request', 'servicesubcategory_name': '钉钉权限开通', 'urgency': '3', 'origin': 'portal', 'caller_id_friendlyname': 'x 阿里合作项目负责人', 'impact': '1', 'title': '成都|Xa-111|wb-xx111111', 'description': '<p>這是一個測試用的用戶需求</p>'}}}, 'code': 0, 'message': 'Found: 2'}

下面时 golang 版本的 post 请求

主函数：

package main
import (
“bytes”
“encoding/json”
“fmt”
“io/ioutil”
“log”
“net/http”
“strconv”
)
// 釘釘應用程序的 agentid
const (
ITOP_URL = http://192.168.17.22:8096/itop/webservices/rest.php?version=1.3
)
func main() {
request_auth := new(RequestAuth)
request_data := new(RequestData)
request_auth.AuthUser = “admin”
request_auth.AuthPwd = “goodjob@123”
request_data.Operation = "core/get"
request_data.Class = "UserRequest"
request_data.Key = "SELECT UserRequest WHERE operational_status = \"ongoing\""
request_data.OutPutFields = "request_type,servicesubcategory_name,urgency,origin,caller_id_friendlyname,impact,title,description"
req_data, err := json.Marshal(request_data)
if err != nil {
	panic(err)
}
request_auth.JsonData = string(req_data)

jsonData, err := json.Marshal(request_auth)
if err != nil {
	panic(err)
}
reader := bytes.NewReader(jsonData)
result := Post(ITOP_URL, reader)
fmt.Println(string(result))
}
func Post(url string, reader *bytes.Reader) []byte {
request, err := http.NewRequest(“POST”, url, reader)
if err != nil {
panic(err)
}
request.Header.Set(“Content-Type”, “application/json”)
request.Header.Set(“Content-Length”, strconv.Itoa(reader.Len()))
client := http.Client{}
resp, err := client.Do(request)
if err != nil {
log.Fatal(err.Error())
}
defer resp.Body.Close()
respBytes, _ := ioutil.ReadAll(resp.Body)
return respBytes
}

post 携带的数据模型

package main
// UserRequest structure
type Base struct {
Code    int    json:"code"
Message string json:"message"
}
type Fileds struct {
RequestType            string json:"request_type"
ServiceSubcategoryName string json:"servicesubcategory_name"
Urgency                string json:"urgency"
Origin                 string json:"origin"
CallerIdFriendlyName   string json:"caller_id_friendlyname"
Impact                 string json:"impact"
Title                  string json:"title"
Description            string json:"description"
}
type ResponseContent struct {
Code    int    json:"code"
Message string json:"message"
Class   string json:"class"
Key     string json:"key"
Filed   Fileds json:"fields"
}
type Response struct {
Base
Object map[string]ResponseContent json:"objects"
}
// Request api data struct
type RequestData struct {
Operation    string json:"operation"
Class        string json:"class"
Key          string json:"key"
OutPutFields string json:"output_fields"
}
type RequestAuth struct {
AuthUser string json:"auth_user"
AuthPwd  string json:"auth_pwd"
// JsonData RequestData json:"json_data"
JsonData string json:"json_data"
}

输出:

{"code":5,"message":"Error: Missing parameter 'auth_user'"}

我猜这应该是 itop 需要 post 请求携带某个 header ？但我折腾了太久，直到实在没有办法才发帖求助。

求大佬们指点，(拜谢
