https POST 在 golang 中没有按预期工作，但在 Python 中工作正常

Question

我正在尝试从 JIRA REST API 示例中实施 python 代码：

https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-jql/#api-rest-api-3-jql-parse-post

我的 python 代码（按预期工作）：

import requests
from requests.auth import HTTPBasicAuth
import json

url = "https://my-url.com/rest/api/2/search"
auth = HTTPBasicAuth("user1", "pwd1")
headers = {
   "Accept": "application/json",
   "Content-Type": "application/json"
}
payload = json.dumps( {
   "jql": "my-query-string"
}
response = requests.request("POST", url, data=payload, headers=headers, auth=auth, verify=False)
print(json.dumps(json.loads(response.text), sort_keys=True, indent=4, separators=(",", ": ")))

我正在尝试将其转换为如下 golang 代码：

package main
import (
    "io/ioutil"
    "fmt"
    "log"
    "time"
    "net/http"
    "net/url"
}
func main() {
      timeout := time.Duration(500 * time.Second)
      client := http.Client{
          Timeout: timeout,
      }
      req, err := http.NewRequest("POST", "https://my-url.com/rest/api/2/search", nil)
      if err != nil {
          log.Fatalln(err)
      }
      req.SetBasicAuth("user1", "pwd1")
      req.Header.Set("Content-Type", "application/json")
      q := url.Values{}
      q.Add("jql", "my-query-string")
      req.URL.RawQuery = q.Encode()
      fmt.Println(req.URL.String())
      resp, err := client.Do(req)
      if err != nil {
          log.Fatalln(err)
      }
      defer resp.Body.Close()
      
      data, err := ioutil.ReadAll(resp.Body)
      if err != nil {
          log.Fatalln(err)
      }
      log.Println(string(data))

代码构建没有问题。当我运行 go 代码时，我得到这个错误：

   2021/04/17 19:36:31 {"errorMessages":["No content to map to Object due to end of input"]}

我有 2 个问题：

a. How can I fix the above error ?
b. I also want to include concurrency in the same code, i.e the same POST request will actually be executed for 5 different query strings (concurrently) and fetch the results, how can i achieve that ?

Answer 1

对于 POST 请求，您需要将数据作为 json 发送。请注意，在 Go 中设置请求的 Content-Type header 确实 not 自动将您提供的任何内容转换为指定的类型。

发送示例 json.

package main

import  (
    "strings"
    "net/http"
    "io/ioutil"
    "fmt"
)

func main() {
    body := strings.NewReader(`{"jql": "project = HSP"}`)
    req, err := http.NewRequest("POST", "https://your-domain.atlassian.com/rest/api/2/search", body)
    if err != nil {
        panic(err)
    }

    req.SetBasicAuth("email@example.com", "<api_token>")
    req.Header.Set("Accept", "application/json")
    req.Header.Set("Content-Type", "application/json")
    
    resp, err := http.DefaultClient.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    out, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        panic(err)
    }
    fmt.Println(string(out))
}

如果您想使用查询参数，您应该使用带有 GET 方法的端点。

package main

import  (
    "net/http"
    "net/url"
    "io/ioutil"
    "fmt"
)

func main() {
    query := url.Values{"jql": {"project = HSP"}}
    req, err := http.NewRequest("GET", "https://your-domain.atlassian.com/rest/api/2/search?" + query.Encode(), nil)
    if err != nil {
        panic(err)
    }

    req.SetBasicAuth("email@example.com", "<api_token>")
    req.Header.Set("Accept", "application/json")
    
    resp, err := http.DefaultClient.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    out, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        panic(err)
    }
    fmt.Println(string(out))
}
