node.js - Azure DevOps REST API - 创建工作项 - "A value is required"

Question

我正在尝试使用 Azure DevOps REST API 创建一个工作项。我已经能够做其他事情，比如运行 WIQL 查询，但是当我尝试创建一个工作项时，我得到了这个神秘的三重错误:

A value is required but was not present in the request
A value is required but was not present in the request
A value is required but was not present in the request

这是完整的回应。

{
    "count": 1,
    "value": {
        "Message": "A value is required but was not present in the request.\r\nA value is required but was not present in the request.\r\nA value is required but was not present in the request.\r\n"
    }
}

这是我正在尝试做的，遵循 documentation尽我所能。
注意:正如接受的答案所说，问题是一个错字， &紧接着 ?在网址中。由于这些示例在其他方面有效，为了任何想要复制和粘贴的人的利益，我已经修复了错字。
NodeJS 中的最小测试用例

const fetch = require('node-fetch');

const username = '[username]';
const password = '[personal access token]'
const organization = '[organization]';
const project = '[project]'

const authorizationHeader = `Basic ${Buffer.from(
    `${username}:${password}`
  ).toString('base64')}`

const body = [
    { 
        "op":"add",
        "path":"/fields/System.Title",
        "value":"TestCreateWI"
    }
];


  fetch(`https://dev.azure.com/${organization}/${project}/_apis/wit/workitems/$Task?api-version=6.0`, {
    method: 'POST',
    headers: {
      Authorization: authorizationHeader,
      'Content-Type': 'application/json-patch+json',
    },
    body: JSON.stringify(body),
  }).then(async (response) => {    
    console.log(await response.text())
  });

使用 CURL 的相同请求

curl 'https://dev.azure.com/MyOrganization/MyProject/_apis/wit/workitems/$Task?api-version=6.0' \
  -H 'Authorization: Basic [redacted]' \
  -H 'Content-Type: application/json-patch+json' \
  --data-binary '[{"op":"add","path":"/fields/System.Title","value":"Test"}]'

来自浏览器的相同请求
登录 DevOps，让浏览器指向 https://dev.azure.com/YourProject/YourOrganization .然后打开 Dev Tools (F5) 并将此代码粘贴到 JS 控制台中。

const body = [
    { 
        "op":"add",
        "path":"/fields/System.Title",
        "value":"TestCreateWI"
    }
];

fetch(`${document.URL}/_apis/wit/workitems/$Task?api-version=6.0`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json-patch+json',
  },
  body: JSON.stringify(body),
}).then(async (response) => {    
  console.log(await response.text())
});

我知道它正在读取我的请求，因为如果我将“op”更改为无效值，则会出现不同的错误。我错过了什么？

你的网址有错别字。我在 postman 中复制了该行为并通过修复 URL 来解决它。在 PowerShell 中调用“工作”的大多数其他答案都没有复制您的错字。
您指定了 https://dev.azure.com/${organization}/${project}/_apis/wit/workitems/$Task?&api-version=6.0它不应该在 api 版本之前有额外的 & https://dev.azure.com/${organization}/${project}/_apis/wit/workitems/$Task?api-version=6.0
