我正在尝试编写一些 PowerShell 函数来与我们的 Atlassian JIRA 系统（JIRA 5.2，下载版）进行交互。不幸的是，我通过反复试验发现Invoke-RestMethod似乎不起作用（不支持身份验证标头），因此我编写了一个名为 Invoke-JiraMethod 的简单函数。我可以确认此方法适用于 GET 请求；我已经能够使用它来让 Jira 对象满足我的心愿。但是，一旦我尝试创建问题，我就开始收到 HTTP 400 / Bad request 错误。

我已按照此处的步骤获取问题元数据，并且正在填写输入对象中的所有必填字段。谁能帮我弄清楚如何解决 400 错误？如果需要，我可以提供更多信息 - 我只是不想超出问题的描述。:)

我收到错误 400，因为我放入 json 数据的问题类型 ID 号没有映射到任何东西。提琴手帮我诊断。

我使用这段代码来确定通过invoke-restmethod的-Headers选项对jira进行身份验证：http: //poshcode.org/3461

然后我将 json 数据放入一个 here 字符串中，然后运行 ​​invoke-restmethod。

下面的代码位。用您从 jira 管理员获得的实际项目和问题类型 ID 替换“任何有效的...类型 ID 号”。

$uri = "$BaseURI/rest/api/2/issue" 


    $jsonString = @'
{
    "fields": {
       "project":
       {
          "id": "any valid project id number"
       },
       "summary": "No REST for the Wicked.",
       "description": "Creating of an issue using ids for projects and issue types using the REST API",
       "issuetype": {
          "id": "any valid issue type id number"
       }
   }
}  
'@  


        $headers = Get-HttpBasicHeader $Credentials

        Invoke-RestMethod -uri $uri -Headers $headers  -Method Post -Body $jsonString -ContentType "application/json"
