azure - AZ REST DevOps 方法返回 "az : Not a json response"

转载作者：行者123 更新时间：2023-12-03 01:28:19

我在 Windows 10 计算机上运行 powershell 运行 AZ REST 方法时出现问题。该脚本可以工作，甚至可以与用户帐户一起使用，但现在失败了，我不知道为什么。这是进行 AZ REST 调用的核心函数。

function getreleasedefinitionrequest($definitionid, $org, $project)
{
    $requestpath = "/_apis/release/definitions/" + $definitionid + "?api-version=6.0-preview.4"
    $tokeninfo = az account get-access-token | convertfrom-json
    $token = $tokeninfo.accessToken
    $uribase = "https://vsrm.dev.azure.com/" + $org + "/" + $project
    $uri = $uribase+$requestpath
    $authheader = "Authorization=Bearer " + $token
    $result = az rest --uri $uri --headers $authheader | convertfrom-json
    return $result
}

为了确保我使用的帐户具有权限，我明确注销然后重新登录，如图所示

Az logout –username ‘emailusername’
Clear-AzContext
Connect-AzAccount 
az login --only-show-errors --allow-no-subscriptions

运行脚本的 AZ REST 行会产生错误

将输出设置为文件无助于解决此问题。输出也包含在下面。

您认为这次通话出了什么问题吗？

最佳答案

根据错误，您没有提供正确的访问 token 。因为 Azure CLI az account get-access-token 只能获取访问 token 来获取 Azure 资源或 Azure AD 资源。它不能用于获取 Azure DevOps 访问 token 。更多详情请引用here和 here .

如果您想使用 CLI 来管理 Azure DevOps，可以使用 Azure DevOps CLI 。例如，如果要获取发布定义，可以使用命令 az pipelines release definition show .

更新

如果您想使用PAT调用Azure Devops Rest API，请引用以下脚本

$username =""
$password="<your PAT>"
$tokens = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))


$authheader = "Authorization=Basic " + $tokens 
$res = az rest --uri "https://vsrm.dev.azure.com/jim0375/test/_apis/release/definitions?api-version=6.0" --headers  $authheader 
$res
