ConvertFrom-Json :无效的JSON原语

Question

我正在尝试将此命令作为部署后操作行内脚本在azure vsts发布管道中执行：

powershell -command "&{
 $json = Get-Content '.\appsettings.json' -raw | ConvertFrom-Json;
 $data = '{"allowedUrls" : [{ "host" : "someUrl","protocol" : "https"},{ "host":"localhost:44394","protocol" : "https"}]}' | ConvertFrom-Json;
 $json.allowedUrls = $data.allowedUrls;
 $json | ConvertTo-Json -Depth 32 | Set-Content '.\appsettings.json'; 
 }" 

当我在powershell中运行它时，它在本地工作，但在azure上我得到：

 Standard error from script: 
2020-06-09T08:27:08.5939074Z ConvertFrom-Json : Invalid JSON primitive: someUrl.

可能出了什么问题？

当像$data = '{"allowedUrls" : [{"host" :"someUrl","protocol" :"https"},{"host":"localhost:44394","protocol" :"https"}]}' | ConvertFrom-Json;这样的转义字符串出现时

我得到了

Standard error from script:

Answer 1

这就是解决方案：

powershell -command "&{
    $json = Get-Content '.\appsettings.json' -raw | ConvertFrom-Json;
     $data = '$(additionalAllowedUris)' | ConvertFrom-Json;
     $json.additionalAllowedUris= $data.SyncRoot;
     $json | ConvertTo-Json -Depth 32 | Set-Content '.\appsettings.json';
    }"

和管道中的变量：

[{ \"host\" : \"someUrl\",\"protocol\" : \"https\"},{ \"host\":\"localhost:44394\",\"protocol\" : \"https\"},{ \"host\":\"someUrl2\",\"protocol\" : \"https\"}]
