无法使用PowerShell Curl命令处理HTTP删除请求

Question

PS C:> $postParams = @{eventId='235'}
PS C:> curl -Method DELETE -Uri http://localhost:8080/eventlist/api/v1/events -Body $postParams
curl : Error deleting event
At line:1 char:1

   eption
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

但是，如果我想删除

curl -Method DELETE -Uri http://localhost:8080/eventlist/api/v1/events?eventId=235

它有效

为什么不使用$postParams？

Answer 1

This is not working
    PS C:Users> $postParams = "{eventId='$eventId'}"
    PS C:Users> Invoke-WebRequest -Method POST -Uri "http://localhost:8080/eventlist/api/v1/events" -Body $postParams
Invoke-WebRequest : Error creating event
At line:1 char:1
+ Invoke-WebRequest -Method POST -Uri "http://localhost:8080/eventlist/api/v1/even ...

   eption
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

这在工作

PS C:> Invoke-WebRequest -Method DELETE -Uri 'http://localhost:8080/eventlist/api/v1/events?eventId=235'

这是失败的，因为删除不是邮政命令。

未经测试的代码。

要在PowerShell中重新创建DELETE，您的语法必须为：

$eventId=235
Invoke-WebRequest -Method DELETE -Uri "http://localhost:8080/eventlist/api/v1/events?eventId=$eventId"

原始帖子

这与命令行应用程序卷曲有关，而不是powershell curl，它是Invoke-WebRequest

的ALIS

失败的原因有两个，第一个是删除不是邮政命令。第二，您正在尝试将PowerShell对象传递到命令行应用程序中。

未经测试的代码。

要在PowerShell中重新创建DELETE，您的语法必须为：

$eventId=235
&curl -Method DELETE -Uri "http://localhost:8080/eventlist/api/v1/events?eventId=$eventId"

POST命令可以像这样（取决于您的端点）：

$eventId=235
$postParams = "{eventId='$eventId'}"
&curl -H "Content-Type: application/json" -X POST -d $postParams 'http://localhost:8080/eventlist/api/v1/events'

注意，身体是JSON字符串，而不是PowerShell对象。
