Making a PowerShell POST request if a body param starts with '@'

Question

I want to make a POST request in PowerShell. Following is the body details in Postman.

{
  \"@type\":\"login\",
  \"username\":\"xxx@gmail.com\",
  \"passwor         


        

Answer 1

Use Invoke-RestMethod to consume REST-APIs. Save the JSON to a string and use that as the body, ex:

$JSON = @'
{"@type":"login",
 "username":"xxx@gmail.com",
 "password":"yyy"
}
'@

$response = Invoke-RestMethod -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"

If you use Powershell 3, I know there have been some issues with Invoke-RestMethod, but you should be able to use Invoke-WebRequest as a replacement:

$response = Invoke-WebRequest -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"

If you don't want to write your own JSON every time, you can use a hashtable and use PowerShell to convert it to JSON before posting it. Ex.

$JSON = @{
    "@type" = "login"
    "username" = "xxx@gmail.com"
    "password" = "yyy"
} | ConvertTo-Json
