Closed 3 years ago.
I have the following JSON
{
"method": "exec",
"params": [
{
"url": "/sys/login/user",
"data": [
{
"user": "MyUsername",
"passwd": "MyPassword"
}
]
}
],
"id": 1,
"ver": "2.0"
}
I'm trying to build this JSON using Powershell, but the output is not correct, below is my code.
$fullJson=#{}
$params=#()
$paramsdata=#()
$paramsdata+=#{"user"="mailapi"}
$paramsdata+=#{"passwd"="**********"}
$params+=#{"url"="/sys/login/user"}
$params+=#{"data"=$paramsdata}
$fullJson.Add("method", "exec")
$fullJson.Add("params",$params)
$fullJson.Add("id", "1")
$fullJson.Add("ver", "2.0")
$JsonBody=$fullJson | ConvertTo-Json
$x=Invoke-WebRequest -Uri https://10.10.10.10/jsonrpc -Body $JsonBody -Method Post
The output is the below
{
"method": "exec",
"params": [
{
"url": "/sys/login/user"
},
{
"data": "System.Collections.Hashtable System.Collections.Hashtable"
}
],
"id": "1",
"ver": "2.0"
}
The problem is DATA properties is not correct format, it should be an a nested array inside the first one, but it seems that its being added as a hashtable.
This problem is the data array should be built like this one below
"params": [
{
"url": "/sys/login/user",
"data": [
{
"user": "MyUsername",
"passwd": "MyPassword"
}
]
But with my code, its being built like this
"params": [
{
"url": "/sys/login/user"
},
{
"data": "System.Collections.Hashtable System.Collections.Hashtable"
}
],
Any help in updating this.
Thanks

Use the -Depth option in ConvertTo-Json :
Specifies how many levels of contained objects are included in the
JSON representation. The default value is 2.
Your desired depth is 4 (object -> params -> data -> username/password) :
$JsonBody=$fullJson | ConvertTo-Json -Depth 4
