Got a small problem (I guess). I created c# rest web API on docker swarm environment. Rest API is working properly - tested via the postman. Then I tried to compose Hasura service on the same docker swarm environment. The console is working properly also. The problem is with query action.
Code:
Action definition:
type Query {
getWeatherForecast : [WeatherForecastResonse]
}
New types definition:
type WeatherForecastResonse {
date : String
temperatureC : Int
temperature : Int
summary : String
}
Handler:
http://{api ip}:{api port}/WeatherForecast
While trying to execute query:
query MyQuery {
getWeatherForecast {
temperature
summary
date
temperatureC
}
}
All I got from response is error with json:
{
"errors": [
{
"extensions": {
"internal": {
"error": "invalid json: Error in $: not enough input",
"response": {
"status": 405,
"body": "",
"headers": [
{
"value": "Mon, 14 Jun 2021 13:54:00 GMT",
"name": "Date"
},
{
"value": "Kestrel",
"name": "Server"
},
{
"value": "0",
"name": "Content-Length"
},
{
"value": "GET",
"name": "Allow"
}
]
},
"request": {
"body": {
"session_variables": {
"x-hasura-role": "admin"
},
"input": {},
"action": {
"name": "getWeatherForecast"
}
},
"url": "http://{api ip}:{api port}/WeatherForecast",
"headers": []
}
},
"path": "$",
"code": "unexpected"
},
"message": "not a valid json response from webhook"
}
]
}
I got desired response by using postman white calling: http://{api ip}:{api port}/WeatherForecast (GET method)
Where should I improve, to finally get desired result from rest api?
P.S. hasura version: v2.0.0-alpha.4 (tried also with v1.3.3)
UPDATE: Released a new version of web API. Inside WeatherForecastController included a new method with POST attribute. Query remained the same, but now graphql query returns what I want.
So the question is: Is it possible to call/access web api methods with GET attribute with Hasura action query?
No, currently it's not possible, Hasura always makes POST requests to the action handler:
When the action is executed i.e. when the query or the mutation is called, Hasura makes a POST request to the handler with the action arguments and the session variables.
