DSL does not provide expected argument validation

Bắt đầu với dsl.dsl_gql và so sánh hành vi của nó với gql.gql bằng bản tái hiện API countries trong Issue này. Theo dõi cách các đối số của truy vấn DSL được xử lý và xác minh rằng bộ lọc không đúng định dạng ở bước 5 tạo ra một GraphQLError tương đương thay vì trả về các kết quả chưa được lọc.

Describe the bug

• When creating a query with gql.gql(), the query string is checked for invalid arguments, and raises an exception if any are found. (expected behavior)
• When creating a query with gql.dsl.dsl_gql(), the arguments are not checked, causing unexpected return values. (unexpected behavior)

I've been able to recreate this using the countries api used in the docs.

To Reproduce

Jump to step 5 to see the actual improper behavior.

1. Set up the transport/client.

   import json
   
   import gql
   from gql.transport.requests import RequestsHTTPTransport as Transport
   from gql import dsl
   
   url = "https://countries.trevorblades.com/"
   
   transport = Transport(url=url)
   client = gql.Client(transport=transport, fetch_schema_from_transport=True)
   
   # Fetch the schema (lemme know if there's a recommended approach for this).
   client.connect_sync()
   client.close_sync()
   ds = dsl.DSLSchema(client.schema)
   

2. Run a good query using strings.

   good_query_str = gql.gql(
       """
       query {
           continents (filter:{code:{eq:"AN"}}) {
               code
               name
           }
       }
       """
   )
   result = client.execute(good_query_str)
   print(json.dumps(result, indent=2))
   

   Result:

    {
    "continents": [
        {
        "code": "AN",
        "name": "Antarctica"
        }
    ]
    }
   

3. Run a bad query using strings. The only change here is using 'AN' directly as an argument to code, instead of providing the eq directive.

   bad_query_str = gql.gql(
       """
       query {
           continents (filter:{code:"AN"}) {
               code
               name
           }
       }
       """
   )
   result = client.execute(bad_query_str)
   print(json.dumps(result, indent=2))
   

   Result:

   GraphQLError: Expected value of type 'StringQueryOperatorInput', found "AN".
   
    GraphQL request:3:34
    2 |     query {
    3 |         continents (filter:{code:"AN"}) {
    |                                  ^
    4 |             code
   

4. Run a good query using DSL.

   good_query_dsl = dsl.dsl_gql(
       dsl.DSLQuery(
           ds.Query.continents(
               filter={
                   'code': {'eq': 'AN'}
               }
           ).select(
               ds.Continent.code,
               ds.Continent.name,
           )
       )
   )
   result = client.execute(good_query_dsl)
   print(json.dumps(result, indent=2))
   

   Result:

    {
    "continents": [
        {
        "code": "AN",
        "name": "Antarctica"
        }
    ]
    }
   

5. Run a bad query using DSL. Same deal, just remove the 'eq' level of filter specification. Note that the result is an unfiltered response.

   bad_query_dsl = dsl.dsl_gql(
       dsl.DSLQuery(
           ds.Query.continents(
               filter={
                   'code': 'AN'
               }
           ).select(
               ds.Continent.code,
               ds.Continent.name,
           )
       )
   )
   result = client.execute(bad_query_dsl)
   print(json.dumps(result, indent=2))
   

   Result:

    {
    "continents": [
        {
        "code": "AF",
        "name": "Africa"
        },
        {
        "code": "AN",
        "name": "Antarctica"
        },
        {
        "code": "AS",
        "name": "Asia"
        },
        {
        "code": "EU",
        "name": "Europe"
        },
        {
        "code": "NA",
        "name": "North America"
        },
        {
        "code": "OC",
        "name": "Oceania"
        },
        {
        "code": "SA",
        "name": "South America"
        }
    ]
    }
   

Expected behavior

Step 5 should raise an equivalent exception to step 3.
