Extracting name and variables from GraphQL post request body

[svoruganti]

Hi,

Using ASP.Net core middleware, I am capturing GraphQL post request body as string. I would like to extract name and variables from the request string. Are there any built in classes that would allow me to do that. For example, if I have a string representation of following request:

mutation createUser {
  user(
    input: {
      name: "test name"
      emailAddress: "[[email protected]](mailto:[email protected])"
    }
  ) {
    id
  }
}

From the above request string, I would like to extract 'user' and variables name and emailAddress along with values. We can extract the data using HotChocolate request middleware, but I want to find out if it is possible to do with http request string/stream i.e., without using HotChocolate request middleware.

Yes you can use Utf8GraphQLParser.Parse to parse GraphQL string into a DocumentNode. Then you have the AST and can read the different parts easily
