Golang HTTP.Handler forgraphl-go

package mainimport ("net/http""github.com/graphql-go/handler")funcmain() {schema,_:= graphql.NewSchema(...)h:= handler.New(&handler.Config{Schema:&schema,Pretty:true,GraphiQL:true,})http.Handle("/graphql",h)http.ListenAndServe(":8080",nil)}

h:=handler.New(&handler.Config{Schema:&schema,Pretty:true,GraphiQL:false,Playground:true,})

The handler will accept requests withthe parameters:

• query: A string GraphQL document to be executed.

• variables: The runtime values to use for any GraphQL query variablesas a JSON object.

• operationName: If the providedquery contains multiple namedoperations, this specifies which operation should be executed. If notprovided, an 400 error will be returned if thequery contains multiplenamed operations.

GraphQL will first look for each parameter in the URL's query-string:

/graphql?query=query+getUser($id:ID){user(id:$id){name}}&variables={"id":"4"}

If not found in the query-string, it will look in the POST request body.Thehandler will interpret itdepending on the providedContent-Type header.

• application/json: the POST body will be parsed as a JSONobject of parameters.

• application/x-www-form-urlencoded: this POST body will beparsed as a url-encoded string of key-value pairs.

• application/graphql: The POST body will be parsed as GraphQLquery string, which provides thequery parameter.
