How to get GraphQL error objects using GraphQLView in 2.0.0?

检查 2.0.0 版本中的 GraphQLView 重构，尤其是 dispatch_request，并将其与 issue 中描述的之前的 execute_graphql_request 路径进行比较。确定重构后的 view 是否能够为 Raygun 报告暴露原始错误对象和堆栈跟踪；完成的标准是错误在 JSON 序列化之前仍然可用。

Hello,

We are using this library to add graphql support to our flask app. We used to have version 1.3.1 installed and the following view code was working correctly:

class AppGraphQLView(GraphQLView):
    def execute_graphql_request(self, *args, **kwargs):
        """Extract any exceptions and send them to Raygun"""
        result = super().execute_graphql_request(*args, **kwargs)

        if result is not None and result.errors:
            send_errors_to_raygun(result.errors)

        return result

We've recently updated to version 2.0.0 of this library, and this caused our errors to not be sent to raygun, because our function is no longer called.. I discovered that the whole of GraphQLView has been refactored to not include execute_graphql_request anymore so I tried using dispatch_request instead.

However, dispatch_request returns a json object and any errors have only the message, no stacktrace or any other important information we would need to send to raygun.

I have tried to replicate this functionality without overwriting GraphQLView's implementation of execute_graphql_request, by using middleware instead:

def error_reporting_middleware(next, root, info, **kwargs):

    result = next(root, info, **kwargs)

    if result.is_rejected:
        send_errors_to_raygun([result.reason])

    return result

This kinda works, but I was wondering if there is a similar way to do it using the refactored GraphQLView in v2.0.0.

Thanks!
