It had better to define the those fields in a class together.

could you clarify what you mean for this one? I moved the queueUrl field closer to these methods that use it, but I'm not sure if that's what you are suggesting. Are you saying I should move these request fields into a new class?

What I actually mean is that all the fields in a class are defined in a piece of code, and then it is followed by some method definitions. I personally think this will make a class look clearer, for example, it will be easier to check whether some fields are used or whether the writing complies with the specification：）

that makes sense, thank you for the explanation
