The above is a comment on the service number access in the demo, which is directly written to the dead. It was originally returned by calling the background interface. Each field in the document has a descriptive effect. Note that the field should not be randomly added, otherwise, the sign will be inconsistent. As for this data, we will not use the official one. We need a service data with the background, so that we can directly initiate the payment. After the payment is successful, the order will be completed.

Special attention should be paid to this issue.

The package path here cannot be changed. It can only be under the root directory of the application package, and the class name cannot be changed. Otherwise, it cannot be called.
