Interface for "Instant query":

Both RequestData and DataSign are signed data. The other three are written in a fixed way.

Express Bird api realizes real-time logistics query

1. First of all, there must be an express bird account, according to the requirements of the other side, improve the user application.

two。 Activate services according to your own needs

3. Go to "my API interface", understand the design requirements according to the development documentation in "interface", download the official demo, and edit the code that suits you.

[instant query] Code implementation

1. By modifying the official demo code, I have separated a delivery class here to improve its applicability

two。 Introduce class files, instantiate and test
