##uni-app front-end get request is passed to the back-end Chinese value garbled problem

Record some garbled code problems encountered when doing final design

1. At the beginning, I used the get method to transfer values ​​to the back-end springboot. It was very friendly when debugging the h5 page. There was no error and everything went smoothly.

2. However, when I open the mobile phone simulator for real-device debugging. . . An accident came:

The error message displayed by the name in the background is probably like this. I forgot to cut the picture (my name was entered in Chinese: fruit):

/search/itemname?name="

9x8x9c8b5cv"&page=1&num=12, invalid characters found in the request header

Because the get request occurs in the url request header, so I searched everywhere for solutions to garbled characters, but all I found were decoding in the background.

This did not meet my requirements, because the request header was garbled, and it was simply Didn't enter the program, so it's useless.

After all the trouble, I finally felt that it would be better to use

post to request. So:

3. The front end encapsulates the value to be transmitted into an object and passes it to the back end:

It prints out like this:

Send a request in json format to the backend

4. For the backend, change the receiving format to @ RequestBody–that is, the json receiving format (Es7msg is an object I defined and used to receive values)

Then you can successfully get the desired value

I would like to remind everyone that it is best to use post to pass values, which can avoid a lot of garbled characters.
