The request interface field value contains a + number. How can this problem be solved?

For example, after a slash (/) or urlencode, the actual received data is: % 252f (Android device),/(Apple device). Is this an error? Android urlencode twice, and then urldecode again after iosurlencode. all get requests, such as the slash (/) and urlencode, actually receive data: % 252f (Android device) And/(Apple device) logs. Can this be solved?
Android urlencode twice, and ios urlencode later urldecode.

What do you want to ask? The difference in accepting data means that your HTTP request has different parameters, and you have not provided any information about the request library you are using and the Code for submitting the request method. You do not know how to help you.

In addition, why does the GET request contain Content-Type?

Does iOS directly use nsstring to spell out a string request?
