recently use jquery"s ajax to send Json data to the Java background, because the default requested ContentType is application/x-www-form-urlencoded;charset=UTF-8, resulting in an extra "=" at the end of the Json data received by the background.
now that I know that changing ContentType to application/json;charset=utf-8 can solve this problem, I"d like to ask why there is an extra = by default. Do you want to take a look at the source code? I don"t know how to look at it yet.
application/x-www-form-urlencoded;charset=UTF-8 is a key-value pair structure, that is, something like this:
name=tim&age=20 is because the content is regarded as key, while the value is empty
, and it is right to transfer data with the correct content-type, which is more friendly to the framework
problem description background written by others, I didn t write the interface before I wrote the interface myself and then called it with ajax to get no data. I don t know what went wrong. I don t know exactly where to put the js and html files ...
