URL special character escape
The special meanings and basic coding rules of some characters in URL are as follows:
1, space with plus sign (+)
2. A forward slash (/) separates directories and subdirectories.
3. Question mark (? ) separate the website and query.
4. The percent sign (%) develops special characters.
5, # Specify bookmark
6. The ampersand separates the parameters
If it needs to be used in URL, these special characters need to be replaced with corresponding hexadecimal values.
+ %2B
/ %2F
%3F
% %25
# %23
& amp%26

At this time, you can try to escape with URL special characters.
Use the encodeURI () function of JS or directly change it to the corresponding hexadecimal value.
Look at the introduction of encodeURI function on the internet, which is also about URI escape.
