Encoded Url in Browser Address Bar- 1 min
Lately I was sending GET request to an address with four parameters at least, there is nothing special except three points I’d like to address here:
Encode Query String
encodeURI, decodeURI, and
However, it bugs me that the
encodeURI method does not encode some very common characters like
=(the rest are
; , / ? : @ + $), this makes using encodeURI to handle query strings at one time impossible, so basically I use
encodeURIComponent(which does encode & or =) to handle query string encoding while assemble the whole URL.
There is one key-value pair
someUrl="http://www.abc.com/x=1&y=2", it is a little bit different than key-value pairs like ‘x=1&y=2’, if you don’t use encodeURIComponent on this one:
Long url in address bar
It is likely that the encoded query value is very long (especially there is Chinese characters in query), although according to RFC, there is no limit to the length of an URI, but limitations exist in various browsers, generally speaking, URL over 2000 characters will not work.
GET v.s. POST request
After all, I think it would be much better to avoid really long query string in URL by sending GET request, in that case, send data in POST request body would be a better choice.
