Upload URL encoding and receiving decoding parameters to asp and Asp.net pages

For example, the URL transmitted by asp.net in Get mode is: "WebPage. asp? Str = "+ HttpUtility. UrlEncode (str)
The decoding method is HttpUtility. UrlDecode (Request. QueryString ["str"]. ToString (). Trim ())
The asp Get method is transmitted as "webPage. aspx? Str = "+ server. urlencode (str) encoding is inconsistent

Solution: transfer "WebPage. aspx?" using Get in asp? Str = "+ server. urlEncode (server. URLpathencode (str ))
Asp.net GET transmission parameter: "WebPage. aspx? Str = "+ HttpUtility. UrlEncode (str, System. Text. Encoding. GetEncoding (" gb2312 "))
Asp.net GET method receiving parameter: str = HttpUtility. urlDecode (Request. queryString ["str"]. toString (). trim (), System. text. encoding. getEncoding ("gb2312 "))
