Some QT character conversion

Note: In windows, "we" is written in the IE Address Bar"

The message sent to the server becomes "% Ce % D2 % C3 % C7 ",

Is the form of converting gb2312 to URL percent code. In ubuntu, "we" is written in the Firefox address bar and sent to the server as "% E6 % 88% E4 % BB % ac ",

Is the form of converting UTF-8 to URL percent code

The following is a summary of the conversion code: (my environment: ubuntu10.10 qt4.6.2) 01

// Ubuntu Firefox http get "we" % E6 % 88% 91% E4 % BB % AC UTF-802

// Windows ie http get "" % Ce % D2 % C3 % C7 gb231203

Char * s = "0x us ";

// UTF-8 char *

Qstring strt1 = "0x % Ce % D2 % C3 % C7 ";

// Gb2312 URL percent code 05

Qbytearray bat1, bat2, bat3, bat4;

Percentencoding2bytearray (strt1, bat1); // self-written function, since qurl: frompercentencoding only applies to URL encoding of the UTF-8

Strt1 = qtextcodec: codecforname ("gb2312")-> tounicode (bat1); // gb2312's qbytearray convert to qstring Unicode

Bat2 = qtextcodec: codecforname ("gb2312")-> fromunicode (strt1); // qstring Unicode convert to gb2312 qbytearray

Qstring strt2, strt3, strt4, strt5;

Strt2 = qtextcodec: codecforname ("UTF-8")-> tounicode ("0x we"); // UTF-8 char * to Unicode qstring

Bat3 = qtextcodec: codecforname ("UTF-8")-> fromunicode (strt2); // Unicode qstring to UTF-8 qbytearray

Strt3 = qtextcodec: codecforname ("UTF-8")-> tounicode (s); // UTF-8 char * to Unicode qstring

Strt4 = qurl: topercentencoding (qstring: fromlocal8bit (s); // UTF-8 char * To percentencoding (UTF-8 format)

Strt5 = qurl: frompercentencoding ("0x % E6 % 88% 91% E4 % BB % ac"); // percentencoding (UTF-8 format) to Unicode

Bat4 = qtextcodec: codecforname ("gb2312")-> fromunicode (qtextcodec: codecforname ("UTF-8")-> tounicode (s); // UTF-8 char * To gb2312 qbytearray

A small function (for gb2312 URL percent conversion) is provided)

Void percentencoding2bytearray (qstring strinput, qbytearray & bytearrayout)

{

For (INT I = 0; I <strinput. Length ();)

{

If (0 = qstring: Compare (strinput. mid (I, 1), qstring ("% ")))

{

If (I + 2) <strinput. Length ())

{09 bytearrayout. append (strinput. mid (I +). toshort ));

I = I + 3; 11} 12 else13 {14 bytearrayout. append (strinput. mid (I, 1 ));

I ++;

}

}

Else

{

Bytearrayout. append (strinput. mid (I, 1 ));

I ++;

}

}

// For end

} // Percentencodin
