替换字符串 [英] replace string
问题描述
我有一个网址，这是一个字母*
char * url =" / url =％2Fhome％2Fsumit％2Fpackages％ 2Fmyxml.xml" ;;
当我将此URL发送到http服务器时，它就像 -
" / url = / home / sumit /pacakges/myxml.xml"
但当它通过http服务器获取时它将''/''转换为''％2F''我必须
重新转换为''/''
i做了很多字符串操作，但我没有得到真正的字符串，
我还在尝试。任何人都可以请你知道如何更换''％2F''
''/''
谢谢

char url [] = " /url=%2Fhome%2Fsumit%2Fpackages%2Fmyxml.xml" ;;
char * p;
while（（p = strstr（url，"％2F"） ;））！= NULL）{
* p =''/'';
memmove（p + 1，p + 3，strlen（p + 2）） ;
}
注意第一行的变化。还要注意，这不是特别高效的b $ b，也不是非常灵活 - 但这就是你要求的b $ b，所以...

Er ********* @ sun.com
char url[] = "/url=%2Fhome%2Fsumit%2Fpackages%2Fmyxml.xml";
char *p;
while ((p = strstr(url, "%2F")) != NULL) {
*p = ''/'';
memmove (p+1, p+3, strlen(p+2));
}
Note the change in the first line. Also note that this is not
especially efficient, nor tremendously flexible -- but it''s what you
asked for, so ...

它可能看起来像这样，但如果字符串是使用％2F定义的然后我会希望这是实际传输的内容。
It may look like that, but if the string is defined using "%2F" then I
would expect that to be what is actually transmitted.
但是当它被http服务器获取时它会转换''/''到''％2F''我必须将b $ b重新转换为''/''

告诉我们您的尝试。执行此处理并不困难，只需扫描
字符串为％并将以下两个字符视为十六进制
数字表示所需字符然后复制其余部分
string（虽然仍在寻找％字符）。当然，你还有
来决定如何处理无效输入。
