问题描述
我一直在Unicode模式的客户端应用程序中使用wininet.通常，它可以正常工作.
我将下载内容放入char *缓冲区中，并在每个InternetReadFile上构建了一个std :: string.由于我认为我正在获取UTF8编码的网页，因此在下载全部内容后，我将使用CA2W(buffer，CP_UTF8)进行转换.
但是，我想知道如何知道下载文件的字符集编码是什么?
我知道/if/是UTF8，我应该将其转换.但是，如果不是UTF8，该怎么办?如果是UTF16或ISO-8859-1或ANSI怎么办?
我可以使用GetQueryInfo来获取内容类型.我是否需要解析才能找到编码?我将尝试下一个.
I''ve been using wininet in a client-side application in Unicode mode. Mostly, it''s working.
I put the download into a char* buffer and build out a std::string on each InternetReadFile. Since I think I''m getting a UTF8 encoding web page, I use CA2W(buffer,CP_UTF8) to convert after I''ve downloaded it all.
However, I''m wondering how I know what the charset encoding is of the downloaded file...
I understand that /if/ it is UTF8, I should convert it. But what if it isn''t UTF8? What if it is UTF16 or ISO-8859-1 or ANSI?
I can use GetQueryInfo to get the content type. Do I need to parse this to find the encoding? I''m going to try that next.
