在C中使用FastCGI的HMTL5/UTF8(fcgi_stdio.h) [英] HMTL5 / UTF8 using FastCGI in C (fcgi_stdio.h)
问题描述
这个例子对我来说很好:
This example works fine for me:
#include "fcgi_stdio.h"
int main(void) {
while(FCGI_Accept() >= 0) {
//Standard FastCGI Example Web-page
printf("Content-type: text/html\r\n"
"\r\n"
"<title>FactCGI Example</title>"
"<h1>Example Website</h1>"
"Some text...\r\n");
FCGI_Finish();
}
return 0;
}
但是因为我的网页上需要UTF8字符，所以我认为我应该使用html5格式化网页.这是我的骨架，可以将其作为独立文件呈现:
But since I need UTF8 chars on my web-page, I thought I'd format the web page using html5. This was my skeleton which renders ok as a stand-alone file:
<!DOCTYPE html>
<html>
<head>
<title>FactCGI Example</title>
</head>
<body>
<h1>Example Website</h1>
<p>Some text...</p>
</body>
</html>
但是按如下所示将其折叠到fcgi脚本中时，在脚本加载时出现内部服务器错误".
But when folded this into the fcgi script as follows, I get an 'Internal Server Error' on script load.
#include "fcgi_stdio.h"
int main(void) {
while(FCGI_Accept() >= 0) {
//Using html5 for the web-page
printf("<!DOCTYPE html>\r\n"
"<html>\r\n"
"\r\n"
"<head>\r\n"
"<title>FactCGI Example</title>\r\n"
"</head>\r\n"
"\r\n"
"<body>\r\n"
"<h1>Example Website</h1>\r\n"
"<p>Some text...</p>\r\n"
"</body>\r\n"
"\r\n"
"</html>\r\n");
FCGI_Finish();
}
return 0;
}
Fedora 23，httpd 2.8.18，Firefox 43.0.3，gcc 5.3.1-2
Fedora 23, httpd 2.8.18, Firefox 43.0.3, gcc 5.3.1-2
Google搜索表示所有fcgi，网页均以内容类型:text/html"开头.
Googling indicates all fcgi, web pages start with "Content-type: text/html".
我犯了一些愚蠢的错误，还是fcgi只是不支持html5?
Have I made some silly mistake or does fcgi just not support html5?
还有其他方法可以使用fcgi启用UTF8支持吗?
Is there some other way to enable UTF8 support using fcgi?
推荐答案
该错误很可能是由于输出中没有Content-type HTTP标头而引起的.另外，如果要使用UTF-8，则应在Content-type标头中将UTF-8指定为字符集.但是，您无需使用HTML5即可在网页中使用UTF-8.该编码也可以与较早的HTML版本一起使用.
The error is likely caused because you don't have the Content-type HTTP header in your output. Also, if you want to use UTF-8, then you should specify UTF-8 as the charset in the Content-type header. But you don't need to use HTML5 to use UTF-8 in your web page; the encoding can be used with older HTML versions as well.
这是添加了Content-type标头和UTF-8参数的代码.
Here's your code with the Content-type header and UTF-8 parameter added.
#include "fcgi_stdio.h"
int main(void) {
while(FCGI_Accept() >= 0) {
//Using html5 for the web-page
printf("Content-type: text/html charset=utf-8\r\n"
"\r\n"
"<!DOCTYPE html>\r\n"
"<html>\r\n"
"\r\n"
"<head>\r\n"
"<title>FactCGI Example</title>\r\n"
"</head>\r\n"
"\r\n"
"<body>\r\n"
"<h1>Example Website</h1>\r\n"
"<p>Some text...</p>\r\n"
"</body>\r\n"
"\r\n"
"</html>\r\n");
FCGI_Finish();
}
return 0;
}
