我正在尝试使用我编译的fcgi应用程序使用fastcgi库(http://www.fastcgi.com/)上传文件。
当我上传一个小文件(<500KB)时,上传成功。但是,当我上传大于500KB的文件时,我得到503错误(服务不可用)。我可以确认整个文件已经以1MB块的形式上传到lighttpd的临时目录。
对于我的测试,max-request-size设置为30MB,我的测试文件大小为14MB。
上传文件块后,日志显示如下:
(mod_fastcgi.c.3058) got proc: pid: 2171 socket: unix:/tmp/fcgi.sock-0 load: 1
(network_writev.c.303) write failed: Bad address 7
(mod_fastcgi.c.3098) write failed: Bad address 14
(mod_fastcgi.c.1490) released proc: pid: 2171 socket: unix:/tmp/fcgi.sock-0 load: 0
组装的上传文件大约是500KB。
有人可以为我阐明一下吗?
我的fcgi应用程序如下:
#include "fcgi_stdio.h"
#include <stdlib.h>
#include <fcntl.h>
#include <sys/types.h>
#include <sys/stat.h>
void main(void)
{
int count = 0;
while(FCGI_Accept() >= 0) {
char *contentLength = getenv("CONTENT_LENGTH");
int len;
if (contentLength != NULL) {
len = strtol(contentLength, NULL, 10);
}
else {
len = 0;
}
printf("Content-type: text/html\r\n"
"\r\n"
"<title>FastCGI Hello!</title>"
"<h1>FastCGI Hello!</h1>"
"Request number %d running on host <i>%s</i>\n",
++count, getenv("SERVER_NAME"));
printf("<br />CONTENT_LENGTH = %d <br />\r\n", len);
printf("<form enctype='multipart/form-data' method='post' action='?'><input type='text' name='text1' /><input type='file' name='file1'/><input type='submit' /></form>");
printf("<hr />");
fflush(stdout);
FCGI_FILE * fileOut = FCGI_fopen("/tmp/fcgi.out", "w");
if (fileOut) {
int done = 0;
while(done < len) {
char buffer[1024];
int i;
int packetRead;
packetRead = FCGI_fread(buffer, 1, sizeof(buffer), stdin);
if (packetRead < 0) {
break;
}
if (packetRead > 0) {
FCGI_fwrite(buffer, 1, packetRead, fileOut);
done += packetRead;
}
}
FCGI_fclose(fileOut);
}
FCGI_Finish();
}
}
提前致谢。
答案 0 :(得分:-1)
当您提供的地址位置无效时,写入错误错误地址会上升。
我不知道FCGI_fread和FCGI_fwrite,但是他们的POSIX等价物
FCGI_fread(buffer, 1, sizeof(buffer), stdin);
FCGI_fwrite(buffer, 1, packetRead, fileOut);
应该是
FCGI_fread(&buffer, 1, sizeof(buffer), stdin);
FCGI_fwrite(&buffer, 1, packetRead, fileOut);
可能会有所帮助。
第二名:
size_t FCGI_fread(void *ptr, size_t size, size_t nmemb, FCGI_FILE *fp);
size_t FCGI_fwrite(void *ptr, size_t size, size_t nmemb, FCGI_FILE *fp);
可能会更好?:
FCGI_fread(&buffer, sizeof(char), sizeof(buffer), stdin);
FCGI_fwrite(&buffer, sizeof(char), packetRead, fileOut);
