GWAN:如何读取Cookie [英] GWAN : How to read cookies
问题描述
我正在尝试读取cookie,但是下面的脚本返回一个空字符串.
http_t *http = (http_t*)get_env(argv, HTTP_HEADERS);
xbuf_t *read_buf = (xbuf_t*)get_env(argv, READ_XBUF);
char *p = read_buf->ptr;
char *cookies = http->h_cookies ? p + http->h_cookies : 0;
xbuf_xcat(reply, "<HR>COOKIES [%s]<br>", cookies);
我之前使用以下网址设置了Cookie:http_header(可以在chrome的控制台中看到)
那我该如何阅读cookie?
谢谢您的回答.
我正在使用GWAN 4.11.20
尽管添加了新值,但 v4.11仍未同步gwan/includes
头而发布.
结果,get_env()
在G-WAN脚本中使用的某些值与G-WAN使用的值不匹配.
一种解决方案是更正gwan.h
标头中的这些值.访问Cookie的另一种简单方法是使用 READ_XBUF 到达读取缓冲区(请参见连接处理程序"标签)然后使用类似于G-WAN cookies.c 示例的代码查找cookie.>
Paulo,一个存在相同问题的G-WAN用户,向我们发送了以下源代码:
int getSessionID(int argc, char *argv[]) {
http_t *http = (http_t*)get_env(argv, HTTP_HEADERS);
xbuf_t *read_buf = (xbuf_t*)get_env(argv, READ_XBUF);
char *p = read_buf->ptr;
int sessionID = 0;
if (http) {
sessionID = http->session_id;
fprintf(stderr, "Get SessionID %d\n", sessionID);
}
fprintf(stderr, "Get SessionID Cookie %d\n", http->h_cookies);
if (p && *p && http->h_cookies) {
char *cookies = p + http->h_cookies;
fprintf(stderr, "Get SessionID Cookie %s\n", cookies);
// The sessionID is on the Cookie
sessionID = atoi(cookies + 5);
}
if (!sessionID) {
// The sessionID is not on the Cookie so send the server Session_ID
sessionID = (int)get_env(argv, SESSION_ID);
}
if (!sessionID) {
// Oops! I have no session from the Server. use the IP Address and a timestamp
sessionID = (int)get_env(argv, REMOTE_BIN_ADDR) + getms();
}
return sessionID;
}
这将使您入门.
I'm trying to read cookies but the script below returns an empty string.
http_t *http = (http_t*)get_env(argv, HTTP_HEADERS);
xbuf_t *read_buf = (xbuf_t*)get_env(argv, READ_XBUF);
char *p = read_buf->ptr;
char *cookies = http->h_cookies ? p + http->h_cookies : 0;
xbuf_xcat(reply, "<HR>COOKIES [%s]<br>", cookies);
I have set a cookie previously using : http_header (which I can see in chrome's console)
So how can I read cookies?
Thank you for your answer.
I'm using GWAN 4.11.20
v4.11 was issued without synchronizing the gwan/includes
headers despite new values being added.
As a result, some of the values used by get_env()
in G-WAN scripts do not match the values used by G-WAN.
A solution would be to correct these values in the gwan.h
header. Another simpler way to access cookies is to reach the read buffer using READ_XBUF (see the "connection handler" tab) and then look for the cookies using code similar to the G-WAN cookies.c example.
Paulo, a G-WAN user having the same problem has sent us the following source code:
int getSessionID(int argc, char *argv[]) {
http_t *http = (http_t*)get_env(argv, HTTP_HEADERS);
xbuf_t *read_buf = (xbuf_t*)get_env(argv, READ_XBUF);
char *p = read_buf->ptr;
int sessionID = 0;
if (http) {
sessionID = http->session_id;
fprintf(stderr, "Get SessionID %d\n", sessionID);
}
fprintf(stderr, "Get SessionID Cookie %d\n", http->h_cookies);
if (p && *p && http->h_cookies) {
char *cookies = p + http->h_cookies;
fprintf(stderr, "Get SessionID Cookie %s\n", cookies);
// The sessionID is on the Cookie
sessionID = atoi(cookies + 5);
}
if (!sessionID) {
// The sessionID is not on the Cookie so send the server Session_ID
sessionID = (int)get_env(argv, SESSION_ID);
}
if (!sessionID) {
// Oops! I have no session from the Server. use the IP Address and a timestamp
sessionID = (int)get_env(argv, REMOTE_BIN_ADDR) + getms();
}
return sessionID;
}
This will get your started.
