Description: I try replace http body data in http response, the script is clone base on HTTP_DATA_FIND_REMOVE_REPLACE_DEMO
the script as:
when HTTP_RESPONSE{
--HTTP:collect command can be used in both HTTP_REQUEST
--and HTTP_RESPONSE events
--size is optional, otherwise, it will collect up to the full length
--or when 1.25M is reached
t={}
t["size"] = 100;
HTTP:collect(t)
}
when HTTP_DATA_RESPONSE{
--check the size of the content
t={};
t["operation"]="size";
sz=HTTP:payload(t);
debug("content size: %s\n", sz);
--replace a string or a regular expression in the buffered data by a new string
--offset, size and scope are optional, if scope is missing, "all" is assumed
t={};
t["operation"]="replace";
t["offset"] = 0;
t["size"] = sz;
t["scope"] = "all";-- or "first"
t["data"] = "http://cn.studyinchina.edu.cn";
t["new_data"] = "http://cn.proxy.studyinchina.edu.cn";
ret = HTTP:payload(t);
if ret then
debug("replaced %d occurences\n", ret);
else
debug("not found\n");
end
}
I also try
t["data"] = "http://cn.studyinchina.edu.cn/cscse2020/lxjh/lxyk/402274/index.html";
t["new_data"] = "http://cn.proxy.studyinchina.edu.cn/cscse2020/lxjh/lxyk/402274/index.html";
but all two script can not trigger the replace action.
the website is: www.cscse.edu.cn
Is there any wrong with my script ?
