just fail hard and fast
hi every one , so sorry for any interrupt, can anyone tell how to catch ip address of client connected to webserver in AP and Station mode ,? is following code correct
ESP8266WebServer server(80);
void handleRoot() {
Serial.print("this request if from=");Serial.println(server.client().remoteIP());
server.send(200, "text/html", "<h1>You are connected to slave node</h1>");
}
@everslick and @me-no-dev, why do we have to send 'Content-Disposition: inline; filename='...' with every file that we serve? This is an overhead TMOH and also expose the actual file location in the file system. Sorry I was not following the full discussion on it, but as far as I can read this is not HTTP standard and has some security risks: stackoverflow
@mkeyno
if(server.client().localIP() != WiFi. localIP()){ server.send(200, "text/html", "<h1>You are connected to my AP</h1>"); }
This message was deleted
best to check against STA IP
localIP is the IP that the client connected to
so its
server.client().remoteIP()
and then cycle through all subnet IPs until i find one which is authorized
but what if two machine intend to talk each other in pre set secure line
I can set ip address of sensor module in my actuator module , but as you say it is totally leak
do you have any example of that
From RFC6266 section 4.2:
On the other hand, if it matches "inline" (case-insensitively), this implies default processing. Therefore, the disposition type "inline" is only useful when it is augmented with additional parameters, such as the filename (see below).
To my understanding, this code is more to the point (not tested):
if(download) {
// set filename and force download
int filenameStart = path.lastIndexOf('/') + 1;
char buf[26+path.length()-filenameStart];
char* filename = (char*)path.c_str() + filenameStart;
snprintf(buf, sizeof (buf), "attachment; filename='%s'", filename);
addHeader("Content-Disposition", buf);
}
