When I use localhost local access can be used to record the screen features (for example: localhost/target/index. The HTML), but when I access by IP address (for example: 172.16.2.222/target/index. The HTML) would be an error: getDisplayMedia 'of undefined, someone met you
The code below:

 
//start recording 
The function startCapture () {
Return the navigator. MediaDevices. GetDisplayMedia (options). Then (stream=& gt; {
Tracks=stream. GetTracks (); 
If (tracks [0]. Label. IndexOf (" screen ")===1) {
Layer. Confirm (' you refused to record screen request, will be logged out! '{
BTN: [' know ']//button 
, cancel: function (index, layero) {
LocalStorage. The clear (); 
SessionStorage. The clear (); 
Location. A href="https://bbs.csdn.net/topics/login.html"; 
}
{}, function (index) 
layer.close(index); 
LocalStorage. The clear (); 
SessionStorage. The clear (); 
Location. A href="https://bbs.csdn.net/topics/login.html"; 
}); 
Return 
}
RecordingScreen ();//start the time 
//JTSB ();//to monitor mouse action 
Let the mediaRecorder=new mediaRecorder (stream); 
The mediaRecorder. Ondataavailable=function (blob) {
FlagTime +=1; 
Var oReq=new XMLHttpRequest (); 
OReq. Open (" POST ", huijuOptions BasicsBaseUrl + '/capture/newFile, true); 
Var fd=new FormData (); 
Fd. Append (" datas ", blob. Data); 
Fd. Append (" fileName ", captureName); 
OReq. Send (fd); 
}; 
The mediaRecorder. Start (1000) 
}). The catch (error=& gt; {
If (error. Name==="NotAllowedError") {
Layer. Confirm (' you do not choose full screen recording, will log out! '{

Use the inside of the IP mediaDevices object does not exist

CodePudding user response:

refer to the second floor jio can reply:

mediaDevices object using IP inside there is no

You say is what meaning, I didn't quite understand

CodePudding user response:

When using the IP address in the navigator mediaDevices object does not exist

CodePudding user response:

references 4 floor jio can reply:

when using IP address in the navigator mediaDevices object doesn't exist

Thanks, solved, the reason is the navigator. MediaDevices support only localhost, HTTPS, file://these three kinds of environment, need to configure the HTTP
