我有一个我无法解决的奇怪问题。 我使用codeiginter ajax和jquery。
我通过此域名http://localhost:8070/apps/views
拨打电话var fs = require('fs');
var electron = require('electron');
var SECRET_KEY = 'Magnemite';
var recorder;
var blobs = [];
function startRecording() {
var title = document.title;
document.title = SECRET_KEY;
electron.desktopCapturer.getSources({ types: ['window', 'screen'] }, function(error, sources) {
if (error) throw error;
for (let i = 0; i < sources.length; i++) {
let src = sources[i];
if (src.name === SECRET_KEY) {
document.title = title;
navigator.webkitGetUserMedia({
audio: false,
video: {
mandatory: {
chromeMediaSource: 'desktop',
chromeMediaSourceId: src.id,
minWidth: 800,
maxWidth: 1280,
minHeight: 600,
maxHeight: 720
}
}
}, handleStream, handleUserMediaError);
return;
}
}
});
}
function handleStream(stream) {
recorder = new MediaRecorder(stream);
blobs = [];
recorder.ondataavailable = function(event) {
blobs.push(event.data);
};
recorder.start();
}
function stopRecording() {
recorder.stop();
toArrayBuffer(new Blob(blobs, {type: 'video/webm'}), function(ab) {
var buffer = toBuffer(ab);
var file = `./videos/example.webm`;
fs.writeFile(file, buffer, function(err) {
if (err) {
console.error('Failed to save video ' + err);
} else {
console.log('Saved video: ' + file);
}
});
});
}
function handleUserMediaError(e) {
console.error('handleUserMediaError', e);
}
function toArrayBuffer(blob, cb) {
let fileReader = new FileReader();
fileReader.onload = function() {
let arrayBuffer = this.result;
cb(arrayBuffer);
};
fileReader.readAsArrayBuffer(blob);
}
function toBuffer(ab) {
let buffer = new Buffer(ab.byteLength);
let arr = new Uint8Array(ab);
for (let i = 0; i < arr.byteLength; i++) {
buffer[i] = arr[i];
}
return buffer;
}
// Record for 7 seconds and save to disk
startRecording();
setTimeout(function() { stopRecording() }, 7000);
在执行此代码之前,我在此url中创建会话:
http:// localhost / multicode / login / prueba
现在发生的事情就是当我执行我的ajax代码时 null并且当我在浏览器上执行此URL(http://localhost/multicode/login/prueba)时,我得到了我在开始时创建的会话。
答案 0 :(得分:1)
如果您将使用不同的域调用ajax,则会话将不会保留,因为会话保存在另一台服务器上。
