Embedded YouTube video doesn't work on local server

问题 I saw many questions like this asked on StackOverflow, but none of them had a working answer. My problem is that I can't embed a YouTube video, because a "This video is not available." comes up: Here's what I know and have tried so far: This error doesn't come up on all videos. From what I've noticed, it's mostly not working on popular music videos. Embedding these YouTube videos doesn't work in a local HTML file ( file:///C:/path/to/file.html ) nor when the embedded video is on my local

问题 I created a local HTML file in my iOS app written in swift. The HTML file is loaded into a WKWebView as follows: let url = Bundle(identifier: myIdentifier).url(forResource: "localHtmlFile", withExtension: "html") let htmlFormatString = try String(contentsOf: url) loadHTMLString(string: htmlFormatString, baseURL: nil) The HTML page contains an iframe which I expect to load an external page: <div>Test</div> <iframe src="https://www.somepage.com"></iframe> The local HTML file is loaded

一、简介 1、前端开发最核心技术 我们知道，用所谓的网页三剑客已经不能满足需求了，那前端开发究竟要学习什么技术呢？网页最主要由3部分组成：结构、表现和行为。网页现在新的标准是W3C，目前模式是HTML、CSS和JavaScript。 （1）HTML是什么？ HTML，全称“Hyper Text Markup Language（超文本标记语言）”，简单来说，网页就是用HTML语言制作的。HTML是一门描述性语言，是一门非常容易入门的语言。 （2）CSS CSS，全称“（层叠样式表）”。以后我们在别的地方看到“层叠样式表”、“CSS样式”，指的就是CSS。 （3）JavaScript JavaScript是一门脚本语言。 、前端开发其他技术 前端技术最核心的是HTML、CSS和JavaScript，但是对于一个真正的前端工程师来说，哪怕你精通这三个，你也不能称为一个真正的“前端工程师”。因为前端技术除了HTML、CSS和JavaScript这三种，还需要学习Ajax、SEO等。 （1）Ajax Ajax，即“Asynchronous Javascript And XML（异步JavaScript和XML）”，是指一种创建交互式网页应用的网页开发技术。 通过在后台与服务器进行少量数据交换，Ajax可以使网页实现异步更新。这意味着可以在不重新加载整个网页的情况下，对网页的某部分进行更新

前端大文件上传解决方案

最近遇见一个需要上传百兆大文件的需求，调研了七牛和腾讯云的切片分段上传功能，因此在此整理前端大文件上传相关功能的实现。 在某些业务中，大文件上传是一个比较重要的交互场景，如上传入库比较大的Excel表格数据、上传影音文件等。如果文件体积比较大，或者网络条件不好时，上传的时间会比较长（要传输更多的报文，丢包重传的概率也更大），用户不能刷新页面，只能耐心等待请求完成。 下面从文件上传方式入手，整理大文件上传的思路，并给出了相关实例代码，由于PHP内置了比较方便的文件拆分和拼接方法，因此服务端代码使用PHP进行示例编写。 本文相关示例代码位于github上，主要参考 聊聊大文件上传 大文件切割上传 文件上传的几种方式 首先我们来看看文件上传的几种方式。 普通表单上传 使用PHP来展示常规的表单上传是一个不错的选择。首先构建文件上传的表单，并指定表单的提交内容类型为enctype="multipart/form-data"，表明表单需要上传二进制数据。 然后编写index.php上传文件接收代码，使用move_uploaded_file方法即可(php大法好…) form 表单上传大文件时，很容易遇见服务器超时的问题。通过xhr，前端也可以进行异步上传文件的操作，一般由两个思路。 文件编码上传 第一个思路是将文件进行编码，然后在服务端进行解码，之前写过一篇在前端实现图片压缩上传的博客
