senchatouch从服务器下载文件-senchatouchtodownloadfilesfromserver

Sencha Touch is a client side framework with no APIs into a filesystem. That said, you can't download files to the app itself. Since ST is essentially a website, you could also utilize code on the server side to handle something like that though.

Sencha Touch是一个客户端框架，没有API进入文件系统。也就是说，您无法将文件下载到应用程序本身。由于ST本质上是一个网站，你也可以利用服务器端的代码处理类似的东西。

One thing to note is that if you are packaging your app in a native wrapper like PhoneGap, then yes, you can utilize their APIs to access the native file system. I'm using a PhoneGap plugin called pixFileDownload to do just that.

需要注意的一点是，如果您将应用程序打包在PhoneGap等本机包装中，那么可以使用它们的API来访问本机文件系统。我正在使用名为pixFileDownload的PhoneGap插件来做到这一点。

Not true.

不对。

If you have the PDF in the form of a url, you can simply create an iframe within a Sencha container and set the src to the url.

如果你有一个url形式的PDF，你只需在Sencha容器中创建一个iframe并将src设置为url。

If you do not have an url, but rather some sort of access to the binary PDF file you may want to look into the Blob api. You can take a look at https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications#Example.3A_Using_object_URLs_to_display_images to get an idea of where to start.

如果您没有网址，而是某种对二进制PDF文件的访问权限，您可能需要查看Blob api。您可以查看https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications#Example.3A_Using_object_URLs_to_display_images，了解从哪里开始。

How to upload a file? Use XMLHttpRequest with the PUT verb and post your file. Of course you need somewhere to post it to. As sencha touch is client side, you need something installed on the server you want to upload to.

如何上传文件？将XMLHttpRequest与PUT动词一起使用并发布您的文件。当然你需要在某个地方发布它。由于sencha touch是客户端，因此您需要在要上载的服务器上安装某些内容。

Happy coding :-)
