Windows 8 - Cordova - navigator.camera.getPicture [英] Windows 8 - Cordova - navigator.camera.getPicture

问题描述

我们正在使用Cordova / Phonegap 3.1.0将我们的HTML应用程序移植到Windows 8。大多数运行良好;然而，当我们使用FILE_URI导航拍摄照片时，我们会收到最初看起来像一个blob，但只是一个字符串（我相信）。

一个示例字符串使用以下代码时可以返回：

  blob：00000000-0000-0000-0000-000000000000 
  

使用：

  navigator.camera.getPicture（success，failure，{
 quality：40，
 destinationType：Camera.DestinationType.FILE_URI，
 sourceType：Camera.PictureSourceType.CAMERA，
 allowEdit：false ，
 encodingType：Camera.EncodingType.JPEG，
 targetWidth：320，
 targetHeight：240 
}）; 
  

解决方案

目前似乎不支持这种方法： p>

http://cordova.apache.org/docs/en/3.1.0/cordova_file_file.md.html#File

所有文件数据都支持平台。在被写入文件系统之前，文本被编码为UTF-8。

支持的平台 >

文字和二进制支持：

Android

iOS

纯文字支援：

BlackBerry WebWorks（OS 5.0及更高版本）

Windows Phone 7和8

Windows 8

我正在开发一个WinJS解决方案与平台检测。如果可能，我将更新此信息。

We are in the process of porting our HTML application to Windows 8 using Cordova/Phonegap 3.1.0. Most of it runs fine; however when we take a photo using the FILE_URI navigation, we receive what initially looks like a blob, but is just a string (I believe).

An example string I get back when using the following code, could be:

blob:00000000-0000-0000-0000-000000000000

Using:

navigator.camera.getPicture(success, failure, {
    quality: 40,
    destinationType: Camera.DestinationType.FILE_URI,
    sourceType: Camera.PictureSourceType.CAMERA,
    allowEdit: false,
    encodingType: Camera.EncodingType.JPEG,
    targetWidth: 320,
    targetHeight: 240
});

解决方案

Currently this does not seem to be supported:

http://cordova.apache.org/docs/en/3.1.0/cordova_file_file.md.html#File

Text data is supported by all platforms listed below. Text is encoded as UTF-8 before being written to the filesystem. Some platforms also support binary data, which can be passed in as either an ArrayBuffer or a Blob.

Supported Platforms

Text and Binary Support:

Android

iOS

Text-only Support:

BlackBerry WebWorks (OS 5.0 and higher)

Windows Phone 7 and 8

Windows 8

I am working on a WinJS workaround with platform detection. I will update this post if it is possible.
