我尝试在新的 BlackBerry 10 设备 (Z10) 中运行 PhoneGap 应用程序，但遇到了问题。基本上，我拍了一张照片，想通过 FileTransfer 将其上传到我的服务器，但 FileTransfer 失败并出现 FileTransferError.FILE_NOT_FOUND_ERR。
然后我尝试使用 window.resolveLocalFileSystemURI 方法，现在得到一个 FileError.NOT_FOUND_ERR。我假设这两个错误是相关的。
我传递给这两个文件的 fileURI 是我从 navigator.camera.getPicture 成功回调中返回的 fileURI，看起来像:
file:///accounts/1000/shared/camera/IMG_00000037.jpg
我从phonegap 2.5.0 下载中获取了示例黑莓应用程序，并稍微修改了index.html 以重现该问题，我将在下面介绍该问题:

每当我运行应用程序并尝试拍照时，我都会得到:
Unable to resolve local file system URI...
为什么 FileTransfer 或 window.resolveLocalFileSystemURI 都找不到从 navigator.camera.getPicture 返回的文件？我有phonegap 示例中的标准config.xml，其中包含所有必需的功能和权限(至少据我所知)
下面是我的 config.xml:

重现问题的步骤:
- 关注this指南(使用 BlackBerry 10(QNX) 步骤)
- 将给定的 index.html 文件替换为我提供的文件
- 将给定的 config.xml 文件替换为我提供的文件(更改应该很小)
- 在 BB10 设备上调试(我使用的是 Z10)
- 点击“捕获照片”按钮，如果您连接了远程 Web 检查器，您应该会看到错误
最佳答案
您需要同时执行 blackberry.io.sandbox = false; 并删除 file://协议(protocol)，至少根据我从文件系统访问文件的经验。另外，您不应该直接访问共享路径。使用 blackberry.io.sharedFolder 属性，如本页示例所示:https://developer.blackberry.com/html5/apis/blackberry.io.html
您的文件系统路径应为 blackberry.io.sharedFolder + 'camera/IMG_00000037.jpg'
BB10 的安全沙箱设计意味着每个应用程序都有自己的共享文件系统区域的文件路径。
关于cordova - BlackBerry 10、相机和 FILE_NOT_FOUND_ERR，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15751619/
