我如何从PhoneGap camera.getPicture获取一个File对象？ [英] How would I get a File object from PhoneGap camera.getPicture?

问题描述

这可能很简单，并由PhoneGap的相机插件，文件插件或文件传输插件中的一些功能组合覆盖。我理解用户可以选择一个文件：

This is probably simple and covered by some combination of functions in PhoneGap's "Camera" plugin, "File" plugin, or "File-Transfer" plugin. I understand the user can select a file with:

navigator.camera.getPicture(function (fileURI) {

    // *** need help here ***

}, function ()
    // handle errors
}, {
    destinationType: window.Camera.DestinationType.FILE_URI,
    sourceType: window.Camera.PictureSourceType.PHOTOLIBRARY,
    mediaType: window.Camera.MediaType.ALLMEDIA
});

我也可以改成 destinationType：window.Camera.DestinationType.DATA_URL 如果这有区别。

I can also change to destinationType: window.Camera.DestinationType.DATA_URL if that makes a difference.

我的目标在成功处理程序是获取一个File对象（ https://developer.mozilla.org/en-US/docs/Web/API/File ）。

My goal in the success handler is to get a File object (https://developer.mozilla.org/en-US/docs/Web/API/File).

推荐答案

这样应该可以做。

navigator.camera.getPicture(function (fileURI) {

    window.resolveLocalFileSystemURI(fileURI, 
        function( fileEntry){
            alert("got image file entry: " + fileEntry.fullPath);
        },
        function(){//error}
    );

}, function (){
// handle errors
}, {
    destinationType: window.Camera.DestinationType.FILE_URI,
    sourceType: window.Camera.PictureSourceType.PHOTOLIBRARY,
    mediaType: window.Camera.MediaType.ALLMEDIA
});
