Phonegap上传的camera.getPicture问题

Question

我在我的移动应用程序中有两个目标。

a)用手机摄像头拍照上传到服务器

b)从手机的图库中挑选图片并上传到服务器

我一直在使用Phonegap和点"a“，效果很好。也叫"b“。

问题:似乎每秒上传都会失败。不管我是从"a“点还是从"b”点开始。或者随机组合。

结果：

1. success
2. failed
3. success
4. failed
5. etc.

这是我对“a”点的代码：

function getImageCamera() {
    navigator.camera.getPicture(uploadPhotoCamera, function(message) {
    },{
        targetWidth: 1200,
        targetHeight: 900, 
        quality: 75, 
        destinationType: navigator.camera.DestinationType.FILE_URI,
        sourceType: navigator.camera.PictureSourceType.CAMERA
    }
    );
}

对于点"b"：

function getImageGallery() {
    navigator.camera.getPicture(uploadPhotoGallery, function(message) {
    },{
        targetWidth: 1200,
        targetHeight: 900, 
        quality: 75, 
        destinationType: navigator.camera.DestinationType.FILE_URI,
        sourceType: navigator.camera.PictureSourceType.SAVEDPHOTOALBUM
    }
    );
}

函数uploadPhotoCamera和uploadPhotoGallery是相同的。

以下是Eclipse日志：

会出什么问题呢？如有任何建议，欢迎光临。

Answer 1

这不是getPicture函数的问题。

我已经找到了非常简单的解决方案。

在我看来，cordova插件的FileTransfer()不会将文件传输结束的数据发送到服务器。

因此，服务器无法识别每个文件的边界，并出现问题。

var url = "http://www.upload-server-domain";
var imgFileURI = '/filepath/test.jpg';
var ft = new FileTransfer();

ft.upload('', encodeURI(url), null, null, null);   // SOLUTION : fake upload                
ft.upload(imgFileURI, encodeURI(url), fnSuccessCallback, fnErrorCallback, options); // real upload

我认为假上传会让服务器知道文件传输结束了。

因为，Content-Length是0。

我在PhoneGap2.9.0上遇到了同样的问题，在做了许多失败的试验来解决这个问题后，我做了以下事情--我创建了一个新的PhoneGap3.5.0项目--我从命令行界面构建了安卓平台--我复制了www文件夹到新的项目根文件夹--我使用命令行界面添加了所有需要的插件--我在顶层的config.xml文件中对图标和闪屏做了必要的修改，因为文件结构不同--我运行了这个项目，现在一切都好了。
