我的移动应用程序中有两个目标。
a)用手机相机拍照并将其上传到服务器
b)从手机图库中选择图片并将其上传到服务器
我一直在使用Phonegap并指出“a”效果很好。也是“b”。
问题:似乎每次上传都失败了。无论我从点“a”还是点“b”开始。或随机组合。
结果:
成功
2.失败了
3.成功
4.失败了
4.等。
这是我的点“a”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
}
);
}
和点“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。
这是Eclipse日志:

可能有什么不对?任何建议表示赞赏。

这对getPicture函数来说不是问题。
我找到了非常简单的解决方案。
在我看来,cordova插件的FileTransfer()不会将有关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
我认为虚假上传将让服务器知道文件传输已经结束。
因为,Content-Length为0。

我在phonegap 2.9.0上面临同样的问题,在做了很多失败的试验来解决问题之后,我做了以下几点 - 我创建了一个新的phonegap 3.5.0项目 - 我从CLI构建了android平台 - 我将www文件夹复制到新项目根文件夹 - 我使用CLI添加了所有需要的插件 - 我在图标和启动画面的顶级config.xml文件中进行了必要的更改,因为文件构造不同 - 我运行了项目,现在没问题了。
