确保您的上传功能与此类似
function upload() {
var img = document.getElementById('image');
var imageURI = img.src;
var options = new FileUploadOptions();
options.fileKey = "file";
options.fileName = imageURI.substr(imageURI.lastIndexOf('/') + 1);
options.mimeType = "image/jpeg";
var params = new Object();
options.params = params;
options.chunkedMode = false;
var ft = new FileTransfer();
ft.upload(imageURI, "https://www.example.com/upload.php", win, fail,
options);
}
参考资料：文件上载正常，没有扩展名。例如，如果文件名是dato.jpg，当我上传时，我只能看到datoi，如果你不介意的话，我可以看到你的完整源代码吗？这就是我问题中粘贴的内容。我现在工作的问题是由于互联网连接。我现在面对的正是我上面写的。文件扩展名无法保存
