使用FileTransfer上传图像时出现问题 [英] Trouble to upload images with FileTransfer
问题描述
我正在尝试在我的应用程序中添加一个功能,允许用户使用相机或智能手机拍照,将其上传为个人照片。
<我已经从另一个项目中选择了这个功能,这个项目效果很好但不是我的,而是我的同事之一(他离开了)。
我不知道知道为什么,因为我使用了完全相同的功能,但上传的图像如下所示:
它将随机开始破坏文件,通常在第一季度。有一次,它有效,但我无法理解为什么。
takePhoto(value){
const选项:CameraOptions = {
quality:75,
destinationType:this.camera.DestinationType.DATA_URL,
encodingType:this.camera.EncodingType.JPEG,
mediaType:this。 camera.MediaType.PICTURE,
correctOrientation:true,
allowEdit:true,
targetWidth:300,
targetHeight:300,
sourceType:value
}
this.camera.getPicture(options).then((imageData)=> {
// imageData是base64编码的字符串或文件URI
//如果它是base64:
让base64Image ='data:image / jpeg; base64,'+ imageData;
console.log(base64Image)
// $( #imgProfil)。attr(src,base64Image);
const fileTransfer:FileTransferObject = this.transfer.create();
this._zone.run(( )=> {
this.avatar_path = base64Image;
});
var targetPath = base64Image;
var options = {
fileKey:avatar,
fileName:this.user._id +.jpg,
chunkedMode:false,
mimeType: image / jpeg,
标题:{
//连接:关闭
}
};
fileTransfer.upload(targetPath,http://XX.XXX.XXX.XX:90 / add / photoandroid /+ this.user._id,options).then((data)= > {
this.storage.set('photoProfilData',base64Image);
this.events.publish('photoProfil');
},(err)=> ; {
})
},(错误)=> {
this.presentToasti(err);
});
}
任何想法为什么它是这样做?
哦,忘了提及:使用iOS版本的应用程序,上传图像效果很好所以我认为问题不是来自服务器属性。 iOS应用程序使用自己的函数来检索服务器上的图像。
这是服务器端:
exports.addphotoandroid = function(req,res){
var ObjectID = require('mongodb')。ObjectID;
var fstream;
var monid = req.params.id;
req.pipe(req.busboy);
req.busboy.on('file',function(fieldname,file,filename){
console.log(Uploading:+ monid + .jpg);
//将上传图像的路径
fstream = fs.createWriteStream(/ var / sammy / public / upload / photoprofil /+ monid +.jpg);
file.pipe(fstream);
fstream.on('close',function(){
console.log(Upload Finished of+ monid +.jpg);
response = {succces:photobienupupée};
});
});
};
通过尝试Salman Ullah回答:

尝试使用imageData而不是targetPath。
像这样:
fileTransfer.upload(imageData,http://XX.XXX.XXX.XX:90 / add / photoandroid /+
this.user。 _id,options).then((data)=> {
I’m trying to add a function to my application which allow the user to take a picture with his camera or from his smartphone to upload it as a profil picture.
I’ve picked this function from another project which is working great but isn’t from me but one of my colleague (he left).
I don’t know why since I’ve used the exact same function but the image uploaded look like this :
It will randomly start to corrupt the file, generally in the first quarter. One time, it worked but I can’t figure why.
takePhoto(value){
const options: CameraOptions = {
quality: 75,
destinationType: this.camera.DestinationType.DATA_URL,
encodingType: this.camera.EncodingType.JPEG,
mediaType: this.camera.MediaType.PICTURE,
correctOrientation : true,
allowEdit:true,
targetWidth: 300,
targetHeight: 300,
sourceType : value
}
this.camera.getPicture(options).then((imageData) => {
// imageData is either a base64 encoded string or a file URI
// If it's base64:
let base64Image = 'data:image/jpeg;base64,' + imageData;
console.log(base64Image)
//$("#imgProfil").attr("src",base64Image);
const fileTransfer: FileTransferObject = this.transfer.create();
this._zone.run(() => {
this.avatar_path = base64Image;
});
var targetPath = base64Image;
var options = {
fileKey: "avatar",
fileName: this.user._id + ".jpg",
chunkedMode: false,
mimeType: "image/jpeg",
headers: {
//Connection: "close"
}
};
fileTransfer.upload(targetPath,"http://XX.XXX.XXX.XX:90/add/photoandroid/" + this.user._id, options) .then((data) => {
this.storage.set('photoProfilData',base64Image);
this.events.publish('photoProfil');
}, (err) => {
})
}, (err) => {
this.presentToasti(err);
});
}
Any idea why it is doing this ? Oh, forgot to mention : with the iOS version of the app, uploading images is working great so I don't think the problem comes from the server properties. The iOS app uses its own function to retrieve the image on the server.
And here is server side :
exports.addphotoandroid = function(req, res){
var ObjectID = require('mongodb').ObjectID;
var fstream;
var monid = req.params.id;
req.pipe(req.busboy);
req.busboy.on('file', function (fieldname, file, filename) {
console.log("Uploading: " + monid + ".jpg");
//Path where image will be uploaded
fstream = fs.createWriteStream("/var/sammy/public/upload/photoprofil/" + monid + ".jpg");
file.pipe(fstream);
fstream.on('close', function () {
console.log("Upload Finished of " + monid + ".jpg");
response = {"succces" : "photo bien uploadée "};
});
});
};
By trying with Salman Ullah answer :

This is the error I get from the server.
Try senging imageData instead of targetPath.
Like this:
fileTransfer.upload(imageData ,"http://XX.XXX.XXX.XX:90/add/photoandroid/" +
this.user._id, options) .then((data) => {
