[英]How to retrieve the download Url after uploading image to Firebase storage, so that I can save it to Firebase database?
下面的代码成功将图像上传到 Firebase 存储,但我想检索该确切图像的 downloadURL 并将其存储在“this.pichaMtumiaji”中,然后将其保存在 Firebase 数据库中。 我正在使用离子 3!
uploadPhoto(): void {
this.myPhotosRef.child(this.generateUUID()).child('myPhoto.png')
.putString(this.myPhoto, 'base64', { contentType: 'image/png' })
.then((savedPicture) => {
this.pichaMtumiaji = savedPicture.downloadURL().absoluteString;
});
}
generateUUID(): any {
var d = new Date().getTime();
var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx'.replace(/[xy]/g, function (c) {
var r = (d + Math.random() * 16) % 16 | 0;
d = Math.floor(d / 16);
return (c == 'x' ? r : (r & 0x3 | 0x8)).toString(16);
});
return uuid;
}
基于Firebase 文档中关于上传文件的示例:
var ref = this.myPhotosRef.child(this.generateUUID()).child('myPhoto.png');
ref
.putString(this.myPhoto, 'base64', { contentType: 'image/png' })
.then((savedPicture) => {
// Upload completed successfully, now we can get the download URL
ref.getDownloadURL().then(function(downloadURL) {
console.log('File available at', downloadURL);
this.pichaMtumiaji = savedPicture.downloadURL().absoluteString;
});
});
