如何将照片推送/上传到谷歌(Firebase)存储

Question

本质上，我的问题是我似乎甚至无法将照片上传到我的Firebase项目。我能够将用户信息推送到实时数据库，并且我还成功地集成了Firebase身份验证，我将其与Flask会话一起使用，以保持用户登录。似乎为了保存文件/照片，您需要使用Firebase存储，但我不知道如何使用。

用户能够点击并"；上传文件"；按钮，现在我已经将图像保存(在用户上传后(到与我的fidd.py文件相同目录的文件夹中。

以下所有代码都在我的Fiddl.py文件中。

以下是我的Firebase初始化：
注意，storageRef是我尝试过的，但存储中没有ref()，所以我会出错。此外，我有storage，因为我相信它引用了我的项目存储。

#initialize database
firebase = pyrebase.initialize_app(json.load(open('firebase/firebaseConfig.json')))
auth = firebase.auth()
db = firebase.database()                                    
#storageRef = firebase.storage.ref()                           #Points to the root reference
app.secret_key = os.urandom(24)                                #secret key:track if user is logged in
storage = firebase.storage("gs://fiddl-dev.appspot.com")      

以下是我用来将用户上传的图像存储在本地文件夹/FIDDL/Photo test中的配置。为了方便你，我缩短了路名旁注为了安全起见，我希望稍后将这些配置添加到自己的文件中，但仍然不能100%确定它们应该如何工作。除此之外，我还有一条让用户从设备上传照片的路线。

#temp image upload location
#TODO: put these in a private config file
app.config["IMAGE_UPLOAD"] = "/FIDDL//photosTest"
app.config["ALLOWED_IMAGE_EXTENSIONS"] = ["PNG", "JPG", "JPEG"]
app.config["MAX_IMAGE_FILESIZE"] = 1.5 * 1024 * 1024    #1,572,864 Bytes or 1572.864 KB
# Upload Image
@app.route('/upload-image', methods=["GET", "POST"])
def upload_image():
try:
print(session['usr'])                   #this is equal to logged in users id token->  user['idToken']
app.logger.info("A user is already logged in")
#TODO: add a logout button, make sure to delete session for use on logout
# Alert Messages
noFileName = 'Image must have a file name.'
badFileSize = 'Image file size is too large.'
badFileName = 'That image extension or file name is not allowed'
dataAdded = 'User photos added to realtime database'
if request.method == "POST":
if request.files:
image = request.files["image"]                          #works the same as user input emal in register, get the image file
print(image)
#Grab the file size
image.seek(0, os.SEEK_END)
file_size = image.tell()
app.logger.info("Image File Size: ")
app.logger.info(file_size)
#Check the image file size
if not allowed_image_filesize(file_size):
#TODO: alert user on screen of the issue
app.logger.info(badFileSize)
return redirect(request.url)

#Check for file name
if image.filename == "":
app.logger.info(noFileName)
return redirect(request.url)

#Check if image has correct type
if not allow_image(image.filename):
app.logger.info(badFileName)
return redirect(request.url)
else:
filename = secure_filename(image.filename)          #create new secure file name
app.logger.info(filename)
print(auth.current_user)
#Add data to realtime database
#TODO: figure out how to store photos in firebase


#Update progress
app.logger.info(dataAdded)


#image.save(os.path.join(app.config["IMAGE_UPLOAD"], filename))  #save images to /photosTest for testing
#print("image saved")

return redirect(request.url)
except KeyError:
app.logger.info("No user logged in, redirect to login")
return redirect(url_for('login'))

return render_template("upload_image.html")

以下是Firebase/开发/存储/规则的规则。我正在使用Firebase身份验证，但仍然收到错误：

"code": 403,
"message": "Permission denied. Could not perform this operation"
}

规则：

rules_version = '2';
// Grants a user access to a node matching their user ID
service firebase.storage {
match /b/fiddl-dev.appspot.com/o {
// Files look like: "user/<UID>/path/to/file.txt"
match /user/{userId}/{allPaths=**} {
allow write: if request.auth != null;
allow read: if true; 
}
}
}

我知道这里真的没有什么问题需要解决，但任何朝着正确方向的点都是超级棒的！谢谢

TLDR答案，包括一些小文件检查，是我出现问题的部分原因。如果需要的话，上面会有更多的细节。

将图像/文件上传到Google Firebase存储：

firebase = pyrebase.initialize_app(json.load(open('firebase/firebaseConfig.json')))
storage = firebase.storage("gs://fiddl-dev.appspot.com")
app.config["IMAGE_UPLOAD"] = "/FIDDL//photosTest"
app.config["ALLOWED_IMAGE_EXTENSIONS"] = ["PNG", "JPG", "JPEG"]
app.config["MAX_IMAGE_FILESIZE"] = 1.5 * 1024 * 1024    #1,572,864 Bytes or 1572.864 KB
# Upload Image
@app.route('/upload-image', methods=["GET", "POST"])
def upload_image():
try:
if request.method == "POST":
if request.files:
image = request.files["image"]                          
#Grab the file size
image.seek(0, os.SEEK_END) # Using seek here requires another later
file_size = image.tell()
#Check the image file size
if not allowed_image_filesize(file_size):
return redirect(request.url)

#Check for file name
if image.filename == "":
return redirect(request.url)

#Check if image has correct type
if not allow_image(image.filename):
return redirect(request.url)
else:
filename = secure_filename(image.filename)  #create new secure file name        
image.seek(0)
storage.child("images/" + filename).put(image)
except:
