Python Flask webapp从移动图像库上载照片

我有一个烧瓶应用程序，用户可以上传照片到谷歌云存储。选择拍照时，此过程在PC上也可以在手机上正常工作，但从手机图像库上载时，文件不会上载。请帮忙

class Image(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    location = db.Column(db.String(50), unique=True, nullable=False)

class ImageForm(FlaskForm):
    photo = FileField('Add Main Photo', validators=[FileRequired(), FileAllowed(['jpg'])])
    submit = SubmitField('confirm')

def save_picture(form_picture,name):
    picture_path = os.path.join(app.config['UPLOAD_FOLDER'], name)
    output_size = (1000,1000)
    i = Image.open(form_picture)
    i.thumbnail(output_size)
    i.save(picture_path)

    storage_client = storage.Client()
    bucket = storage_client.get_bucket(app.config['BUCKET'])
    blob = bucket.blob(name)
    blob.upload_from_filename(picture_path)
    return picture_path

@app.route('/testupload', methods=['GET', 'POST'])
def testupload():
    form = ImageForm()
    if form.validate_on_submit():
        name = 'ID'+uuid.uuid4().hex[:6]
        filename = secure_filename(name+'.jpg')
        try:
            save_picture(form.photo.data, filename)
            db.session.add(Image(location=filename))
            db.session.commit()
            return redirect(url_for('post'))
        except:
            flash("unsuccess")
            return redirect(url_for('testupload'))
    else:
        return render_template("home.html")

HTML文件

{% extends"layout.html" %}
{% block content %}
<form method="POST" enctype="multipart/form-data">
  {{ form.hidden_tag() }}
  <div>
    {{ form.photo }}
    {{ form.submit }}
  </div>
</form>

你需要描述一下“从相机卷上传”是什么意思（我已经长大了，这对我来说意味着其他的东西），并提供更多关于“文件未上传”（错误、日志等）部分的信息。我指的是当你用手机拍摄照片时手机上的照片存储。问题是，单击form.photo按钮时，您可以浏览文件、从照片库中选择或拍照。如果你拍一张照片。已成功上载图像，但如果选择从照片库中选择，则不会上载图像。在我的情况下，它只是闪烁着“不成功”。嘿@pie，你能提供更多信息让我帮你吗？比如：检查你的谷歌云平台，并提供与此问题相关的日志。此外，请检查您的帐户，如果存在，请向我提供回溯。之后，我会很乐意帮助你。谢谢@methkalkalawi我已经更新了日志。没有错误报告。您添加的请求日志是在

/merchant/product

路径中创建的，而不是在

/testupload

路径中创建的。要么它不是正确的请求日志，要么请求实际上没有发送到正确的路径，这可以解释为什么没有上传。
