我试图访问正在调用我的休息服务器的客户端IP,但我只是作为响应得到null.Web服务器正在运行,我可以从Web浏览器访问.

我试过了

@Context HttpServletRequest

还有

@Context ContainerRequest请求
request.getRequestHeader("HTTP_FORWARDED")
// HTTP_X_FORWARDED
// HTTP_CLIENT_IP

但是,无论是否成功,响应都为空或空白.

我无法弄清楚为什么我的表单无法验证。我已经确保将 CSRF 字段插入到 HTML 中form.hidden_tag

这是我的注册表单的代码：

from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField, BooleanField
from wtforms.validators import DataRequired, Length, Email, EqualTo


class RegistrationForm(FlaskForm):
    username = StringField('Username', validators=[DataRequired(), Length(min=2, max=20)])
    email = StringField('Email', validators=[DataRequired(), Email()])
    password = PasswordField('Password', validators=[DataRequired()])
    confirm_password = PasswordField('Confirm Password', validators=[DataRequired(), EqualTo(password)])
    submit = SubmitField('Register')

这是我正在检查表单是否经过验证的函数。它确实提交，因为程序将“已提交”打印到我的终端中

@app.route('/register', methods=['GET', 'POST'])
def register():
    form = RegistrationForm()
    if form.is_submitted():
        print("submitted")
    if form.validate_on_submit():
        flash(f'Account created for {form.username.data}!', 'success')
        return redirect(url_for('home'))
    print(forms.errors)
    return render_template('register.html', title='Register', form=form)

使用forms.errors，我收到以下错误消息： …
