ajax - Angularjs + Flask-wtf : Bad request 400

Question

我在 wtf-forms 中遇到了一个非常奇怪的问题，我使用 angularjs $http-module 发送请求。初始化 WTForm 后，我收到一个 错误请求:400 错误。出于测试目的，我禁用了 csrf 保护。我真的不知道在哪里寻找问题。以下是最小的失败:

Angularjs 服务发送请求:

var data = new FormData();
data.append('surname', _gifter.surname);
data.append('lastname', _gifter.lastname);
data.append('email', _gifter.email);
data.append('email_confirm', _gifter.email_confirm);
data.append('prize', gift.prize);

$http.post('ajax/claim/' + DataProvider.gift.id + '/', data)

flask 路线:

@app.route('/ajax/claim/<int:gift_id>/', methods = ['POST'])
def claim_gift(gift_id):
    print("request:" + request.data)
    claim_form = ClaimGiftForm(csrf_enabled=False)
    return 'success'

WT表格:

class ClaimGiftForm(Form):
    surname = TextField(
        validators=[validators.Required()])
    lastname = TextField(
        validators=[validators.Required()])
    email = EmailField(
        validators = [
            validators.email(),
            validators.Required()])
    email_confirm = EmailField(
        validators = [
            validators.Required(),
            validators.EqualTo()])
    prize = IntegerField()

当我打印请求时(参见“Flask route”)，数据似乎没问题 - 一切都正确传输。但是在初始化表单时，我得到了上述错误。

编辑1:我刚刚发现，出于某种原因 request.form MultiDict 为空，尽管 request.data包含预期的数据。但是我不知道为什么会这样。

编辑2: pprint(request.data)给出:

你的 JavaScript 有 email_confirmed但是表单的字段是email_confirm .
