Python request.method默认进入烧瓶

我在Flask中创建了一个表单，希望提交某些需要处理的值。但是使用的方法被默认为GET，即使我在表单中已将该方法指定为post

以下是相关代码文件的详细信息： app.py

test.html

<form method="post" class="text-center" style="color: #757575;" action="">

                <div class="form-row">
                    <div class="col">
                        <!-- First name -->
                        <div class="md-form">
                            <input type="text" name="firstname" value="{{request.form.firstname}}" class="form-control">
                            <label for="materialRegisterFormFirstName">First name</label>
                        </div>
                    </div>
                    <div class="col">
                        <!-- Last name -->
                        <div class="md-form">
                            <input type="text" name="lastname" value="{{request.form.lastname}}" class="form-control">
                            <label for="materialRegisterFormLastName">Last name</label>
                        </div>
                    </div>
                </div>

                <!-- File Upload -->
                <div class="md-form">
                    <input type="file" id="fileupload" class="form-control">


                </div>

                <input class="btn btn-info btn-block" type="submit" value="Submit">
            </form>

加载127.0.0.1:5000/测试时，该方法默认为post，响应“错误”。方法始终为GET

<form method="post" class="text-center" style="color: #757575;" action="/test" method="post">

            <div class="form-row">
                <div class="col">
                    <!-- First name -->
                    <div class="md-form">
                        <input type="text" name="firstname" value="{{request.form.firstname}}" class="form-control">
                        <label for="materialRegisterFormFirstName">First name</label>
                    </div>
                </div>
                <div class="col">
                    <!-- Last name -->
                    <div class="md-form">
                        <input type="text" name="lastname" value="{{request.form.lastname}}" class="form-control">
                        <label for="materialRegisterFormLastName">Last name</label>
                    </div>
                </div>
            </div>

            <!-- File Upload -->
            <div class="md-form">
                <input type="file" id="fileupload" class="form-control">


            </div>

            <input class="btn btn-info btn-block" type="submit" value="Submit">

通过在action属性中添加“route”并定义表单提交的方法，您可以执行所需的目标。

我事先添加了method=“post”属性。现在，即使在我定义了action=“/test”之后，该方法仍然是GET

<form method="post" class="text-center" style="color: #757575;" action="/test" method="post">

            <div class="form-row">
                <div class="col">
                    <!-- First name -->
                    <div class="md-form">
                        <input type="text" name="firstname" value="{{request.form.firstname}}" class="form-control">
                        <label for="materialRegisterFormFirstName">First name</label>
                    </div>
                </div>
                <div class="col">
                    <!-- Last name -->
                    <div class="md-form">
                        <input type="text" name="lastname" value="{{request.form.lastname}}" class="form-control">
                        <label for="materialRegisterFormLastName">Last name</label>
                    </div>
                </div>
            </div>

            <!-- File Upload -->
            <div class="md-form">
                <input type="file" id="fileupload" class="form-control">


            </div>

            <input class="btn btn-info btn-block" type="submit" value="Submit">
        </form>
