webapp2-如何发布表单数据-App Engine [英] webapp2 - how to post form data - app engine

问题描述

在从表单发布数据并使用webapp2处理数据时遇到一些麻烦.

Having some trouble posting data from form and handling it with webapp2.

我不确定一般如何在webapp2中处理来自表单的数据，包括使用表单操作将数据发布到哪个页面.

I'm not sure how to handle data from a form in webapp2 in general, including which page to post the data to with the form action.

我的表单在"/schedule/create-consult"页面上.并且我最初正在测试将前两个字段提交到同一页面(即，名字和姓氏发布到/schedule/create-consults).

My form is on the page '/schedule/create-consult'. and I'm initially testing submitting the first two fields to the same page (ie. first name and last name being posted to /schedule/create-consults).

我的表单如下

<form method="post" action="/schedule/create-consult">
    <div class="row">
        <div class="col-md-6">
            <label>First Name</label>
            <input class="form-control input-lg" type="text" name="first_name" />
            <br/>
        </div>
        <div class="col-md-6">
            <label>Last Name</label>
            <input class="form-control input-lg" type="text" name="last_name" />
        </div>
        <input type="submit" value="save">
    </div>
</form>

当我单击保存"按钮时，我收到消息:

When I click the Save button I get the message:

405不允许使用的方法-此资源不允许使用POST方法.

我的路线看起来像这样

app = webapp2.WSGIApplication([
    ('/', MainPage),
    ('/schedule', SchedulePage),
    ('/consults', ConsultsPage),
    ('/schedule/create-consult', CreateConsultPage),
    ('/consults/john-smith-030617-0930', JohnSmithPage)
], debug=True)

我的CreateConsultsPage处理程序如下

My handler for CreateConsultsPage looks like this

class CreateConsultPage(webapp2.RequestHandler):
    def get(self):
    template = JINJA_ENVIRONMENT.get_template('/templates/create-consult.html')  
    self.response.out.write(template.render())

我的app.yaml如下:

And my app.yaml is as follows:

 runtime: python27
 api_version: 1
 threadsafe: true

 handlers:
 - url: /css
   static_dir: css
 - url: /images
   static_dir: images
 - url: /js
   static_dir: js
 - url: /
   script: main.app
 - url: /schedule
   script: main.app
 - url: /consults
   script: main.app
 - url: /schedule/create-consult
   script: main.app
 - url: /consults/john-smith-030617-0930
   script: main.app

 libraries:
 - name: webapp2
   version: latest
 - name: jinja2
   version: latest

推荐答案

您正在使用post方法提交表单.您必须在处理程序类中定义post函数，以获取提交的表单数据.这样可以解决您的问题.

You are submitting the form using post method. You have to define the post function in your handler class to get the submitted form data. This will solve your problem.

class CreateConsultPage(webapp2.RequestHandler):
    def get(self):
        template = JINJA_ENVIRONMENT.get_template('/templates/create-consult.html')  
        self.response.out.write(template.render())

    def post(self):
        first_name = self.request.get('first_name')
        last_name = self.request.get('last_name')
