Question

我正在尝试通过ajax和wtforms验证表单，我有一个包含这样一个字段的表单：

const urlP = require('url');
const path = require('path');
const http = require('http');
const connect = require('connect');
const har = require('./har');

const proxiedServer = 'http://localhost:8888';

// Proxy server
http.createServer((req, res) => {
  console.log(`Proxy: Got ${req.url}`);

  const _r = http.request(
    Object.assign(
      {},
      urlP.parse(proxiedServer),
      {
        method: req.method,
        path: req.url
      }
    ),
    _res => {
      res.writeHead(_res.statusCode, _res.headers);
      _res.pipe(res);
    }
  );

  req.pipe(_r);

}).listen(3124, () => {
  console.log("Listening on 3124");
});

const middleware = connect();
middleware.use(har({
  harOutputDir: path.resolve(process.cwd(), 'har/')
}));

middleware.use((req, res) => {
  console.log('Proxied server: ', req.url);
  let b = '';
  req.on('data', c => {
    b += c;
  });
  req.on('end', () => {
    console.log('Proxied server: ', b);
  });
  res.writeHead(200);
  res.end('ok');
});


http.createServer(middleware).listen(8888, () => {
  console.log('proxied server listening on 8888');
});

我的服务器端代码是这样的：

name = StringField('Name :', description = "enter your name", validators=[InputRequired(message='please enter your name')])

我通过json发送字段数据然后我将其设置为字段，我检查它并且它的数据存在于myform.data中但是在验证后仍然存在InputRequired错误。

Answer 1

您可以在表单类本身内验证表单。

views.py

这样您只需从sender.py文件中的视图函数调用validate方法进行验证。

Answer 2

您通过ajax发送数据并希望服务器端验证只需使用request.form

@app.route('/validation', methods=['get', 'post'])
def validation():
    data = request.get_json(force = True)
    myform = MyForm(request.form)
    if myform.validate():
        #do something
        #return somthing
    else:
        return jsonify(myform.errors)

在服务器端更改字段数据后，wtfroms验证似乎不起作用
