Question

我有一个问题，当我尝试POST表单数据时，烧瓶会给我400个错误的请求类型，错误的请求语法，错误的请求版本

@app.route('/scrape', methods=['GET', 'POST'])
def scrape():
if request.method == 'POST': # ajax method
    print "i reached here"
    scrape_params = {
        "market_name": request.form.get('market'),
        "market_id": request.form.get('market-id'),
        "rescrape": request.form.get('rescrape'),
        "update": request.form.get('update'),
        "with_investments": request.form.get('with_investments')
    }
    angellist.scrape(scrape_params, socketio);
    return json.dumps({'success':True}), 200, {'ContentType':'application/json'}
else:
    return render_template('scrape.html')

相应的html表单是

`

<form id="scrape_form" name="scrape" action="scrape" method="post" accept-charset="utf-8">
                <ul>
                    <li>
                        <label for="market">Choose Market</label>
                        <input id="input_market" type="text" name="market" placeholder="Market" required>
                        <input type="hidden" id="market-id" name="market-id"/>
                    </li>
                    <li>
                        <span title="Rescrapes all investor information" class="checkbox-label">
                        <input type="checkbox" id="rescrape-checkbox" name="rescrape" value="true">Rescrape</span>
                        <span title="Rescrapes all companies" class="checkbox-label">
                        <input type="checkbox" id="update-checkbox" name="update" value="true">Update</span>
                        <span title="Scrapes all investments information for investors" class="checkbox-label">
                        <input type="checkbox" id="investments-checkbox" name="with_investments" value="true">Get Investments</span>
                    <li style="text-align: center;">
                        <input type="submit" value="Go" disabled="disabled">
                    </li>
                </ul>
            </form>

`

js文件中的ajax部分

`

 $("#scrape_form").submit(function (ev) {
    var frm = $(this);
    ev.preventDefault();
$.ajax({
        type: 'POST',
        url: "/scrape",
        data: frm.serialize(),
        success: function (data) {
          displayLoadingScreen();
          console.log("Scraping should have begun listen for socket events");
          updateTimeout(socket);
        },
        fail: function() {
          socket.disconnect();
        }
      });

`

我得到的控制台输出是

Answer 1

您是否尝试过使用https？因此，无需加载http://127.0.0.1:5000/scrape，而是在浏览器中加载https://127.0.0.1:5000/scrape（取决于端口）。我有一个类似的错误输出，这对我来说是有用的：）
