jquery – 如何在烧瓶和heroku中启用CORS

我试图使用 jquery做@L_675_1@十字架请求,但是它一直被拒绝与消息

我正在使用烧瓶,英雄和jquery

客户端代码如下所示：

$(document).ready(function() {
    $('#submit_contact').click(function(E){
        e.preventDefault();
        $.ajax({
            type: 'POST',url: 'http://...',// data: [
            //      { name: "name",value: $('name').val()},//      { name: "email",value: $('email').val() },//      { name: "phone",value: $('phone').val()},//      { name: "description",value: $('desc').val()}
            //
            // ],data:"name=3&email=3&phone=3&description=3",crossDomain:true,success: function(msg) {
                alert(msg);
            }
        });
    }); 
});

在英雄方面我正在使用烧瓶,就像这样

from flask import Flask,request
from flask.ext.mandrill import Mandrill
try:
    from flask.ext.cors import CORS  # The typical way to import flask-cors
except ImportError:
    # Path hack allows examples to be run without installation.
    import os
    parentdir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    os.sys.path.insert(0,parentdir)

    from flask.ext.cors import CORS
app = Flask(__name__)

app.config['MANDRILL_API_KEY'] = '...'
app.config['MANDRILL_DEFAULT_FROM']= '...'
app.config['QOLD_SUPPORT_EMAIL']='...'
app.config['CORS_HEADERS'] = 'Content-Type'

mandrill = Mandrill(app)
cors = CORS(app)

@app.route('/email/',methods=['POST'])
def Hello_world():
    name=request.form['name']
    email=request.form['email']
    phone=request.form['phone']
    description=request.form['description']

    mandrill.send_email(
        from_email=email,from_name=name,to=[{'email': app.config['QOLD_SUPPORT_EMAIL']}],text="Phone="+phone+"\n\n"+description
    )

    return '200 OK'

if __name__ == '__main__':
    app.run()

from flask import Flask
from flask.ext.cors import CORS,cross_origin
app = Flask(__name__)
cors = CORS(app)
app.config['CORS_HEADERS'] = 'Content-Type'

@app.route("/")
@cross_origin()
def HelloWorld():
  return "Hello,cross-origin-world!"
