问题描述
我正在尝试使用jquery进行跨源请求,但是它一直被消息拒绝
I am trying to make a cross origin request using jquery but it keeps being reject with the message
我正在使用flask,heroku和jquery
I am using flask, heroku, and jquery
客户端代码如下:
$(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heroku端,我正在使用烧瓶,就像这样
on the heroku side i am using flask and it is like this
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()
推荐答案
这对我有用当我部署到Heroku时。
Here is what worked for me when I deployed to Heroku.
通过运行安装flask-cors-
pip install -U flask-cors
from flask import Flask
from flask_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!"
