Jquery 烧瓶;错误:[Errno 32]管道破裂“;当使用;返回重定向(url用于…);

错误,忘记发布错误:

是的,我想我是走错了路。最后,我创建了一个URL,并将其作为jquery响应传回,然后用javascript处理重定向。新的jquery函数如下所示:
$(document).ready(function() {
(function poll() {
setTimeout(function() {
$.ajax({
url: "/status",
type: "GET",
success: function(data) {
if (data.redirect) {
// data.redirect contains the string URL to redirect to
window.location.href = data.redirect;
}
console.log(data.redirect);
},
dataType: "json",
data: {"id": $('#id').text(), "state": $('#state').text()},
complete: poll,
timeout: 2000
})
}, 5000);
})();
});
python是这样的:
@app.route('/status')
def check_deployment_status():
# get all the simpleDB domains
# the list of clusters are used to build the left nav
clusters = sdb_conn.get_domain('clusters')
cluster_id = request.args.get('id', '')
state = request.args.get('state', '')
# get that cluster from the list of clusters
cluster=clusters.get_item(cluster_id)
print "cluster state: " + cluster['state']
print "dashboard state: " + state
if cluster['state'] != state:
#return redirect(url_for('cluster', id=cluster_id))
return jsonify(redirect=url_for('cluster', id=cluster_id))
else:
return 'this'
