我有一個jQuery的Ajax調用,就像這樣:如何使Flask /保持Ajax HTTP連接處於活動狀態?
$("#tags").keyup(function(event) {
$.ajax({url: "/terms",
type: "POST",
contentType: "application/json",
data: JSON.stringify({"prefix": $("#tags").val() }),
dataType: "json",
success: function(response) { display_terms(response.terms); },
});
我有一個像瓶法這樣:
@app.route("/terms", methods=["POST"])
def terms_by_prefix():
req = flask.request.json
tlist = terms.find_by_prefix(req["prefix"])
return flask.jsonify({'terms': tlist})
tcpdump的顯示了HTTP對話框:
POST /terms HTTP/1.1
Host: 127.0.0.1:5000
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0

然而,瓶答覆無需保持活力。
HTTP/1.0 200 OK

Content-Length: 445

{"terms": [...]}
是否確實存在保持活動狀態?
