如何在 CherryPy 中接收来自 POST 请求的 JSON?
我去过this page ,尽管它很好地解释了 API、它的参数以及它的作用;我似乎无法弄清楚如何使用它们将传入的 JSON 解析为对象。
这是我目前所拥有的:
import cherrypy
import json
from web.models.card import card
from web.models.session import getSession
from web.controllers.error import formatEx, handle_error
class CardRequestHandler(object):
@cherrypy.expose
def update(self, **jsonText):
db = getSession()
result = {"operation" : "update", "result" : "success" }
try:
u = json.loads(jsonText)
c = db.query(card).filter(card.id == u.id)
c.name = u.name
c.content = u.content
rzSession.commit()
except:
result["result"] = { "exception" : formatEx() }
return json.dumps(result)
还有,这是我发帖的 jquery 调用
function Update(el){
el = jq(el); // makes sure that this is a jquery object
var pc = el.parent().parent();
pc = ToJSON(pc);
//$.ajaxSetup({ scriptCharset : "utf-8" });
$.post( "http://localhost/wsgi/raspberry/card/update", pc,
function(data){
alert("Hello Update Response: " + data);
},
"json");
}
function ToJSON(h){
h = jq(h);
return {
"id" : h.attr("id"),
"name" : h.get(0).innerText,
"content" : h.find(".Content").get(0).innerText
};
}
最佳答案
Python
import cherrypy
class Root:
@cherrypy.expose
@cherrypy.tools.json_out()
@cherrypy.tools.json_in()
def my_route(self):
result = {"operation": "request", "result": "success"}
input_json = cherrypy.request.json
value = input_json["my_key"]
# Responses are serialized to JSON (because of the json_out decorator)
return result
JavaScript
//assuming that you're using jQuery
var myObject = { "my_key": "my_value" };
$.ajax({
type: "POST",
url: "my_route",
data: JSON.stringify(myObject),
contentType: 'application/json',
dataType: 'json',
error: function() {
alert("error");
},
success: function() {
alert("success");
}
});
