发回json到客户端 [英] Send back json to client side

问题描述

我刚开始使用cherrypy进行开发，所以我有点挣扎. 在客户端，我正在选择一些数据，将其转换为json并通过post方法发送到服务器端.然后，我对json进行了一些操作，最后我想将其发送回客户端.因此，问题是如何将修改后的json返回给客户端(浏览器).

I just started developing with cherrypy, so I am struggling a little bit. In client side I am selecting some data, converting it to json and sending to server side via post method. Then I am doing a few operations with json and finally I want to send it back to client side. So the question is how to return modified json to the client side (browser).

服务器端:

  @cherrypy.expose
  def drawChart(self):
        __test = cherrypy.request.body.read().strip()
        logging.debug(__test)
        #...some operations with data

客户端:

function send(JsonArray){
        $.ajax({
            url: '/drawChart',
            type: 'post',
            contentType: 'application/json',
            dataType: 'json',
            success: console.log("Success!"),
            data: JsonArray
        });
}

推荐答案

我的方法是:

 @cherrypy.expose
    def drawChart(self, coordinates):
        cherrypy.response.headers['Content-Type'] = 'application/json'
        listOfCoordiantes = randomData(coordinates)
        return json.dumps(dict(Coordinates=listOfCoordiantes))
