Python的谷歌应用程序引擎的JSON对象代替接收字符串 [英] Python Google App Engine Receiving a string in stead of JSON object
本文介绍了Python的谷歌应用程序引擎的JSON对象代替接收字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我用下面
脚本发送从一个android的HTTP POST请求到服务器 URI网站=新的URI(http://venkygcm.appspot.com); HttpClient的客户端=新DefaultHttpClient();
HttpPost要求=新HttpPost(网站); request.setHeader(内容类型,应用/ JSON); 字符串currentDateTimeString = DateFormat.getDateTimeInstance()格式(新的Date()); JSONObject的OBJ =新的JSONObject();
obj.put(REG_ID,注册ID发送到服务器);
obj.put(日期时间,currentDateTimeString); StringEntity本身=新StringEntity(obj.toString());
request.setEntity(SE);
HTT presponse响应= client.execute(请求); 串出= EntityUtils.toString(response.getEntity());
正如我已经发出了JSON对象,我必须接受服务器的JSON对象。相反,我得到含有人体的数据串。服务器在Python谷歌应用程序引擎的。
进口webapp2的一流的MainPage(webapp2.RequestHandler):
DEF后(个体经营):
self.response.out.write(这是一个POST请求\\ n)
REQ = self.request获取
A = req.get(身体)
self.response.out.write(式(a))的应用= webapp2.WSGIApplication([('/',的MainPage),调试=真)
我想提出什么AK09,但我仍然得到一个字符串类型的对象。应该是什么我的下一个步骤?
进口webapp2的
进口JSON一流的MainPage(webapp2.RequestHandler):
DEF后(个体经营):
self.response.out.write(这是一个POST请求\\ n)
REQ = self.request获取
A = req.get(身体)
B = json.dumps(一) self.response.out.write(式(a))的
self.response.out.write(类型(b))的应用= webapp2.WSGIApplication([('/',的MainPage),调试=真)
解决方案
最后这个code工作
进口webapp2的
进口JSON一流的MainPage(webapp2.RequestHandler):
DEF后(个体经营):
self.response.out.write(这是一个POST请求\\ n)
REQ = self.request获取
A = req.body
B = json.loads(一) self.response.out.write(二)
self.response.out.write(二['REG_ID'])
self.response.out.write(B ['日期时间'])
self.response.out.write(类型(b))的应用= webapp2.WSGIApplication([('/',的MainPage),调试=真)
乙出来的要求是类型列表中。
I am sending a HTTP POST request from android to a server using the script below
URI website = new URI("http://venkygcm.appspot.com");
HttpClient client = new DefaultHttpClient();
HttpPost request = new HttpPost(website);
request.setHeader("Content-Type", "application/json");
String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());
JSONObject obj = new JSONObject();
obj.put("reg_id","Registration ID sent to the server");
obj.put("datetime",currentDateTimeString);
StringEntity se = new StringEntity(obj.toString());
request.setEntity(se);
HttpResponse response = client.execute(request);
String out = EntityUtils.toString(response.getEntity());
As I have sent a JSON Object, I must receive a JSON Object in the server. Instead I get a string containing the data of the body. The server is made in Python Google App Engine.
import webapp2
class MainPage(webapp2.RequestHandler):
def post(self):
self.response.out.write(" This is a POST Request \n")
req = self.request
a = req.get('body')
self.response.out.write(type(a))
app = webapp2.WSGIApplication([('/', MainPage)], debug=True)
I tried what AK09 suggested but i still get a string kind of object. What should be my next step?
import webapp2
import json
class MainPage(webapp2.RequestHandler):
def post(self):
self.response.out.write("This is a POST Request \n")
req = self.request
a = req.get('body')
b = json.dumps(a)
self.response.out.write(type(a))
self.response.out.write(type(b))
app = webapp2.WSGIApplication([('/', MainPage)], debug=True)
解决方案
Finally this code worked
import webapp2
import json
class MainPage(webapp2.RequestHandler):
def post(self):
self.response.out.write("This is a POST Request \n")
req = self.request
a = req.body
b = json.loads(a)
self.response.out.write(b)
self.response.out.write(b['reg_id'])
self.response.out.write(b['datetime'])
self.response.out.write(type(b))
app = webapp2.WSGIApplication([('/', MainPage)], debug=True)
b comes out to be of the type List as is required.
