Question

我正在请求一个带有Python脚本的Ajax网站并获取http://www.yurticikargo.com/bilgi-servisleri/Sayfalar/en-yakin-sube.aspx的城市和分支机构

我完成了发布的第一步 {cityID: 34}到此网址并获取JSON输出。

http://www.yurticikargo.com/_layouts/ArikanliHolding.YurticiKargo.WebSite/ajaxproxy-sswservices.aspx/GetTownByCity

但我无法使用Python检索JSON输出，尽管我已成功使用Chrome Advanced Rest Client Extension，发布{cityID:54,townID:5416,unitOnDutyFlag:null,closestFlag:2}

http://www.yurticikargo.com/_layouts/ArikanliHolding.YurticiKargo.WebSite/ajaxproxy-unitservices.aspx/GetUnit

所有源代码都在这里

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import requests
import json


class Yurtici(object):

    baseUrl = 'http://www.yurticikargo.com/'
    ajaxRoot = '_layouts/ArikanliHolding.YurticiKargo.WebSite/ajaxproxy-sswservices.aspx/'
    getTown = 'GetTownByCity'
    getUnit = 'GetUnit'
    urlGetTown = baseUrl + ajaxRoot + getTown
    urlGetUnit = baseUrl + ajaxRoot + getUnit 
    headers = {'content-type': 'application/json','encoding':'utf-8'}

    def __init__(self):
        pass

    def ilceler(self, plaka=34): # Default testing value
        payload = {'cityId':plaka}
        url = self.urlGetTown
        r = requests.post(url, data=json.dumps(payload), headers=self.headers)
        return r.json() # OK

    def subeler(self, ilceNo=5902): # Default testing value
        # 5902 Çerkezköy 
        payload=  {'cityID':59,'townID':5902,'unitOnDutyFlag':'null','closestFlag':0}
        url = self.urlGetUnit
        headers = {'content-type': 'application/json','encoding':'utf-8'}
        r = requests.post(url, data=json.dumps(payload), headers=headers)
        print  r.status_code, r.raw.read()

if __name__ == '__main__':        
    a = Yurtici()
    print a.ilceler(37) # OK
    print a.subeler()   # NOT OK !!!

您的代码未发布到您在文字示例中使用的相同网址。

让我们向后看一下。首先，让我们来看看失败的POST。

url = self.urlGetUnit
headers = {'content-type': 'application/json','encoding':'utf-8'}
r = requests.post(url, data=json.dumps(payload), headers=headers)

因此我们发布的网址等于self.urlGetUnit。好吧，让我们来看看它是如何定义的：

baseUrl = 'http://www.yurticikargo.com/'
ajaxRoot = '_layouts/ArikanliHolding.YurticiKargo.WebSite/ajaxproxy-sswservices.aspx/'
getUnit = 'GetUnit'
urlGetUnit = baseUrl + ajaxRoot + getUnit

如果您在urlGetUnit中完成工作，则会得到该网址为http://www.yurticikargo.com/_layouts/ArikanliHolding.YurticiKargo.WebSite/ajaxproxy-sswservices.aspx/GetUnit的网址。让我们将此与您在Chrome中使用的网址一起比较差异：

http://www.yurticikargo.com/_layouts/ArikanliHolding.YurticiKargo.WebSite/ajaxproxy-sswservices.aspx/GetUnit
http://www.yurticikargo.com/_layouts/ArikanliHolding.YurticiKargo.WebSite/ajaxproxy-unitservices.aspx/GetUnit

看到区别？ ajaxRoot对于两个网址都不相同。对此进行排序，您将获得JSON响应。
