import requests

r = requests.get(url,headers)
print (r.text)

GET http://xxx"color: #800000">程序把我的请求头信息当做参数放到了URL里

那就是我请求的时候request函数Header信息参数用错了
又重新看了一下Requests库的Headers参数使用方法，发现有一行代码写错了，在使用request.get（）方法时要把参数 “headers =“写出来 
更改如下：


import requests
url = 'http://xxx"Host":"xxx.com",
 "Connection": "keep-alive",
 "Accept": "application/json, text/javascript, */*; q=0.01",
 "User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.59 Safari/537.36",
 "X-Requested-With": "XMLHttpRequest",
 "Referer": "http://app.jg.eastmoney.com/html_Report/index.html",
 "Accept-Encoding": "gzip,deflate",
 "Accept-Language": "en-us,en",
 "Cookie":"xxx"
}
r = requests.get(url,headers=headers)




然后去查看Fiddler中的请求。

此次python中的请求头已经正常了，请求详细信息如下


GET http://xxx"htmlcode">

{"Id":"6202c187-2fad-46e8-b4c6-b72ac8de0142","ReturnMsg":"加载失败！"} 




因为一般cookie都会在短时间内过期，所以更新了cookie，然后请求成功

需要注意的是用程序爬虫一定要把Header设置好，这个app如果反爬的时候封ip的话可能就麻烦了。
