how could I set cookie followed by a redirect request?

[shanechiu]

There was problem when I tried to grab BAIDU tongji infor.

When I logined success, there was a 302 redirection to main page.

That means the internal redirect was from https://tongji.baidu.com/web/welcome/ico?s=sdfsdfsdfsdf to s://tongji.baidu.com/web/12323243/overview/index?siteId=sdfsf.

I wonder know that how does the program(may be the broswer? I am also not clear. LOL) pass the cookie from the 320 page to the destination page? and Why?

Could anyone do me a favor? Thanks in advace.

Append:

302 page : https://tongji.baidu.com/web/welcome/ico?s=sdfsdfsdfsdf

destination page: s://tongji.baidu.com/web/12323243/overview/index?siteId=sdfsf

Chinese please or go to Stack Overflow

@Cooky I am a little worried about whether this question lives up to the Stack Overflow's strict standard.

不知道你看得懂中文不
中文答案：
1. http 是无状态的
2. cookie 是通过 header 传递的
3. 留意一下 cookie 的域

Because the cookie is shared by same domain

@vincenttone well, Is it that means the 302 page request cookie will also pass to the destination page by header and it also acts as a request cookie in the destination page?

logined 是什么

[shanechiu]

@fml87 a past tense of word "login", it means events or actions happen in the past.

[vincenttone]

@shanechiu 如果你想理解 cookie 在 302 页面中的表现，就必须先了解 cookie 在普通页面中的表现。
如我刚才所说：
1. http 是无状态的
这个是前提。
cookie 存在本地，无状态的情况下，不关心你有没有做 302 跳转。

@vincenttone Thanks for your kindness and patience. There seems like a outline about this.

之前刚做了，用 session 啊，统计后台设置个第三方密码，然后 post 给他，保持 session 去请求其他页面，接着统计里的数据随便拿~ 那去参考下把；我是 py 新手；

```
##百度统计的第三查看密码，登录并获得 session 和 siteid
idwd = {'passwd': '66666'}
S = Session()
logined = S.post("https://tongji.baidu.com/web/welcome/ico?s=8dfdafdafadfa4bccd", data=idwd, headers=REQ_HEADERS)

#获得 siteid，并转换成字符串
siteid= str(logined.url.split("=")[1])
webid = str(logined.url.split("/")[4])



##搜索词的 post 参数
keyjson = {"siteId":siteid,"st":"","et":"","st2":"","et2":"","indicators":"['pv_count','visitor_count','ip_count','bounce_ratio','avg_visit_time']","order":"pv_count,desc","offset":"","pageSize":"","target":"-1","flag":"indicator","source":"","isGroup":"0","clientDevice":"all","reportId":"12","method":"source/searchword/a","queryId":""}

readkeyjson = S.post("https://tongji.baidu.com/web/"+webid+"/ajax/post", data=keyjson, headers=REQ_HEADERS)


#按文本读取
jsondata = readkeyjson.text
#格式化 json
readjsondict = json.loads(jsondata)

keyNamejson = readjsondict['data']['items'][0]
for items in keyNamejson:
items2 = items
print(items2[0]['name'])

```

@yospan well, I do not know whether your method is workable. But thank you all the same.
