python接口自動化3-自動發帖（session）【轉載】
本篇轉自博客：上海-悠悠
原文地址：http://www.cnblogs.com/yoyoketang/tag/python%E6%8E%A5%E5%8F%A3%E8%87%AA%E5%8A%A8%E5%8C%96/
前言
上一篇模擬登錄博客園，但這只是第一步，一般登錄後，還會有其它的操作，如發帖，評論等，這時候如何保持會話呢？
（敲黑板！！！由於博客園最近登錄機制變了，登錄全部走cookie登錄）
一、session簡介
1.查看幫助文檔,貼了一部分，後面省略了
>>import requests
>>help(requests.session())
class Session(SessionRedirectMixin)
| A Requests session.
|
| Provides cookie persistence, connection-pooling, and configuration.
|
| Basic Usage::
|
| >>> import requests
| >>> s = requests.Session()
| >>> s.get(‘http://httpbin.org/get‘)
| <Response [200]>
|
| Or as a context manager::
|
| >>> with requests.Session() as s:
| >>> s.get(‘http://httpbin.org/get‘)
| <Response [200]>
二、使用session登錄
1.使用session登錄只需在上一篇基礎上稍做修改
# coding:utf-8
import requests
url = "https://passport.cnblogs.com/user/signin"
headers = {
頭部信息已省略
}
payload = {"input1":"xxx",
"input2":"xxx",
"remember":True}
# r = requests.post(url, json=payload, headers=headers,verify=False)
# 修改後如下
s = requests.session()
r = s.post(url, json=payload, headers=headers,verify=False)
print r.json()
三、保存編輯
1.先打開我的隨筆，手動輸入內容後，打開fiddler抓包
2.把body的參數內容寫成字典格式，有幾個空的參數不是必填的，可以去掉
body = {"__VIEWSTATE": "",
"__VIEWSTATEGENERATOR":"FE27D343",
"Editor$Edit$txbTitle":"這是我的標題：上海-悠悠",
"Editor$Edit$EditorBody":"<p>這裏是中文內容：http://www.cnblogs.com/yoyoketang/</p>",
"Editor$Edit$Advanced$ckbPublished":"on",
"Editor$Edit$Advanced$chkDisplayHomePage":"on",
"Editor$Edit$Advanced$chkComments":"on",
"Editor$Edit$Advanced$chkMainSyndication":"on",
"Editor$Edit$lkbDraft":"存為草稿",
}
3.用上面的session繼續發送post請求
4.執行後，查看我的草稿箱就多了一條新增的了
四、參考代碼
# coding:utf-8
import requests
# 先打開登錄首頁，獲取部分cookie
url = "https://passport.cnblogs.com/user/signin"
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0"
} # get方法其它加個ser-Agent就可以了
s = requests.session()
r = s.get(url, headers=headers,verify=False)
print s.cookies
# 添加登錄需要的兩個cookie
c = requests.cookies.RequestsCookieJar()
c.set(‘.CNBlogsCookie‘, ‘這裏是抓到的‘) # 填上面抓包內容
c.set(‘.Cnblogs.AspNetCore.Cookies‘,‘這裏是抓到的‘) # 填上面抓包內容
c.set(‘AlwaysCreateItemsAsActive‘,"True")
c.set(‘AdminCookieAlwaysExpandAdvanced‘,"True")
s.cookies.update(c)
print s.cookies
# 登錄成功後保存編輯內容
r1 = s.get("https://i.cnblogs.com/EditPosts.aspx?opt=1", headers=headers, verify=False)
# 保存草稿箱
url2= "https://i.cnblogs.com/EditPosts.aspx?opt=1"
body = {"__VIEWSTATE": "",
"__VIEWSTATEGENERATOR":"FE27D343",
"Editor$Edit$txbTitle":"這是3111",
"Editor$Edit$EditorBody":"<p>這裏111：http://www.cnblogs.com/yoyoketang/</p>",
"Editor$Edit$Advanced$ckbPublished":"on",
"Editor$Edit$Advanced$chkDisplayHomePage":"on",
"Editor$Edit$Advanced$chkComments":"on",
"Editor$Edit$Advanced$chkMainSyndication":"on",
"Editor$Edit$Advanced$txbEntryName":"",
"Editor$Edit$Advanced$txbExcerpt":"",
"Editor$Edit$Advanced$tbEnryPassword":"",
"Editor$Edit$lkbDraft":"存為草稿",
}
r2 = s.post(url2, data=body, verify=False)
print r.content
