Python post中session和auth 的三种方法

1、方式一，获取session后。存储起来。下次调用时候，传递一个session植即可

#/bin/python
# -*- coding: utf-8 -*-
import requests
from urllib import parse

class  HarborAapi(object):
    def __init__(self,url,username,passwd):
        '''
        @Author: xiajinqi
        :param url:
        :param username:
        :param passwd:
        '''
        print("构造函数")
        self.url = url
        self.username= username
        self.passwd=passwd
        self.session_id_key = "sid"

    def login_get_session(self):
        print("获取session")
        header={
            'User-Agent':'User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36','Content-Type': 'application/x-www-form-urlencoded'
        }
        req_url='%s/c/login'%(self.url)
        req_dict={
            'principal':  self.username,
            'password': self.passwd
        }
        req_data=parse.urlencode(req_dict)
        try :
            res = requests.post(req_url, headers=header, data=req_data)
            print(res.text)
            if  res.status_code==200 :  ### 200位数字不可加"
                self.session_id = res.cookies.get("sid")
                return self.session_id
        except :
            raise Exception("login error,please check your account info!" )

    def get_projects(self):
        print("获取工程")
        header = {
            'User-Agent': 'User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36',
            'Content-Type': 'application/json'
        }
        req_url = '%s/api/projects?page=1&page_size=15' % (self.url)
        req_dict={
            'page': '1',
            'page_size': '15'
        }

        r = requests.get(req_url, cookies={'sid':self.login_get_session()})
        print(r.text)
        print(r.status_code)

### cookies={self.session_id_key: self.session_id}
    def logout(self):
        r=requests.get('%s/c/logout' % (self.url),cookies={'sid': self.session_id})
        print(r.text)

harbor=HarborAapi('http://xx.xxxxx.com','test','00000')
print(harbor.login_get_session())
harbor.get_projects()

方式二通过session 方式发送请求

#/bin/python
# -*- coding: utf-8 -*-
import requests
from urllib import parse

class  HarborAapi(object):
    def __init__(self,url,username,passwd):
        '''
        @Author: xiajinqi
        :param url:
        :param username:
        :param passwd:
        '''
        print("构造函数")
        self.url = url
        self.username= username
        self.passwd=passwd
        self.session_id_key = "sid"

    def login_get_session(self):
        print("获取session")

        header={
            'User-Agent':'User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36','Content-Type': 'application/x-www-form-urlencoded'
        }
        req_url='%s/c/login'%(self.url)
        req_dict={
            'principal':  self.username,
            'password': self.passwd
        }
        req_data=parse.urlencode(req_dict)
        try :
            s = requests.Session()  ###通过session方式请求。会自动保留cookie信息
            res = s.post(req_url, headers=header, data=req_data)
            print(res.text)
            if  res.status_code==200 :  ### 200位数字不可加"
                self.session=s
  #              self.session_id = res.cookies.get("sid")
                print(s)
                return s  #####s中存在cookie植
        except :
            raise Exception("login error,please check your account info!" )

    def get_projects(self):
        print("获取工程")
        header = {
            'User-Agent': 'User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36',
            'Content-Type': 'application/json'
        }
        req_url = '%s/api/projects?page=1&page_size=15' % (self.url)
        req_dict={
            'page': '1',
            'page_size': '15'
        }

        r = self.session.get(req_url)
        print(r.text)
        print(r.status_code)

### cookies={self.session_id_key: self.session_id}
    def logout(self):
        r=requests.get('%s/c/logout' % (self.url),cookies={'sid': self.session_id})
        print(r.text)

harbor=HarborAapi('https:/******','test','1234')
harbor.login_get_session()
harbor.get_projects()

### 返回session对象  

构造函数
获取session

<requests.sessions.Session object at 0x0000000003F0BE80>

方式三：通过auth  和session 相互结合的模式来实现，跨路径访问

#/bin/python
# -*- coding: utf-8 -*-
import requests
from urllib import parse
from requests.auth import HTTPBasicAuth

class  HarborAapi(object):
    def __init__(self,url,auth):
        '''
        @Author: xiajinqi
        :param url:
        '''
        print("构造函数")
        self.url = url
        self.auth=auth
        self.session_id_key = "sid"

    def  setting(self):
        ###定义会话保持ｓ并且设置ｓ的ａｕｔｈ　属性
        self.session=requests.session()
        self.session.auth=self.auth

    def get_projects(self):
        print("获取工程")
        header = {
            'User-Agent': 'User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36',
            'Content-Type': 'application/json'
        }
        #https://harbor.yylending.com:8443/api/projects?page=1&page_size=15
        req_url = '%s/api/projects?page=1&page_size=15' % (self.url)
        req_dict={
            'page': '1',
            'page_size': '15'
        }
        req_data=parse.urlencode(req_dict)
        r = self.session.get(req_url,data=req_dict,headers=header)
        print(r.text)
        print(r.status_code)

auth = HTTPBasicAuth('att','12345')

harbor=HarborAapi('https://xxx.xxxx.com:44',auth)
harbor.setting()  ###
harbor.get_projects()
