requests模塊

想要經過python來發送網絡請求，能夠使用內置的urllib2模塊

可是requests模塊使用起來更簡潔 

pip install requests

一、發送get請求

url1 = 'http://118.24.3.xx/api/user/stu_info'
res = requests.get(url1,params={'stu_name':'xiaohei'})#發送get請求，params填寫參數
print(res.json())#返回數據是json，把結果轉爲字典

二、發送post請求

url2 = 'http://118.24.3.xx/api/user/login'
data = {"username":"niuhanyang","passwd":"aA123456"}#發送post請求，data填寫參數
res = requests.post(url2,data=data)
print(res.json())

三、發送post請求，json傳參

url3 = 'http://118.24.3.xx/api/user/add_stu'
data =  {
    "name":"requeslina",
    "grade":"天蠍座",
    "phone":18611532955,
    "sex":"男",
    "age":28,
    "addr":"河南省濟源市北海大道32號"
  }
res = requests.post(url3,json=data)#post請求，json傳參
print(res.json())

四、帶cookies的請求

url4 = 'http://118.24.3.xx/api/user/gold_add'
data = {'stu_id':15,'gold':200}
cookie = {'niuhanyang':'abd9a0995f4696e1a60133220b32037a'}
res = requests.post(url4,data=data,cookies=cookie)#帶cookie的請求
print(res.json())#json直接把返回結果轉成字典

五、帶header的請求

url5 = 'http://118.24.3.xx/api/user/all_stu'
header = {'Referer':'http://api.nnzhp.cn/'}
res = requests.get(url5,headers=header)#帶header的請求
print(res.json())#json直接把返回結果轉成字典

六、字符串的響應數據

url6 = 'http://www.nnzhp.cn'
res = requests.get(url6)
print(res.text)#字符串的響應數據

七、請求獲取二進制數據，能夠用來下載

url7 ='http://qiniuuwmp3.changba.com/1084511584.mp3'
res = requests.get(url7)
print(res.content)#獲取二進制的數據
with open('魔鬼中的天使.mp3','wb') as fw:#wb是寫二進制的東西 rb讀二進制的
    fw.write(res.content)
print(res.status_code)#響應狀態碼

八、下載一個圖片

url8 ='https://aliimg.changba.com/cache/photo/855e5493-f018-44db-8892-c8660649327b_640_640.jpg'
res = requests.get(url8,verify=False)#若是是https 加verify=False參數
with open('lina.jpg','wb') as fw:
    fw.write(res.content)

九、上傳文件請求

url9 = "http://118.24.3.xx/api/file/file_upload"
data = {'file':open('lina.jpg','rb')}
res = requests.post(url9,files=data)#上傳文件
print(res.text)
