二、源碼：

 

三、經常使用返回信息：

 

2、post方法簡單使用：

 一、帶數據的post：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"
url = ''.join([host,endpoint])
data = {'key1':'value1','key2':'value2'}

r = requests.post(url,data=data)
#response = r.json()
print (r.text)

輸出：

{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {
    "key1": "value1", 
    "key2": "value2" }, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Content-Length": "23", 
    "Content-Type": "application/x-www-form-urlencoded", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.1"
  }, 
  "json": null, 
  "origin": "183.14.133.88", 
  "url": "http://httpbin.org/post"
}

 

二、帶header的post：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"

url = ''.join([host,endpoint])
headers = {"User-Agent":"test request headers"}

# r = requests.post(url)
r = requests.post(url,headers=headers)
#response = r.json()

輸出：

{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Content-Length": "0", 
    "Host": "httpbin.org", 
    "User-Agent": "test request headers"
  }, 
  "json": null, 
  "origin": "183.14.133.88", 
  "url": "http://httpbin.org/post"
}

 

三、帶json的post：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"

url = ''.join([host,endpoint])
data = {
    "sites": [
                { "name":"test" , "url":"www.test.com" },
                { "name":"google" , "url":"www.google.com" },
                { "name":"weibo" , "url":"www.weibo.com" }
    ]
}

r = requests.post(url,json=data)
# r = requests.post(url,data=json.dumps(data))
response = r.json()

輸出：

{
  "args": {}, 
  "data": "{\"sites\": [{\"url\": \"www.test.com\", \"name\": \"test\"}, {\"url\": \"www.google.com\", \"name\": \"google\"}, {\"url\": \"www.weibo.com\", \"name\": \"weibo\"}]}", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Content-Length": "140", 
    "Content-Type": "application/json", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.1"
  }, 
  "json": {
    "sites": [
      {
        "name": "test", 
        "url": "www.test.com"
      }, 
      {
        "name": "google", 
        "url": "www.google.com"
      }, 
      {
        "name": "weibo", 
        "url": "www.weibo.com" } ] }, 
  "origin": "183.14.133.88", 
  "url": "http://httpbin.org/post"
}

 

四、帶參數的post：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"

url = ''.join([host,endpoint])
params = {'key1':'params1','key2':'params2'}

# r = requests.post(url)
r = requests.post(url,params=params)
#response = r.json()
print (r.text)

輸出：

{
  "args": {
    "key1": "params1", 
    "key2": "params2" }, 
  "data": "", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Content-Length": "0", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.1"
  }, 
  "json": null, 
  "origin": "183.14.133.88", 
  "url": "http://httpbin.org/post?key2=params2&key1=params1"
}

 

五、普通文件上傳：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"

url = ''.join([host,endpoint])
#普通上傳
files = {
            'file':open('test.txt','rb')
        }

r = requests.post(url,files=files)
print (r.text)

輸出：

{
  "args": {}, 
  "data": "", 
  "files": {
    "file": "hello world!\n" }, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Content-Length": "157", 
    "Content-Type": "multipart/form-data; boundary=392865f79bf6431f8a53c9d56c62571e", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.1"
  }, 
  "json": null, 
  "origin": "183.14.133.88", 
  "url": "http://httpbin.org/post"
}

 

六、定製化文件上傳：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"

url = ''.join([host,endpoint])
#自定義文件名，文件類型、請求頭
files = {
        'file':('test.png',open('test.png','rb'),'image/png')
}

r = requests.post(url,files=files)
print (r.text)heman793

輸出比較在，就不帖了。

 

七、多文件上傳：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"

url = ''.join([host,endpoint])
#多文件上傳
files = [
    ('file1',('test.txt',open('test.txt', 'rb'))),
    ('file2', ('test.png', open('test.png', 'rb')))
    ]

r = requests.post(url,files=files)
print (r.text)

輸出上，太多內容，不帖了。

 

八、流式上傳：

# -*- coding:utf-8 -*-
import requests
import json

host = "http://httpbin.org/"
endpoint = "post"

url = ''.join([host,endpoint])

#流式上傳
with open( 'test.txt' ) as f:
    r = requests.post(url,data = f)

print (r.text)

輸出：

{
  "args": {}, 
  "data": "hello world!\n", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Content-Length": "13", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.1"
  }, 
  "json": null, 
  "origin": "183.14.133.88", 
  "url": "http://httpbin.org/post"
}
