使用Python爬虫库requests发送表单数据和JSON数据

导入Python爬虫库Requests

import requests

一、发送表单数据

要发送表单数据，只需要将一个字典传递给参数data

payload = {'key1': 'value1', 'key2': 'value2'}
r = requests.post("http://httpbin.org/post", data=payload)
print(r.text)

{"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/2.14.2"},"json":null,"origin":"110.18.198.88","url":"http://httpbin.org/post"}

二、发送字符串(JSON)数据

将json字符串传递给参数data

import json
url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
r = requests.post(url, data=json.dumps(payload))

将字典传递给参数json

url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
r = requests.post(url,json=payload)
