本文主要是介绍requests请求方式、参数，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

  - 其他请求
  - 参数

get

1、无参数实例

import requestsret = requests.get('https://github.com/timeline.json')
print(ret.text)

输出如下：

{"message":"Hello there, wayfaring stranger. If you’re reading this then you probably didn’t see our blog post a couple of years back announcing that this API would go away: http://git.io/17AROg Fear not, you should be able to get what you need from the shiny new Events API instead.","documentation_url":"https://developer.github.com/v3/activity/events/#list-public-events"}

2、有参数实例

payload = {'key1': 'value1', 'key2': 'value2'}
ret = requests.get("http://httpbin.org/get", params=payload)
print(ret.text)

{"args": {"key1": "value1", "key2": "value2"}, "headers": {"Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Connection": "close", "Host": "httpbin.org", "User-Agent": "python-requests/2.18.4"}, "origin": "39.155.185.105", "url": "http://httpbin.org/get?key1=value1&key2=value2"
}

post

基本POST实例


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

输出如下：

{"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/2.18.4"}, "json": null, "origin": "39.155.185.105", "url": "http://httpbin.org/post"
}

发送请求头和数据实例

import  json
url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}ret1 = requests.post(url, data=json.dumps(payload), headers=headers)
ret2 = requests.post(url, data=json.dumps(payload))print(ret1.text,ret2.text)

输出如下:

{"message":"Not Found","documentation_url":"https://developer.github.com/v3"} {"message":"Not Found","documentation_url":"https://developer.github.com/v3"}

其他请求

requests.get(url, params=None, **kwargs)
requests.post(url, data=None, json=None, **kwargs)
requests.put(url, data=None, **kwargs)
requests.head(url, **kwargs)
requests.delete(url, **kwargs)
requests.patch(url, data=None, **kwargs)
requests.options(url, **kwargs)# 以上方法均是在此方法的基础上构建
requests.request(method, url, **kwargs)
