python requests post参数的异同

Posted on | In | | 浏览 次

python requests包在post数据时根据data参数的不同，所发送的数据格式也不同，例如在request.post(url,data=)这里就有如下几种方式

  • requests.post(url,json = data)除了可以自行对 dict 进行编码，你还可以使用 json 参数直接传递，然后它就会被自动编码。这是 2.4.2 版的新加功能
  • requests.post(url,data = json.dumps(data))
  • requests.post(url,data = data)

为了便于记忆这里实验记录一下，实验通过nc命令监听端口，查看接收到的原始数据，按照如上顺序分别实验发送数据+接收到的数据

data = {
    'key':['123-+%/','456e":']
}
requests.post(url,json = data)

key=123-%2B%25%2F&key=456e%22%3A

通过如上实验可以发现，使用json={}和data = json.dumps()的效果是一样的，区别仅仅在于有无Content-Type：application/json，而使用data = {}这种形式发送的数据是表单形式，后面有机会再详细研究一下json和www-form方式的区别：）
