如何在python请求中使用相同的键发布多个值?

问题描述

requests.post(url, data={'interests':'football','interests':'basketball'})

我试过这个，但它不起作用.我如何在 interests 字段中发布 football 和 basketball ?

解决方案

字典键必须唯一，不能重复.您可以改用一系列键值元组，并将其传递给 data:

requests.post(url, data=[('interests', 'football'), ('interests', 'basketball')])

或者，将data字典的值lists；列表中的每个值都用作单独的参数条目:

requests.post(url, data={'interests': ['football', 'basketball']})

演示 POST 到 http://httpbin.org:

>>>进口请求>>>url = 'http://httpbin.org/post'>>>r = requests.post(url, data=[('interests', 'football'), ('interests', 'basketball')])>>>请求体'兴趣=足球&兴趣=篮球'>>>r.json()['表单']{u'interests': [u'football', u'basketball']}>>>r = requests.post(url, data={'interests': ['football', 'basketball']})>>>请求体'兴趣=足球&兴趣=篮球'>>>r.json()['表单']{u'interests': [u'football', u'basketball']}

requests.post(url, data={'interests':'football','interests':'basketball'})

I tried this, but it is not working. How would I post football and basketball in the interests field?

解决方案

Dictionary keys must be unique, you can't repeat them. You'd use a sequence of key-value tuples instead, and pass this to data:

requests.post(url, data=[('interests', 'football'), ('interests', 'basketball')])

Alternatively, make the values of the data dictionary lists; each value in the list is used as a separate parameter entry:

requests.post(url, data={'interests': ['football', 'basketball']})

Demo POST to http://httpbin.org:

>>> import requests
>>> url = 'http://httpbin.org/post'
>>> r = requests.post(url, data=[('interests', 'football'), ('interests', 'basketball')])
>>> r.request.body
'interests=football&interests=basketball'
>>> r.json()['form']
{u'interests': [u'football', u'basketball']}
>>> r = requests.post(url, data={'interests': ['football', 'basketball']})
>>> r.request.body
'interests=football&interests=basketball'
>>> r.json()['form']
{u'interests': [u'football', u'basketball']}
