Python urllib2 返回JSON

Question

我想从这个URL返回一个JSON对象。我正确地传递了我的API，但是当我去做的时候

data=json.loads(a.read())
print data

我得到这个错误

^{pr2}$

这是我的全部代码

^{3}$

https://developer.onboard-apis.com/docs文档

这个问题没有帮助Python urllib2: Receive JSON response from url

这是a.read（）打印的内容

Answer 1

根据您提供的documentation链接，您省略了Accept头。在

There are two required headers:

1. Accept - set to either
   • application/json
   • application/xml

如果没有这个头，它似乎默认为application/xml，并返回格式为xml而不是{}的信息

要返回json，只需将Accept设置为application/json

weburl.add_header('Accept', 'application/json')
