Question

我正在尝试访问Rap Stats的数据：http://rapstats.herokuapp.com/

在检查代码之后，我确定代码正在调用以获取用于创建图形的数据（http://rapstats.herokuapp.com/articles/ngram_calculator?utf8=%E2%9C%93&q=Jordan%2C+Pippen），但是我似乎无法访问它，因为它引发了500错误。

如何才能访问此来源需要做什么？这是饼干的问题吗？

Answer 1

您需要设置标题"X-Requested-With":"XMLHttpRequest"。然后它会工作。很多人忽略了标题，但它们很重要。

示例：

>>> url = "http://rapstats.herokuapp.com/articles/ngram_calculator?utf8=%E2%9C%93&q=east+side%2C+west+side"
>>> headers = {"X-Requested-With":"XMLHttpRequest"}
>>> requests.get(url,headers=headers).text
