【问题描述】：

[

我正在尝试抓取此网站https://www.kickstarter.com/projects/818583073/dies-irae-day-of-wrath-rated-r/，当我向其 API 发送帖子请求时，它只返回响应 400 和空内容。

这是我的代码。

400
''

【问题讨论】：

x-csrf-token 标头对于每个请求可能必须不同...

【参考方案1】：

您已在标题中将内容类型设置为 json

把它改成'Content-Type':'text/html'就可以了

【讨论】：

它只返回这个 'errors': ['message': 'No query string was present']

@MalikIbrahim 现在错误的请求错误已解决。您必须使用查询调试并准备适当的有效负载，然后重试。您可能需要查看此特定 API 的 API 文档

你能帮我吗？我试过了，但没有找到。
