【中文标题】如何以编程方式重复表单 POST 请求【英文标题】：How do I repeat the form POST request programmatically 【发布时间】：2015-05-30 11:51:16 【问题描述】：当我访问该网站时http://www.jetstar.com/au/en/home
填写表格然后提交。
它将发送一个 POST 请求，然后将我重定向到显示票价页面（html）的新页面。
我可以在第二个 GET 响应中得到预期的结果
但是，当我尝试使用 Ruby 或 Charles
重复 POST 请求时我会得到 302 Found 错误。
我不明白。

【问题讨论】：
302 不是错误代码，它是 HTTP 重定向。服务器将您重定向到哪里？这可能会提供线索。 【参考方案1】：这很可能是因为CSRF verification，站点用户 CSRF 验证请求以确保表单提交来自同一站点。
在您的情况下，您尝试从其他来源提交表单，因此验证失败。
如果您想执行上述操作，我会使用 capybara 之类的库进行屏幕抓取
