Python - 使用请求发送帖子消息

Question

我使用 Postman 向 Jetstar 网站发送原始请求以获取航班详细信息。我想使用 python 脚本使用 requests 库做同样的事情，但我无法得到正确的响应。

这是我在 Postman 中所做的：

还有一个我用来发送帖子请求的简单脚本：

import requests
files = {'file': open('PostContent.txt', 'rb')}
if __name__ == "__name__"):
    url = "http://www.jetstar.com/"
    r = requests.post(url, files = files)
    print(r.text)

当我运行 python 脚本时，我总是得到欢迎页面而不是航班详细信息。我不确定是什么错误？

注意：当我搜索航班时，PostContent.txt 包含原始文本形式的数据。

我在搜索特定航班日期时使用 Chrome 开发工具捕获 POST 请求。它是标题中的表单数据。

Answer 1

尝试使用字典而不是 FILE。 FILE 应该用于发布 FILE，而不是 FORM-ENCODED 帖子，这可能是网站所期望的。

payload = {
   'DropDownListCurrency': 'SGD'
}
r = requests.post("http://httpbin.org/post", data=payload)

您使用的密钥 file 对于此类请求是错误的。您的示例代码也不起作用！只需在此处粘贴工作代码...

import requests
import logging

logging.basicConfig(level=logging.DEBUG)

payload = {"__EVENTTARGET":"",
