AWS Elastic Load Balancer不将HTTP标头转发到EC2实例

我目前正在Amazon Elastic Beanstalk上运行Python Flask应用程序。当我测试应用程序时,它在本地工作正常(我使用Postman发送GET和POST请求)。但是,在AWS上,它不起作用,因为到达我的EC2实例(在负载均衡器后面)的请求不包含授权标头。似乎负载平衡器剥离了标头。我在这里做错了吗?

这是我在本地和Elastic Beanstalk上打印标题时所得到的对比。

感谢@notionquest添加的评论,我在https://forums.aws.amazon.com/thread.jspa?messageID=729128

找到了解决方案

我通过在.ebextensions文件夹下添加一个包含以下内容的新文件解决了这个问题:

files: "/etc/httpd/conf.d/wsgihacks.conf": mode: "000644" owner: root group: root content: | WSGIPassAuthorization On

答案 1 :(得分:1)

AWS在标题中不接受(_)的非下划线,尽管我们可以使用(-),所以从标题变量中删除下划线 ,例如:     header_var_val =“某些值” 替换为

headervarval = "some value"

对我有用
