AWS弹性负载均衡器未将HTTP头转发到EC2实例

Question

我目前在Amazon Elastic Beanstalk上运行一个Python Flask应用程序。当我测试应用程序时，本地一切正常（我使用Postman发送GET和POST请求）。然而，在AWS上，它不起作用，因为到达我的EC2实例（负载均衡器后面）的请求不包括Authorization头。看起来负载均衡器会剥离掉这个头。这里有一个比较，显示了本地和Elastic Beanstalk上打印出的标头的区别。 本地： [2017-07-04 13:18:14,650] [INFO] [common.decorators] Headers = Host: localhost:5000 Connection: keep-alive Content-Length: 151 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Cache-Control: no-cache Origin: chrome-extension://fhbjgbiflinjbdggehcddcbncdddomop Content-Type: application/json Authorization: Bearer ad9fd4d9-6ce6-497b-855a-dcebebdad65b Postman-Token: xxxxx Accept: */* Accept-Encoding: gzip, deflate, br Accept-Language: en-US,en;q=0.8 Elastic Beanstalk: [2017-07-04 17:27:03,813] [DEBUG] [common.decorators] Headers = Accept-Language: en-US,en;q=0.8 Accept: */* Host: dev.onetext.com X-Forwarded-For: 66.30.13.108 Content-Type: application/json Postman-Token: xxxxx Connection: keep-alive Accept-Encoding: gzip, deflate, sdch, br X-Forwarded-Proto: https Cache-Control: no-cache X-Forwarded-Port: 443 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36

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”文件夹下添加一个新文件并添加以下内容来解决这个问题： files: "/etc/httpd/conf.d/wsgihacks.conf": mode: "000644" owner: root group: root content: | WSGIPassAuthorization On

AWS不接受标题中的下划线(_)，而我们可以使用短横线(-)。因此，请从标题变量中删除下划线underscores。例如： header_var_val =“some value”请替换为

headervarval = "some value"

对我来说它有效
