我有一个BE webservice，它返回一个wsdl，当我直接访问它时，它没有问题，但是当我通过NginX访问它时，需要更长的时间来加载（5-6分钟）。当我分析这一点时，似乎虽然服务器正在向客户端发送所有数据，但是服务器/ NginX没有关闭连接，因此浏览器无法呈现内容。后端服务器始终向NginX发送完整响应，但NginX不会将所有内容发送到客户端。看来NginX还在等待更多？以下是一些卷曲推文。
直接致电BE （请求和响应标头）
> GET /services/echo?wsdl HTTP/1.1
> Host: 172.30.16.47:8280
> User-Agent: curl/7.51.0
> Accept: */*
>
< HTTP/1.1 200 OK
< Content-Type: text/xml
< Date: Wed, 11 Jan 2017 08:32:35 GMT

通过Nginx（请求和响应）调用

以下是来自NginX的调试日志。

我尝试了什么
我尝试删除Connection Keep-alive属性。但没有运气。 已禁用BE服务器端连接保持活动状态。
对我来说没有任何作用。有谁有想法在这里发生什么？
答案 0 :(得分：1)
我解决了问题。看来我的BE服务器默认发送非分块响应（使用HTTP 1.0）。因此强制BE使用HTTP 1.1解决了这个问题。我在Nginx中使用了以下属性。
proxy_http_version 1.1;
