使用nginx作为反向代理的API网关

Question

我在Docker容器中有两项服务（WMS和WFS）。 我想将nginx用作网关，并且具有如下所示的配置-现在无法正常工作。

我应该使用set $upstream backend_server还是proxy_pass baskend_server？

如何为以下情况进行工作配置？

第一种情况

网关URL

http://project_test.local/wms?
SERVICE=WMS&
REQUEST=GetCapabilities&
VERSION=1.3.0

URL代理

http://wms_server:8080/project_test/service?
SERVICE=WMS&
REQUEST=GetCapabilities&
VERSION=1.3.0

第二种情况

网关URL

http://project_test.local/wfs?
SERVICE=WFS&
REQUEST=GetCapabilities&
VERSION=2.0.0

URL代理

http://wfs_server:8080/ows?
MAP=project_test&
SERVICE=WFS&
REQUEST=GetCapabilities&
VERSION=2.0.0
