nginx已配置header传递,但是转发下还是丢失头信息(header)
查找原因后得知是nginx在转发请求时会默认忽略带有"_"下划线的头信息
配置underscores_in_headers on;即可;underscores_in_headers默认是off;
参考nginx官网说明:http://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers
Syntax: underscores_in_headers on | off;
Default:
underscores_in_headers off;
Context: http, server
