NGINX API 代理返回 400 Bad Rquest

Question

我正在尝试按照以下步骤将 NGINX 配置为 API 代理NGINX 博客但我得到的是400 Bad Request当连接到该示例的模拟（和工作）API时。

对此有什么想法吗？

api_gateway.conf

log_format api_main '$remote_addr - $remote_user [$time_local] "$request"'
                    '$status $body_bytes_sent "$http_referer" "$http_user_agent"'
                    '"$http_x_forwarded_for" "$api_name"';

include api_backends.conf;
#include api_keys.conf;

server {
    set $api_name -; # Start with an undefined API name, each API will update this value
    access_log /var/log/nginx/api_access.log api_main; # Each API may also log to a separate file

    listen 443 ssl;
    server_name <my-ip-address>; #have put my ip address where nginx installed

    # TLS config
    ssl_certificate      /etc/nginx/certs/test-bundle.crt;
    ssl_certificate_key  /etc/nginx/certs/test.key;
    ssl_session_cache    shared:SSL:10m;
    ssl_session_timeout  5m;
    ssl_ciphers          HIGH:!aNULL:!MD5;
    ssl_protocols        TLSv1.1 TLSv1.2;

    # API definitions, one per file
    include api_conf.d/*.conf;

    # Error responses

    proxy_intercept_errors on;     # Do not send backend errors to the client
