通过nginx代理后

location / {

proxy_http_version 1.1;

proxy_pass https://api.mch.weixin.qq.com;

#proxy_redirect off;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header Host api.mch.weixin.qq.com;

proxy_set_header X-Forwarded-Proto $scheme;

#proxy_set_header X-Forwarded-proto https;

proxy_pass_request_headers on;

proxy_set_header $http_authorization $http_authorization;

proxy_set_header Aauthorization $http_authorization;

proxy_set_header Cookie $http_cookie;

proxy_buffering off;

proxy_read_timeout 3000;

proxy_send_timeout 3000;

}

请求接口报错{"code":"SIGN_ERROR","message":"Http头Authorization值格式错误，请参考《微信支付商户REST API签名规则》"}，改成微信域名就正常了
