通常情况下，API管理分析可以通过客户端IP地址来确定地理位置。如果分析显示地理位置始终为“其他”，则可能是客户端IP地址无法正确解析。要解决此问题，可以尝试将API管理的设置中“代理服务器”选项更改为“在客户端侧解析IP地址”，这样可以保留原始客户端IP地址。示例代码如下：

{
    "properties": {
        "proxy": {
            "forward-request": {
                "to": "backend"
            },
            "set-backend-service": {
                "base-url": "https://contoso.com/api/services/"
            },
            "backend-service": {
                "url": "https://contoso.com/api/services/",
                "forward-headers": [
                    "Ocp-Apim-Subscription-Key"
                ],
                "forward-query-strings": true
            },
            "add-context-parameters": {
                "parameters": {
                    "client-ip-address": {
                        "location": "client",
                        "value": "@(context.Request.MatchedParameters["c-ip"])",
                        "resolver": {
                            "name": "CloudResolver",
                            "arguments": {
                                "fields": {
                                    "locality": "city",
                                    "region": "region",
                                    "country": "countryCode"
                                }
                            }
                        },
                        "protocols": "http"
                    }
                }
            }
        }
    }
}
