如何在服務器產品上配置 Angular 代理？

Question

我正在使用 Angular 在我的前端應用程序構建中測試一種新方法，並且我想從瀏覽器網絡中隱藏 API url。 form example: to call login on api.url.dz/login i want to call front.url.dz/login on the front then redirecte this to api.url.dz/login. 這是我的 proxy.config.json 文件：

{
    "http://localhost:4200":{
        "target":"http://localhost:9999/",
        "secure":false,
        "changeOrigin": true,
        "logLevel":"debug",
        "pathRewrite": {"^/authenticate": "authenticate",
                        "^/authenticate-refresh": "authenticate-refresh",
                        "^/refresh-token": "refresh-token",
                        "^/auth-logout": "auth-logout"
                    }
                    }
}

這適用於本地主機，因為我使用以下命令啟動項目：

ng serve --proxy-config proxy.config.json

但在生產服務器中執行時：

ng build

它不起作用
這是產品服務器中的配置：

{
    "https://front.domaine.dz":{
        "target":"https://back.domaine.dz:9999",
        "secure":false,
        "changeOrigin": true,
        "logLevel":"debug",
        "pathRewrite": {"^/authenticate": "authenticate",
                        "^/authenticate-refresh": "authenticate-refresh",
                        "^/refresh-token": "refresh-token",
                        "^/auth-logout": "auth-logout"
                    }
                    }
}

我想知道在 ng build 命令中是否有使用代理選項執行的替代方法？

Angular 代理不適用於生產。

您可以通過在生產中使用代理配置運行ng serve來規避這種情況，但這是不好的做法。

您必須根據您的proxy.config.json配置您的 web 服務器（apache/nginx/other）以代理請求（如，使用相關指令獲得與您的proxy.config.json相同的行為）

例如，您可以將ProxyPass和ProxyPassReverse與 Apache 一起使用。
