网页无法到达反向代理服务器

【问题标题】：Web Page cannot reach reverse proxy server网页无法到达反向代理服务器

【问题描述】：

仅在本地 LAN 中具有反向代理的网页

我正在尝试创建一个 HTML 页面，该页面可以从我的网络上的任何位置访问，但也可以访问我的反向代理，该代理允许该网页访问本地服务器。

我使用的是 Mac 服务器，我可以从局域网上的任何位置从任何设备访问该网页。

我的网页以这种方式成功调用了互联网服务器：

var requestURL = "https://api.spark.io/v1/devices/" + deviceID + "/" + getFunc + "/?access_token=" + accessToken;
    $.getJSON(requestURL, function(json) {
        document.getElementById("range").innerHTML = json.result + "%";
        document.getElementById("myRange").value = json.result;
    });

我用于网页的服务器是 10.0.1.16，也可以在 server.local 访问。

我测试了这样调用服务器的网络应用程序：

  $.getJSON("http://127.0.0.1:8080/data_request?id=status&output_format=json&DeviceNum=3", function(data) {
      var found = data.Device_Num_3.states.filter(function(item) {
          return item.variable === 'CurrentSetpoint';
      });
      var currentTemp = found[0].value;
      document.getElementById("mainSetpoint").innerHTML = currentTemp;
      var found = data.Device_Num_3.states.filter(function(item) {
          return item.variable === 'CurrentTemperature';
      });
      var currentTemp = found[0].value;
      document.getElementById("mainActual").innerHTML = currentTemp;
  });

它有效，但仅当我在 Mac 服务器上加载网页时。网络上的任何其他设备都可以访问该网页，但不能访问反向代理服务器。

其中 127.0.0.1:8080 是反向代理的 IP 和端口。

显然我不明白这是如何工作的......

任何人都可以在这里引导我走向正确的方向吗？

我尝试在我的 Mac 服务器上设置反向代理，但我认为我还有另一个问题：

【问题讨论】：

    标签： javascript html reverse-proxy nat


    【解决方案1】：

    这可能是因为 127.0.0.1 是您在反向代理服务器上的环回地址。并且只能在相关机器上使用该地址。

    尝试使用反向代理服务器的 LAN IP（可能是 10.0.1.x）。 我猜反向代理服务器运行在 Mac 服务器上。

    【讨论】：

    • 我确实尝试过，但设置时出错...我将编辑我的原始帖子
    • 我对 Mac 一无所知，但错误可能是因为该端口已被另一台服务器使用。 netstat -nap |grep 8080 返回什么？
    • 正如我所说，我不知道如何使用 Mac，但这可能应该以 root 身份运行。如果它不起作用，则 netstat 命令不存在或具有与我猜的 Linux 不同的参数。
    • 我用 :server:~ admin$ sudo lsof -i -P | 的输出编辑了我的帖子grep -i "听"
    • 您已经有一个节点进程在监听 8080 端口，请查看转储的最后一行
