我正在尝试实施 amp-analytics - 没有 Google AMP 页面的供应商，用于网页浏览。我使用 URL 参数将指标发送到页面以定义我要跟踪的内容，并且此 URL 可以正常工作：

https://tru.am/page_views?clientID=1182&version=13&canonical=https%3A%2F%2Fs3.amazonaws.com%2Ftru-am-dev%2Fpromote%2Ftest.amp.6.analytics.html&ogURL=https%3A%2F%2Fs3.amazonaws.com%2Ftru-am-dev%2Fpromote%2Ftest.amp.6.analytics.html&referrer=TBA&title=test%20page%20for%20AMP%20analytics&image=http%3A%2F%2Fwww.trueanthem.com%2Fwp-content%2Fuploads%2F2016%2F03%2Fabout_bottom.jpg&callback=eqwest_1502748414821

我收到一条回复，说明数据已收集。

现在，当我在 Google AMP 页面中实现它时，当它调用我的 URL 并发送参数以收集数据时，我收到由 Google transport.js 库触发的错误代码 404，第 84 行。

transport.js：与问题相符的是：

const result = win.navigator.sendBeacon(request, '');

这是来自 transport.js 的上下文：

...
/**
       * @param {!Window} win
       * @param {string} request
       * @return {boolean} True if this browser supports navigator.sendBeacon.
       */
      static sendRequestUsingBeacon(win, request) {
        if (!win.navigator.sendBeacon) {
          return false;
        }
        const result = win.navigator.sendBeacon(request, '');
        if (result) {
          dev().fine(TAG_, 'Sent beacon request', request);
        }
        return result;
      }
...

我正在使用的分析代码在 AMP 页面中是这样的：

<amp-analytics>
      <script type="application/json">
      {
        "requests": {
          "pageview": "https://tru.am/page_views?clientID=${clientId}&version=${version}&canonical=${canonical}&ogURL=${ogURL}&referrer=${referrer}&title=${title}&image=${image}&callback=${callback}"
        },
        "triggers": {
          "trackPageview": {
            "on": "visible",
            "request": "pageview",
            "vars": {
              "eventId": "pageview",
              "clientId": "1182",
              "version" : "13",
              "canonical": "https://s3.amazonaws.com/tru-am-dev/promote/test.amp.6.analytics.html",
              "ogURL": "https://s3.amazonaws.com/tru-am-dev/promote/test.amp.6.analytics.html",
              "referrer": "TBA",
              "title": "test page for AMP analytics",
              "image": "http://www.trueanthem.com/wp-content/uploads/2016/03/about_bottom.jpg",
              "callback": "eqwest_1502748414821"
            }
          }
        }
      }
      </script>
      </amp-analytics>

我在页面中没有收到其他错误代码，并且#development=1在 URL 中使用我AMP validation successful在浏览器的控制台中收到消息。

404错误的详细信息：

Request URL:https://tru.am/page_views?clientID=1182&version=13&canonical=https%3A%2F%2Fs3.amazonaws.com%2Ftru-am-dev%2Fpromote%2Ftest.amp.6.analytics.html&ogURL=https%3A%2F%2Fs3.amazonaws.com%2Ftru-am-dev%2Fpromote%2Ftest.amp.6.analytics.html&referrer=TBA&title=test%20page%20for%20AMP%20analytics&image=http%3A%2F%2Fwww.trueanthem.com%2Fwp-content%2Fuploads%2F2016%2F03%2Fabout_bottom.jpg&callback=eqwest_1502748414821
Request Method:POST
Status Code:404 
Remote Address:104.25.163.34:443
Referrer Policy:no-referrer-when-downgrade

那么，如果相同的 URL 在浏览器中有效但在 Google transport.js 库中失败（错误代码 404），为什么？

问题是收集分析信号的页面 (//tru.am/page_views) 不接受 POST 请求，只接受 GET 请求。Google 以 POST 形式发送数据，然后生成 404 错误。
