Question

因此，在设置新的Freemium项目之后，我将示例代码从https://developer.here.com/documentation/maps/topics/routing.html复制粘贴到了新项目中，并且直到最近路由API神秘地开始拒绝我的API请求为止，它都可以正常工作：{{ 3}}

鉴于使用这些凭据的每个其他请求都可以正常工作，因此凭据似乎还可以。我是否缺少某些东西，或者这是他们的问题？

// Instantiate a map and platform object:
var platform = new H.service.Platform({
  'app_id': '4I898D4cYJAYrLryygIZ',

});
// Retrieve the target element for the map:
var targetElement = document.getElementById('map');

// Get the default map types from the platform object:

  'waypoint1': 'geo!52.5309916298853,13.3846220493377', // To retrieve the shape of the route we choose the route

// Define a callback function to process the routing response:

我做将那些密钥注册到正确的域btw，所以这不是问题。

免费增值用户需要在其请求中设置正确的HTTP Referer标头。检查此处日志，我们可以看到您正在使用：

referer = https://www.cs.drexel.edu/~nim28/CI102/Projects/Project-1/trucking-gps.php

但是，Delivery Portal中的引荐来源网址设置为“ cs.drexel.edu”（无www）

这就是为什么您会收到401错误的原因。因为app_id / app_code是正确且活动的，所以HTTP 401的唯一原因是错误的引荐来源网址。我们已经在本地确认将引荐来源网址设置为https://cs.drexel.edu/~nim28/CI102/Projects/Project-1/trucking-gps.php确实可行。

希望这会有所帮助！

Here-Maps路由API使用无效的凭据失败，但是其他Here-API继续使用完全相同的凭据工作
