Google 静态地图中显示编码路径的问题

Question

我已经对多边形的路径进行了编码。

当我在 https://developers.google.com/maps/documentation/utilities/polylineutility 中检查它时，它完美运行： Polygon in Google Devlopper Test

encoded path: wptdHtgeI@a@HaEHmCTkDDUVsAF{G@wD@o@~~~~~~Bq@@{CAuC?{D?_B?e@EsCe@aCoA{Ea@}AOm@vAgA|BcBr@i@nCs@hBe@~@UlFmAZI|Cs@nBc@FAf@K`@IAvDFF~~~~~~Bp@@|D~~~~~~BlC@tG~~~~~~BX@hG~~~~~~B`A~~~~~~BzC~~~~~~BfB~~~~~~Bx@~~~~~~B|D~~~~~~B^~~~~~~BtA@`D~~~~~~B`@~~~~~~B~~~~~~BG?B\?bE~~~~~~BrD@jJ@xDEvA~~~~~~Bt@?rA@|F?|E~~~~~~BRIBq@JC@k@Hm@H?~~~~~~BA~~~~~~B@Pq@\{Av@sBbA{ADk@Xi@Hi@G[GUIUGUIMC_EwBWCYEUC~~~~~~B?HiC|@LF@F}@BWNaDNsDc@YuABU@sADH_D~~~~~~BAYFB{@??

但是当我用静态地图尝试相同的代码时，我不起作用。

我在 PHP 中使用 urlencode 更改了路径：

拜托：我需要一个 PHP 而不是 js 的解决方案，并且仅适用于静态地图...

您的编码路径似乎有问题。在您的静态地图 API 请求中使用 Interactive Polyline Encoder Utility 中的 编码多段线 。

鉴于您的编码路径，

wptdHtgeI@a@HaEHmCTkDDUVsAF{G@wD@o@~~~~~~Bq@@{CAuC?{D?_B?e@EsCe@aCoA{Ea@}AOm@vAgA|BcBr@i@nCs@hBe@~@UlFmAZI|Cs@nBc@FAf@K`@IAvDFF~~~~~~Bp@@|D~~~~~~BlC@tG~~~~~~BX@hG~~~~~~B`A~~~~~~BzC~~~~~~BfB~~~~~~Bx@~~~~~~B|D~~~~~~B^~~~~~~BtA@`D~~~~~~B`@~~~~~~B~~~~~~BG?B\?bE~~~~~~BrD@jJ@xDEvA~~~~~~Bt@?rA@|F?|E~~~~~~BRIBq@JC@k@Hm@H?~~~~~~BA~~~~~~B@Pq@\{Av@sBbA{ADk@Xi@Hi@G[GUIUGUIMC_EwBWCYEUC~~~~~~B?HiC|@LF@F}@BWNaDNsDc@YuABU@sADH_D~~~~~~BAYFB{@??

您将获得来自 Interactive Polyline Encoder Utility 的以下编码折线，您可以在静态地图 API 请求中使用它：

wptdHtgeI@a@HaEHmCTkDDUVsAF{G@wD@o@?q@@{CAuC?{D?_B?e@EsCe@aCoA{Ea@}AOm@vAgA|BcBr@i@nCs@hBe@~@UlFmAZI|Cs@nBc@FAf@K`@IAvDFF?p@@|D?lC@tG?X@hG?`A?zC?fB?x@?|D?^?tA@`D?`@??G?B\?bE?rD@jJ@xDEvA?t@?rA@|F?|E?RIBq@JC@k@Hm@H??A?@Pq@\{Av@sBbA{ADk@Xi@Hi@G[GUIUGUIMC_EwBWCYEUC??HiC|@LF@F}@BWNaDNsDc@YuABU@sADH_D?AYFB{@??

您可以试试这个有效的 API 请求：

https://maps.googleapis.com/maps/api/staticmap?key=YOUR_API_KEY&center=48.109115,-1.670599&zoom=13&size=600x600&maptype=roadmap&path=fillcolor:0xAA000033%7Ccolor:0xFFFFFF00%7Cenc:wptdHtgeI@a@HaEHmCTkDDUVsAF{G@wD@o@?q@@{CAuC?{D?_B?e@EsCe@aCoA{Ea@}AOm@vAgA|BcBr@i@nCs@hBe@~@UlFmAZI|Cs@nBc@FAf@K`@IAvDFF?p@@|D?lC@tG?X@hG?`A?zC?fB?x@?|D?^?tA@`D?`@??G?B\?bE?rD@jJ@xDEvA?t@?rA@|F?|E?RIBq@JC@k@Hm@H??A?@Pq@\{Av@sBbA{ADk@Xi@Hi@G[GUIUGUIMC_EwBWCYEUC??HiC|@LF@F}@BWNaDNsDc@YuABU@sADH_D?AYFB{@??

注意：请在示例请求中提供您自己的 API 密钥。

希望对您有所帮助！
