我正在使用谷歌静态地图API在我的Angularjs应用程序中绘制谷歌地图图像。
它适用于低数量的地图坐标。但是如果有大量的地图坐标那么它就不是绘制地图图像。
例如以下将为低坐标数绘制图像但如果我增加该尺寸则不会绘制。
修改: - 我收到此Google地图图片网址的错误

您应该检查响应标头以找出静态地图请求的错误。
Google Static Maps API可能会在出现问题时发出错误或警告。如果您发现地图上缺少某些东西,您应该特别检查警告。在启动新应用程序之前检查警告也是一个好主意。请注意,警告可能不会立即显现,因为它们出现在HTTP标头中。

X-Staticmap-API-Warning
标题将包含有关错误或警告的说明。正如我在文档中看到的那样,地理编码位置的数量或折线顶点的数量存在一定的限制(15)。

我希望此信息可能有助于解决您的问题。

示例中的静态地图网址太长。它包含16187个符号。 Static Maps API将网址的最大长度限制为8192 characters。示例网址出错
如果您需要这么长的路径,则应按照
中的描述实施编码折线计算https://developers.google.com/maps/documentation/utilities/polylinealgorithm
并将其应用于您的网址。
我创建了一个简单的JavaScript代码,可以将坐标转换为编码折线。你可以在https://jsfiddle.net/xomena/tqv2zsq0/上看到它。编码折线有3064个字符,在允许的限制范围内。
现在您可以在URL中使用它,如此代码段所示(运行它以查看结果)

还有一条警告信息,您可以在浏览器网络控制台中查看,正如我在答案的第一部分中所述。
所以警告说
x-staticmap-api-warning: Failed to fetch image url http://192.168.1.194/public/images/g-pin-icon.png
Google无法获取您的自定义图标,因为它不是公开的,192.168.1.194是您的内部IP地址。您必须在公共可用主机上发布图标,以避免出现此警告消息。
