Question

我可以为此功能提供的最大起源数和目的地数是多少？或者更好：我可能要求的最大起始目的地组合数是多少？

现在我有33个起点和3个目的地 - 它正在运作。至于我再输入一个目的地 - 发生错误。它说像

Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\googlemaps\client.py", line 223, in _get
    result = self._get_body(resp)
  File "C:\Python34\lib\site-packages\googlemaps\client.py", line 242, in _get_body
    raise googlemaps.exceptions._RetriableRequest()
googlemaps.exceptions._RetriableRequest

During handling of the above exception, another exception occurred:

我有12次这样的行，最后

    raise googlemaps.exceptions.Timeout()
googlemaps.exceptions.Timeout

很高兴得到你的帮助！顺便说一句：我检查了额外的地址 - 这不会导致问题。它必须是地址的数量。但是我想就此获得专业意见......

谢谢!!!

来自Google Maps Distance Matrix API Usage Limits的文档：

发送到Google Maps Distance Matrix API的每个查询都受到允许元素数量的限制，其中原始数量乘以目标数量来定义元素数量。

Google Maps Distance Matrix API具有以下限制：

标准使用限制
  标准API的用户：

每天2,500个免费元素
每个查询100个元素
每10秒100个元素

当您提交维度33 x 3矩阵时，您只有99个元素，这些元素在免费服务等级的限制范围内。但是当你添加一个目的地（给你一个尺寸为34 x 3或33 x 4的矩阵）时，你超过100，因此错误。

您的选择包括选择高级服务，每次查询最多可提供625个元素，或以某种方式减少输入矩阵的大小。
