Question

我正在尝试构建一个可以显示附近地点的位置名称及其照片的应用。我正在使用Google Places API。

我想快速将photo_reference转换为照片网址。

目前，如果你进行附近的搜索，你会在附近的20个地点找回这个json（我刚刚粘贴了2个位置，因为json太长了）：

要获取照片网址，您必须为json中的20个photo_reference中的每一个调用以下内容 - 这些对Google服务器的调用需要花费大量时间才能返回，因为您单独呼叫服务器20次：< / p>

https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&photoreference=CmRdAAAAHcsAE2aiv5lIxLEo0c9xMUmH-chXoAeq6yrFPw5uy7LdppAMxBmg8_yvG9y9qaXqsH-IrcPsBD6QQvsfZnpml3U5zgh93nTbm5WONnYmutBSltIr9FwuK-awm8l1vyKeEhD9AqZpJwFLIWms2GeZGPR2GhSPp1JyAU_6_s1Im1_oH5tB4IjyXQ&key=API-KEY

每次调用都会返回与此类似的内容，即图像的实际网址 - 如果单击下面的链接，则会转到实际图片。

我认为这是一种非常低效的方式来获取地方照片的链接，我的其余API调用有时会在10秒后返回。有效的方法吗？
