如何获取图片的网址或从photo_reference下载图片

【问题讨论】：

您好，您是否收到错误消息，到目前为止您尝试了什么，您是否启用了 API 并获取了 API KEY？

可以使用Place Photos服务获取photo_reference字符串对应的图片。

示例请求：

https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&photoreference=CnRtAAAATLZNl354RwP_9UKbQ_5Psy40texXePv4oAlgP4qNEkdIrkyse7rPXYGd9D_Uj1rVsQdWT4oRz4QrYAJNpFX7rzqqMlZw2h2E2y5IKMUZ7ouD_SlcHxYq1yL4KbKUv3qtWgTK0A6QbGh87GB3sscrHRIQiG2RrmU_jF4tENr9wGS_YxoUSSDrYjWmrNfeEHSGSc3FyhNLlBU&key=YOUR_API_KEY

对于 swift 中的 iOS，您可以使用等效的 Place Photos 服务，使用 placeID 代替。见示例代码：

// Specify the place data types to return (in this case, just photos).
let fields: GMSPlaceField = GMSPlaceField(rawValue: UInt(GMSPlaceField.photos.rawValue))!

placesClient?.fetchPlace(fromPlaceID: "INSERT_PLACE_ID_HERE",
                         placeFields: fields,
                         sessionToken: nil, callback: {
  (place: GMSPlace?, error: Error?) in
  if let error = error {
    print("An error occurred: \(error.localizedDescription)")
    return
  }
  if let place = place {
    // Get the metadata for the first photo in the place photo metadata list.
    let photoMetadata: GMSPlacePhotoMetadata = place.photos![0]

    // Call loadPlacePhoto to display the bitmap and attribution.
    self.placesClient?.loadPlacePhoto(photoMetadata, callback: { (photo, error) -> Void in
      if let error = error {
        // TODO: Handle the error.
        print("Error loading photo metadata: \(error.localizedDescription)")
        return
      } else {
        // Display the first image and its attributions.
        self.imageView?.image = photo;
        self.lblText?.attributedText = photoMetadata.attributions;
      }
    })
  }
})

请注意，下载从 API 返回的图像会违反 Google 的 ToS。见相关Storing of photoreferences which are returned with place-details

希望这会有所帮助！
