Question

我正在尝试通过python flask服务器在Google Maps Places API上进行API调用。请找到示例代码：

response = requests.get(
        'https://maps.googleapis.com/maps/api/place/nearbysearch/json?' + urlencode(
            {'location': location, 'rankby': 'prominence','types' : 'tourist_attraction' , 'key': gmaps_key, 'radius': 6000}))
    # Read response as json
    resp_address = response.json()
    if resp_address['status'] == 'OK':
        resp_address = resp_address['results']

        places_dictionary = {}

到目前为止，当在终端上独立测试时，此代码可以正常工作。但是在本地主机5000上运行时，API调用失败并导致以下错误：

（环境：Python 3.6 虚拟环境：无业游民烧瓶服务器）

在处理上述异常期间，发生了另一个异常：

试图检查它谷歌地图的URL，它可以在浏览器中工作，但通过本地主机执行它以某种方式失败。（此外，我的密钥限制仍然是无限的并且没有消耗）。

无法建立新的连接：[Errno -3]名称解析暂时失败，
