Question

通过这个主题的所有帖子阅读并尝试了所有组合： 1.在进行google places API调用时使用了android键（ 2.切换到浏览器键 3.后来尝试使用服务器密钥。 4.重新生成密钥并尝试组合1-3。

什么都没有用!!清单文件中Mapv2 API的密钥是android密钥。这个应用程序工作正常，直到我创建了一个新项目并使用新项目列出了我的包。我为这个包重新创建了新的android密钥。旧密钥仍在那里，但有一个不同的项目。我没有删除旧项目但删除了它下面的所有密钥。所以现在我在新项目下有了新的android键，浏览器。我做错了吗？

我收到错误消息为＆＃34;提供的API密钥无效＆＃34; ... 当我使用浏览器密钥从浏览器进行此调用时，它正在工作。不是来自我的Android应用程序。有小费吗？。

请参阅以下代码： -

final String PLACES_API_BASE = "https://maps.googleapis.com/maps/api/place/nearbysearch";
final String OUT_JSON = "/json";
final String KEY=<browser-key>
final String SENSOR="false";
StringBuilder querystring = new StringBuilder(PLACES_API_BASE+OUT_JSON);
try{
querystring.append("?sensor="+SENSOR+"&key="+KEY);
String localquery="&location=37.316318,-122.005916&radius=500&name=traderjoe";
                querystring.append(URLEncoder.encode(localquery, "UTF-8"));
                URL url = new URL(querystring.toString());
                 HttpURLConnection connection = (HttpURLConnection)url.openConnection();
         connection.setRequestMethod("GET");
           String line;
   StringBuilder builder = new StringBuilder();
   BufferedReader reader = new BufferedReader(
     new InputStreamReader(connection.getInputStream()));
   while((line = reader.readLine()) != null) {
    builder.append(line);
}
       System.out.println("JSON BUILDER INPUT FROM GOOGLE PLACES QUERY="+builder.toString());

这是我收到错误消息的地方： - 提供的APi密钥是invaild

以下是我在CSharp中使用googlePlaceApi的代码

public List<GooglePlace> GoogleApiPlace(Coordinate startCoordinate)
    {
        List<GooglePlace> ListOfPlace = new List<GooglePlace> ();

        string apiURL = "https://maps.googleapis.com/maps/api/place/nearbysearch/xml?location=";
        string apiKey = "myKey";

        string linkApi = apiURL + startCoordinate.Latitude.ToString ().Replace (',', '.') + "," + startCoordinate.Longitude.ToString ().Replace (',', '.') + "&radius=1000&sensor=true&types=establishment&key=" + apiKey;

        var request = HttpWebRequest.Create(linkApi);
        request.ContentType = "application/xml";
        request.Method = "GET";

        try
        {
            using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
            {
                if (response.StatusCode != HttpStatusCode.OK)
                {
                    Console.Out.WriteLine("Error fetching data, Server returned status code {0}", response.StatusCode);
                }
                using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                {
                    var content = reader.ReadToEnd();
                    if (string.IsNullOrWhiteSpace(content))
                    {
                        Console.Out.WriteLine("Responsed contained empty body...");
                    }
                    else
                    {
                        XmlDocument document = new XmlDocument();
                        document.LoadXml(content);
                        Console.Out.WriteLine(content);
                        XmlNodeList nodeList = document.GetElementsByTagName("result");

                        foreach (XmlNode docNode in nodeList)
                        {
                            string tot = ((XmlElement)docNode).GetElementsByTagName("lat")[0].InnerText;
                            GooglePlace place = new GooglePlace()
                            {
                                Location = new Location()
                                {
                                    Coordinate = new Coordinate()
                                    {
                                        Latitude = Double.Parse(((XmlElement)docNode).GetElementsByTagName("lat")[0].InnerText, CultureInfo.InvariantCulture),
                                        Longitude = Double.Parse(((XmlElement)docNode).GetElementsByTagName("lng")[0].InnerText, CultureInfo.InvariantCulture)
                                    }
                                },
                                Name = docNode.ChildNodes.Item(0).InnerText.TrimEnd().TrimStart(),
                                Vicinity = docNode.ChildNodes.Item(1).InnerText.TrimEnd().TrimStart()
                            };
                            ListOfPlace.Add(place);
                        }
                    }
                }
            }
        }
        catch
        {
            //TODO : Exception
        }

        return ListOfPlace;
    }

Api Key就在这里 enter image description here

关注these instructions in detail.请注意，您需要创建Android Key (not Server key)

Answer 4

您必须在Google控制台中启用“Google Places API for Android”而非“Google Places API for web services”。如果您使用Android中的地方网络服务，则必须启用“Google商家信息系统API for Web Services”。密钥将是一个浏览器密钥。

e.g。 https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&types=food&name=cruise&key=API_KEY

Google Places API返回提供的API密钥无效
