我有一个小的Java应用程序,给出谷歌地方的参考列表,必须取回每个谷歌地方的Id(长话短说,我们存储地方的参考而不是他们的Id,只有现在意识到每个地方的参考不是唯一的。)
我的应用程序适用于列表中大约95%的位置,但是对于某些记录而言失败并带有“NOT_FOUND”状态代码。一些调查显示,这些特定地点的地点参考(当与https://maps.googleapis.com/maps/api/place/details/json?sensor=false&key=myApiKey前缀结合使用时)对于URL来说太长2个字符。最后几个字符被截断了。
我最初的想法是,我只是向google places API发出POST请求,但是当我将这些请求作为POST请求发送时,我将从google服务器返回“REQUEST_DENIED”状态代码。
有没有相关的,或者这只是谷歌地方API的一个突现错误(现在地方的数量推动了参考太长了?)。
我还应该注意,失败的地方最近都是由我们的应用程序添加的。
这是我目前的(95%)代码的代码:
public static JSONObject getPlaceInfo(String reference) throws Exception
{
URL places = new URL("https://maps.googleapis.com/maps/api/place/details/json?sensor=false&key="+apiKey+"&reference="+reference);
URLConnection con = places.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
StringBuffer input = new StringBuffer();
String inputLine;
while ((inputLine = in.readLine()) != null)
input.append(inputLine);
in.close();
JSONObject response = (JSONObject) JSONSerializer.toJSON(input.toString());
return response;
}
这就是我的“ACCESS_DENIED”邮政编码:
public static JSONObject getPlaceInfo(String reference) throws Exception
{
String data = URLEncoder.encode("sensor", "UTF-8") + "=" + URLEncoder.encode("true", "UTF-8");
data += "&" + URLEncoder.encode("key", "UTF-8") + "=" + URLEncoder.encode(apiKey, "UTF-8");
data += "&" + URLEncoder.encode("reference", "UTF-8") + "=" + URLEncoder.encode(reference, "UTF-8");
URL places = new URL("https://maps.googleapis.com/maps/api/place/details/json");
URLConnection con = places.openConnection();
con.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(con.getOutputStream());
wr.write(data);
wr.flush();
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
StringBuffer input = new StringBuffer();
String inputLine;
while ((inputLine = in.readLine()) != null)
input.append(inputLine);
in.close();
JSONObject response = (JSONObject) JSONSerializer.toJSON(input.toString());
return response;
}

您在身体中发送请求参数,但API不支持。关于GET和请求参数的答案很好:
以下代码适用于广告详细信息请求:
private static final String PLACES_API_BASE = "https://maps.googleapis.com/maps/api/place";
private static final String TYPE_DETAILS = "/details";
private static final String OUT_JSON = "/json";
HttpURLConnection conn = null;
StringBuilder jsonResults = new StringBuilder();
try {
StringBuilder sb = new StringBuilder(PLACES_API_BASE);
sb.append(TYPE_DETAILS);
sb.append(OUT_JSON);
sb.append("?sensor=false");
sb.append("&key=" + API_KEY);
sb.append("&reference=" + URLEncoder.encode(reference, "utf8"));
URL url = new URL(sb.toString());
conn = (HttpURLConnection) url.openConnection();
InputStreamReader in = new InputStreamReader(conn.getInputStream());
// Load the results into a StringBuilder
int read;
char[] buff = new char[1024];
while ((read = in.read(buff)) != -1) {
jsonResults.append(buff, 0, read);
}
} catch (MalformedURLException e) {
return null;
} catch (IOException e) {
return null;
} finally {
if (conn != null) {
conn.disconnect();
}
}
try {
// Create a JSON object hierarchy from the results
JSONObject jsonObj = new JSONObject(jsonResults.toString()).getJSONObject("result");
jsonObj.getString("name");
} catch (JSONException e) {
Log.e(LOG_TAG, "Error processing JSON results", e);
}
