放置详细信息请求失败
我有一个小的java应用程序,给定一个谷歌地方的参考列表,必须取回每个所述谷歌地点的Id(长话短说,我们存储的地方,而不是他们的ID的引用,只有现在才意识到,引用每个地方都不是唯一的)。
我的应用程序完美适用于列表中大约95%的位置,但对于某些记录而言失败时会显示“NOT_FOUND”状态码。 某些调查显示,这些特定地点的地点参考(如果与https://maps.googleapis.com/maps/api/place/details/json?sensor=false&key=myApiKey前缀结合使用)大约2个字符太长一个URL。 最后几个字符被截断。
我最初的想法是,我只会向Google Places API发出一个POST请求,但是在将它发送到POST请求时,我会从Google服务器获取“REQUEST_DENIED”状态代码。
反正有,或者这只是谷歌地方API的一个新出现的错误(现在的地方数已经把参考推得太久了?)。
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(工作为95%)代码的样子:
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”邮政代码的样子:
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;
}

提前致谢!
您正在将正文中的请求参数发送出去,而API不支持这些参数。 有关GET的一个很好的答案,并请求params:
带请求正文的HTTP GET
以下代码适用于放置详细信息请求:
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);
}
