Trying to add an event to google places - google-maps

Question

I am trying to use the Google Place Actions API, specifically the events and I cannot get a valid post for the life of me.
Here is the URL I am using:
https://maps.googleapis.com/maps/api/place/event/add/json?sensor=false&key=placesApiKey&duration=26000&reference=CjQwAAAAv4TTQ3ySXiGhOElWFNAQ-roLOfgwo215yRTk1Bmhg0jSJ-sAdz9nHgNgnGBAmqP7EhC7K0AjTfFcZgCUh68c2yNtGhRkmynXvE5d4XA5ZfyBqAxlNdsAIg&summary=this is going to be something fun
The reference is to Tempe, AZ. I keep getting a 404 back saying that it is an illegal request. Any help would be great! I really don't know what I am doing wrong.
I have tried three different ways both with the same results:
HttpClient client = new HttpClient();
client.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler());
String url = "https://maps.googleapis.com/maps/api/place/event/add/json?sensor=false&key=" + googlePlacesAPIKey;
PostMethod post = new PostMethod(url);
NameValuePair[] data = {
new NameValuePair("duration", Long.toString(duration)),
new NameValuePair("reference", reference),
new NameValuePair("summary", summary)
};
post.setRequestBody(data);
and
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("https://maps.googleapis.com/maps/api/place/event/add/json?sensor=false&key=" + googlePlacesAPIKey);
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("duration", Long.toString(duration)));
nameValuePairs.add(new BasicNameValuePair("reference", reference));
nameValuePairs.add(new BasicNameValuePair("summary", summary));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
}
and
URL url = new URL("https://maps.googleapis.com/maps/api/place/event/add/json?sensor=false&key="+googlePlacesAPIKey+"&duration="+duration+"&reference="+reference+"&summary="+summary);
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestMethod("POST");
OutputStreamWriter out = new OutputStreamWriter( httpCon.getOutputStream());
System.out.println(httpCon.getResponseCode());
System.out.println(httpCon.getResponseMessage()); out.close();
and
HttpPost post = new HttpPost("https://maps.googleapis.com/maps/api/place/event/add/json?sensor=false&key=" + googlePlacesAPIKey);
post.setHeader("Content-type", "application/json");
JSONObject object = new JSONObject();
object.put("duration", Long.toString(duration));
object.put("reference", reference);
object.put("summary", summary);
String message = object.toString();
post.setEntity(new StringEntity(message));
HttpResponse response = client.execute(post);
Here is the link to the API for those that are curious:

Answer 1

In python, you can do like this:
#!/usr/bin/python
# coding: utf8
import sys
import urllib
parameters = urllib.urlencode({
'key' : "YOUR_API_KEY",
'sensor' : 'false'
})
url = "https://maps.googleapis.com/maps/api/place/event/add/json?%s" % (parameters)
#The reference
reference = "CoQBdgAAAN4u...YKmgQ"
#Add event
postdata = '''
{
"duration": 86400,
"language": "ja",
"reference": "%s",
"summary": "Event Name!",
"url" : "http://hogehoge.com/test_page"
}
''' % (reference)
f = urllib.urlopen(url, postdata)
print f.read()

Ok, I'm not good for Java though, I created an example code for Android Java.
[MainActivity.java]
package com.example.placeseventtest;
import org.json.JSONArray;
import org.json.JSONObject;
import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends Activity {
private final String API_KEY = "YOUR_API_KEY";
private PlacesHTTP myUtil;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView resTxtView = (TextView) findViewById(R.id.responseText);
myUtil = new PlacesHTTP(API_KEY, resTxtView);
Button currentPosBtn = (Button) this.findViewById(R.id.currentPosBtn);
currentPosBtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
JSONObject params = new JSONObject();
JSONObject location = new JSONObject();
JSONArray types = new JSONArray();
try {
location.put("lat", 123.4556);
location.put("lng", 123.4556);
params.put("location", location);
params.put("accuracy", 20);
params.put("name", "Event Name");
//only one type is available.
types.put("parking");
params.put("types", types);
params.put("language", "en");
} catch (Exception e) {}
// Show the request JSON data.
TextView reqTxtView = (TextView) findViewById(R.id.requestText);
try {
reqTxtView.setText(params.toString(2));
} catch (Exception e) {}
// POST to Google Server
myUtil.execute(params);
}
});
}
}
[PlacesHTTP.java]
package com.example.placeseventtest;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import org.json.JSONObject;
import android.os.AsyncTask;
import android.widget.TextView;
public class PlacesHTTP extends AsyncTask<JSONObject, Void, HttpResponse>{
private HttpPost post;
private HttpClient httpClient;
private String url;
private TextView txtView;
public PlacesHTTP(String api_key, TextView resultView) {
url = String.format("https://maps.googleapis.com/maps/api/place/add/json?sensor=false&key=%s", api_key);
txtView = resultView;
}
protected void onPreExecute() {
httpClient = new DefaultHttpClient();
post = new HttpPost(url);
post.setHeader("Accept", "application/json");
post.setHeader("Content-type", "application/json");
}
#Override
protected HttpResponse doInBackground(JSONObject... params) {
//Send data as JSON format
JSONObject opts = params[0];
StringEntity strEntity;
HttpResponse response = null;
try {
strEntity = new StringEntity(opts.toString());
post.setEntity(strEntity);
response = httpClient.execute(post);
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
protected void onPostExecute(HttpResponse result) {
if (result != null) {
// Display the result
try {
txtView.setText(EntityUtils.toString(result.getEntity()));
} catch (Exception e) {
e.printStackTrace();
}
} else {
txtView.setText("null");
}
}
}
I got this result:
