Sending a request to the server using POST

[Angus Ferguson]

Hi

I am trying to send a request to the Google server, using this code:

void sendRequest(String code) throws Exception {
		// System.out.println("Start sending " + action + " request");

		String serviceURL = "https://accounts.google.com/o/oauth2/token?"
				+ code
				+ "&client_id=673035080615.apps.googleusercontent.com&client_secret=xxxx&redirect_uri=https://statstest.web.com/code&grant_type=authorization_code";
		URL url = new URL(
				"https://accounts.google.com/o/oauth2/token?"
						+ code
						+ "&client_id=673035080615.apps.googleusercontent.com&client_secret=xxxx&redirect_uri=https://statstest.web.com/code&grant_type=authorization_code");

		PostMethod postmethod = new PostMethod(serviceURL);
		HttpURLConnection rc = (HttpURLConnection) url.openConnection();
		System.out.println("Connection opened " + rc);
		rc.setRequestMethod("POST");
		rc.setDoOutput(true);
		rc.setDoInput(true);
		rc.setRequestProperty("Content-Type", "text/xml; charset=utf-8");

		rc.connect();
		OutputStreamWriter out = new OutputStreamWriter(rc.getOutputStream());

		out.flush();
		System.out.println("Request sent, reading response ");
		InputStreamReader read = new InputStreamReader(rc.getInputStream());

		System.out
				.println(read.toString()
						+ "    read.toString();    read.toString();    read.toString();");

		// note that Content-Length is available at this point
		StringBuilder sb = new StringBuilder();
		int ch = read.read();
		while (ch != -1) {
			sb.append((char) ch);
			ch = read.read();
		}
		// response = sb.toString();
		read.close();
		rc.disconnect();
	}

I have read 300 times the query and I think all is correct

I get the error:

java.io.IOException: Server returned HTTP response code: 400 for URL: https://accounts.google.com/o/oauth2/token?code

Any idea please?

Many Thanks

You are encoding the parameters in the URL - that is for GET operations. Why do you think you need the POST method?

(400 = request syntactically incorrect)

Hi Bill,

I am using a POST method because GA launches the "405 invalid method error" if you don´t use it.

Then what way must I encode the URL as String?

Many Thanks,

For POST the parameters are sent as the body of the request and not as part of the URL.

Plus, its better to use a well documented and well tested library, such as the Apache HTTP client software than to write your own. You will get the mainline code to work, but there are lots of edge cases that someone else has solved before you even start.

It works now.

Many Thanks
