我是android的新手。所以我可以告诉我如何发出http get请求，例如

GET /photos?size=original&file=vacation.jpg HTTP/1.1
Host: photos.example.net:80
Authorization: OAuth realm="http://photos.example.net/photos",
    oauth_consumer_key="dpf43f3p2l4k3l03",
    oauth_token="nnch734d00sl2jdk",
    oauth_nonce="kllo9940pd9333jh",
    oauth_timestamp="1191242096",
    oauth_signature_method="HMAC-SHA1",
    oauth_version="1.0",
    oauth_signature="tR3%2BTy81lMeYAr%2FFid0kMTYa%2FWM%3D"

在安卓（java）中？

你会想要熟悉 Android 中的 InputStreams 和 OutputStreams，如果你之前在常规 java 中做过这件事，那么它本质上是一样的。您需要打开请求属性为“GET”的连接，然后将参数写入输出流并通过输入流读取响应。您可以在下面的代码中看到这一点：

        try {
        URL url = null;
        String response = null;
        String parameters = "param1=value1&param2=value2";
        url = new URL("http://www.somedomain.com/sendGetData.php");
        //create the connection
        connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded");
        //set the request method to GET
        connection.setRequestMethod("GET");
        //get the output stream from the connection you created
        request = new OutputStreamWriter(connection.getOutputStream());
        //write your data to the ouputstream
        request.write(parameters);
        request.flush();
        request.close();
        String line = "";
        //create your inputsream
        InputStreamReader isr = new InputStreamReader(
                connection.getInputStream());
        //read in the data from input stream, this can be done a variety of ways
        BufferedReader reader = new BufferedReader(isr);
        StringBuilder sb = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        //get the string version of the response data
        response = sb.toString();
        //do what you want with the data now

        //always remember to close your input and output streams 
        isr.close();
        reader.close();
    } catch (IOException e) {
        Log.e("HTTP GET:", e.toString());
    }
