如何从URL中获取字符串而不省略JAVA中的空格

Question

I have a simple program that sends a GET request and fetches a string. The URL is a PHP page I wrote that fetches some data from a database on the server and parses it into a string with a bunch of white-space characters (which I need). The problem is the spaces get omitted in the response to the java app, and my question is how to avoid omitting them?

My java code:

URL servicesUrlObj = new URL("https://myurl.mysite.com/placeholder.php");
HttpURLConnection connection = (HttpURLConnection) servicesUrlObj.openConnection();

connection.setRequestMethod("GET");

int responseCode = connection.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + servicesUrlObj);
System.out.println("Response Code : " + responseCode);

BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer content = new StringBuffer();

while ((inputLine = reader.readLine()) != null) {
    content.append(inputLine);
}
reader.close();

System.out.println(content.toString());

original string:

200329951 123 3 03/09/18

the string that gets returned from the request:

200329951123303/09/18

Answer 1

这不是一个非常优雅的解决方案，但是您可以考虑将content.append(" ")到while循环中，甚至只是将当前行变成content.append(inputLine + " ");

Thanks to Manu Rivas's comment, i found the problem. I wasn't appending the spaces to the output parameter in my php file correctly. I did:

$spaces . ' ';

instead of:

$spaces = $spaces . ' ';
