JAVA代码如下：

params.add(new BasicNameValuePair(“postcode”, “3000”));
params.add(new BasicNameValuePair(“country”, “Australia”));
String query = URLEncodedUtils.format(params, “UTF-8”);
String urlPrefix = “api.auspost.com.au”;

httpGet.addHeader(“Cookie”, “OBBasicAuth=fromDialog”);
httpGet.addHeader(BasicScheme.authenticate(
    new UsernamePasswordCredentials(apiKeyUserName, apiKeyPassword),
    “US-ASCII”,false));

HttpResponse response = httpclient.execute(httpGet);
if(response.getStatusLine().getStatusCode() != 200)
{
  throw new Exception(“Error: “”” + response.getStatusLine().getReasonPhrase() + “”” – Code: ” + response.getStatusLine().getStatusCode());
}
try

  System.out.println(new String(responseBody));
}
