HTTP GET with Non-USASCII Query Params

See more HTTP Examples

This example illustrates how query parameters in a URL are typically encoded and transmitted. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean success = false;

    // This example assumes the Chilkat HTTP API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // First, let's load the string "Grünhöfer GmbH" from a file.  (This is a fictitious company name.)
    // The file uses the utf-8 charset encoding.
    CkStringBuilder sbCompanyName = new CkStringBuilder();
    success = sbCompanyName.LoadFile("qa_data/txt/companyName.txt","utf-8");
    // Assuming success for this example...

    // We'll send an HTTP GET request to https://chilkatsoft.com/example?company_name={company name}

    // When sending an HTTP GET request with query parameters that contain accented characters 
    // (e.g., umlauts: ä, ö, ü), they must be percent-encoded (URL encoded) to ensure proper transmission and 
    // interpretation by the server.  This is based on their UTF-8 byte values.
    CkStringBuilder sbUrl = new CkStringBuilder();
    sbUrl.Append("https://chilkatsoft.com/example?company_name=");
    sbUrl.Append(sbCompanyName.getEncoded("url","utf-8"));

    CkHttp http = new CkHttp();

    // Send the following HTTP GET request:

    // GET /example?company_name=Gr%C3%BCnh%C3%B6fer%20GmbH HTTP/1.1
    // Host: chilkatsoft.com
    // Accept: */*
    // Accept-Encoding: gzip

    CkStringBuilder sbResponse = new CkStringBuilder();
    success = http.QuickGetSb(sbUrl.getAsString(),sbResponse);
    if (success == false) {
        Log.i(TAG, http.lastErrorText());
        return;
