Quick Start

Java code example 1

// Step 1 Basic encryption
String merchantNo = "Assign a merchant number";
String secretKey = "Assign keys";
String authorization = Base64.encode(merchantNo+":"+secretKey);

// 第二步 interface request
OkHttpClient client = new OkHttpClient().newBuilder().build();
MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, "{}");
Request request = new Request.Builder()
.url("https://domain/checkout/payment")
.method("POST", body)
.addHeader("Content-Type", "application/json")
.addHeader("Authorization", "Basic MTIzNDU2OjEyMzQ1Ng==")
.build();
Response response = client.newCall(request).execute();

Java code example 2

private static String merchantNo = "Assign a merchant number";
private static String secretKey = "Assign keys";
private static String domain = "Request a domain name";
private static String payUrl = "/checkout/payment";

public static void main(String[] args) {
    RestTemplate template = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    headers.setBasicAuth(merchantNo, secretKey);
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
    headers.setContentType(MediaType.APPLICATION_JSON);
    Map<String, Object> map = new HashMap<>();//Request JSON parameters
    HttpEntity<Map<String, Object>> request = new HttpEntity<>(map, headers);
    ResponseEntity<String> response = template.postForEntity(domain + payUrl, request, String.class);
    System.out.println(response.getBody());
}
