我被要求移植一个我正在写入Java的PHP模块。我以前使用PHP的本地cURL库,现在试图用HttpURLConnection实现相同的操作。带有HttpURLConnection的Java cURL替代方案
这是我想和卷曲做呼叫:
curl -u 'ExactID:Password' \
-H 'Content-Type: application/json; charset=UTF-8' \
-H 'Accept: application/json' \
-d '{
"transaction_type":"00",
"amount":"15.75",
"cardholder_name":"PaulTest",
"transarmor_token":"3000",
"credit_card_type":"Visa",
"cc_expiry":"0016",
}' \
https://api.demo.globalgatewaye4.firstdata.com/transaction/v11
下面是我在Java中,它返回一个HTTP 400错误。有任何想法吗?
public static void main(String[] args) {
URL url = new URL("https://api.demo.globalgatewaye4.firstdata.com/transaction/v11");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
conn.setRequestProperty("Accept", "application/json");
String userpass = "ExactID" + ":" + "Password";
String basicAuth = "Basic " + new String(new Base64().encode(userpass.getBytes()));
conn.setRequestProperty ("Authorization", basicAuth);
JSONObject obj = new JSONObject();
obj.put("transaction_type", "00");
obj.put("amount", "10");
obj.put("cardholder_name", "PaulTest");
obj.put("transarmor_token", "3000");
obj.put("cc_expiry", "0016");
obj.put("credit_card_type", "Visa");
String input = obj.toString();
System.out.println(input);
OutputStream os = conn.getOutputStream();
os.write(input.getBytes());
os.flush();
if (conn.getResponseCode() != HttpURLConnection.HTTP_CREATED) {
throw new RuntimeException("Failed : HTTP error code : "+ conn.getResponseCode() + conn.getResponseMessage());
}
看起来不错,试试看看更多的信息conn.getErrorStream() –
