我的客户

conn.setRequestProperty("Content-Type", "application/json");
String input = "{\"customerCode\":\"customerCode\",\"productCode\":\"productCode\",\"requiredQty\":10}";
OutputStream os = conn.getOutputStream();
os.write(input.getBytes());
os.flush();
if (conn.getResponseCode() != HttpURLConnection.HTTP_CREATED) {

conn.disconnect();
} catch (MalformedURLException e) {

{
"customerCode":"customerCode",
"productCode":"productCode",
"requiredQty":10
}
