接口访问 URL直接输入浏览器地址返回正常数据，但httpCode一直是404

Question

接口API：https://openapi.zhe800.com/doc/zhe800.order/zhe800.order.detail.get/index.html

浏览器地址栏直接输入URl

 URL url = https://openapi.zhe800.com/api/erp/v2/orders/6181937746877.json;
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();

if ((conn instanceof HttpsURLConnection)) {
            HttpsURLConnection connHttps = (HttpsURLConnection) conn;
            if (ignoreSSLCheck) {
                try {
                    SSLContext ctx = SSLContext.getInstance("TLS");
                    ctx.init(null,
                            new TrustManager[] { new TrustAllTrustManager() },
                            new SecureRandom());
                    connHttps.setSSLSocketFactory(ctx.getSocketFactory());

                    connHttps.setHostnameVerifier(new HostnameVerifier() {
                        public boolean verify(String hostname,SSLSession session) {
                            return true;
                        }
                    });
                } catch (Exception e) {
                    throw new IOException(e);
                }

                    conn = connHttps;

        conn.setRequestMethod("get");
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setRequestProperty("Host", url.getHost());
        conn.setRequestProperty("User-Agent", "Top4Net");
        conn.setRequestProperty("Content-Type", "multipart/related;charset=utf-8");
        conn.setConnectTimeout(30000);
        return conn;

        int         code =  conn.getResponseCode();

code 始终为404.。。

如果网页存在的话，必然是人为做了访问限制，如果不存在，按常理就返回404
