解释：我正在开发一个java应用程序，它通过cpas api（类似于tweepy）发送文本消息。我正在使用curl请求发送消息。来自java的请求似乎已发送，但我收到了401代码。我假设请求的身份验证编码存在问题。代码如下：

URL url = new URL("https://api.zang.io/v2/Accounts/ACe1889084d37de951ef064200aecbe4b2/SMS/Messages");

字符串auth=auth+“：”+令牌；

String encodeedAuth = Base64.getEncoder().withoutPadding().encodeToString(auth.getBytes());
    HttpURLConnection http = (HttpURLConnection)url.openConnection();
    http.setRequestMethod("POST");
    http.setDoOutput(true);
    http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    http.setRequestProperty("Authorization", "Basic " + encodeedAuth);

    String data = "From=+14132698029&To=17817381451&Body=New Test";

    byte[] out = data.getBytes(StandardCharsets.UTF_8);

    OutputStream stream = http.getOutputStream();
    stream.write(out);

    System.out.println(http.getResponseCode() + " " + http.getResponseMessage());
    http.disconnect();
