如何在java中使用HttpsUrlConnection

标签: java authentication curl https

我有一个命令行:

curl -u username:passwd -k "https://myserver/a/b/c"

当我在Ubuntu或Cygwin下调用它时,我会得到正确的信息。

现在我愿意用Java完成它。所以我有这样的Java代码:

    public class Test {

    public static String auth = "username:passwd";
    public static String url = "https:/myserver/a/b/c";

    public static void main(String[] args) {
        try {
            URL url = new URL(url);
            final byte[] authBytes = auth.getBytes(StandardCharsets.UTF_8);
            String encoding = java.util.Base64.getEncoder().encodeToString(authBytes);
            HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();

            connection.setRequestMethod("POST");

            connection.setRequestProperty("Authorization", encoding);

            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));

            String line;

            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

但它似乎不起作用并始终返回HTTP响应代码411。 java代码有问题吗?

先谢谢。

HTTP响应代码411表示“服务器拒绝接受没有定义内容长度的请求。”

HttpsUrlConnection应该可以为你做到这一点。查看setFixedLengthStreamingMode()。我想你还需要setDoOutput()
