linux如何使用java卷曲URL并将输出保存到文件

Question

我是java新手，需要帮助了解如何在java中使用cURL，以及如何在运行时将cURL命令的输出保存到文件中

让我考虑一下下面的URL，我必须在Linux机器中使用{{CD1>}。

http://maniv.com/maniv/rest?method=sendMessage&msg_type=binary&parameter1=9999999&parameter2=9999999

当我在linux中使用curl "http://maniv.com/maniv/rest?method=sendMessage&msg_type=binary&parameter1=9999999&parameter2=9999999"点击上面的URL时，它将给出如下输出：

Message | sent | successfully

现在，每次更改parameter1并点击URL时，我都需要基于parameter1作为文件名将输出写入一个新文件

谢谢你的努力。我试了很久才得到答案！ `

    String url = "http://maniv.com/maniv/rest";
    String charset = "UTF-8";
    String method = "sendMessage";
    String msg_type = "binary";
    String parameter1 = "9999999";
    String parameter2 = "0000000";
    String msg = "001100110001100011";

    // ...
    StringBuffer sb = null;
    String query = String
            .format("method=%s&msg_type=%s&userid=%s&password=%s&msg=%s",
                    URLEncoder.encode(method, charset),
                    URLEncoder.encode(msg_type, charset),
                    URLEncoder.encode(userid, charset),
                    URLEncoder.encode(password, charset),
                    URLEncoder.encode(msg, charset));
    try {
        URL requestUrl = new URL(url + "?" + query);
        HttpURLConnection conn = (HttpURLConnection) requestUrl.openConnection();
        conn.setDoOutput(true);
        conn.setRequestMethod("GET");
        OutputStreamWriter osw = new OutputStreamWriter(conn.getOutputStream());
        osw.write(query);
        osw.flush();
        BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String in = "";
        sb = new StringBuffer();
        while ((in = br.readLine()) != null) {
            sb.append(in + "\n");
            System.out.println("Output:\n" +in);
        }
    } catch (Exception e) {
        System.out.println("Exception occured" + e);
    }
}

}`

您必须在Java中使用curl命令吗？您可以使用HttpClient获取html文件吗http://hc.apache.org/httpclient-3.x/

请参阅这个问题：Read url to string in few lines of java code。它提供了很好的答案
