java - 使用 Java 时 XML-RPC 中的 addAttachment 错误

Question

我的Java代码

import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Vector;
import helma.xmlrpc.*;

public class test {

    private final static String server_url =
        "http://confluence.xyz.com:8080/rpc/xmlrpc";

    public static void main (String [] args) {
        try {

            XmlRpcClient server = new XmlRpcClient(server_url);

            Vector<Object> params = new Vector<Object>(2);
            params.add("user");
            params.add("pass");   

            String token = (String) server.execute("confluence2.login", params );
            System.out.println(token);

            Vector<Object> page = new Vector<Object>(3);
            page.add(token);
            page.add("~username");
            page.add("test_page");

            Object token1 = server.execute("confluence2.getPage", page );
            System.out.println(token1.hashCode());


            String fileName  = "C:/New folder/a.jpeg";
            String contentType = "image/jpeg";

            Vector<Object> attachment = new Vector<Object>(2);
            attachment.add("a.jpeg");
            attachment.add(contentType);
            System.out.println(attachment);

            byte[] bytes = Files.readAllBytes(Paths.get(fileName));
            System.out.println(bytes);

            Vector<Object> attach = new Vector<Object>(4);
            attach.add(token);
            attach.add(token1.hashCode());
            attach.add(attachment);
            attach.add(bytes);
            System.out.println(attach);
            server.execute("confluence2.addAttachment", attach);

        }
         catch (Exception exception) {
            System.err.println("JavaClient: " + exception.toString());
        }
    }
}

除了调用“addAttachment”的行之外，一切正常，

我得到的错误是

JavaClient: helma.xmlrpc.XmlRpcException: java.lang.NoSuchMethodException: com.sun.proxy.$Proxy2104.addAttachment(java.lang.String, int, java.util.Vector, [B)

任何人都可以帮助我使用我应该使用的任何其他库。看来 helma.xmlrpc 没有 addAttachment 方法

Answer 1

我使用了 org.apache.xmlrpc.client.XmlRpcClient 而不是 helma，但概念应该是相同的。这并不是说“helma.xmlrpc 没有 addAttachment 方法”，而是您使用错误的参数调用 addAttachment() 。尝试使用 https://developer.atlassian.com/confdev/confluence-rest-api/confluence-xml-rpc-and-soap-apis/remote-confluence-methods 中列出的正确参数来调用它

addAttachment(String token, long contentId, Attachment attachment, byte[] attachmentData)

所以对于 apache xmlrpc，我的部分代码如下所示:

    //add attachment to the page
    byte[] bytes = FileUtils.readFileToByteArray(new File(FILE_TO_ATTACH));
    Map<String, String> attachInfo = new HashMap<String, String>();
    attachInfo.put("fileName", FILENAME);       
    attachInfo.put("contentType", CONTENT_TYPE);
    attachInfo.put("comment", COMMENT);

    //actually add it now
    client.execute("confluence1.addAttachment", new Object[]{token, PAGEID, attachInfo, bytes});
