navision web服务的android消费

Question

我需要使用来自 android 的 NAV Web 服务。 我得到了带有“上”功能的“字母”代码单元。

我已在我的 PC 上设置了 NAV Web 服务（NTLM 身份验证）并关闭了防火墙（以便该服务在我的网络中的其他设备上可见）。输入登录名/密码（我的 PC 帐户）后，可以在浏览器（也可以在 Android 设备上）访问该服务。 如果我使用this code，它会在“调用”时崩溃，并出现 END_DOCUMENT 空异常...... 是因为认证吗？

如果我使用此代码连接

HttpGet request = new
HttpGet("http://[myPC'sIP]:7047/DynamicsNAV/WS/SystemService");
HttpResponse response = client.execute(request);

我得到 401 错误，但只是指定 IP

HttpGet request = new HttpGet("http://[myPC'sIP]");
HttpResponse response = client.execute(request);

返回代码 200（正常） 如何发送凭据？我尝试了几种方法，但结果总是一样的...... 你有解决这个问题的经验吗？

1) 在罐子下面添加 jcifs-1.3.17.jar ksoap2-android-assembly-3.0.0-jar-with-dependencies.jar

2) 创建这些 java 类 JCIFSEngine.java

package com.demo.Authentication;
import jcifs.ntlmssp.NtlmFlags;
import jcifs.ntlmssp.Type1Message;
import jcifs.ntlmssp.Type2Message;
import jcifs.ntlmssp.Type3Message;
import jcifs.util.Base64;
import org.apache.http.impl.auth.NTLMEngine;
import org.apache.http.impl.auth.NTLMEngineException;

import java.io.IOException;

/**
 * Class taken from http://hc.apache.org/httpcomponents-client-ga/ntlm.html
 */
public final class JCIFSEngine implements NTLMEngine {

    private static final int TYPE_1_FLAGS =

            NtlmFlags.NTLMSSP_NEGOTIATE_NTLM2 |
            NtlmFlags.NTLMSSP_NEGOTIATE_ALWAYS_SIGN |
            NtlmFlags.NTLMSSP_REQUEST_TARGET;

    public String generateType1Msg(final String domain, final String workstation)
            throws NTLMEngineException {
        final Type1Message type1Message = new Type1Message(TYPE_1_FLAGS, domain, workstation);
        return Base64.encode(type1Message.toByteArray());
    }

    public String generateType3Msg(final String username, final String password,
            final String domain, final String workstation, final String challenge)
            throws NTLMEngineException {
        Type2Message type2Message;
        try {
            type2Message = new Type2Message(Base64.decode(challenge));
        } catch (final IOException exception) {
            throw new NTLMEngineException("Invalid NTLM type 2 message", exception);
        }
        final int type2Flags = type2Message.getFlags();
        final int type3Flags = type2Flags
                & (0xffffffff ^ (NtlmFlags.NTLMSSP_TARGET_TYPE_DOMAIN | NtlmFlags.NTLMSSP_TARGET_TYPE_SERVER));
        final Type3Message type3Message = new Type3Message(type2Message, password, domain,
                username, workstation, type3Flags);
        return Base64.encode(type3Message.toByteArray());
    }
}

    }
}

3) 使用参数 url,"username","password","domainName","SystemName" 调用此方法

 NtlmTransport ntlm = new NtlmTransport(url, "username", "password", "domainName","SystemName");

4) 发送包含肥皂信封的肥皂请求。

 ntlm.call("namespace/methodname", soapEnvelope);

Answer 2

我使用 soap_action 来做同样的事情，它的工作方式很迷人，看看下面的代码是否对你有帮助：

String namespace = "urn:microsoft-dynamics-schemas/codeunit/NavisionWS";
String url = "http://IP:7047/DynamicsNAV/WS/Codeunit/NavisionWS";   
String soap_action = "urn:microsoft-dynamics-schemas/codeunit/NavisionWS:GetLoginInfo";
String method_name = "GetLoginInfo";
try
        {
              SoapObject request = new SoapObject(namespace, method_name);    
              SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

               envelope.dotNet = true;   
               envelope.setOutputSoapObject(request);   
               HttpTransportSE transport = new HttpTransportSE(url);    
               transport.call(soap_action, envelope); // Receive Error here!
                    SoapObject result = (SoapObject) envelope.getResponse();
                    great = result.toString();
        }
        catch (Exception e)
        {
            e.printStackTrace();
                 great = e.toString();
                 Toast.makeText(this, great, Toast.LENGTH_LONG).show();
        }

Answer 3

这就是supposed to work 的http 身份验证方式。您可以使用 fiddler 来查看您的中介在做什么。如果你想摆脱它，你必须做同样的事情:)

也就是说，使用 Navision 进行身份验证并不简单，因为它使用 SPNEGO 或 NTLM。如果您可以配置 NTLM，您也许可以使用android-ntlm 来完成工作。除了httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());

之外，看起来类似于 pungggi 的答案

Answer 4

您好，您是否尝试过使用

var httpClient = new DefaultHttpClient();
NTCredentials nt = new NTCredentials("user", "pass", "", "domain");
httpClient.GetCredentialsProvider().SetCredentials(AuthScope.ANY, nt);

Answer 5

通过创建另一个读取 NAV 服务的 Web 服务（用 C# 编写，在运行 NAV 服务器的同一台 PC 上运行）解决，android 通过此 C# WS 与 NAV WS 通信
