android使用navision web服務

Question

我需要使用android的NAV web服務。 我得到了具有「上」功能的「字母」代碼單元。

我在PC上設置了NAV Web服務（NTLM身份驗證）並關閉了防火牆（以便此服務在我的網絡中的其他設備上可見）。輸入登錄/密碼（我的PC帳戶）後，可以在瀏覽器（也可以在adroid設備上）訪問該服務。 如果我使用this code它與END_DOCUMENT空異常的「調用」崩潰... 是因爲身份驗證？

如果我使用此代碼連接

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

我得到401錯誤，而只是指定IP

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

返回代碼200（OK） 我怎樣才能發送憑證？我嘗試了幾種方法，但結果總是一樣的... 您是否有這個問題的經驗？

Answer 1

通過創建另一個Web Service的解決（寫在C＃，其中NAV服務器運行在同一臺PC上運行）讀取導航服務和Android通過該C與NAV WS通信＃WS

Answer 2

嗨你有沒有嘗試過用

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

Answer 3

這是http認證是如何supposed to work。你可以使用提琴手來看看你的中介正在做什麼。如果你想擺脫它，你將不得不做同樣的事情:)

那被稱爲與Navision認證是沒有野餐，因爲它使用SPNEGO或NTLM。如果您可以配置NTLM，則可以使用android-ntlm完成工作。類似於pungggi的回答除了httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());

Answer 4

我用soap_action做同樣及其工作般的魅力，看看下面的代碼可以幫助你：

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(); 
     }

1）添加下面瓶 JCIFS-1.3。 17.jar ksoap2-機器人組裝-3.0.0-罐與 - dependencies.jar

2）創建這些Java類 JCIFSEngine.java

      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） 調用此方法與paramater URL， 「用戶名」， 「口令」， 「則domainName」， 「的SystemName」

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

4）發送SOAP請求，其由肥皂的信封。

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