如何從Oracle調用ASP.NET webservice？

Question

我們如何從oracle調用一個asp.net webservice，我們可以有一個存儲過程來調用一個asp.net webservice嗎？

Answer 1

這是一個簡單的存儲過程，它從oracle 調用一個簡單的ASP.NET附加Web服務，它使我們得到了由Oracle提供的兩個數字的附加結果。

CREATE OR REPLACE PROCEDURE sp_WsAdd 
(

    P_NUM1 number, 
    P_NUM2 number 
) 
AS 
V_INVELOP_TEMP VARCHAR2(32767); 
V_INVELOP  VARCHAR2(32767); 
V_REQUEST  UTL_HTTP.REQ; 
V_RESPONSE UTL_HTTP.RESP; 
V_WSDL_URL VARCHAR2(2000):='Address of your Webservice'; 
V_XML XMLTYPE; 
BEGIN 
    V_INVELOP:='<?xml version="1.0" encoding="utf-8"?> 
    <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> 
<soap:Body> 
    <add xmlns="http://tempuri.org/"> 
    <num1>'||P_NUM1||'</num1> 
    <num2>'||P_NUM2||'</num2> 
    </add> 
</soap:Body> 
</soap:Envelope>'; 

    V_REQUEST:= UTL_HTTP.BEGIN_REQUEST(V_WSDL_URL, 'POST','HTTP/1.1'); 
       UTL_HTTP.SET_BODY_CHARSET(V_REQUEST, 'UTF-8'); 

    UTL_HTTP.SET_HEADER(V_REQUEST, 'Content-Type', 'text/xml'); 
    UTL_HTTP.SET_HEADER(V_REQUEST, 'Content-Length', LENGTH(V_INVELOP)); 
    UTL_HTTP.SET_HEADER(V_REQUEST, 'SOAPAction', 'http://tempuri.org/add'); 
    UTL_HTTP.WRITE_TEXT(V_REQUEST, V_INVELOP); 
    V_RESPONSE := UTL_HTTP.GET_RESPONSE(V_REQUEST); 
      dbms_output.put_line('Response Received'); 
      dbms_output.put_line('--------------------------');                                                     
      dbms_output.put_line ('Status code: ' || V_RESPONSE.status_code); 
      dbms_output.put_line ('Reason phrase: ' || V_RESPONSE.reason_phrase); 

    UTL_HTTP.READ_TEXT(V_RESPONSE, V_INVELOP); 
    UTL_HTTP.END_RESPONSE(V_RESPONSE); 

       V_INVELOP := REPLACE(V_INVELOP,'xmlns="http://tempuri.org/"',''); 
       V_XML:= XMLTYPE(V_INVELOP); 
       dbms_output.put_line('Value='||V_XML.extract('//addResult/text()').getStringVal()); 

    commit; 

    END; 
    /

此存儲過程的Web服務是

[WebMethod] 
    public string add(int num1, int num2) 
    { 
    return (num1 + num2).ToString(); 
    }
