SSIS Web服务-写入web服务

Question

我已经能够成功地在SSIS中使用web服务任务消费，但我不能弄清楚如何写入web服务，有人能帮助我吗？

谢谢

这个问题有点含糊，无法给出明确的答案，但是，猜测一下您的问题是，您已经能够从web服务(GET)读取数据，但现在您希望将数据写入(POST/PUT)到web服务。

如果是这样的话，最好的办法是使用脚本任务并使用C# (或VB)来调用所述web服务。我还建议对GET请求使用这种方式，而不是SSIS Web Service任务，后者不处理“较新”的web服务协议，如oAuth身份验证。

粗略样本如下：

      using System.Net
      using System.IO          

      string url 
            = "http://webservicehere.org";

        // create the request
        HttpWebRequest request 
            = (HttpWebRequest)HttpWebRequest.Create(url);

        // set the method to POST
        request.Method 
            = "POST";

        // set the content type, usually application/json or application/xml
        request.ContentType 
            = "application/json";

        // handle authentication, in this case the web service
        // requires the authentication token to be passed in as a
        // header called "Cookie"
        request.Headers.Add("Cookie", SqlAuthCookie);

        // get the stream object to use to write the request data
        StreamWriter requestWriter 
            = new StreamWriter(request.GetRequestStream());

        // write the data to the web service
        // where (data) is the JSON/XML that you are
        // sending to the endpoint
        requestWriter.Write(data);

        // close the connection upon completion
        requestWriter.Close();

        try
        {
            // read the response received from the web service
            HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();

            // code to handle the response goes here
            // i.e. deserialise json/xml to strongly typed objects

        }
        catch (WebException we)
        {
            // catch any exceptions thrown by the web service here
        }
        catch (Exception e)
        {
            // catch other exceptions here
        }
