我已经成功地能够在 SSIS 中使用 web 服务任务，但我无法弄清楚如何写入 web 服务，有人可以帮我解决这个问题。

谢谢

这个问题有点含糊，无法给出明确的答案，但是，猜测您的问题是您已经能够从 Web 服务 (GET) 读取数据，但您现在想要编写 ( POST/PUT) 数据到 Web 服务。

如果是这样，您最好的选择是使用脚本任务并使用 C#（或 VB）来调用所述 Web 服务。对于 GET 请求，我也建议使用此方法，而不是 SSIS Web 服务任务，它不处理“较新”的 Web 服务协议，例如 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
        }
