Salesforce Bulk API 基于.Net平台下的实施

在最近的salesforce实施项目中应用到Bulk API来做数据接口。顺便把实际应用的例子写下来。希望对做salesforce接口的朋友有借鉴作用。

一 参考网络牛人写好的Demo.

下载地址：https://github.com/lfreeland/Salesforce-Bulk-API-Starter

注意事项：

1)  目前的salesforce 禁用了TLS1.0,所以这个代码要加上

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

2)  引入enterprise.wsdl 时候，目前是发现有个bug.

不清楚怎么引用webservice的朋友，可以先借鉴一下这个好博客

需要修改reference.cs里面的两个地方，把[][]二维数组改为[] , 方能避免编译错误。

3）关键步骤

a). Connected and get sessionId

         private void Login()
         {
             System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
             _sfService = new SFDC.SforceService();
             _sfService.Url = _LoginURL;
             _loginResult = _sfService.login(_UserName, _Password);
             _sfService.Url = _loginResult.serverUrl;
             SessionID = _loginResult.sessionId;
             _urlheader = "https://" + _sfService.Pod + ".salesforce.com";
             //SforceService sfService = new SforceService();
             _sfService.SessionHeaderValue = new SessionHeader();
             _sfService.SessionHeaderValue.sessionId = _loginResult.sessionId;

         }

b). Create Job

         public Job CreateJob(CreateJobRequest createJobRequest)
         {
             String jobRequestXML =
             @"<?xml version=""1.0"" encoding=""UTF-8""?>
              <jobInfo xmlns=""http://www.force.com/2009/06/asyncapi/dataload"">
                <operation>{0}</operation>
                <object>{1}</object>
                {3}
                <contentType>{2}</contentType>
              </jobInfo>";

             String externalField = String.Empty;

             if (String.IsNullOrWhiteSpace(createJobRequest.ExternalIdFieldName) == false)
             {
                 externalField = "<externalIdFieldName>" + createJobRequest.ExternalIdFieldName + "</externalIdFieldName>";
             }

             jobRequestXML = String.Format(jobRequestXML,
                                           createJobRequest.OperationString,
                                           createJobRequest.Object,
                                           createJobRequest.ContentTypeString,
                                           externalField);

             String createJobUrl = "https://" + _sfService.Pod + ".salesforce.com/services/async/31.0/job";

             String resultXML = invokeRestAPI(createJobUrl, jobRequestXML);

             return Job.Create(resultXML);
         }

c). Create BatchRequest

         public Batch CreateBatchRequest(string JobID, string filepath)
         {
             HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(_urlheader + "/services/async/31.0/job/" + JobID + "/batch");
             request.Method = WebRequestMethods.Http.Post;
             request.ContentType = "text/csv; charset=GB2312";
             request.Headers.Add("X-SFDC-Session", SessionID);
             request.KeepAlive = false;
             request.UserAgent = ".NET Framework Test Client";
             //"C:\SalesforceStudy\Project_Code\MyAccountImportData.csv"
             byte[] byteArray = File.ReadAllBytes(filepath);
             request.ContentLength = byteArray.Length;
             using (var writeStream = request.GetRequestStream())
             {
                 writeStream.Write(byteArray, , byteArray.Length);
             }
             using (var response = (HttpWebResponse)request.GetResponse())
             {
                 using (var responseStream = response.GetResponseStream())
                 {
                     if (responseStream != null)
                         using (var reader = new StreamReader(responseStream))
                         {
                             string responseValue = reader.ReadToEnd();
                             return Batch.CreateBatch(responseValue);
                         }
                 }
             }
             return null;
         }
