使用C＃进行批量API集成

Question

我正在尝试创建一个批量API来将数据发送到Salesforce。这是我的代码

        string userName = "XXXX";
        //Console.Write("Enter password: ");
        string password = "XXX";
        string SessionId = SalesforceLogin(userName, password);
        string JobId = CreateJob(SessionId, "insert", "Contact");
        byte[] inputFileData = null;
        string jobId = string.Empty;
        string resultId = string.Empty;
        string batchId = string.Empty;
        if (JobId.Length > 0)
        {
            System.IO.FileInfo oFile = null;
            //oFile = New System.IO.FileInfo("data.csv")
            oFile = new System.IO.FileInfo(@"D:\request.txt");

            System.IO.FileStream oFileStream = oFile.OpenRead();
            long lBytes = oFileStream.Length;
            int a = (int)lBytes; //modified after conversion
            if ((lBytes > 0))
            {
                byte[] fileData = new byte[lBytes];
                // Read the file into a byte array
                oFileStream.Read(fileData, 0, a);   //modified after conversion
                oFileStream.Close();

                //Get the file where the Query is present
                inputFileData = fileData;
            }

             batchId= AddBatch(SessionId, JobId, inputFileData);

之后，我创建了一个工作

private static string CreateJob(string sessionId, string sfOperation, string sfObjectName)
        {
            string str = "";
            string reqURL = "";

            byte[] bytes;

            XmlDocument reqDoc;
            XmlDocument respDoc;

            str = ""
                + "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n" // added \r\n as recommended by L.B's answer
                + "<jobInfo xmlns=\"http://www.force.com/2009/06/asyncapi/dataload\">"
                + "    <operation></operation>" // removed "+sfOperation+"
                + "    <object></object>" // removed "+sfObjectName+"
                + "    <contentType>XML</contentType>" // should be CSV, NOT XML
                + "</jobInfo>"
            ;

            reqURL = "https://ap2.salesforce.com/services/async/23.0/job";
            reqDoc = new XmlDocument();
            reqDoc.LoadXml(str);

            // added XML modifications
            reqDoc.GetElementsByTagName("operation")[0].InnerText = sfOperation;
            reqDoc.GetElementsByTagName("object")[0].InnerText = sfObjectName;

            bytes = System.Text.Encoding.ASCII.GetBytes(reqDoc.InnerXml);
            respDoc = Post(bytes, reqURL, sessionId); // create job

            string JobId = (respDoc != null) ?
                (respDoc.GetElementsByTagName("id").Count > 0) ?
                    (respDoc.GetElementsByTagName("id")[0].InnerText) :
                    "" :
                ""
            ;

            return JobId;
        }`

然后我创建一个批处理

 private static string AddBatch(string sessionId, string jobId, byte[] fileBytes)
        {
            string reqURL = "https://ap2.salesforce.com/services/async/23.0/job/" + jobId + "/batch";
            XmlDocument respDoc = Post(fileBytes, reqURL, sessionId);
            string batchId = (respDoc != null) ?
                (respDoc.GetElementsByTagName("id").Count > 0) ?
                    (respDoc.GetElementsByTagName("id")[0].InnerText) :
                    "" :
                ""
            ;
            return batchId;
        }

然后是Post方法

private static XmlDocument Post(byte[] bytes, string reqURL, object sfSessionId)
        {
            WebRequest req = WebRequest.Create(reqURL);
            req.Method = "POST";
            if ((bytes != null))
            {
                req.ContentLength = bytes.Length;
            }
            req.ContentType = "application/xml; charset=UTF-8"; // should be text/csv; when passing a CSV file
            req.Headers.Add("X-SFDC-Session: " + sfSessionId);

            System.IO.Stream strm = req.GetRequestStream();
            if ((bytes != null))
                strm.Write(bytes, 0, bytes.Length);
            strm.Close();

             HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
            System.IO.Stream respStrm = resp.GetResponseStream();

            XmlDocument respDoc = new XmlDocument();
            respDoc.Load(respStrm);

            return respDoc;
        }

一切顺利但是当我尝试保存Lead on Data时，它会显示错误

InvalidBatch：无法解析XML。无法获得下一个元素

创建批次后我得到结果

<?xml version="1.0" encoding="UTF-8"?><batchInfo xmlns="http://www.force.com/2009/06/asyncapi/dataload"><id>7512800000C8OHAAA3</id><jobId>75028000008qk53AAA</jobId><state>Queued</state><createdDate>2017-05-30T14:11:45.000Z</createdDate><systemModstamp>2017-05-30T14:11:45.000Z</systemModstamp><numberRecordsProcessed>0</numberRecordsProcessed><numberRecordsFailed>0</numberRecordsFailed><totalProcessingTime>0</totalProcessingTime><apiActiveProcessingTime>0</apiActiveProcessingTime><apexProcessingTime>0</apexProcessingTime></batchInfo>

再插入批处理后，这个作业将如何执行。我正在粘贴所有代码，因为如果我得到答案，它可能对某人有帮助:)。
