后XML“根元素丟失”

Question

發布XML數據時，我一直收到臭名昭著的“缺少根元素”錯誤。 有時它可以工作，但大多數情況下會引發錯誤。

C＃代碼：

 public string postXMLData(string destinationUrl, string requestXml)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
            byte[] bytes;
            bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
            request.ContentType = "text/xml; encoding='utf-8'";
            request.ContentLength = bytes.Length;
            request.Method = "POST";
            Stream requestStream = request.GetRequestStream();
            requestStream.Write(bytes, 0, bytes.Length);
            requestStream.Close();
            HttpWebResponse response;
            response = (HttpWebResponse)request.GetResponse();
            if (response.StatusCode == HttpStatusCode.OK)
            {
                Stream responseStream = response.GetResponseStream();
                string responseStr = new StreamReader(responseStream).ReadToEnd();
                return responseStr;
            }
            return "";
        }

XML數據：

<Person>
    <idPeople>0</idPeople>
    <AccountNumber>TEST02H</AccountNumber>
    <cFirstName>TEST 2</cFirstName>
    <cLastName>TEST 2</cLastName>
    <cTelWork/>
    <cTelMobile>0713473835</cTelMobile>
    <cEmail>myemail@mydomain.com</cEmail>
    <ubPPLIsActive>true</ubPPLIsActive>
    <ubPPLSMSOptIn>true</ubPPLSMSOptIn>
    <udPPLSMSOptInActivateDate>30/05/2017</udPPLSMSOptInActivateDate>
    <ulPPLAccessType>Administrator</ulPPLAccessType>
    <ubPPLNewsletterSignUp>true</ubPPLNewsletterSignUp>
    <ubPPLIncludeBuyerEmails>true</ubPPLIncludeBuyerEmails>
</Person>

Answer 1

對我來說，問題在2個地方。

1. 我要發布的應用程序出現錯誤，我已解決。 我通過將目標URL粘貼到瀏覽器中來查看發生了什么，從而發現了此錯誤。

2. 我需要System.Web.HttpUtility.UrlEncode XML。

最后我使用了這種方法。

WebClient client = new WebClient();
string xmlResult = client.DownloadString(_workContext.AccountingWebServiceLink + "?action=updatesecondary&xml=" + System.Web.HttpUtility.UrlEncode(strXML));
