【问题描述】：
我在 Dynamics CRM online 2015 中创建了一个插件，用于在 SharePoint Online 文档库中创建文件夹。该插件工作正常。但是，当 CRM 中的帐户名称发生更改时，我想重命名文档库中的文件夹。
由于CRM和SharePoint都在线，所以我不能使用Microsoft.SharePoint.Client.dll所以我根据以下文章使用了SPOAuthUtility Class
https://www.develop1.net/public/post/SharePoint-Integration-Reloaded-e28093-Part-3.aspx
创建文件夹的代码工作正常，我使用以下代码在 CRM 中更改帐户名称时重命名文件夹：
string restFolderQuery = "_api/web/getfolderbyserverrelativeurl('" +
rootFolderName + "/" + oldName + "')/ListItemAllFields";
Uri url = new Uri(String.Format("{0}/{1}", webSiteUrl, restFolderQuery));
byte[] result = HTTPHelper.SendODataJsonRequest(
url,
"POST", // setting data to SP through the rest api usually uses the POST verb
Encoding.UTF8.GetBytes("{ '__metadata':{ 'type': 'SP.Data.AccountItem' },
'FileLeafRef': '" + newName + "' ,'Title:': '" + newName + "' }"),
(HttpWebRequest)HttpWebRequest.Create(url),
SpoAuthUtility.Current, // pass in the helper object that allows us to make authenticated calls to SPO rest services
new Dictionary<string, string>() {
{"IF-MATCH", "*"}, {"X-HTTP-Method", "MERGE" }
}
);
这将调用 HTTPHelper 类中的 SendODataJsonRequest 函数：
public static byte[] SendODataJsonRequest(Uri uri, String method, byte[] requestContent, HttpWebRequest clientHandler, SpoAuthUtility authUtility, Dictionary<string, string> headers = null)
{
if (clientHandler.CookieContainer == null)
clientHandler.CookieContainer = new CookieContainer();
CookieContainer cookieContainer = authUtility.GetCookieContainer(); // get the auth cookies from SPO after authenticating with Microsoft Online Services STS
foreach (Cookie c in cookieContainer.GetCookies(uri))
{
clientHandler.CookieContainer.Add(uri, c); // apppend SPO auth cookies to the request
}
// string digest = SpoAuthUtility.GetRequestDigest();
Dictionary<string, string> _dic = new Dictionary<string, string>();
_dic.Add("Authorization", "Bearer" + cookieContainer.GetCookieHeader(uri));
return SendHttpRequest(
uri,
method,//digest,
requestContent,
"application/json;odata=verbose;charset=utf-8", // the http content type for the JSON flavor of SP REST services
clientHandler,
_dic);
}
依次调用 SendHttpRequest 函数：
public static byte[] SendHttpRequest(Uri uri, String method, byte[] requestContent = null, string contentType = null, HttpWebRequest clientHandler = null, Dictionary<string, string> headers = null)
{
try
{
HttpWebRequest request = clientHandler == null ? (HttpWebRequest)HttpWebRequest.Create(uri) : clientHandler;
byte[] responseStream;
request.Method = method;
request.Accept = contentType;
request.UserAgent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)"; // This must be here as you will receive 403 otherwise
request.AllowAutoRedirect = false; // This is key, otherwise it will redirect to failed login SP page
// append additional headers to the request
if (headers != null)
{
foreach (var header in headers)
{
if (request.Headers.AllKeys.Contains(header.Key))
{
request.Headers.Remove(header.Key);
}
request.Headers.Add(header.Key, header.Value);
}
}
if (requestContent != null && (method == "POST" || method == "PUT" || method == "DELETE"))
{
if (!string.IsNullOrEmpty(contentType))
{
request.ContentType = contentType; // if the request has a body set the MIME type
}
request.ContentLength = requestContent.Length;
using (Stream s = request.GetRequestStream())
{
s.Write(requestContent, 0, requestContent.Length);
s.Close();
}
}
// Not using Using here as you may still like to access the reponse outside of this method
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8"));
responseStream = Encoding.UTF8.GetBytes(sr.ReadToEnd());
return responseStream;
}
catch (Exception ex)
{
throw;
}
}
使用提供的凭据，相同的代码在控制台应用程序中运行良好，并且确实重命名了指定的文件夹，但在 CRM 插件中不起作用
此代码创建的 HTTPRequest 似乎有问题，因为我从服务器收到错误响应： 远程服务器返回错误（400）错误请求
谁能帮我用代码从动态 CRM 插件重命名 SharePoint 文件夹
【问题讨论】：
-
Microsoft.SharePoint.Client.dll 有依赖关系吗？
