寫在前面
最近對文檔庫的知識點進行了整理，也就有了這篇文章，當時查找這些接口，並用在實踐中，確實廢了一些功夫，也為了讓更多的人走更少的彎路。

WebHttpRequest在sharepoint文檔庫中的使用
[sharepoint]修改Item或者File的Author和Editor
文件上傳
通過rest api上傳到sharepoint文檔庫。
上傳文件api
string strApi = "GetFolderByServerRelativeUrl('" + strFileServerRelativeUrl + "')/Files/Add(url='" + strFileName + "',overwrite=true)?$select=Name,ServerRelativeUrl,TimeCreated,TimeLastModified,Exists,Length";
strFileServerRelativeUrl：文件在sharepoint文檔庫中的相對路徑，比如：/server/libdoc11/test/.
strFileName:文件名稱。
overwrite：如果文件在文檔庫中已經存在，是否進行覆蓋。
$select:odata查詢關鍵字，進行篩選字段，這里是在文件上傳成功后，返回該文件的相關信息。
文件下載
文件下載api
string loadApi = "GetFileByServerRelativeUrl('" + serverRelativeUrl + "')/$value";
serverRelativeUrl:文件的相對路徑，比如：/server/libdoc11/test/1.txt
文件拷貝
string strCopyApi = "GetFileByServerRelativeUrl('" + strSourceUrl + "')/copyto(strnewurl='" + strTargetUrl + "',boverwrite=true)";
strSourceUrl:拷貝文件的相對路徑，比如：/server/libdoc11/test/1.txt
strTargetUrl：目標路徑，比如：比如：/server/libdoc11/test2/1.txt
boverwrite:是否覆蓋
文件剪切
string strMoveToApi = "GetFileByServerRelativeUrl('" + strSourceUrl + "')/moveto(newurl='" + strTargetUrl + "',flags=1)";
strSourceUrl:拷貝文件的相對路徑，比如：/server/libdoc11/test/1.txt
strTargetUrl：目標路徑，比如：比如：/server/libdoc11/test2/1.txt
flags:1是否覆蓋
刪除文件
刪除文件的接口，與獲取文件的接口一樣，只不過區別在發送的請求不通，一個是get請求，一個是delete請求。
string queryFileApi = "GetFileByServerRelativeUrl('" + serverRelativeUrl + "')";
string strFileApi = "GetFolderByServerRelativeUrl('" + strFileServerRelativeUrl + "')/Files?$filter=Name eq '" + strFileName + "'&$select=Name,ServerRelativeUrl,TimeCreated,TimeLastModified,Exists,Length";
上面兩個都是可以得，第二種是使用odata查詢$filter關鍵字進行篩選，文件名稱等於要刪除的文件名就可以了，並返回刪除的文件信息。
獲取文檔列表
string strFileApi = "GetFolderByServerRelativeUrl('" + strServerRelative + "')/Files?$orderby=TimeCreated desc&$select=Author/Title,ModifiedBy/Title,CheckInComment,Name,ServerRelativeUrl,TimeCreated,TimeLastModified,Exists,Length&$expand=Author/Title,ModifiedBy/Title"; string strFolderApi = "GetFolderByServerRelativeUrl('" + strServerRelative + "')/Folders?$filter=Name ne 'Forms'&$select=Name,ServerRelativeUrl,ItemCount";
上面的是獲取某個文檔庫的文件列表。並返回需要的屬性。下面的接口為獲取所有的文件夾，當然可以根據傳入的相對路徑，獲取子目錄中的所有文件夾，其中Forms為默認隱藏的目錄，可以將其過濾掉，這里是篩選所有不文件夾名字不等於Forms的目錄。
注意
在返回文件的創建者與編輯者時，需要使用Author/Title,ModifiedBy/Tilte，因為Author與ModifiedBy在sharepoint端是User對象，並且這時候你會發現這樣仍不能正確的顯示創建者與編輯者，這時候就需要用到odata查詢的$expand關鍵字。
創建文件夾
string strCreateFolderApi = "folders/add('" + serverRelativeUrl + "/" + folderName + "')";
serverRelativeUrl：相對路徑，就是要在哪兒創建文件夾。

其中url為文檔庫的站點地址，比如文檔庫DocLib10的地址為Http://www.bb.com/site/DocLib10/AllItems.aspx.則Url為Http://www.bb.com/site/DocLib10。
買一送一接口
最后再奉上一個查詢某個文檔庫信息的接口
string strDocApi = "lists?$filter=((EntityTypeName eq '" + strEntityName + "' or substringof('" + strEntityName + "',DocumentTemplateUrl)) and BaseTemplate eq 101)&$select=Id,EntityTypeName,ParentWebUrl,Title,BaseTemplate";
使用odata查詢，文檔庫的BaseTemplate為101，這樣也可以獲取所有的文檔庫列表。
substringof函數為：屬性值中包含某個字符串。以該接口為例,DocumentTemplateUrl中包含strEntityName的文檔庫。
總結
這里將查詢到的，以及用到的接口總結在這里。在使用的時候，各種參數導致的請求失敗，當時頭都大了。而msdn上面大多都是js的，而且沒有詳細的demo，只能一個個的嘗試。通過文檔庫的rest api對sharepoint中的List，Item也有一個了解，知道一些操作該去怎么實現。使用場景：移動端集成sharepoint。
