写在前面
最近对文档库的知识点进行了整理，也就有了这篇文章，当时查找这些接口，并用在实践中，确实废了一些功夫，也为了让更多的人走更少的弯路。

WebHttpRequest在sharepoint文档库中的使用
[sharepoint]修改Item或者File的Author和Editor
文件上传
通过rest api上传到sharepoint文档库。
上传文件api
string strApi = "GetFolderByServerRelativeUrl('" + strFileServerRelativeUrl + "')/Files/Add(url='" + strFileName + "',overwrite=true)?$select=Name,ServerRelativeUrl,TimeCreated,TimeLastModified,Exists,Length";
strFileServerRelativeUrl：文件在sharepoint文档库中的相对路径，比如：/server/libdoc11/test/.
strFileName:文件名称。
overwrite：如果文件在文档库中已经存在，是否进行覆盖。
$select:odata查询关键字，进行筛选字段，这里是在文件上传成功后，返回该文件的相关信息。
文件下载
文件下载api
string loadApi = "GetFileByServerRelativeUrl('" + serverRelativeUrl + "')/$value";
serverRelativeUrl:文件的相对路径，比如：/server/libdoc11/test/1.txt
文件拷贝
string strCopyApi = "GetFileByServerRelativeUrl('" + strSourceUrl + "')/copyto(strnewurl='" + strTargetUrl + "',boverwrite=true)";
strSourceUrl:拷贝文件的相对路径，比如：/server/libdoc11/test/1.txt
strTargetUrl：目标路径，比如：比如：/server/libdoc11/test2/1.txt
boverwrite:是否覆盖
文件剪切
string strMoveToApi = "GetFileByServerRelativeUrl('" + strSourceUrl + "')/moveto(newurl='" + strTargetUrl + "',flags=1)";
strSourceUrl:拷贝文件的相对路径，比如：/server/libdoc11/test/1.txt
strTargetUrl：目标路径，比如：比如：/server/libdoc11/test2/1.txt
flags:1是否覆盖
删除文件
删除文件的接口，与获取文件的接口一样，只不过区别在发送的请求不通，一个是get请求，一个是delete请求。
string queryFileApi = "GetFileByServerRelativeUrl('" + serverRelativeUrl + "')";
string strFileApi = "GetFolderByServerRelativeUrl('" + strFileServerRelativeUrl + "')/Files?$filter=Name eq '" + strFileName + "'&$select=Name,ServerRelativeUrl,TimeCreated,TimeLastModified,Exists,Length";
上面两个都是可以得，第二种是使用odata查询$filter关键字进行筛选，文件名称等于要删除的文件名就可以了，并返回删除的文件信息。
获取文档列表
string strFileApi = "GetFolderByServerRelativeUrl('" + strServerRelative + "')/Files?$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";
上面的是获取某个文档库的文件列表。并返回需要的属性。下面的接口为获取所有的文件夹，当然可以根据传入的相对路径，获取子目录中的所有文件夹，其中Forms为默认隐藏的目录，可以将其过滤掉，这里是筛选所有不文件夹名字不等于Forms的目录。
注意
在返回文件的创建者与编辑者时，需要使用Author/Title,ModifiedBy/Tilte，因为Author与ModifiedBy在sharepoint端是User对象，并且这时候你会发现这样仍不能正确的显示创建者与编辑者，这时候就需要用到odata查询的$expand关键字。
创建文件夹
string strCreateFolderApi = "folders/add('" + serverRelativeUrl + "/" + folderName + "')";
serverRelativeUrl：相对路径，就是要在哪儿创建文件夹。

其中url为文档库的站点地址，比如文档库DocLib10的地址为Http://www.bb.com/site/DocLib10/AllItems.aspx.则Url为Http://www.bb.com/site/DocLib10。
买一送一接口
最后再奉上一个查询某个文档库信息的接口
string strDocApi = "lists?$filter=((EntityTypeName eq '" + strEntityName + "' or substringof('" + strEntityName + "',DocumentTemplateUrl)) and BaseTemplate eq 101)&$select=Id,EntityTypeName,ParentWebUrl,Title,BaseTemplate";
使用odata查询，文档库的BaseTemplate为101，这样也可以获取所有的文档库列表。
substringof函数为：属性值中包含某个字符串。以该接口为例,DocumentTemplateUrl中包含strEntityName的文档库。
总结
这里将查询到的，以及用到的接口总结在这里。在使用的时候，各种参数导致的请求失败，当时头都大了。而msdn上面大多都是js的，而且没有详细的demo，只能一个个的尝试。通过文档库的rest api对sharepoint中的List，Item也有一个了解，知道一些操作该去怎么实现。使用场景：移动端集成sharepoint。
