写在前面
刚入职一家新公司，在对接app的时候需要获取到某公司的sharepoint上面的文档库，获取文档库列表，团队文档库中的文件和文件夹列表，个人文档库中的文件文件夹列表，及在app端进入文件夹的时候需要获取该文件夹下的文件及文件夹列表，对文件的上传下载等操作。
对rest api的使用，完全是小白，具体也不知道怎么实现，在编写过程中查找了很多资料，发现这方面的资料极其少，也有可能是对自己对这个技术完全的不了解，所以在查找方向上面有问题。最后算是实现了上面的功能，这里做一下记录，以及提供一些参考资料。
实现过程
在如果注册app以及注册发布者的操作步骤，可以参考我之前的一篇文章：Rest API的简单应用，这里介绍了如何注册app和发布者的操作步骤，也包括了如何使用高安全的访问方式。希望对你有所帮助。项目的简单描述，本项目实现方式是一个server to server的方式，在app请求iis上面部署的接口，然后该iis服务器再去请求sharepoint服务器的api，获取文档库的相关信息。流程是大概这样的一个流程。
注册的发布者：所有的操作可以使用同一个发布者。
团队文档库：可以使用同一个ClientID
个人文档库：每一个人对应一个ClientID。
查询方式使用了OData的方式，关于OData的查询方式，可以参考这篇文章

查询
查询单个文件的信息
/// <summary>
/// 根据文件在服务端的相对url获取文件信息
/// </summary>
/// <param name="serverRelativeUrl">文件在服务端的相对url</param>
/// <returns>文件信息的json</returns>
public string GetFileInfoByRelativeUrl(string serverRelativeUrl)
{
///Personal/chenwd/Documents/Shared with Everyone
string queryFileApi = "GetFileByServerRelativeUrl('" + serverRelativeUrl + "')";
string filter = "?$select=" + new Document.Core.Model.Document().ToString();
if (_documentType == Model.DocumentType.Personal)
{
RequestHelper.ClientID = _dicMapping[_userName];
}
string strFileJson = RequestHelper.RequestGet(_userName, _appUrl, queryFileApi + filter, _documentType);
return strFileJson.ToJson("");
}
这里将文件信息封装成为一个类，并重写了tostring方法，方便操作。
/// <summary>

/// </summary>

{

public string UIVersionLabel { get; set; }
public override string ToString()
{
Type type = this.GetType();
PropertyInfo[] pros = type.GetProperties();
string str = string.Empty;
foreach (var item in pros)
{
str += item.Name + ",";
}
return str.TrimEnd(',');
}
}
然后使用Odata查询，获取需要的字段的值。

总结
在写接口的时候，在文件上传的地方，卡了一天的时间，也就是昨天的时候，突然查询了Miscrosoft.SharePoint.Client下的File类，才在网上看到那种实现方式，在群里也问了一些搞sharepoint的朋友，说那种方式操作起来更简单一些，如果用Msdn中提到的那种方式使用Post提交数据，需要在请求头中加一些参数。试了很多次无果，不得不放弃了。
