从SharePoint下载文件 [英] Download file from SharePoint
问题描述
我正在使用SharePoint的REST API查询公司用户的Office 365 SharePoint网站中托管的文件.
I'm using the REST APIs of SharePoint to query the files hosted inside a corporate user's Office 365 SharePoint site.
我已使用OAuth对用户进行身份验证并授权了该应用，如下所述: http://msdn.microsoft.com/en-us/library/azure/dn645542.aspx
I have used OAuth to authenticate the user and authorize the the app, as described here: http://msdn.microsoft.com/en-us/library/azure/dn645542.aspx
我能够通过GET请求成功查询API: https://XXXXXXX.sharepoint.com/sites/xxxxx/xxxxx/myfoldername /_api/文件 (您所期望的作为Authorization标头的请求设置为'Bearer'.)
I am able to successfully query the API with a GET request on: https://XXXXXXX.sharepoint.com/sites/xxxxx/xxxxx/myfoldername/_api/files (the request as the Authorization header set to 'Bearer ', as you'd expect.)
上面的查询为我提供了以下JSON结果:
The above query gives me the following JSON result:
{
"odata.metadata" = "https://xxxxxxxxx.sharepoint.com/sites/xxxxxxxxx/xxxxxxxxx/myfoldername/_api/$metadata#SP.ApiData.Files";
value = (
{
CreatedBy = {
Id = 1;
Name = "Test";
Puid = xxxxx;
};
ETag = "\"{hsdglksjfldkasnfldasknk},4\"";
Id = JKLBbiuuu908yYHhh89YBn9n9ynynYUN;
LastModifiedBy = {
Id = 1;
Name = "XXXXX";
Puid = XXXXXXXXXXX;
};
Name = "videofile.wmv";
Size = 56492358;
TimeCreated = "2013-09-23T05:16:44Z";
TimeLastModified = "2013-09-23T05:28:42Z";
Url = "https://xxxxxxxxx.sharepoint.com/sites/xxxxxxxxx/xxxxxxxxx/myfoldername/Shared Documents/videofile.wmv";
"odata.editLink" = "Web/Lists(guid’9568472598-2c28-489BF2-a1ae-kfjdasfkjb)/files(‘jkbvasdjfbakfndasnMNBBAMnsaldfan)";
"odata.id" = "https://xxxxxxxxx.sharepoint.com/sites/xxxxxxxxx/xxxxxxxxx/myfoldername/_api/Web/Lists(guid’987795-gfkjhghs-ty42398yhfo’)/files('jkbvasdjfbakfndasnMNBBAMnsaldfan')";
"odata.type" = "MS.FileServices.File";
})
}
(请记住，上面的内容实际上不是JSON，而是从JSON解析器输出的文本)
(Bear in mind the above is not actually JSON, but text output from a JSON parser)
在上面的结果中，我在value部分中得到了一个文件数组.为了说明起见，我将此阵列缩减为一个项目.
In the result above, I get an array of files inside the value part. I have cut this array down to one item for illustrative purposes.
您将看到每个项目代表文件的元数据.有一个名为Url的属性.然后，我用它来尝试下载文件.我创建一个HTTP请求，在Authorization标头后附加Bearer <access_token>，但是，响应始终是HTTP 401 UNAUTHORIZED.
You'll see each item represents a file's meta data. There's a property called Url; I then use this to attempt to download the file. I create an HTTP request, append the Authorization header with Bearer <access_token>, however, the response is always an HTTP 401 UNAUTHORIZED.
请注意:我正在编写的软件实际上是使用AFNetworking 2的AFHTTPRequestOperationManager在Objective-C中进行的.
Please note: the software I'm writing is actually in Objective-C using AFNetworking 2's AFHTTPRequestOperationManager.
有人知道我可以如何实际下载文件吗?我已经在文档中看到了对某些名为"contentUrl"的属性的引用，但未提供此属性.
Does anyone know how I can actually download the file? I have seen references to some property called 'contentUrl' in the docs, but this property is not supplied.
谢谢 克里斯(Kris)

推荐答案
您是否正在使用API的v1?从您的端点看来，您似乎正在使用预览(v1已于2周前发布；我们的文档页面上可能仍然有过时的参考，如果您遇到任何问题，请告知我们)
Are you using the v1 of the API? From your endpoint it seems like you're using preview (v1 was released 2 weeks ago; we might still have outdated references on our documentation pages, please let us know if you come across any)
示例:
获取https://{tenant} .sharepoint.com/{site-path}/_api/v1.0/Files/{file-id}/content
GET https://{tenant}.sharepoint.com/{site-path}/_api/v1.0/Files/{file-id}/content
This is the URL of the documentation section that shows you how to download a file: http://msdn.microsoft.com/en-us/office/office365/api/files-rest-operations#FileresourceDownloadafile
让我知道您是否还有其他问题.
Let me know if you have any other issues.
