问题描述
我正在使用 BITS 协议将大文件上传到 OneDrive 。这是
I'm implementing uploading big files to OneDrive by using BITS protocol. Here is the documentation
我'我有以下问题。在我尝试创建会话后登录一段时间后，我收到401错误。以下是完整的回复：
I'm having the following issue. After a certain period of time of being logged in when I'm trying to create a session I'm receiving 401 error. Here's the complete response:
<NSHTTPURLResponse: 0x7d6ee0f0> { URL: https://cid-da1cedf5484811a9.users.storage.live.com/items/DA1CEDF5484811A9!373/IMG_0003.JPG } { status code: 401, headers {
"BITS-Packet-Type" = Ack;
"Content-Length" = 0;

P3P = "CP=\"BUS CUR CONo FIN IVDo ONL OUR PHY SAMo TELo\"";

这是我的请求的样子：

}
如果需要，我可以发布用于打开会话的代码，我不会现在发布，因为它非常大。
I can post code used to open session if you need, I don't post it now because it's pretty large.
好的，我想到的第一件事就是访问令牌已经过时了，我需要以某种方式更新它。但！就在我使用相同的访问令牌执行检索用户ID的请求之前：
OK, the first thing that comes to my mind is that access token has got outdated and I need to renew it somehow. BUT! Just before I perform request to retrieve user Id using the same access token:
- (void)retrieveUserId
{
NSString *urlString = [NSString stringWithFormat:@"https://apis.live.net/v5.0/me?access_token=%@", commonAccessToken];
NSURL *url = [NSURL URLWithString:urlString];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSURLSessionDataTask *task = [session dataTaskWithURL:url
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error){
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if (httpResponse.statusCode == 200)
{
NSLog(@"Response retrieving user id %@", httpResponse);
NSError *parsingError = nil;
NSDictionary *parsedDictionary = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&parsingError];
if (!parsingError)
{
commonUserId = parsedDictionary[@"id"];
[self createUploadRequest];
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
[self.delegate bitsClient:self didFailWithError:parsingError];
});
}
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
[self.delegate bitsClient:self didFailWithError:error];
});
}
}];
[task resume];
}
它有效。当我获得用户ID时，此访问令牌是正常的。但是你可以看到，与尝试打开会话时不同，访问令牌是作为url的一部分而不是作为头字段之一。我不确定它是否重要。到现在为止我无法解释这种行为。如果我退出并再次登录，那么它再次正常，我不再收到401错误，所以我真的应该更新令牌，但是怎么办呢？还有一件事让你知道 - 当我从 LiveConnectSession 获得访问令牌时，我会检查这个会话是否过期而不是。其到期属性晚于 [NSDate date] 。
And it works. This access token is OK when I get the user Id. But you can see that here unlike when trying to open a session the access token is put as a part of url, not as one of header fields. I'm not sure if it matters or not. By now I can't explain such a behaviour. If I logout and login again then it's OK again, I don't receive the 401 error anymore, so probably I really should renew the token, but how can it be done? One more thing for you to know - when I get the access token from LiveConnectSession I check if this session is expired and it's not. Its expires property is later than [NSDate date].
还有一件事让你知道 - 尽管我无法打开会话，如果我尝试使用上传文件，我的请求被401错误拒绝 Live SDK 的 LiveOperation 文件上传时没有任何错误。
Also one more thing for you to know - despite I'm not able to open session and my request is being rejected with 401 error if I try to upload files by using Live SDK's LiveOperation the files are uploaded without any error.
我想恢复：经过一段时间（似乎是24小时但我不确定）以 OneDrive身份登录用户我无法使用 BITS 协议上传文件，因为我收到401错误。同时会话似乎没有过期，我仍然可以使用 LiveOperation 上传文件。此外，我可以使用打开上传会话时使用的相同访问令牌轻松获取用户ID。如果我退出并再次登录，那么一切都像魅力一样，我可以创建会话和上传文件。
I want to resume: After a certain period (seems like it is 24 hours but I'm not sure) of being logged in as OneDrive user I become unable to upload files using BITS protocol because I receive 401 error. At the same time the session seems to be not expired and I can still upload files by using LiveOperation. Also I can easily get user id using the same access token which is used when opening an upload session. If I logout and login again then again everything works like charm and I'm able to create session and upload files.
似乎这就是我可以告诉你的全部内容，但如果您需要任何其他信息，请告诉我。任何帮助都非常感谢。
Seems like this is all that I can tell you, but if you need any additional info please tell me. Any help is extremely appreciated.
推荐答案
安德烈，我是php开发人员，这是我在php中所做的：
Andrey, i am php developer and here is what i am doing in php:
const API_URL = 'https://apis.live.net/v5.0/';
const INITAPIURL = 'https://login.live.com/oauth20_token.srf';
const URI_AUTHORIZE = 'https://login.live.com/oauth20_authorize.srf';
1）获取访问令牌并保存刷新令牌（下面的函数生成URL以重定向用户oAuth）
1) getting access token and saving refresh token (function below generate URL to redirect user for oAuth)
public function getAuthorizeUrl($cburl) {
$cburl=_SKYDRIVE_REDIRECT_URI;
return self::URI_AUTHORIZE.'?client_id='.urlencode(_SKYDRIVE_API_CLIENT_ID).'&scope='.urlencode('wl.offline_access wl.skydrive wl.skydrive_update wl.emails wl.contacts_skydrive wl.contacts_photos').'&response_type=code&redirect_uri='.urlencode($cburl);
}
2）每隔3300秒（访问令牌直播3600秒）我刷新直接在服务器上使用刷新令牌访问令牌（在浏览器中没有用户确认）
2) after every 3300 seconds (access token live for 3600 sec) i refresh access token with refresh token directly on server (without user confirmation in browser)
$r = $this->http(self::INITAPIURL, 'POST', array("grant_type" => "refresh_token", "client_id" => _SKYDRIVE_API_CLIENT_ID, "client_secret" => _SKYDRIVE_API_SECRET, "redirect_uri" => _SKYDRIVE_REDIRECT_URI, "refresh_token" => $this->refreshtoken));
3）我发送访问令牌作为带有curl的标头，用于我对API的所有请求（令牌刷新除外）上面）
3) i am sending access token as header with curl for all my requests to API (except token refresh above)
$headers[] = "Authorization: Bearer " . $this->token;
以上步骤在我使用BITS时工作（我刚刚在perl上实现了BITS协议使用，一切都是工作）
and above steps are working when i use BITS (i just implemented BITS protocol use on perl and everything is working)
PS谢谢你发了ID文件夹的URL，他们在文档中有错误的URL：）
P.S. Thank you that you posted URL of folder by ID they had wrong URL in documentation :)
