IOS 使用FederationToken上传文件， 未得到 tokenSTS 上传文件却不报错

credentialProvider 构造代码：

+(void)initOSSClient {
    
       id<OSSCredentialProvider> credential2 = [[OSSFederationCredentialProvider alloc] initWithFederationTokenGetter:^OSSFederationToken * {
        NSURL * url = [NSURL URLWithString:@"http://192.168.0.100:8080/xxx/];
        NSURLRequest * request = [NSURLRequest requestWithURL:url];
        OSSTaskCompletionSource * tcs = [OSSTaskCompletionSource taskCompletionSource];
        NSURLSession * session = [NSURLSession sharedSession];
        NSURLSessionTask * sessionTask = [session dataTaskWithRequest:request
                                                    completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
                                                        if (error) {
                                                            [tcs setError:error];
                                                            return;
                                                        }
                                                        [tcs setResult:data];
                                                    }];
        [sessionTask resume];
        [tcs.task waitUntilFinished];
        if (tcs.task.error) {
            NSLog(@"get token error: %@", tcs.task.error);
            return nil;
        } else {
            NSDictionary * object = [NSJSONSerialization JSONObjectWithData:tcs.task.result
                                                                    options:kNilOptions
                                                                      error:nil];
            OSSFederationToken * token = [OSSFederationToken new];
            NSDictionary *tempobject=[object objectForKey:@"Federation"];
            token.tAccessKey = [tempobject objectForKey:@"accesskeyid"];
            token.tSecretKey = [tempobject objectForKey:@"accesskeysecret"];
            token.tToken = [tempobject objectForKey:@"securitytoken"];
            token.expirationTimeInGMTFormat = [tempobject objectForKey:@"expiration"];
            NSLog(@"get token: %@", token);
            //2015-11-03T08:51:05Z
            return token;
        }
    }];
    
    
    OSSClientConfiguration * conf = [OSSClientConfiguration new];
    conf.maxRetryCount = 2;
    conf.timeoutIntervalForRequest = 30;
    conf.timeoutIntervalForResource = 24 * 60 * 60;
    
    client = [[OSSClient alloc] initWithEndpoint:endPoint credentialProvider:credential2 clientConfiguration:conf];
}

            [FileTools copyFile:sourcepath toPath: topath];
        } else {
            
            NSLog(@"upload 文件 %d failed, error: %@" ,i, putTask.error);
            uploadresult=0;
             break;
  
        }
        
    }
    //回调返回上传状态
    handle(uploadresult);
    }

    

-------------------------

1.看这log ,就是无法得到 token报错 ：get token error:
2. 但是上传时却显示成功，因为 task.error为空

  if (!putTask.error) {
            
            NSLog(@"upload 文件 %d success!",i);
            //上传成功，将文件

credentialProvider的构造代码贴一下？

如果里面返回token为nil的话，是会报错的：upload object failed, error: Error Domain=com.aliyun.oss.clientError Code=1 "(null)" UserInfo={ErrorMessage=Can't get a federation token}。

-------------------------

那问下，你说的 “获取OSSFederationToken的服务端程序关掉” 之后，确认[[OSSFederationCredentialProvider alloc] initWithFederationTokenGetter:^OSSFederationToken * {...} 的 OSSFederationToken Block一直返回nil吗？

可以加一句话打印下。我这边确认如果block返回nil，是会报错的。

麻烦确认下sdk版本

建议提交工单吧，把能复现的demo提交给客服处理。或者，把能复现的demo打包上传，这里贴链接我去下载来试一下。
