s3 iOS中的Bucket图像上传问题（Objective C）

Question

我试图将图像从我的Xcode项目上传到s3存储桶，这是第一次它完全正常工作但是在上传一个图像之后它每次出错都会给我错误

AWSiOSSDK v2.4.12 [错误] AWSCredentialsProvider.m行：577 | __44- [AWSCognitoCredentialsProvider凭证] _block_invoke.353 | 无法刷新。 错误是[错误域= com.amazonaws.AWSCognitoIdentityErrorDomain Code = 10“（null）”UserInfo = {__ type = ResourceNotFoundException，message = IdentityPool'us-west-2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'not found。}]

我正在使用的代码就是这个

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.

AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc]
                                                      initWithRegionType:AWSRegionUSEast1
                                                      identityPoolId:@"us-west-2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"];

AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1 credentialsProvider:credentialsProvider];

[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
return YES;}

-(void)uplaodImageToS3 :(NSString *)userId
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:[NSString stringWithFormat:@"user_%@.png", userId]];

    NSData *imageData = UIImagePNGRepresentation(uploadedImage);
    [imageData writeToFile:path atomically:YES];

    NSURL *url = [[NSURL alloc] initFileURLWithPath:path];

    _uploadRequest = [AWSS3TransferManagerUploadRequest new];
    _uploadRequest.bucket = @"dellonybucket";
    _uploadRequest.ACL = AWSS3ObjectCannedACLPublicRead;
    _uploadRequest.key = [NSString stringWithFormat:@"images/user_%@.png", userId];
    _uploadRequest.contentType = @"image/png";
    _uploadRequest.body = url;


    __weak RegistrationViewController *weakSelf = self;

    _uploadRequest.uploadProgress = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend){

        dispatch_sync(dispatch_get_main_queue(), ^{

            weakSelf.sizeUplaoded = totalBytesSent;
            weakSelf.filesize = totalBytesExpectedToSend;
            [weakSelf update];

        });

    };

    AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];
    [[transferManager upload:_uploadRequest]continueWithExecutor:[AWSExecutor mainThreadExecutor] withBlock:^id _Nullable(AWSTask * _Nonnull task) {
        if (task.error) {

            //NSLog(@"%@",task.error);
            [self hideHud];
            [self alertView:@"Image uplaoding failed please try again." title:@"Unsuccessfull"];

               }

               if (task.result) {
                   //AWSS3TransferManagerUploadOutput *uploadOutput = task.result;
                   [self hideHud];
                   [self alertView:@"User registerd successfully." title:@"Successfull"];


               }
        return nil;
    }];
}

看起来你正在告诉凭证提供者查看us-east-1，但你的身份池在us-west-2中。 因为它在us-east-1中不存在，所以你得到的资源没有找到错误。

如果您更新AWSRegionUSEast1区域，那么您应该很高兴。
