putObject 异常。可能是由于 publicRead

Question

在执行putObject 时，我遇到了无法使用 try/catch 捕获的未捕获异常（可能是因为它在不同的线程上运行）。问题是间歇性的，我还没有找到模式。当我将 ACL 设置为 publicRead 时，可能会开始出现此问题。

我使用的是最新的 SDK 版本 1.7.1。

代码如下：

AmazonS3Client *S3 = [[AmazonS3Client alloc] initWithAccessKey:kAWSAccessKey withSecretKey:kAWSSecretKey];
S3.endpoint = [AmazonEndpoints s3Endpoint:US_WEST_2];
S3PutObjectRequest *S3POR = [[S3PutObjectRequest alloc] initWithKey:imageKey inBucket:kS3SignatureBucket];
S3POR.delegate = self;
S3POR.cannedACL = [S3CannedACL publicRead];
S3POR.contentType = @"image/png";
S3POR.data = UIImagePNGRepresentation(imageData);
[S3 putObject:S3POR];

我不知道您问题的答案，但您可以尝试使用我的代码：

AmazonS3Client *s3Client = [ [ AmazonS3Client alloc ] initWithAccessKey:strAccessKey withSecretKey:strSecretKey ];
s3Client.endpoint = [ AmazonEndpoints s3Endpoint:EU_WEST_1 ];
s3Client.maxRetries = 1;
s3Client.timeout = 60;

S3TransferManager *s3TransferManager = [ [ S3TransferManager alloc ] init ];
s3TransferManager.operationQueue.maxConcurrentOperationCount = 2;
s3TransferManager.s3 = s3Client;

NSString *keyImage = //... here I generate a key

S3PutObjectRequest *putObjectRequest = [ [ S3PutObjectRequest alloc ] initWithKey:keyImage inBucket:self.s3BucketName ];
putObjectRequest.contentType = @"image/jpeg";
putObjectRequest.data = UIImageJPEGRepresentation( image, 0.5f );
putObjectRequest.cannedACL = [ S3CannedACL publicRead ];

putObjectRequest.delegate = self;
[ s3TransferManager upload:putObjectRequest ];

在上传完成之前不要忘记保持对 AmazonS3Client 和 S3TransferManager 的强引用！
