AWS S3將圖像上傳到Bucket iOS應用程序

Question

我是AWS新手，並將其用於iOS應用程序。

我正在嘗試將圖像從我的iOS應用程序上傳到名為“img.haraj.com.sa”的存儲桶。 當我上傳任何圖片時，它們不會顯示在桶中。 但是當我將目標更改為名為“haraj”的存儲桶時，它們會被上傳並顯示在存儲桶中。

這是政策：

{
  "Statement": [
    {
      "Sid": "**********hidden**********",
      "Action": [
        "s3:GetObject",
        "s3:PutObject"
      ],
      "Effect": "Allow",
      "Resource": [
       "arn:aws:s3:::haraj/*"
      ]
    }
  ]
}

我修改它來更改目標存儲桶。 我還創建了名為“img1.haraj.com.sa”的其他存儲桶並試圖上傳圖像，不幸的是它們也失敗了。

使用點（。）和沒有點的桶名稱似乎存在一些問題。 沒有圓點的存儲桶名稱適用於iOS應用程序，帶點的名稱不起作用。 我不確定。 但是我正面臨着這個問題。 我在應用程序代碼中沒有收到任何錯誤響應。

這是我的iOS應用實現的一部分：

- (void)postAdButtonPushed:(id)sender
{
    DLog(@"Post Ad")

    AmazonS3Client *s3Client = [[AmazonS3Client alloc] initWithAccessKey:AWS_ACCESS_KEY_ID withSecretKey:AWS_SECRET_KEY];
    s3Client.timeout = 240;

    NSString *bucketName = [NSString stringWithFormat:@"img.haraj.com.sa"];
    NSString *imageName = [NSString stringWithFormat:@"testimage.jpg"];

    S3PutObjectRequest *objReq = [[S3PutObjectRequest alloc] initWithKey:imageName inBucket:bucketName];
    objReq.contentType = @"image/jpeg";

    UIImage *testImageToUpload = [self.imagesToUpload objectAtIndex:0];

    NSData *imageData = UIImageJPEGRepresentation(testImageToUpload, 0.8);
    objReq.data = imageData;
    objReq.delegate = self;

    objReq.contentLength = [imageData length];

    [s3Client putObject:objReq];
}

- (void)request:(AmazonServiceRequest *)request didCompleteWithResponse:(AmazonServiceResponse *)response
{
    DLog(@"response: %@", response.description)
}

- (void)request:(AmazonServiceRequest *)request didFailWithError:(NSError *)error
{
    DLog(@"Req failed: %@", error.description)
}

我還在Amazon Forum上創建了一個主題： AWS將圖像上傳到Bucket iOS應用程序

任何幫助，將不勝感激。 謝謝！

我已經張貼到您的論壇帖子的響應這里 ，而是要總結，我相信你已經碰到了針對SDK中的一個bug，需要明確設置S3終點在那里你的水桶所在。

只是想要權衡，這是我工作的代碼片段

// #import <AWSS3/AWSS3.h>
// #import <AWSRuntime/AWSRuntime.h>
// then you should implement <AmazonServiceRequestDelegate>
// import those in your .h file and
// add the awss3 and awsruntime framework from the client
// download from Amazon
// myFace is the UIImage object

    AmazonS3Client *s3Client = [[AmazonS3Client alloc] initWithAccessKey:@"Key_Goes_here" withSecretKey:@"Secret_Goes_Here"];

    NSString *imageName = [NSString stringWithFormat:@"%@.png", @"cpa"];

    S3PutObjectRequest *objReq = [[S3PutObjectRequest alloc] initWithKey:imageName inBucket:@"bucket_name"];
    objReq.contentType = @"image/png";
    objReq.cannedACL   = [S3CannedACL publicRead];
    objReq.data = UIImagePNGRepresentation(myFace);
    objReq.delegate = self;

    [s3Client putObject:objReq];

這是委托方法：

-(void)request:(AmazonServiceRequest *)request didSendData:(long long)bytesWritten totalBytesWritten:(long long)totalBytesWritten totalBytesExpectedToWrite:(long long)totalBytesExpectedToWrite {
}

-(void)request:(AmazonServiceRequest *)request didReceiveResponse:(NSURLResponse *)response {
    NSLog(@"response! %@", response);
}

-(void)request:(AmazonServiceRequest *)request didCompleteWithResponse:(AmazonServiceResponse *)response {

}

-(void)request:(AmazonServiceRequest *)request didReceiveData:(NSData *)data {
    NSLog(@"data?");
}

-(void)request:(AmazonServiceRequest *)request didFailWithError:(NSError *)error {
    [self showAlertMessage:[error.userInfo objectForKey:@"message"] withTitle:@"Upload Error"];
}

如果您不想授予公共訪問權限，則還應在IAM中定義用戶，並將此代碼放入存儲桶策略中：

{
  "Version": "2012-10-17",
  "Id": "S3AccessPolicy",
  "Statement": [
    {
      "Sid": "GiveGetPutAccess",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::123456789012:user/YOUR_USER"
      },
      "Action": [
        "s3:GetObject",
        "s3:PutObject"
      ],
      "Resource": "arn:aws:s3:::YOUR_BUCKET/*"
    }
  ]
}
