土耳其语上的 AWS S3 SDKv2 和图像上传 ios

Question

我使用代码将图像上传到 AWS S3：

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:pathComp];
    [UIImageJPEGRepresentation(myImage,0.9) writeToFile:filePath atomically:NO];
    filePath = [NSString stringWithFormat:@"file:///private%@", filePath];
    NSURL* fileUrl = [NSURL URLWithString:filePath];
    AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
    uploadRequest.key = key;
    uploadRequest.body = fileUrl;
    uploadRequest.contentType = @"image/jpeg";

上传正常，但在mechanical turk中无法打开预览

Answer 1

使用 NSURL 创建文件 URL 时，您应该使用 + fileURLWithPath:。你应该改变这一行

NSURL* fileUrl = [NSURL URLWithString:filePath];

到

NSURL* fileUrl = [NSURL fileURLWithPath:filePath];

您应该仔细检查文件是否已使用 AWS Management Console 成功上传。

此外，默认情况下，所有 Amazon S3 资源（存储桶、对象和相关子资源）都是私有的：只有资源所有者（创建它的 AWS 账户）才能访问该资源。可以修改ACL来改变权限。
