Cannot create an object with a trailing slash, eg foo/ #1909
Description
Describe the bug
When I try to create file with a trailing slash, eg using the following code, the object is created in s3 without a trailing slash. Using aws s3api, or using the AWS web console, I can create an object with a trailing slash correctly (i.e. represents an empty folder. I have a use-case for this).
func createFolder(in bucketName: String, at path: String) async throws {
let normalizedBucketName = normalizeBucketName(bucketName)
let normalizedPath = path.hasSuffix("/") ? path : path + "/"
print("normalizedPath", normalizedPath)
let input = PutObjectInput(
body: .data(Data()),
bucket: normalizedBucketName,
key: normalizedPath
)
do {
_ = try await s3Client.putObject(input: input)
} catch {
print("Error creating folder: \(error)")
throw error
}
}
Expected Behavior
Expect to create an empty file with a trailing slash, which is interpreted by some UIs, such as aws web console, as an emptyt folder.
Current Behavior
The traling slash is truncated from the object's key, so eg the object foo/ is created as foo.
Reproduction Steps
Run the following code, with a bucket you have write access to, and a pth of 'foo/'. In AWS Web Console, you can see that the file is created with name foo instead of foo/
func createFolder(in bucketName: String, at path: String) async throws {
let normalizedBucketName = normalizeBucketName(bucketName)
let normalizedPath = path.hasSuffix("/") ? path : path + "/"
print("normalizedPath", normalizedPath)
let input = PutObjectInput(
body: .data(Data()),
bucket: normalizedBucketName,
key: normalizedPath
)
do {
_ = try await s3Client.putObject(input: input)
} catch {
print("Error creating folder: \(error)")
throw error
}
}
Possible Solution
I hypothesize that the library is removing trailing slashes from object paths.
