You must have WRITE permissions on a bucket to add // an object to it. Amazon S3 never adds partial objects; if you receive a success // response, Amazon S3 added the entire object to the bucket. Amazon S3 is a // distributed system. If it receives multiple write requests for the same object // simultaneously, it overwrites all but the last object written. Amazon S3 does // not provide object locking; if you need this, make sure to build it into your // application layer or use versioning instead. To ensure that data is not // corrupted traversing the network, use the Content-MD5 header. When you use this // header, Amazon S3 checks the object against the provided MD5 value and, if they // do not match, returns an error. Additionally, you can calculate the MD5 while // putting an object to Amazon S3 and compare the returned ETag to the calculated // MD5 value. // // * To successfully complete the PutObject request, you must have the // s3:PutObject in your IAM permissions. // // * To successfully change the objects acl // of your PutObject request, you must have the s3:PutObjectAcl in your IAM // permissions. // // * The Content-MD5 header is required for any request to upload an // object with a retention period configured using Amazon S3 Object Lock. For more // information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview // (https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock-overview.html) in // the Amazon S3 User Guide. // // Server-side Encryption You can optionally request // server-side encryption. With server-side encryption, Amazon S3 encrypts your // data as it writes it to disks in its data centers and decrypts the data when you // access it. You have the option to provide your own encryption key or use Amazon // Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information, // see Using Server-Side Encryption // (https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingServerSideEncryption.html). // If you request server-side encryption using Amazon Web Services Key Management // Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more // information, see Amazon S3 Bucket Keys // (https://docs.aws.amazon.com/AmazonS3/latest/dev/bucket-key.html) in the Amazon // S3 User Guide. Access Control List (ACL)-Specific Request Headers You can use // headers to grant ACL- based permissions. By default, all objects are private. // Only the owner has full access control. When adding a new object, you can grant // permissions to individual Amazon Web Services accounts or to predefined groups // defined by Amazon S3. These permissions are then added to the ACL on the object. // For more information, see Access Control List (ACL) Overview // (https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html) and Managing // ACLs Using the REST API // (https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-using-rest-api.html). If // the bucket that you're uploading objects to uses the bucket owner enforced // setting for S3 Object Ownership, ACLs are disabled and no longer affect // permissions. Buckets that use this setting only accept PUT requests that don't // specify an ACL or PUT requests that specify bucket owner full control ACLs, such // as the bucket-owner-full-control canned ACL or an equivalent form of this ACL // expressed in the XML format. PUT requests that contain other ACLs (for example, // custom grants to certain Amazon Web Services accounts) fail and return a 400 // error with the error code AccessControlListNotSupported. For more information, // see Controlling ownership of objects and disabling ACLs // (https://docs.aws.amazon.com/AmazonS3/latest/userguide/about-object-ownership.html) // in the Amazon S3 User Guide. If your bucket uses the bucket owner enforced // setting for Object Ownership, all objects written to the bucket by any account // will be owned by the bucket owner. Storage Class Options By default, Amazon S3 // uses the STANDARD Storage Class to store newly created objects. The STANDARD // storage class provides high durability and high availability. Depending on // performance needs, you can specify a different Storage Class. Amazon S3 on // Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage // Classes // (https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html) in // the Amazon S3 User Guide. Versioning If you enable versioning for a bucket, // Amazon S3 automatically generates a unique version ID for the object being // stored. Amazon S3 returns this ID in the response. When you enable versioning // for a bucket, if Amazon S3 receives multiple write requests for the same object // simultaneously, it stores all of the objects. For more information about // versioning, see Adding Objects to Versioning Enabled Buckets // (https://docs.aws.amazon.com/AmazonS3/latest/dev/AddingObjectstoVersioningEnabledBuckets.html). // For information about returning the versioning state of a bucket, see // GetBucketVersioning // (https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketVersioning.html). // Related Resources // // * CopyObject // (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CopyObject.html) // // * // DeleteObject // (https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObject.html) func (c *Client) PutObject(ctx context.Context, params *PutObjectInput, optFns ...func(*Options)) (*PutObjectOutput, error) { if params == nil { params = &PutObjectInput{} } result, metadata, err := c.invokeOperation(ctx, "PutObject", params, optFns, c.addOperationPutObjectMiddlewares) if err != nil { return nil, err } out := result.(*PutObjectOutput) out.ResultMetadata = metadata return out, nil } type PutObjectInput struct { // The bucket name to which the PUT action was initiated.
