# Request Files { #request-files }

You can define files to be uploaded by the client using `File`.

/// info

To receive uploaded files, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console

	err = decoder.Decode(newResponse)
	c.Assert(err, nil)
	c.Assert(len(newResponse.UploadID) > 0, true)
	// uploadID to be used for rest of the multipart operations on the object.
	uploadID := newResponse.UploadID

	// content for the part to be uploaded.
	buffer1 := bytes.NewReader([]byte("hello world"))
	// HTTP request for the part to be uploaded.

	// ChecksumAlgorithm if set
	ChecksumAlgorithm string

	// ChecksumType if set
	ChecksumType string
}

// Lookup - returns if uploadID is valid
func (lm ListMultipartsInfo) Lookup(uploadID string) bool {
	for _, upload := range lm.Uploads {
		if upload.UploadID == uploadID {
			return true
		}
	}
	return false
}

// ListMultipartsInfo - represents bucket resources for incomplete multipart uploads.

# Request Forms and Files { #request-forms-and-files }

You can define files and form fields at the same time using `File` and `Form`.

/// info

To receive uploaded files and/or form data, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

	}
	uploadID := res.UploadID

	abortTestCases := []struct {
		bucketName      string
		objName         string
		uploadID        string
		expectedErrType error
	}{
		{"--", object, uploadID, BucketNameInvalid{}},
		{"foo", object, uploadID, BucketNotFound{}},
		{bucket, object, "foo-foo", InvalidUploadID{}},
		{bucket, object, uploadID, nil},
	}

	}

	// Cleanup all uploaded parts.
	defer er.deleteAll(ctx, minioMetaMultipartBucket, er.getUploadIDDir(bucket, object, uploadID))

	// Validates if upload ID exists.
	_, _, err = er.checkUploadIDExists(ctx, bucket, object, uploadID, false)
	return toObjectErr(err, bucket, object, uploadID)

			uploadID:         uploadID,
			copySourceHeader: url.QueryEscape(SlashSeparator + bucketName + SlashSeparator + testObject),
			accessKey:        credentials.AccessKey,
			secretKey:        credentials.SecretKey,

			expectedRespStatus: http.StatusNotFound,
		},

		// Test case - 4.
		// Test case with valid byte range.
		{
			bucketName:       bucketName,
			uploadID:         uploadID,

  - New objects inherit the retention settings of the bucket object lock configuration automatically
  - Retention headers can be optionally set while uploading objects
  - Once objects are uploaded PutObjectRetention API can be called to change retention settings
- *MINIO_NTP_SERVER* environment variable can be set to remote NTP server endpoint if system time is not desired for setting retention dates.

### 3. Test your setup

To test this setup, access the MinIO server via browser or [`mc`](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart). You’ll see the uploaded files are accessible from the all the MinIO endpoints.

if err != nil {
 log.Fatalln(err)
}
log.Println("Uploaded", "my-objectname", " of size: ", n, "Successfully.")
