I am trying to create/upload image in openstack using python urllib2 library. Request : sampleResquest = urllib2.Request('http://192.168.1.112:9292/v1/images') sampleResquest.add_header("X-Auth-Token", tokenID) sampleResquest.add_header("Accept-Encoding", "gzip, deflate") sampleResquest.add_header("x-image-meta-container_format", "ami") sampleResquest.add_header("Accept","*/*") sampleResquest.add_header("Content-Type", "application/json") sampleResquest.add_header("X-Image-Meta-Name", "testImage") sampleResquest.add_header("x-image-meta-disk_format", "ami") sampleResquest.add_header("x-image-meta-is_public", "True") sampleResquest.add_header("X-Image-Meta-Status", "active") sampleResquest.add_header("X-Image-Meta-Size", "13147648") sampleResquest.add_header("name", "fileUpload") sampleResquest.add_header("filename", "cirros-032") sampleResquest.add_header("Accept-Language", "en-US,en;q=0.8") jsonPayload = json.dumps({"image":{"name": "My Image" }}) url_req = urllib2.urlopen(sampleResquest,jsonPayload) print json.loads(url_req.read()) Response: urllib2.HTTPError: HTTP Error 400: Bad Request Is there something i am missing ?? Could you suggest any correction ?
