keystone cannot use the command curl

dear all:

   i installed keystone using clone,when i use the command of

curl -d '{"auth": {"tenantName": "service", "passwordCredentials":{"username": "glance", "password": "mypasswd"}}}' -H "Content-type: application/json" http://192.168.77.105:35357/v2.0/tokens | python -mjson.tool

there is an error,{
    "error": {
        "code": 500,
        "message": "An unexpected error prevented the server from fulfilling your request. unsupported format character 't' (0x74) at index 33",
        "title": "Internal Server Error"
    }
}
this is my keystone.conf
