Tornado RESTful PUT处理程序方法未获取请求参数

Question

我正在尝试对RESTful API进行单元测试。这是我的API：

class BaseHandler(tornado.web.RequestHandler):                    
    def __init__(self, *args, **kwargs):                          
        tornado.web.RequestHandler.__init__(self, *args, **kwargs)
        self.log = self.application.log                           
        self.db = self.application.db                             

class ProductHandler(BaseHandler):
    @tornado.web.removeslash
    def put(self, id = None, *args, **kwargs):
        try:
            self.log.info("Handling PUT request")                                                             
            if not id:                                                                                                      
                raise Exception('Object Id Required')                                                                        
            id = { '_id' : id }                                                                                                                            
            new_values = dict()                                                                                             
            name = self.get_argument('name', None)                                                                          
            description = self.get_argument('description', None)                                                            
            if name:                                                                                                        
                new_values['name'] = name                                                                                   
            if description:                                                                                                 
                new_values['description'] = description                                                                     
            self.db.products.update(id, new_values, safe = True)                                                                                                               
        except:
            self.log.error("".join(tb.format_exception(*sys.exc_info())))                                                   
            raise                                                                                                           

 class Application(tornado.web.Application):                         
     def __init__(self, config_path, test = False, *args, **kwargs): 
         handlers = [                                                
             (r"/product/?(.*)", ProductHandler),                    
         ]                                                           
         settings = dict(debug=True)                                 
         tornado.web.Application.__init__(self, handlers, **settings)
         self.log = logging.getLogger(__name__)                      
         self.config = ConfigParser()                                
         self.config.read(config_path)                               
         self.mongo_connection = Connection(                         
             host = self.config.get('mongo','host'),                 
             port = self.config.getint('mongo','port'),              
         )                                                           
         if test:                                                    
             db_name = self.config.get('test', 'mongo.db')           
         else:                                                       
             db_name = self.config.get('mongo', 'db')                
         self.log.debug("Using db:  %s" % db_name)                   
         self.db = self.mongo_connection[db_name]                    

但是，这是我的问题：处理程序没有看到名称或描述参数。:(

有什么建议么？

作为解决方法，我在 request.body 中找到了它们并手动解析了编码的参数。这有点烦人，但它确实有效。

new_values = urlparse.parse_qs(self.request.body)

# values show as lists with only one item
for k in new_values:                             
    new_values[k] = new_values[k][0]
