Python 类型错误：未绑定方法'；方法名称'；必须使用'；类名'；实例作为第一个参数（改为获取str实例）

您好，我正在尝试为“电影数据库”API使用simpletmdb python包装，但我无法通过此问题

当我尝试创建对象并调用获取电影信息的方法时，我一直会遇到这个错误

in info 
response = TMDB._request('GET', path, params)
TypeError: unbound method _request() must be called with TMDB instance as first argument        (got str instance instead)

我调用它的代码是：

from tmdbsimple import TMDB

tmdb = TMDB('API_KEY')
movie = tmdb.Movies(603)
response = movie.info()
print movie.title

simpletmdb包装器的必要部分是，Movies类是TMDB的一个子类：

class TMDB:
   def __init__(self, api_key, version=3):
        TMDB.api_key = str(api_key)
        TMDB.url = 'https://api.themoviedb.org' + '/' + str(version)

    def _request(method, path, params={}, json_body={}):
        url = TMDB.url + '/' + path + '?api_key=' + TMDB.api_key
        if method == 'GET':
            headers = {'Accept': 'application/json'}
            content = requests.get(url, params=params, headers=headers).content
        elif method == 'POST':
            for key in params.keys():
                url += '&' + key + '=' + params[key]
            headers = {'Content-Type': 'application/json', \
                       'Accept': 'application/json'}
            content = requests.post(url, data=json.dumps(json_body), \
                                    headers=headers).content
        elif method == 'DELETE':
            for key in params.keys():
                url += '&' + key + '=' + params[key]
            headers = {'Content-Type': 'application/json', \
                       'Accept': 'application/json'}
            content = requests.delete(url, data=json.dumps(json_body), \
                                    headers=headers).content
        else:
            raise Exception('method: ' + method + ' not supported.')
        response = json.loads(content.decode('utf-8'))
        return response

    #
    # Set attributes to dictionary values.
    # - e.g.
    # >>> tmdb = TMDB()
    # >>> movie = tmdb.Movie(103332)
    # >>> response = movie.info()
    # >>> movie.title  # instead of response['title']

    class Movies:
        """ """
        def __init__(self, id=0):
            self.id = id

        # optional parameters: language
        def info(self, params={}):
            path = 'movie' + '/' + str(self.id)
            response = TMDB._request('GET', path, params)
            TMDB._set_attrs_to_values(self, response)
            return response

包装可以在这里找到 我只是想效仿那里的例子

任何帮助都会很好

这可能与方法的缩进有关

\u请求

。请尝试以下代码：

class TMDB:
    def __init__(self, api_key, version=3):
        TMDB.api_key = str(api_key)
        TMDB.url = 'https://api.themoviedb.org' + '/' + str(version)

    def _request(method, path, params={}, json_body={}):
        url = TMDB.url + '/' + path + '?api_key=' + TMDB.api_key

        if method == 'GET':
            headers = {'Accept': 'application/json'}
            content = requests.get(url, params=params, headers=headers).content
        elif method == 'POST':
            for key in params.keys():
                url += '&' + key + '=' + params[key]
            headers = {'Content-Type': 'application/json', \
                'Accept': 'application/json'}
            content = requests.post(url, data=json.dumps(json_body), \
                headers=headers).content
        elif method == 'DELETE':
            for key in params.keys():
                url += '&' + key + '=' + params[key]
            headers = {'Content-Type': 'application/json', \
                'Accept': 'application/json'}
            content = requests.delete(url, data=json.dumps(json_body), \
                headers=headers).content
        else:
            raise Exception('method: ' + method + ' not supported.')
        response = json.loads(content.decode('utf-8'))
        return response

    #
    # Set attributes to dictionary values.
    # - e.g.
    # >>> tmdb = TMDB()
    # >>> movie = tmdb.Movie(103332)
    # >>> response = movie.info()
    # >>> movie.title  # instead of response['title']

    class Movies:
        """ """
        def __init__(self, id=0):
            self.id = id

        # optional parameters: language
        def info(self, params={}):
            path = 'movie' + '/' + str(self.id)
            response = TMDB._request('GET', path, params)
            TMDB._set_attrs_to_values(self, response)
                return response

请参阅，这解释了为什么在使用来自foo import*语法的

时不导入单前导下划线方法。这看起来像一个简单的输入错误。更改：

    def _request(method, path, params={}, json_body={}):

为此：

    def _request(self, method, path, params={}, json_body={}):

正如Github上的@qazwsxpawel所建议的那样，@staticmethod decorators已添加到TMDB类方法请求和设置属性值中。如果您升级了tmdbsimple的版本，那么这些示例现在应该可以在Python2.7中使用了
 我想可能是这样，但没什么区别。我用make_request更改了所有出现的_request，但仍然得到相同的错误。
