python中的JSON到dict不存在

Question

我有一个函数在一个类中调用json，它将返回一个json字符串，如下所示：

{'clusters':[{ 'host':'hostj', 'name':'s3', 'port':'poorke', 'profile':'profil', 'region':'regieo', 'user':'userk' }]}

现在我想从中创建一个dict。当我使用以下代码时：

new_cluser_dict = json.loads(clusterx.to_JSON())

我得到以下错误：

Traceback (most recent call last):

您需要将单引号替换为双引号：

clusterx.to_JSON().replace("'", '"')
