测试数据：

# 数组
data = [{
    "key": "1.0.1",
    "token": "zlsj",
    "appid": 20386
}, {
    "key": "1.0.2",
    "token": "zlj",
    "appid": 20321
}]

输出结果：

Key: 0
Value: "{\"key\":\"1.0.1\",\"token\":\"zlsj\",\"appid\":20386}"
--------------------------------------------------
Key: 1
Value: "{\"key\":\"1.0.2\",\"token\":\"zlj\",\"appid\":20321}"
--------------------------------------------------
[{\"key\":\"1.0.1\",\"token\":\"zlsj\",\"appid\":20386},{\"key\":\"1.0.2\",\"token\":\"zlj\",\"appid\":20321}]
