This example transforms a JSON array into a Python array data type via the JSON Decoder. Using its index in a Python object may obtain an element from a JSON array. Example Code: importjson json_str=(""" { "Orders": [ {"Id": 151}, {"Id": 120}, {"Id": 131}, {"Id": 114...

理由: 第一种需要在bean里面加个list,破坏原有的结构。 第二种直接在JSONArray中操作。反正最终传到前端的是json数据,在数据库查出数据后,总要转一次(listtojsonarray) 最后再说一下前端插件 智能推荐 记工作中遇到的两个Python字符串问题 今天工作中写了一个Python脚本,目的是想处理一个数据集合。这个数据集合中...
JSON(JavaScript Object Notation, JS 对象简谱) 是一种轻量级的数据交换格式。易于人阅读和编写。同时也易于机器解析和生成。采用完全独立于语言的文本格式,但是也使用了类似于C语言家族的习惯(包括C, C++, C#, Java, JavaScript, Perl, Python等)。这些特性使JSON成为理想的数据交换语言。
