这篇文章主要为大家展示了Python如何实现json转字典字符,内容简而易懂,希望大家可以学习一下,学习完之后肯定会有收获的,下面让小编带大家一起来看看吧。
josn基本操作
1.导入import json
2.字典转json:json.dumps(dict,ensure_ascii=False),加,ensure_ascii=False转换之后无中文乱码
3.json转字典:json.loads(str)
4.json转字典:requests.get().josn()
5.返回字符串: requests.get().text
举例源码
#!/usr/bin/python3 # encoding:utf-8 import json import requests class jsonC(): def __init__(self): self.url = 'http://wthrcdn.etouch.cn/weather_mini?city=北京' self.geturl = requests.get(self.url) #字典转json,因为python没json类型所以str表示 def dict_json(self): d = {"name":"张三","age":18} j = json.dumps(d,ensure_ascii=False) print('dict_json函数:类型:',type(d),'转类型',type(j),'\n',j) #json转字典 def json_dict(self): s = '{"name":"张三","age":18}' d = json.loads(s) print('json_dict函数:类型:',type(s),'转类型',type(d)) #接口调用直接返回 字典(dict) def get_json(self): d = self.geturl.json() print('get_json函数类型:',type(d)) #接口调用直接返回字符串 def get_str(self): s = self.geturl.text print('get_str函数返回类型:',type(s)) if __name__=="__main__": js = jsonC() js.dict_json() js.json_dict() js.get_json() js.get_str()
运行结果
dict_json函数:类型: <class 'dict'> 转类型 <class 'str'>
{"name": "张三", "age": 18}
json_dict函数:类型: <class 'str'> 转类型 <class 'dict'>
get_json函数类型: <class 'dict'>
get_str函数返回类型: <class 'str'>
调用get例子
http://wthrcdn.etouch.cn/weather_mini?city=北京
返回json值:
{"data": {"yesterday": {"date":"28日星期六","high":"高温 30℃","fx":"西南风","low":"低温 17℃","fl":"<![CDATA[<3级]]>","type":"晴"}, "city":"北京","forecast": [ {"date":"29日星期天","high":"高温 29℃","fengli":"<![CDATA[<3级]]>","low":"低温 18℃","fengxiang":"南风","type":"晴"}, {"date":"30日星期一","high":"高温 28℃","fengli":"<![CDATA[<3级]]>","low":"低温 19℃","fengxiang":"南风","type":"晴"}, {"date":"1日星期二","high":"高温 29℃","fengli":"<![CDATA[<3级]]>","low":"低温 20℃","fengxiang":"南风","type":"多云"}, {"date":"2日星期三","high":"高温 29℃","fengli":"<![CDATA[<3级]]>","low":"低温 17℃","fengxiang":"南风","type":"晴"}, {"date":"3日星期四","high":"高温 30℃","fengli":"<![CDATA[<3级]]>","low":"低温 12℃","fengxiang":"东南风","type":"多云"} ],"ganmao":"各项气象条件适宜,无明显降温过程,发生感冒机率较低。","wendu":"29" },"status":1000,"desc":"OK" }
