josn基本操作

1.导入importjson

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
importjson
importrequests

classjsonC():
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
defdict_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
defjson_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）
defget_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
defget_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：转类型
{"name":"张三","age":18}
json_dict函数：类型：转类型
get_json函数类型：
get_str函数返回类型：

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":"","type":"晴"},
		"city":"北京","forecast":
		[
			{"date":"29日星期天","high":"高温29℃","fengli":"","low":"低温18℃","fengxiang":"南风","type":"晴"},
			{"date":"30日星期一","high":"高温28℃","fengli":"","low":"低温19℃","fengxiang":"南风","type":"晴"},
			{"date":"1日星期二","high":"高温29℃","fengli":"","low":"低温20℃","fengxiang":"南风","type":"多云"},
			{"date":"2日星期三","high":"高温29℃","fengli":"","low":"低温17℃","fengxiang":"南风","type":"晴"},
			{"date":"3日星期四","high":"高温30℃","fengli":"","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"
}
