一、先来看下json格式的数据如何取出某个字段,列如:我要取出里面的 lcate和guid,输出的样式要是:

1;904eff52277f403b89f6410fe2758646.11

2;58457f60eca64025bc43a978f9c98345.16

3;a0f907f9dc8b40f689b083f3eba7228b.16

4;eb75d929455e468bb712e7bc2025d11a.16



json_data = """{
   "favourite":{
      "bkmrk":{
         "id1490843709594066":{
            "guid":"904eff52277f403b89f6410fe2758646.11",
            "lcate":"1"
         },
         "id1490843712805183":{
            "guid":"58457f60eca64025bc43a978f9c98345.16",
            "lcate":"2"
         },
         "id149084371467327":{
            "guid":"a0f907f9dc8b40f689b083f3eba7228b.16",
            "lcate":"3"
         },
         "id1490843716295393":{
            "guid":"eb75d929455e468bb712e7bc2025d11a.16",
            "lcate":"4"
         }
      }
   }
}"""

那么我们写的代码很简单:

如下:

import json

json_data = """{
   "favourite":{
      "bkmrk":{
         "id1490843709594066":{
            "guid":"904eff52277f403b89f6410fe2758646.11",
            "lcate":"1"
         },
         "id1490843712805183":{
            "guid":"58457f60eca64025bc43a978f9c98345.16",
            "lcate":"2"
         },
         "id149084371467327":{
            "guid":"a0f907f9dc8b40f689b083f3eba7228b.16",
            "lcate":"3"
         },
         "id1490843716295393":{
            "guid":"eb75d929455e468bb712e7bc2025d11a.16",
            "lcate":"4"
         }
      }
   }
}"""

data = json.loads(json_data)
for v in data['favourite']['bkmrk'].values():
    print("%s;%s" % (v['lcate'],  v['guid']))

 

二、下面再来说一下,如何把dict格式写成json格式的文件夹中:

import json


def write_to_json(ips):
    with open('proxies.json', 'w', encoding='utf-8') as f:
        json.dump(ips, f, indent=4)


ips = [{'ip':'12.234.232.43', 'port':8978, 'type':'https'},{'ip':'45.234.232.43', 'port':2378, 'type':'https'},{'ip':'17.883.232.43', 'port':978, 'type':'https'}]


write_to_json(ips)
