Question

我的函数返回一个我赋给变量的字符串值。我将它转换为json，我想返回＆＃39; printer_id＆＃39;

的值

代码：

import json
def getprinterid():
    s='''
    {
    "printer_config": {
    "printer_id": "AQAAAAFhvL8CXQ",
    "conn_config_url": "https://connectivity",
    "printer_caps_url": "https://deviceconfig",
    "cred_refresh_url": "https://registration"
    }
    ,"cloud_config": {
    "eprint_enabled": true,
    "sips_enabled": true,
    "mobile_print_enabled": true
    }
    }
    '''

    decodedinfo = json.loads(s)
    for x in decodedinfo:
        if x == "printer_config":
            for y in decodedinfo[x]:
                if y == "printer_id":
                    return decodedinfo[x][y]

解码后的json将是一个字典，你可以直接引用它的键：

import json

def getprinterid():
    s = '''
    { 
    "printer_config": {
    "printer_id": "AQAAAAFhvL8CXQ",
    "conn_config_url": "https://connectivity",
    "printer_caps_url": "https://deviceconfig",
    "cred_refresh_url": "https://registration"
    } 
    ,"cloud_config": {
    "eprint_enabled": true,
    "sips_enabled": true,
    "mobile_print_enabled": true
    } 
    } 
    '''

    decoded = json.loads(s)
    return decoded['printer_config']['printer_id']
