我的json文件看起来像这样,我正在尝试访问syslogfor循环中的元素.

{
  "cleanup":{
    "folderpath":"/home/FBML7HR/logs",
    "logfilename":""
  },
  "preparation":{
    "configuration":{
      "src_configfile":"src.cfg",
      "dest_configfile":"/var/home/FBML7HR/etc/vxn.cfg"
    },
    "executable_info1":[
      {
        "login_info":{
          "hostname":"10.4.0.xxx",
          "username":"***",
          "password":"***"
        }
      },
      {
        "command":{
          "folderpath":"/var/home/FBML7HR/SrcCode/vxnservers/fdchost/north/test/hostsim/",
          "processname":"northhostsim",
          "parameters":"-d"
        }
      }
    ],
    "executable_info2":[
      {
        "login_info":{
          "hostname":"10.4.0.xxx",
          "username":"***",
          "password":"***"
        }
      },
      {
        "command":{
          "folderpath":"/var/home/FBML7HR/SrcCode/vxnservers/fdchost/north/build/Linux-2.6.18-194.8.1.el5/bin",
          "processname":"northhost",
          "parameters":"-s brazil -d"
        }
      }
    ],
    "executable_info3":[
      {
        "login_info":{
          "hostname":"10.4.0.xxx",
          "username":"***",
          "password":"***"
        }
      },
      {
        "command":{
          "folderpath":"cd /var/home/xxx/SrcCode/vxnservers/fdchost/north/test/vxnclient_mt",
          "processname":"vxnclient_north_mt",
          "parameters":"0 320 205 14897 16880 60000 60000 2 2"
        }
      }
    ]
  },
  "execution":[
    {
      "test_case":{
        "scriptname":"/var/home/FBML7HR/test/testcase1.sh",
        "testreport":{
          "syslog":"/var/log/messages",
          "backupsyslog":"backuplogs1.txt", …

我正在尝试开发一个使用 json 来描述数据的测试自动化框架。我有一个 json 文件，如下所示：

{
  "preparation":{
    "configuration":[
      {
        "config1":{
          "src_configfile":"/home/xxx/etc/src_config1.cfg",
          "dest_configfile":"/home/xxx/etc/abc.cfg"
        }
      },
      {
        "config2":{
          "src_configfile":"/home/xxx/etc/src_config2.cfg",
          "dest_configfile":"/home/xxx/etc/xyz.cfg"
        }
      }
    ],
    "executable_info1":[
      {
        "login_info":{
          "hostname":"abc.dw",
          "username":"xyz",
          "password":"*******"
        }
      },
      {
        "command":{
          "folderpath":"/home/xxx/yyy/bin",
          "processname":"sys.exe",
          "parameters":"-d"
        }
      }
    ],
  },
  "execution":[
    {
      "test_case1":{
        "folderpath":"/home/xxx/testscripts",
        "scriptname":"test_case1.py",
       ***???????????Can I access the config1 object here???????????? 
       "config_file"="preparation.configuration[0].config1.dest_configfile"***
      }
    },
    {
      "test_case1":{
        "folderpath":"/home/xxx/testscripts",
        "scriptname":"test_case2.py",
        ***"config_file"="preparation.configuration[1].config2.dest_configfile"***
      }
    }
  ]
}

我需要对不同的测试用例使用不同的配置文件。我可以在执行中引用准备对象的config1对象吗？？？

当我运行此代码时:

int arr[3] = {2,3,4};
char *p;
p = (char*)arr;
printf("%d", *p);
p = p+1;
printf("%d", *p);

输出为2和0.第二个结果有点令人困惑.有人可以解释为什么会这样吗？
