我试图格式化一个json数组并将其发送到服务器。我已经尝试了下面的代码,并得到正确的字符串输出。Json数组中的json对象的格式与for循环在C
json_t* json_arr = json_array();
json_t* json_request = json_object();
json_t* json_request1 = json_object();
json_t* host = json_object();
json_t* host1 = json_object();
char *buf;
json_object_set_new(json_request, "mac", json_string("005056BD3B6C"));
json_object_set_new(host, "os_type", json_string("Linux_Fedora"));
json_object_set_new(host, "user_agent", json_string("Wget/1.10.2 (Fedora modified)"));
json_object_set_new(json_request1, "mac", json_string("005056BD3B60"));
json_object_set_new(host1, "os_type", json_string("Linux_Fedora"));
json_object_set_new(host1, "user_agent", json_string("Wget/1.10.2 (Fedora modified)"));
json_object_set_new(json_request ,"host", host);
json_object_set_new(json_request1 ,"host", host1);
json_array_append(json_arr ,json_request);
json_array_append(json_arr ,json_request1);
buf = json_dumps(json_arr ,JSON_PRESERVE_ORDER);
输出:
[
{
"mac":"005056BD3B6C",
"host":{
"os_type":"Linux_Fedora",
"user_agent":"Wget/1.10.2 (Fedora modified)"
}
},
{
"mac":"005056BD3B60",
"host":{
"os_type":"Linux_Fedora",
"user_agent":"Wget/1.10.2 (Fedora modified)"
}
}
]
我希望把中环上面的代码按我requirement.so我尝试下面的代码。
json_t* json_arr = json_array();
char *buf;
const char *str[3];
str[0] = "005056b4800c";
str[1] = "005056b4801c";
str[2] = "005056b4802c";
for (i=0;i<3;i++)
{
json_t* json_request = json_object();
json_t* host = json_object();
json_object_set_new(json_request, "mac", json_string(str[i]));
json_object_set_new(host, "os_type", json_string("Linux_Fedora"));
json_object_set_new(host, "user_agent", json_string("Wget/1.10.2 (Fedora modified)"));
json_object_set_new(json_request ,"host", host);
json_array_append(json_arr ,json_request);
json_decref(json_request);
json_decref(host);
}
buf = json_dumps(json_arr ,JSON_PRESERVE_ORDER);
这里我得到了下面的缓冲值:
[
{
"mac":"005056b4800c",
"host":{
"mac":"005056b4801c",
"host":{
"mac":"005056b4802c",
"host":{
}
}
}
},
{
"mac":"005056b4801c",
"host":{
"mac":"005056b4802c",
"host":{
}
}
},
{
"mac":"005056b4802c",
"host":{
}
}
]
如何使用环和如上述相同的格式化阵列?
也许你想告诉我们你正在使用哪个JSON库。是Jansson吗? – Gerhardh
