c语言JSON库 Parson的编译和使用

最近一直学习ndk，Android肯定会用到json，这里介绍一个c语言写成的JSON解析库

Parson介绍

Parson is a lighweight json library written in C.

c语言中使用的一个轻量级的json库

特点：

• Full JSON support
• Lightweight (only 2 files)
• Simple API
• Addressing json values with dot notation (similar to C structs or objects in most OO languages, e.g. “objectA.objectB.value”)
• C89 compatible
• Test suites

简单使用

1. 构造json

   void serialization_example(void) {
       JSON_Value *root_value = json_value_init_object();
       JSON_Object *root_object = json_value_get_object(root_value);
       
       char *serialized_string = NULL;
       json_object_set_string(root_object, "name", "John Smith");
       json_object_set_number(root_object, "age", 25);
       json_object_dotset_string(root_object, "address.city", "Cupertino");
       json_object_dotset_value(root_object, "contact.emails", json_parse_string("[\"[e-mail]\",\"[e-mail]\"]"));
       
       serialized_string = json_serialize_to_string_pretty(root_value);
       puts(serialized_string);
       
       json_free_serialized_string(serialized_string);
       json_value_free(root_value);
   }
   

   输出内容：

   {
       "name": "John Smith",
       "age": 25,
       "address": {
           "city": "Cupertino"
       },
       "contact": {
           "emails": [
               "[e-mail]",
               "[e-mail]"
           ]
       }
   }
