c - JSON - 对象的嵌套

Question

如何在 C 编程中将 [ 和 ] 附加到 json 对象......

我有类似的东西

      json_builder_begin_object(builder);
      json_builder_set_member_name( builder, "response" );
      json_builder_add_string_value( builder, "success" );

      json_builder_set_member_name( builder, "data" );
      json_builder_begin_object( builder );
      json_builder_set_member_name( builder, "type" );
      json_builder_add_string_value( builder, "vehicle " );
       json_builder_set_member_name( builder, "value" );
       json_builder_add_string_value( builder, ">10lakhs " );
        json_builder_set_member_name(builder,"color");
        json_builder_add_string_value(builder,"Black");

我需要这样的回复

[{"response":"成功"},"data"[{"type":"vehicle"},{"value":">100万美元"},{"color":"black"}]]

您必须使用 set_member_name 和 begin_object。前者设置子对象的名称，后者初始化子对象，以便其余数据进入其中。

例如，来 self 的Countly app :

  json_builder_begin_object (builder);

  if(crash->hardware){
      json_builder_set_member_name (builder, "hardware");
      json_builder_begin_object(builder);
      if(crash->hardware->os){
      json_builder_set_member_name (builder, "_os");
      json_builder_add_string_value (builder, crash->hardware->os);
      }

      if(crash->hardware->os_version) {
      json_builder_set_member_name (builder, "_os_version");
      json_builder_add_string_value (builder, crash->hardware->os_version);
      }
      if(crash->hardware->manufacture) {
      json_builder_set_member_name (builder, "_manufacture");
      json_builder_add_string_value (builder, crash->hardware->manufacture);
      }
      if(crash->hardware->device) {
      json_builder_set_member_name (builder, "_device");
      json_builder_add_string_value (builder, crash->hardware->device);
      }
      if(crash->hardware->resolution) {
      json_builder_set_member_name (builder, "_resolution");
      json_builder_add_string_value (builder, crash->hardware->resolution);
      }
      if(crash->hardware->app_version) {
      json_builder_set_member_name (builder, "_app_version");
      json_builder_add_string_value (builder, crash->hardware->app_version);
      }
      if(crash->hardware->cpu) {
      json_builder_set_member_name (builder, "_cpu");
      json_builder_add_string_value (builder, crash->hardware->cpu);
      }
      if(crash->hardware->opengl) {
      json_builder_set_member_name (builder, "_opengl");
      json_builder_add_string_value (builder, crash->hardware->opengl);
      }
      json_builder_end_object (builder);

  }
