JSON - MetaTrader 5程序库

这是我在 mql5 中实现的 json 序列化和反序列化功能
您也可以使用 npm 包管理器下载

npm i mql5-json

示例：

 #include "node_modules/mql5-json/index.mqh"

void OnStart () {
    JSON::Object* json1 = new JSON::Object()
        .setProperty( "number" , 123456 )
        .setProperty( "string" , "text" )
        .setProperty( "boolean" , true )
        .setProperty( "object" , new JSON::Object()
            .setProperty( "number" , 123456 )
            .setProperty( "string" , "text" )
            .setProperty( "boolean" , true )
            .setProperty( "array" , new JSON::Array())
        )
        .setProperty( "array" , new JSON::Array()
            .add( true ) // 布尔型
            .add( 123456 ) // 数量
            .add( "string" ) // 字符串
            .add( new JSON::Object()
                .setProperty( "number" , 123456 )
                .setProperty( "string" , "text" )
            )
            .add( new JSON::Array()
                .add( true )
                .add( 123456 )
                .add( "string" )
            )
        );

     string exampleText = json1.toString();
     Print (exampleText);

    JSON::Object* json2 = new JSON::Object(exampleText);
     string objectKeys[];
    json2.getKeysToArray(objectKeys);

     if (
        json2.hasValue( "array" )
        && json2.isArray( "array" )
        && json2.getArray( "array" ).getLength() > 4
        && json2.getArray( "array" ).isBoolean( 0 )
        && json2.getArray( "array" ).getBoolean( 0 ) == true
        && json2.getArray( "array" ).isObject( 3 )
        && json2.getArray( "array" ).getObject( 3 ).isString( "string" )
        && json2.getArray( "array" ).getObject( 3 ).getString( "string" ) == "text"
        && json2.getArray( "array" ).getObject( 3 ).isNumber( "number" )
        && json2.getArray( "array" ).getObject( 3 ).getNumber( "number" ) == double ( 123456 )
    ) {
         Print (json2.toString());
         Print (json2.toString() == json1.toString());
    }

     delete json1;
     delete json2;
}
