所以我们通过截取开始索引为8,结束索引为该字符串长度减1,也就是这里的-1,我们就可以获取到第二个值Object,然后再调用toLowerCase()方法来将全部字母转换成小写,然后,我们就可以知道数据的类型了。比如这里的判断是否是数组,那么只需要判断该值是否等于"array"即可。 2.React.createRef API 有时候,我们恰恰需要操作...
argv[1] = client_obj; } wrap_data->MakeCallback(env->onconnection_string(), arraysize(argv), argv); } 过滤掉多余信息便于分析。当新的客户端连接到来时,libuv调用OnConnection,在该函数内执行uv_accept接收连接,最后将js层的回调函数onconnection[通过env->onconnection_string()获取js的回调]和接收到...
