[cocos]异常捕获

__errorHandler函数

cocos在js-binding会调用全局的__errorHandler函数, 传入发生异常的文件路径, 行数, 错误信息以及调用栈, 类似window.onerror = function(message, source, lineno, colno, error) { ... }

            if (!_isErrorHandleWorking)
            {
                _isErrorHandleWorking = true;

                Value errorHandler;
                if (_globalObj->getProperty("__errorHandler", &errorHandler) && errorHandler.isObject() && errorHandler.toObject()->isFunction())
                {
                    ValueArray args;
                    args.push_back(Value(filePath));
                    args.push_back(Value(report->lineno));
                    args.push_back(Value(message));
                    args.push_back(Value(stack));
                    errorHandler.toObject()->call(args, _globalObj);
                }

                _isErrorHandleWorking = false;
            }
            else
            {
                SE_LOGE("ERROR: __errorHandler has exception\n");
            }

一个异常数据

模拟一个异常

	apmTest() {
		console.log('apmTest')
		const a: any = {}
		a.b.g = 0
	}

收集到的异常数据
