然后,我们创建了一个名为blobToBase64的异步函数,该函数接受一个Blob文件路径作为参数。 在blobToBase64函数中,我们使用readFile函数以二进制模式读取Blob文件。接着,我们使用Buffer.from()方法将二进制数据转换为Base64编码的字符串。 最后,我们使用一个自执行的异步函数来调用blobToBase64函数,并打印转换后的B...

原生模块即Node.jsAPI提供的原声模块,原生模块在启动时已经被加载。(如:os模块、http模块、fs模块、buffer模块、path模块等) //调用原生模块不需要指定路径 var http = require('http'); 文件模块为动态加载模块,加载文件模块的主要由原生模块module来实现和完成。原生模块在启动时已经被加载,而文件模块则需要通过调...
