可读流中的txt.properties属性用于获取声明的可读流的属性编码。此外,您可以使用可读.setEncoding()方法设置此属性。
用法:
readable.readableEncoding
返回值:它返回程序中使用的编码。
以下示例说明了Node.js中visible.sensitiveEncoding属性的使用:
范例1:
// Node.js program to demonstrate the
// readable.readableEncoding Property
// Include fs module
const fs = require("fs");
// Constructing readable stream
const readable = fs.createReadStream("input.text");
// Setting the encoding
readable.setEncoding("base64");
// Instructions for reading data
readable.on('readable', () => {
let chunk;
// Using while loop and calling
// read method with parameter
while (null !== (chunk = readable.read())) {
// Displaying the chunk
console.log(`read:${chunk}`);
}
});
// Calling readableEncoding property
readable.readableEncoding;
输出:
read:aGVs read:bG8=
范例2:
// Node.js program to demonstrate the
// readable.readableEncoding Property
// Include fs module
const fs = require("fs");
// Constructing readable stream
const readable = fs.createReadStream("input.text");
// Setting the encoding
readable.setEncoding("hex");
// Instructions for reading data
readable.on('readable', () => {
let chunk;
// Using while loop and calling
// read method with parameter
while (null !== (chunk = readable.read())) {
// Displaying the chunk
console.log(`read:${chunk}`);
}
});
// Calling readableEncoding property
readable.readableEncoding;
输出:
read:68656c6c6f
