Question

以下代码读取文件。

    var filename = process.cwd() + "\\config\\test1.json";
    var fs = require( 'fs' );
    var contents = fs.readFileSync( filename,"utf8" );
        console.log("contents");
    var rulesObject = JSON.parse( contents );

test1.json具有以下内容

textpad

错误

contents
?textpad

undefined:1
∩╗┐textpad
^
SyntaxError: Unexpected token ∩╗┐

Answer 1

  var filename = process.cwd() + "/file.txt";
  var fs = require( 'fs' );
  var contents = fs.readFileSync( filename,"utf8" );
  console.log(contents);

这将读取文件并将其记录下来（将file.txt更改为您的文件）

在Node.js中读取文件时出错会抛出奇怪的字符
