我无法从npm安装任何节点模块.

npm install socket.io

上面的命令产生了以下输出,它无法安装socket.io

npm http GET https://registry.npmjs.org/socket.io

app.post('/asset', function(request, response){
  var tempFile="/home/applmgr/Desktop/123456.pdf";
  fs.readFile(tempFile, function (err,data){
     response.contentType("application/pdf");
     response.send(data);
  });
});

我是表达js的新bie,我不能用数据对象发送响应.二进制内容在浏览器中可见.给我建议如何处理这个？

以下是三个文件的示例代码:

// foo.js
var myFunc = require("./myFunc");
function foo(){
   myFunc("message");
}

// bar.js
var myFunc = require("./myFunc");
function bar(){
   myFunc("message");
}

// myFunc.js
module.exports = myFunc;
function myFunc(arg1){
   console.log(arg1);
   // Here I need the file path of the caller function
   // For example, "/path/to/foo.js" and "/path/to/bar.js"
}

我需要动态获取调用函数的文件路径,而不需要传递任何额外的参数myFunc.

我想知道我的NodeJS支持哪个javascript版本？

对于任何级别的每个logger语句,我需要显示执行日志语句的文件名,下面是我在下面给出的插图:

示例:下面是从JobWork.js执行的行

logger.info("getInCompleteJobs in job works");

实际:

2012-11-05T06:07:19.158Z - info: getInCompleteJobs in job works

要求:

2012-11-05T06:07:19.158Z - info JobWork.js : getInCompleteJobs in job works

如果不将fileName作为日志语句中的参数传递,则应该给出文件名.

是否可以将多个表格的数据存储到单个QVD文档中？

如果是这样,我如何在这个QVD中存储和加载多个表？
