Execute an exe file using node.js
提问by divz
I don't know how to execute an exefile in node.js. Here is the code I am using. It is not working and doesn't print anything. Is there any possible way to execute an exefile using the command line?
我不知道如何exe在node.js. 这是我正在使用的代码。它不工作，不打印任何东西。有没有可能exe使用命令行执行文件的方法？
var fun = function() {
console.log("rrrr");
exec('CALL hai.exe', function(err, data) {
console.log(err)
console.log(data.toString());
});
}
fun();

you can try execFile function of child process modules in node.js
您可以在 node.js 中尝试子进程模块的 execFile 函数
参考：http: //nodejs.org/api/child_process.html#child_process_child_process_execfile_file_args_options_callback
You code should look something like:
您的代码应该类似于：
var exec = require('child_process').execFile;
var fun =function(){
console.log("fun() start");
exec('HelloJithin.exe', function(err, data) {
console.log(err)
console.log(data.toString());
});
}
fun();

If the exethat you want to execute is in some other directory, and your exehas some dependencies to the folder it resides then, try setting the cwdparameter in options
如果exe您要执行的 是在其他目录中，并且您exe对它所在的文件夹有一些依赖性，请尝试cwd在选项中设置参数
var exec = require('child_process').execFile;
/**
* Function to execute exe
* @param {string} fileName The name of the executable file to run.
* @param {string[]} params List of string arguments.
* @param {string} path Current working directory of the child process.
*/
function execute(fileName, params, path) {
let promise = new Promise((resolve, reject) => {
exec(fileName, params, { cwd: path }, (err, data) => {
if (err) reject(err);
else resolve(data);
});
});
return promise;
}
