以下 curl 命令完美地调用、传递参数和执行我的“jobified”火花程序

curl 'http://someserver:8090/jobs?appName=secondtest&classPath=Works.epJob&context=hiveContext' -d "inputparms=/somepath1 /somepath2"

这是火花程序

override def runJob(hive: HiveContext, config: Config):Any = {  
var inputParms = config.getString("inputparms").split(" "); //comes from node
var path1 = inputParms.apply(0)
var path2 = inputParms.apply(1)

我需要在 node.js 中做一个 http 帖子，而不是 curl 命令。这是我所拥有的

var postData = JSON.stringify({
  "inputparms": paths
})

var options = {
hostname: 'someserver',
port: 8090,
path: '/jobs?appName=secondtest&classPath=Works.epJob context=hiveContext',
method: 'POST',
headers: {
    'Content-Type': 'application/json',
    'Content-Length': Buffer.byteLength(postData , 'utf8')
}
};

 http.request(options, function(response) {...

但是，上面的脚本不起作用。我错过了什么吗？谢谢！

编辑1：

 var myreq = http.request(options, function(response) { ...})
 myreq.write(postData);
 myreq.end();

我得到一个解析错误

以下对我有用

var http = require("http");
var options = {
  hostname: 'localhost',
  port: 8090,
  path: '/jobs?appName=test&classPath=spark.jobserver.LongPiJob',
  method: 'POST',
  headers: {
      'Content-Type': 'application/json',
  }
};
var req = http.request(options, function(res) {
  console.log('Status: ' + res.statusCode);
  console.log('Headers: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (body) {
    console.log('Body: ' + body);
  });
});
req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});
// write data to request body
req.write('stress.test.longpijob.duration=120');
req.end();
