Node.js：JSONデータをPOSTする

※「≈≈≈」は省略を表す

バージョン

$ node -v
v6.2.1

$ cat package.json
{
  ≈≈≈
  "dependencies": {
    "request": "~2.72.0",
  }
}

POSTでJSONデータを送信する

var request = require('request');
var options = {
  uri: "http://example.com/test",
  headers: {
    "Content-type": "application/json",
  },
  json: {
    "key1": "param1",
    "key2": "param2"
  }
};
request.post(options, function(error, response, body){});

おまけ：POSTでパラメータを送信する(いわゆるフツーのPOST)(未検証)

var request = require('request');
var options = {
  uri: "http://example.com/test",
  headers: {
    "Content-type": "application/x-www-form-urlencoded",
  },
  form: {
    "key1": "param1",
    "key2": "param2"
  }
};
request.post(options, function(error, response, body){});
