我如何能使出站HTTP POST请求,与数据,在node.js?
当前回答
var https = require('https');
/**
* HOW TO Make an HTTP Call - POST

// do a POST request
// create the JSON object
jsonObject = JSON.stringify({
"message" : "The web of things is approaching, let do some tests to be ready!",
"name" : "Test message posted with node.js",
"caption" : "Some tests with node.js",
"link" : "http://www.youscada.com",
"description" : "this is a description",
"picture" : "http://youscada.com/wp-content/uploads/2012/05/logo2.png",
"actions" : [ {
"name" : "youSCADA",
"link" : "http://www.youscada.com"
} ]
});
// prepare the header
var postheaders = {
'Content-Type' : 'application/json',
'Content-Length' : Buffer.byteLength(jsonObject, 'utf8')
};
// the post options
var optionspost = {
host : 'graph.facebook.com',
port : 443,
path : '/youscada/feed?access_token=your_api_key',
method : 'POST',
headers : postheaders
};
console.info('Options prepared:');
console.info(optionspost);
console.info('Do the POST call');
// do the POST call
var reqPost = https.request(optionspost, function(res) {
console.log("statusCode: ", res.statusCode);
// uncomment it for header details
// console.log("headers: ", res.headers);
res.on('data', function(d) {
console.info('POST result:\n');
process.stdout.write(d);
console.info('\n\nPOST completed');
});
});
// write the json data
reqPost.write(jsonObject);
reqPost.end();
reqPost.on('error', function(e) {
console.error(e);
});

通过使用请求依赖性。
简单的解决方法:
import request from 'request'
var data = {
"host":"127.1.1.1",
"port":9008
}
request.post( baseUrl + '/peers/connect',
{
json: data, // your payload data placed here
headers: {
'X-Api-Key': 'dajzmj6gfuzmbfnhamsbuxivc', // if authentication needed
'Content-Type': 'application/json'
}
}, function (error, response, body) {
if (error) {
callback(error, null)
} else {
callback(error, response.body)
}
});
let request = require('request');
let jsonObj = {};
request({
url: "https://myapii.com/sendJsonData",
method: "POST",
json: true,
body: jsonObj
}, function (error, resp, body){
console.log(resp);
});
或者你可以使用这个库:
let axios = require("axios");
let jsonObj = {};
const myJsonAPI = axios.create({
baseURL: 'https://myapii.com',
timeout: 120*1000
});
let response = await myJsonAPI.post("sendJsonData",jsonobj).catch(e=>{
res.json(e);
});
console.log(response);
您可以使用请求库。https://www.npmjs.com/package/request
var request = require('request');
要发布JSON数据:
var myJSONObject = { ... };
request({
url: "http://josiahchoi.com/myjson",
method: "POST",
json: true, // <--Very important!!!
body: myJSONObject
}, function (error, response, body){
console.log(response);
});
要发布xml数据:
var myXMLText = '<xml>...........</xml>'
request({
url: "http://josiahchoi.com/myjson",
method: "POST",
headers: {
"content-type": "application/xml", // <--Very important!!!
},
body: myXMLText
}, function (error, response, body){
console.log(response);
});
编辑:截至2020年2月,请求已弃用。
这是我用来发出请求的最简单的方式:使用'request'模块。
命令安装'request'模块:
$ npm install request
示例代码:
var request = require('request')
var options = {
method: 'post',
body: postData, // Javascript object
json: true, // Use,If you are sending JSON data
url: url,
headers: {
// Specify headers, If any
}
}
request(options, function (err, res, body) {
if (err) {
console.log('Error :', err)
return
}
console.log(' Body :', body)
});
你也可以使用Node.js内置的“http”模块来发出请求。
