我如何能使出站HTTP POST请求,与数据,在node.js?
当前回答
发布另一个axios的例子。Post请求,使用额外的配置选项和自定义头。
var postData = { 电子邮件:“test@test.com”, 密码:“密码” }; let axiosConfig = { 标题:{ “内容类型”:“application / json; charset = utf - 8”, “Access-Control-Allow-Origin”:“*”, } }; axios。post('http://<主机>:<端口>/<路径>',postData, axiosConfig) .then((res) => { console.log("RESPONSE RECEIVED: ", res); }) .catch((err) => { console.log("AXIOS ERROR: ", err); })

请求现在已弃用。建议您使用替代方案
无特定顺序且极不完整的:
const https = require('https'); node-fetch axios 得到了 搞 弯曲 make-fetch-happen unfetch tiny-json-http 针 urllib
统计比较 一些代码示例
最初的回答:
如果使用请求库,这将变得容易得多。
var request = require('request');
request.post(
'http://www.yoursite.com/formpage',
{ json: { key: 'value' } },
function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
}
);
除了提供一个不错的语法,它使json请求更容易,处理oauth签名(twitter等),可以做多部分的表单(例如上传文件)和流。
安装请求使用npm install request命令
在Node.js 18
跟节点获取包、axios和request说再见吧……现在默认情况下,全局作用域中的获取API是可用的。
const res = await fetch('https://nodejs.org/api/documentation.json');
if (res.ok) {
const data = await res.json();
console.log(data);
}
我们可以像在浏览器中那样发出请求。

在为我的项目创建了一个低级实用程序来处理帖子和获取请求之后,我决定在这里发布我的努力。这里有一个关于发送JSON数据的http和https POST请求的代码片段。
const http = require("http")
const https = require("https")
// Request handler function
let postJSON = (options, postData, callback) => {
// Serializing JSON
post_data = JSON.stringify(postData)
let port = options.port == 443 ? https : http
// Callback function for the request
let req = port.request(options, (res) => {
let output = ''
res.setEncoding('utf8')
// Listener to receive data
res.on('data', (chunk) => {
output += chunk
});
// Listener for intializing callback after receiving complete response
res.on('end', () => {
let obj = JSON.parse(output)
callback(res.statusCode, obj)
});
});
// Handle any errors occurred while making request
req.on('error', (err) => {
//res.send('error: ' + err.message)
});
// Request is made here, with data as string or buffer
req.write(post_data)
// Ending the request
req.end()
};
let callPost = () => {
let data = {
'name': 'Jon',
'message': 'hello, world'
}
let options = {
host: 'domain.name', // Your domain name
port: 443, // 443 for https and 80 for http
path: '/path/to/resource', // Path for the request
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': Buffer.byteLength(data)
}
}
postJSON(options, data, (statusCode, result) => {
// Handle response
// Process the received data
});
}
下面是一个使用node.js向谷歌编译器API发出POST请求的例子:
// We need this to build our post string
var querystring = require('querystring');
var http = require('http');
var fs = require('fs');
function PostCode(codestring) {
// Build the post string from an object
var post_data = querystring.stringify({
'compilation_level' : 'ADVANCED_OPTIMIZATIONS',
'output_format': 'json',
'output_info': 'compiled_code',
'warning_level' : 'QUIET',
'js_code' : codestring
});
// An object of options to indicate where to post to
var post_options = {
host: 'closure-compiler.appspot.com',
port: '80',
path: '/compile',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': Buffer.byteLength(post_data)
}
};
// Set up the request
var post_req = http.request(post_options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('Response: ' + chunk);
});
});
// post the data
post_req.write(post_data);
post_req.end();
}
// This is an async file read
fs.readFile('LinkedList.js', 'utf-8', function (err, data) {
if (err) {
// If this were just a small part of the application, you would
// want to handle this differently, maybe throwing an exception
// for the caller to handle. Since the file is absolutely essential
// to the program's functionality, we're going to exit with a fatal
// error instead.
console.log("FATAL An error occurred trying to read in the file: " + err);
process.exit(-2);
}
// Make sure there's data before we post it
if(data) {
PostCode(data);
}
else {
console.log("No data to post");
process.exit(-1);
}
});
我已经更新了代码,以展示如何从文件中发布数据,而不是硬编码的字符串。它使用异步文件系统。readFile命令来实现这一点,在成功读取后发布实际代码。如果出现错误,则抛出错误,如果没有数据,则进程退出,并显示一个负值以指示失败。
var https = require('https');
/**

console.info('Do the POST call');
// do the POST call
var reqPost = https.request(optionspost, function(res) {
console.log("statusCode: ", res.statusCode);

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);
});
