[英]Axios call from Node API to PHP server leads to socket hangup
我使用 Express 在 Nodejs 中创建了一个 API。
在调用 Node API 时,它会读取一个文件并将其发送到部署在 Apache 中的 PHP 服务器。从 PHP 服务器接收响应并将其发送回我的 Node API 的调用者。 第一次命中我的节点 API 时,它返回正确的结果。从第二次命中开始,“套接字挂断”是我得到的错误。
var express = require('express')
var app = express()
const axios = require('axios');
var path = require('path');
const FormData = require('form-data');
const form = new FormData();
var fs = require('fs');
var dir = './tmp';
app.get('/file', function(request, responses) {
new Promise((resolve , reject)=>{
form.append('file',fs.createReadStream(dir+'/FileCreated.txt'));
resolve(form);
}).then(form => {
console.log('Sending file to the PHP ');
let url = 'http://121.115.158.12/upload.php';
axios({
method: 'post',
url: url,
// timeout : 3000,
data: form,
headers: {
'content-type': `multipart/form-data;boundary=${form._boundary} `,//
}
})
.then(function (response) {
console.log(response.status);
responses.send({status:response.status , data: response.data});
responses.end();
})
.catch(function (error) {
console.log(error);
responses.send({status:error.status , data: error.Error});
responses.end();
});
request.on('end', function() {
console.log('close');
});
})
})
我从第二个 Axios 收到的错误开始出现。

观察:
1)第一次命中 PHP 服务器(部署在 Apache 中)已正确记录在 Apache 的日志文件中,但从第二次命中开始,Apache 中没有日志可能告诉我 Axios 请求甚至没有到达 Apache?
2)我又构建了一个 Node API 只是为了检查我是否点击了该 API,然后我会收到套接字挂断错误,但是这个 API每次都运行。即使我在上述 API 上遇到套接字挂断,这个 API 也能完美运行。
app.get('/random', function(request, responses) {
console.log(responses);
responses.send('Just to check');
})
仍然无法找到问题的原因。 我找到了一个回旋处,并使用Shell脚本使用Shell.js命中PHP服务器。
此解决方案效果很好。
我面临同样的问题......我有相同的过程来发送数据。 节点服务器使用 axios 获取和发送(发布)数据到托管在 apache 服务器中的 php 服务器。
请给我建议代码示例
我正在使用它来发布数据
const newInstance = axios.create({ url: http://in.truemagic-media.com/import_data/${channelId}
, method: 'post', headers: { "USERKEY": "TYapJkTR", "PASSWORD": "z85qTWnA" }, timeout: 1800000, httpAgent: new http.Agent({ keepAlive: true }) });
let result = await newInstance.post(`http://in.truemagic-media.com/import_data/${channelId}`,dataTOSend)
return result;
