环境：windows7+xampp
需要实现：php curl模拟form表单上传多个文件，后端nodejs（express+multer）接收请求+保存文件
出现情况：单文件上传可行，多文件报错
版本：php 5.6+nodejs 6.11.4
function curl_upload($url, $timeout = 1000) {
$ch = curl_init();
$data = array(
'upload' => curl_file_create('E:\www\vhost.php', 'text/html', 'ph')
);
//兼容5.0-5.6版本的curl
if (class_exists('\CURLFile')) {
} else {
if (defined('CURLOPT_SAFE_UPLOAD')) {
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, FALSE);
}
}
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_exec($ch);
var fs = require('fs')
var express = require('express')
var multer = require('multer')
const path = require('path');
var app = express();
var upload = multer({
dest: 'upload/'
});
//多文件上传 （限定上传文件个数）（没有修改后缀）
app.post('/upload-multi', upload.array('upload', 3), function(req, res, next) {
var file = req;
console.log(file);
})变成多文件后：
function curl_upload($url, $timeout = 1000) {
$ch = curl_init();
$data = array(
'upload[0]' => curl_file_create('E:\www\vhost.php', 'text/html', 'ph'),
'upload[1]' => curl_file_create('E:\www\ser.php', 'text/html', 'ser')
);
//兼容5.0-5.6版本的curl
if (class_exists('\CURLFile')) {
} else {
if (defined('CURLOPT_SAFE_UPLOAD')) {
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, FALSE);
}
}
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_exec($ch);
}如下：使用正常的表单上传多文件，nodejs能正常接收
