Laravel6 alioss上传csv 并读取远程csv文件

3.在 composer.json
中 autoload -> classmap
处增加配置(composer.json在lavarel项目的根目录下
):
"autoload": {
"classmap": [
"app/services"
]
}
4.运行命令(注意切换到项目根目录):
composer dump-autoload
5.应用(比如在控制器里边应用):
<?php
namespace App\Http\Controllers;
/*....省略其他命名空间的引用*/
use App\Services\OSS;
class TestController extends Controller
{
public function __construct()
{
parent::__construct();
}
/**
*
* csv 读取
*/
public function opt(Request $request){
ini_set('memory_limit','1024M'); // 临时设置最大内存占用为3G
set_time_limit(0); // 设置脚本最大执行时间 为0 永不过期
$ex = $_FILES['file'];
if ($ex['error']) {
return back()->with('error', '未提交文件。请选择要导入的文件,然后重试');
}
try {
$bucket = "bucket_name";
$filename = time() . substr($ex['name'], stripos($ex['name'], '.'));
$alios = OSS::publicUpload($bucket, $filename, $ex['tmp_name']);
if(!$alios){
//错误处理
exit("err1");
}
$path = OSS::getPublicObjectURL($bucket,$filename);
if(!$path){
//错误处理
exit("err2");
}
$data = $this->read_csv($path);
print_r($data);
}
/**
*读取csv内容
*代码来源地址:https://www.jb51.net/article/104814.htm
*
*/
function read_csv($cvs) {
$shuang = false;
$str = file_get_contents($cvs);
$str = iconv('gbk', 'utf-8', $str);
for ($i=0;$i<strlen($str);$i++) {
if($str{$i}=='"') {
if($shuang) {
if($str{$i+1}=='"') {
$str{$i} = '*';
$str{$i+1} = '*';
} else {
$shuang = false;
}
} else {
$shuang = true;
}
}
if($str{$i}==',') {
if($shuang) {
} else {
$str{$i} = '|';
}
}
if($str{$i}=="\n") {
if($shuang) {
$str{$i} = '^';
} else {
}
}
}
$str = str_replace(array('"','*'),array('','"'),$str);
$a1 = explode("\n",$str);
$array = array();
foreach($a1 as $k=>$value) {
if($value) {
$value = str_replace("^","\n",$value);
$array[$k] = explode("|",$value);
}
}
