php 简单实现上传文件到七牛

一、前端

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no">
    <title>上传图片</title>
    <style>
        button{cursor: pointer;height: 30px;}
        .item-line{display: flex;flex-wrap: wrap;}
    </style>
</head>
<body>
<div class="weui-cells weui-cells_form">
    <form action="HandleImg.php" method="post" enctype="multipart/form-data">
        <div class="body">
            <div class="item">
                <div class="item-line"><p>图片1:</p>&nbsp;<p><input type="file" name="img1" ></p></div>
                <div class="item-line"><p>图片2:</p>&nbsp;<p><input type="file" name="img2" ></p></div>
            </div>
            <div class="but-body">
                <button type="submit">提交上传</button>
                <a href="/">取消</a>
            </div>
        </div>
    </form>
</div>
</body>
</html>

二、处理里图片

<?php

if(isGet()){
    header("location:/");
}

include 'service/UploadService.php';

header('Content-Type:text/html; charset=utf-8;');

$servername = "127.0.0.1";

$username = "root";

$password = "root";

$dbname = 'jiacheng';

//$servername = "156.232.241.211";
//$username = "a240386333";
//$password = "chen123";
//$dbname = "a240386333";

$conn = mysqli_connect($servername, $username, $password, $dbname);
// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}


if(isset($_FILES) && !empty($_FILES)){
    $file=$_FILES;
//    print_r($file);

    $data=['url1'=>'','url2'=>''];
    if($file['img1']['error']==4 && $file['img2']['error']==4){
        jump();
        die;
    }
    if($file['img1']['error']==0){
        $res=service\UploadService::upload($file['img1']);
        if($res['code']==0){
            $data['url1']=$res['data']['url'];
        }
    }

    if($file['img2']['error']==0){
        $res=service\UploadService::upload($file['img2']);
//        echo '$res';
//        print_r($res);
        if($res['code']==0){
            $data['url2']=$res['data']['url'];
        }
    }
//    echo 'data:';
//    print_r($data);

    update($conn,$data);
    die;
}

jump();

function update($conn,$data){

    if($data['url1']==''&&$data['url2']==''){
        jump('上传失败');
        die;
    }
    else if($data['url1']!=''&&$data['url2']!=''){
        $updatesql="UPDATE chen set u1='".$data['url1']."' , u2='".$data['url2']."' where id=0";
    }
    else if($data['url1']!=''&&$data['url2']==''){
        $updatesql="UPDATE chen set u1='".$data['url1']."' where id=0";
    }
    else if($data['url1']==''&&$data['url2']!=''){
        $updatesql="UPDATE chen set u2='".$data['url2']."' where id=0";
    }

    $retval=mysqli_query($conn,$updatesql);
    if(!$retval)
    {
        jump('更新失败',1);
        die;
    }

    $conn->close();
    jump('更新成功',0);
    die;
}

function jump($msg='请选择图片',$code=1){
    $url=$code==1?'/upload.html':'/upload.html';
    $js="<script>
        alert('{$msg}');
        setTimeout(function(){
            location.href='{$url}';
        },1500)
    
    </script>";
    echo $js;
}

//是否是GET提交
function isGet(){
    return $_SERVER['REQUEST_METHOD'] == 'GET' ? true : false;
}

三、七牛上传核心文件

sdk地址 ： https://github.com/qiniu/php-sdk

   /**
     * 上传资源
     * @param $file
     * @return array
     * @throws \Exception
     */
    public static function upload($file){
        try{
            $accessKey = '';//AK
            $secretKey = '';//SK
            $qn_domain='';//绑定域名
            $auth=new Auth($accessKey,$secretKey);
            $bucket='';//存储空间
            $token = $auth->uploadToken($bucket);
            $uploadMgr = new \Qiniu\Storage\UploadManager();
            $filePath = $file['tmp_name'];//'./php-logo.png';  //接收图片信息
            if($file['type']=='video/mp4'){
                $key = 'video'.time().'.mp4';
            }elseif($file['type']=='audio/mp3'){
                $key = 'audio'.time().'.mp3';
            }else{
                $key = 'png'.time().'.png';
            }
            list($ret, $err) = $uploadMgr->putFile($token, $key, $filePath);

            if($err!=null){
                return ["code"=> 1,"msg"=> $err];
            } else {
                //返回图片的完整URL
                $url ="http://{$qn_domain}/".$ret['key'];
                $data=['url'=>$url];
                return ['code'=>0,'msg'=>'上传成功','data'=>$data];
            }
        }catch (\Exception $e){
            return ["code"=> 1,"msg"=> $e->getMessage()];
        }

    }
