PHP about AIP image upload interface

Simple case of PHP upload:

Html file:

         

Style related:

On the mobile phone, click the upload button and the camera will pop up:

<input type="file" accept="image/*;capture=camera">直接调用相机
　　　　　　　　　　　　<input type="file" accept="image/*" />调用相机 图片或者相册

PHP file:

<?php $file = $_FILES[&#39;file&#39;];//得到传输的数据

//得到文件名称$name = $file[&#39;name&#39;];$type = strtolower(substr($name,strrpos($name,&#39;.&#39;)+1)); //得到文件类型，并且都转化成小写$allow_type = array(&#39;jpg&#39;,&#39;jpeg&#39;,&#39;gif&#39;,&#39;png&#39;); //定义允许上传的类型
//判断文件类型是否被允许上传if(!in_array($type, $allow_type)){    //如果不被允许，则直接停止程序运行
    return ;
}//判断是否是通过HTTP POST上传的if(!is_uploaded_file($file[&#39;tmp_name&#39;])){    //如果不是通过HTTP POST上传的
    return ;
}$upload_path = "./img/"; //上传文件的存放路径
//开始移动文件到相应的文件夹if(move_uploaded_file($file[&#39;tmp_name&#39;],$upload_path.$file[&#39;name&#39;])){    echo "Successfully!";
}else{    echo "Failed!";
}?>

A simple case of uploading using thinkphp upload class:

    
      = 'maxSize'    =>    3145728,         
        'exts'       =>    ('jpg', 'gif', 'png', 'jpeg'),
        'rootPath'   =>    './Public/Uploads/info/',
        'savePath'   =>    '',                          
        'saveName'   =>    ('uniqid',''),
        'autoSub'    =>    ,                       
        'subName'    =>    ('date','Ymd'),  upload(['result'] = 1['imgurl'] = ''['msg'] = '' =  = ->upconfig['rootPath'] . ->upconfig['savePath'(!( = (, 0777, (!
                ['result'] = 0['msg'] = "创建保存图片的路径失败！"
             =  \Think\Upload(->

(!
                ['result'] = 0['msg'] = ->
                 =  ->upconfig['rootPath'] . ['savepath'].['savename' = ('./', '/', ['result'] = 1['imgurl'] = (0 
         = ->upload(['attorney']);

Mobile app upload image example: API interface:

Question: When APP uploads avatars, how should php, as the API end, receive image information?

The upload part of the code is not a problem, the main problem is how the server side can receive the image information from the APP side. Under the B/S architecture, you can set enctype="multipart/form-data" directly through the form form, and the image information will be in the $_FILES array. So is this also true in C/S mode?

Answer 1 (see method 1): Generally, binary stream transmission is used. The client transmits binary data, the server receives it, and then file_put_contents is written to the file. That's it. The file name format and where to put the file are all defined by yourself.

Answer 2 (see method 2): The Android or IOS client simulates an HTTP Post request to the server, and the server receives the corresponding Post request (through $_FILES Obtain image resources) and return response information to the client. (This method is the same as the method of obtaining Html submission)

Method 1: Base64 encrypt the image into a string for transmission

Description: IOS or Android side: Base64 encode the image to obtain the string, and pass it to the interface

Interface side: Base64 decode the received string, and then upload it to the specified location through the file_put_contents function

    /**
     * 图片上传
     * @param $imginfo - 图片的资源，数组类型。['图片类型','图片大小','图片进行base64加密后的字符串']
     * @param $companyid - 公司id
     * @return mixed     */
    public function uploadImage( $imginfo , $companyid ) {        $image_type = strip_tags($imginfo[0]);  //图片类型
        $image_size = intval($imginfo[1]);  //图片大小
        $image_base64_content = strip_tags($imginfo[2]); //图片进行base64编码后的字符串

        $upload = new UploaderService();        $upconfig = $upload->upconfig;        if(($image_size > $upconfig['maxSize']) || ($image_size == 0)) {            $array['status'] = 13;            $array['comment'] = "图片大小不符合要求！";            return $array;
        }        if(!in_array($image_type,$upconfig['exts'])) {            $array['status'] = 14;            $array['comment'] = "图片格式不符合要求！";            return $array;
        }        // 设置附件上传子目录
        $savePath = 'bus/group/' . $companyid . '/';        $upload->upconfig['savePath'] = $savePath;        //图片保存的名称
        $new_imgname = uniqid().mt_rand(100,999).'.'.$image_type;        //base64解码后的图片字符串
        $string_image_content = base64_decode($image_base64_content);        // 保存上传的文件
        $array = $upload->upload($string_image_content,$new_imgname);        return $array;
    }

    // 上传配置信息
    public $upconfig = array(        'maxSize'    =>    3145728,         //3145728B（字节） = 3M
        'exts'       =>    array('jpg', 'gif', 'png', 'jpeg'),//        'rootPath'   =>    './Public/Uploads/info/',
        'rootPath'   =>    'https://www.eyuebus.com/Public/Uploads/info/',
    );    /**

     * @param $new_imgname - 图片的名称，如：57c14e197e2d1744.jpg
     * @return mixed     */
    public function upload($string_image_content,$new_imgname) {        $res['result'] = 1;        $res['imgurl'] = '';        $res['comment'] = '';        do {            $ret = true;            $fullPath = $this->upconfig['rootPath'] . $this->upconfig['savePath'];            if(!file_exists($fullPath)){                $ret = mkdir($fullPath, 0777, true);
            }            if(!$ret) {                // 上传错误提示错误信息
                $res['result'] = 12;                $res['comment'] = "创建保存图片的路径失败！";                return $res;                break;
            }            //开始上传
            if (file_put_contents($fullPath.$new_imgname, $string_image_content)){                // 上传成功 获取上传文件信息
                $res['result'] = 0;                $res['comment'] = "上传成功！";                $res['imgname'] = $new_imgname;
            }else {                // 上传错误提示错误信息
                $res['result'] = 11;                $res['comment'] = "上传失败！";
            }


        } while(0);        return $res;
    }

方式二：Android或者IOS客户端模拟一个HTTP的Post请求到服务器端，服务器端接收相应的Post请求后（通过$_FILES获取图片资源），返回响应信息给给客户端。（这一种方式和获取Html方式提交的方法一样）

移动端需要请求一个URL，这个URL接收POST过去的数据，比如：http://www.apixxx.net/Home/Uploader/uploadPrepare

    public function uploadPrepare() {        $array = array();        $post_log = print_r($_POST, true);        Log::record($post_log, 'DEBUG');        $file_log = print_r($_FILES, true);        Log::record($file_log, 'DEBUG');        $token = $_POST['token'];        $token_str          = jwt_decode($token);$user_type          = $token_str['user_type'];

        // 设置附件上传子目录
        if($user_type == 1) {            $savePath = 'travel/group/' . $user_companyid . '/';
        }elseif ($user_type == 2) {            $savePath = 'bus/group/' . $user_companyid . '/';
        }elseif ($user_type == 3) {            $savePath = 'driver/group/' . $user_companyid . '/';
        }else {            $array['status'] = 3;            $array['comment'] = '非法用户！';            return $array;
        }        $this->upconfig['savePath'] = $savePath;        // 保存上传的文件(单张)
//        $res = $this->upload($_FILES['file']);

    
        // 保存上传的文件（多张） 移动端的表单name=“xxx[]”，支持多张图片
        $res = $this->upload();        $array['status'] = $res['status'];        $array['comment'] = $res['comment'];        $array['responseParameters']['img_url'] = $res['img_url'];        echo json_encode($array);
    }    protected function upload() {        $res['status'] = 1;        $res['imgurl'] = '';        $res['comment'] = '';        do {            $ret = true;            $fullPath = $this->upconfig['rootPath'] . $this->upconfig['savePath'];            if(!file_exists($fullPath)){                $ret = mkdir($fullPath, 0777, true);
            }            if(!$ret) {                // 上传错误提示错误信息
                $res['status'] = 1;                $res['comment'] = "创建保存图片的路径失败！";                break;
            }            // 实例化上传类
            $upload = new \Think\Upload($this->upconfig);//            // 上传单个文件
//            $info = $upload->uploadOne($file);

            // 上传多个文件
            $infos = $upload->upload();            // 上传的图片数量
            $file_count = 0;            foreach ($_FILES as $file_k => $file_v) {                foreach ($file_v["size"] as $k => $v) {                    if($v == 0) {                        continue;
                    }                    $file_count += 1;
                }
            }            Log::record("info_log", 'DEBUG');            $info_log = print_r($infos,true);            Log::record($info_log, 'DEBUG');            if(!$infos) {                // 上传错误提示错误信息
                $res['status'] = 2;                $res['comment'] = $upload->getError();
            } else {                // 获取的上传成功的图片数量
                $info_count = 0;                // 上传成功 获取上传文件信息
                foreach($infos as $k => $v) {                    $imgurl[$v['key']][] =  str_replace('./', '/', $this->upconfig['rootPath'] . $v['savepath'].$v['savename']);                    $info_count += 1;
                }                if($file_count != $info_count) {                    $res['status'] = 1;                    $res['comment'] = "上传失败！上传的多张图片，没有全部上传成功";
                }else {                    $res['status'] = 0;                    $res['comment'] = "上传成功！";                    $res['img_url'] = $imgurl;
                }
            }

        } while(0);        return $res;
    }
