文件的上传和接收代码

1.二进制上传

1. 1 php接收

 public function upload()
 {
        // 获取表单上传文件
        $file = request()->file('file');
        // 移动到上传临时目录
        $info = $file->rule('uniqid')->move(get_image_path(config('image_folder_temp')));
        if ($info) {
            return $this->returnOk(array('msg' => '上传成功', 'file_name' => $info->getSaveName()));
        } else {
            return $this->returnErr('上传失败，请重试！');
        }
    }

1.2 iOS上传

NSString *URL = [NSString stringWithFormat:@"%@%@",[HSApi ShareApi].HS_URL_HEAD,@"file/upload"];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];//设置服务器允许的请求格式内容
[manager POST:URL parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
    [formData appendPartWithFileData:files name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpg"];
    
} progress:^(NSProgress * _Nonnull uploadProgress) {
    
} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSDictionary *JSON = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
    //[HSCoverView showMessage:@"上传成功"];
    success(JSON[@"file_name"]);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    
}];

1.3 前端canvas画布生成图片上传

canvas.toBlob(function (blob) {
// 图片ajax上传
    var fd = new FormData();
    fd.append('file', blob);
    $.ajax({
        type: 'POST',
        url: 'http://appdev.hskaoyan.com/xxx/file/upload',
        data: fd,
        processData: false,
        contentType: false
    }).done(function (data) {
        console.log(data);
    });
}, 'image/jpeg');

2. base64 加密

2.1 php接收

  public function saveBaseImage(Request $request)
  {
        if ($request->isPost()) {
            $base64_img = trim($request->param('image'));
            if (!preg_match('/^(data:\s*image\/(\w+);base64,)/', $base64_img, $result)) {
                // 匹配图片文件失败
                return $this->returnErr('不支持的文件格式，请重试！');
            }
            $img_ext = $result[2];
            if (!in_array($img_ext, array('jpeg', 'jpg', 'png'))) {
                // 文件类型错误，不支持该类型
                return $this->returnErr('仅支持jpg、jpeg、png的图片！');
            }
            // 保存临时图片
            $src_name = config('image_folder_temp') . uniqid() . '.' . $img_ext;
            $src_path = get_image_path($src_name, '', get_server_name());
            if (!file_put_contents($src_path, base64_decode(str_replace($result[1], '', $base64_img)))) {
                return $this->returnErr('上传头像失败，请重试！');
            }
            return $this->returnOk($src_name);
        }
    }

2.2 canvas画布转图片上传

var dataURL = canvas.toDataURL("image/png");
$.ajax({
    async: false,
    url: '/admin/image/saveBaseImage',
    data: {image: dataURL, img_folder: '/tmp/'},
    type: "post",
    success: function (data) {
        alert(data);
    }
})
