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);
}
})
