我收到了一条错误消息：

这是我的php信息：

我使用的是laravel框架(版本5.6)和php7.1。

我想上传一个图片，但我得到了这个错误。

GD Version  bundled (2.1.0 compatible)
GIF Read Support    enabled
GIF Create Support  enabled
PNG Support enabled
libPNG Version  1.6.32
WBMP Support    enabled

我的商店功能：

public function store(CompanyRequest $request)
{
    $all = $request->except(['category-company', 'flag', 'null', 'file', 'producer-company','manager','address','description','phone']);
    $flag = array_values($request->input('flag'));
    $jsonFlag = json_encode($flag);
    $all['flag'] = $jsonFlag;

    if($request->input('manager')){
        $all['manager']=$request->input('manager');
    }
    if($request->input('address')){
        $all['address']=$request->input('address');
    }
    if($request->input('description')){
        $all['description']=$request->input('description');
    }
    if($request->input('phone')){
        $all['phone']=$request->input('phone');
    }
    $file = $request->file('file');
    $name = $file->getClientOriginalName();
    $dir = '/img/company/';
    $path = $dir . time() . $name;
    $thumbnail = $dir . 'tn-' . time() . $name;
    $all['path'] = $path;
    $all['thumbnail'] = $thumbnail;


    $company = Company::create($all);

    $file->move('img/company', time() . $name);

    $img = Image::make('img/company/' . time() . $name);
    $img->resize(100, 100);
    $img->save('img/company/tn-' . time() . $name);


    $company->categories()->sync($request->input('category-company'));
    $company->producers()->sync($request->input('producer-company'));

    return Response::json($company);
}

我也有同样的问题。我花了几个小时的时间追踪到这里，因为图像干预代码使用

$core = @imagecreatefromjpeg($path);

所以错误被抑制了。Apache抛出了500个响应，但是没有关于原因的消息，没有日志，什么也没有。非常令人沮丧！

线索是在上面包含的GD支持输出中，它没有列出JPG。我的是相似的- JPEG被列出，但未显示为已启用：

// I'm using CLI here, use <?php print_r(gd_info()); ?> in an http php page
// to check your web server, CLI PHP config is different to web server config
php -r 'print_r(gd_info());'
Array
(
    [GD Version] => bundled (2.1.0 compatible)
    [FreeType Support] => 
    [T1Lib Support] => 
    [GIF Read Support] => 1
    [GIF Create Support] => 1
    [JPEG Support] =>         // <------ blank
    [PNG Support] => 1
    [WBMP Support] => 1
    [XPM Support] => 
    [XBM Support] => 1
    [WebP Support] => 
    [JIS-mapped Japanese Font Support] => 
)

我在Docker容器中运行PHP/Apache，我的解决方案是在我的Dockerfile中添加JPG支持，正如所描述的在文档的“PHP核心扩展”部分

RUN apt-get update && apt-get install -y \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libpng-dev \
    && docker-php-ext-configure gd --with-freetype --with-jpeg \
    && docker-php-ext-install -j$(nproc) gd

现在GD展示了JPG的支持：

php -r 'print_r(gd_info());' 
Array
(
    [GD Version] => bundled (2.1.0 compatible)
    [FreeType Support] => 1
    [FreeType Linkage] => with freetype
    [T1Lib Support] => 
    [GIF Read Support] => 1
    [GIF Create Support] => 1
    [JPEG Support] => 1         // <------ hurray!
    [PNG Support] => 1
    [WBMP Support] => 1
    [XPM Support] => 
    [XBM Support] => 1
    [WebP Support] => 
    [JIS-mapped Japanese Font Support] => 
)

图像干预终于见效了！
