我面临着一个302重定向问题，而发布的数据在更新所有更新成功，除了图像，我得到302和我的页面重定向。
这是我的表格代码：

{!! Form::model($post, ['method' => 'PATCH','route' => ['posts.update', $post->id],'data-parsley-validate' => '','class' => 'form-horizontal','files'=>true,'name'=>'updateabout']) !!}

<div class="col-md-8">

        <div class="col-md-10">

        </div>

{!! Form::close() !!}

我的控制器：

public function update(Request $request, $id)
{
    // Validate the data
    $postdata = Post::find($id);

    //print_r($post);

    if ($request->input('slug') == $postdata->slug) {
        //echo 'slug match';
        //exit();
        $this->validate($request, [
            'title'            => 'required|max:255',
            'category_id'      => 'required|integer',
            'long_description' => 'required',
        ]);
    } else {
        //echo 'new slug matching';
        //exit();
        $this->validate($request, [
            'title'            => 'required|max:255',
            'slug'             => 'required|alpha_dash|min:5|max:255|unique:posts,slug',
            'category_id'      => 'required|integer',
            'long_description' => 'required',
        ]);
    }

    if ($request->hasFile('imagemain')) {

        //echo 'request has old file to unlink ';
        // exit();
        //unlink($request->get('image'));
        // Get filename with the extension
        $filenameWithExt = $request->file('imagemain')->getClientOriginalName();
        // Get just filename
        $filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
        // Get just ext
        $extension = $request->file('imagemain')->getClientOriginalExtension();
        $fileNameToStore = $filename . '_' . time() . '.' . $extension;
        // Upload Image
        $path = $request->file('imagemain')->move('public/blogsimages', $fileNameToStore);
        // Filename to store
        echo $fileNameToStore = $path;
    } else {
        $fileNameToStore = $request->input('imageold');
        // exit();
    }

    // Save the data to the database
    $post = Post::find($id);

    $post->title = $request->input('title');
    $post->slug = $request->input('slug');
    $post->category_id = $request->input('category_id');
    $post->description = $request->input('description');
    $post->short_description = $request->input('short_description');
    $post->date = $request->input('date');
    $post->image = $fileNameToStore;
    $post->meta_title = $request->input('meta_title');
    $post->meta_keywords = $request->input('meta_keywords');
    $post->authorname = $request->input('authorname');

    $post->save();

    if (isset($request->tags)) {
        $post->tags()->sync($request->tags);
    } else {
        $post->tags()->sync([]);
    }

    // set flash data with success message
    Session::flash('success', 'This post was successfully saved.');

    // redirect with flash data to posts.show
    return redirect()->route('posts.show', $post->id);
}

当我发布数据时，除了显示302的图片和表格外，所有内容都按照要求更新，这里是屏幕截图：

我的路线是： Route::resource('posts', 'PostController');

302状态代码含义：
从这里开始：
超文本传输协议（http）302找到重定向状态响应代码指示所请求的资源已被临时移动到由位置报头给定的url
因此，在控制器的最后一行中，您正在执行重定向：

return redirect()->route('posts.show', $post->id);

另外，当laravel验证失败时，它会自动重定向您。

我认为验证脚本有错误，请尝试代码

public function update(Request $request, $id)
{
    // Validate the data
    $postdata = Post::find($id);

    //WITHOUT VALIDATION

    if ($request->hasFile('imagemain')) {

        //echo 'request has old file to unlink ';
        // exit();
        //unlink($request->get('image'));
        // Get filename with the extension
        $filenameWithExt = $request->file('imagemain')->getClientOriginalName();
        // Get just filename
        $filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
        // Get just ext
        $extension = $request->file('imagemain')->getClientOriginalExtension();
        $fileNameToStore = $filename . '_' . time() . '.' . $extension;
        // Upload Image
        $path = $request->file('imagemain')->move('public/blogsimages', $fileNameToStore);
        // Filename to store
        echo $fileNameToStore = $path;
    } else {
        $fileNameToStore = $request->input('imageold');
        // exit();
    }

    // Save the data to the database
    $post = Post::find($id);

    $post->title = $request->input('title');
    $post->slug = $request->input('slug');
    $post->category_id = $request->input('category_id');
    $post->description = $request->input('description');
    $post->short_description = $request->input('short_description');
    $post->date = $request->input('date');
    $post->image = $fileNameToStore;
    $post->meta_title = $request->input('meta_title');
    $post->meta_keywords = $request->input('meta_keywords');
    $post->authorname = $request->input('authorname');

    $post->save();

    if (isset($request->tags)) {
        $post->tags()->sync($request->tags);
    } else {
        $post->tags()->sync([]);
    }

    // set flash data with success message
    Session::flash('success', 'This post was successfully saved.');

    // redirect with flash data to posts.show
    return redirect()->route('posts.show', $post->id);
}

这会解决你的问题。
