In this paper, an example is given to describe the function of uploading pictures to 7 cows realized by Laravel framework. Share it for your reference, as follows:

New project

Here directly with a new Laravel 5.3 project for demonstration, other versions are 1 will not affect the function, at most is the routing location is not 1. Small partners of existing projects can skip the second paragraph directly. 


#  New project 
laravel new laravel-qiniu
cd laravel-qiniu

Install Laravel7 Bull Expansion Pack

After Composer installation: 


composer require zgldh/qiniu-laravel-storage

Then register the service provider in config/app. php: 


zgldh\QiniuStorage\QiniuFilesystemServiceProvider::class

Next, add a 7-cow configuration to disks in config/filesystems. php: 


'qiniu' => [
  'driver' => 'qiniu',
  'domains' => [
    'default'  => 'xxxxx', // Yours 7 Cow domain name 
    'https'   => 'xxxxx',     // Yours HTTPS Domain name 
    'custom'  => 'xxxxx',   // Your custom domain name 
   ],
  'access_key'=> '', //AccessKey
  'secret_key'=> '', //SecretKey
  'bucket'  => '', //Bucket Name 
  'notify_url'=> '', // Persistence processing callback address 
],

OK, the installation of the expansion package is introduced here for the time being. Next, we will go to 7 Niu to register an account and improve the above configuration.

7 cow account registration and configuration

Go to 7 Niu to register an account first. Clicking on the registration in official website will let us choose the user type. Here I will choose the individual user.

Next, according to the process, the input registration will be OK, so I won't show it to you. Since my mobile phone number has been registered, I can only show you 1 example of the storage object I have added.

OK, simply show you the default domain name of 7 cows and where to see the custom domain name. Let's show you the location of the key of 7 cows:

Click on the secret key management, and you can see the secret key of 7 cows:

Configuration of 7 cattle in Laravel

Where the relevant configurations are already described above, we will now use these configurations in Laravel:

Upload pictures to 7 cows

Simple with an example to demonstrate the front-end upload pictures to the background, with the extension of 7 cows upload pictures

Create a new index. blade. php view under resources\ views 


<!DOCTYPE html>
<html>
<head>
  <title> Upload pictures </title>
</head>
<body>
  <form method="post" action="" enctype="multipart/form-data">
    <input type="file" name="file">
    <button type="submit"> Upload pictures </button>
  </form>
</body>
</html>

The page code is simple and has no style (please forgive me for being lazy). Create a new UplaodController upload file controller: 


php artisan make:controller UploadController

Implement the upload method: 


<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use zgldh\QiniuStorage\QiniuStorage;
class UploadController extends Controller
{
  /**
   *  Upload files to 7 Cattle 
   * @author  Gao Wei 
   * @date  2016-11-09T16:58:37+0800
   * @param Request         $request [description]
   * @return [type]              [description]
   */
  public function uploadFile(Request $request)
  {
    //  Determine whether a file is uploaded 
    if ($request->hasFile('file')) {
      //  Get a file ,file Corresponding to the front-end form upload input Adj. name
      $file = $request->file('file');
      // Laravel5.3 More in the middle 1 A writing method 
      // $file = $request->file;
      //  Initialization 
      $disk = QiniuStorage::disk('qiniu');
      //  Rename file 
      $fileName = md5($file->getClientOriginalName().time().rand()).'.'.$file->getClientOriginalExtension();
      //  Upload to 7 Cattle 
      $bool = $disk->put('iwanli/image_'.$fileName,file_get_contents($file->getRealPath()));
      //  Judge whether the upload is successful 
      if ($bool) {
        $path = $disk->downloadUrl('iwanli/image_'.$fileName);
        return ' Upload successful, picture url:'.$path;
      }
      return ' Upload failed ';
    }
    return ' No files ';
  }
}

Add a route: 


//  Upload page view 
Route::get('/upload',function ()
{
  return view('index');
});
// form Commit to controller route 
Route::post('upload','UploadController@uploadFile');

View page (resources\ views\ index. blade. php): 


<!DOCTYPE html>
<html>
<head>
  <title> Upload pictures </title>
</head>
<body>
  <form method="post" action="{{url('upload')}}" enctype="multipart/form-data">
    {{csrf_field()}}
    <input type="file" name="file">
    <button type="submit"> Upload pictures </button>
  </form>
</body>
</html>

OK, refresh the page to see the uploaded url address. Here is just a demonstration of the simplest example, routing definition, view style, and logical layer to deal with everyone in accordance with their own projects on the line
