Cakephp4 不接受内容类型 application/json；字符集=utf-8

Question

我将我的应用程序从 Cakephp3 升级到 cakephp4，但不幸的是，由于后勤问题，我无法相应地更新 android 应用程序。 android 应用程序使用 Content-Type application/json; charset=utf-8 进行 HTTP 调用，而 cakephp4 不断抛出错误请求。在我收集所有平板电脑并相应地更新它们之前，有没有办法让 cakephp4 接受这个标头作为权宜之计？

以下是错误日志：

下面是token方法

  public function token()
  {
    $this->getRequest()->allowMethod('post');

    $employee = $this->Employees
        ->find()
        ->select(['Employees.id','Employees.project_id', 'Employees.name'])
        ->where(['Employees.pin_code' => $this->request->getData('pin_code')])
        ->firstOrFail()
        ->toArray();

      $sites = TableRegistry::getTableLocator()->get('Sites');
      $currentSite = array('id' => 0, 'name'=> 0);
      $currentTransactionId = 0;
      $transactions = TableRegistry::getTableLocator()->get('Transactions');
      $previousTransaction = $transactions->find()->where([
        'Transactions.employee_id' => $employee['id']
      ])->order([
        'Transactions.created' => 'DESC'
      ])->first();
      if(!empty($previousTransaction) && empty($previousTransaction->photo_out)) {
        $currentSite = $sites->get($previousTransaction->site_id);
        $currentTransactionId = $previousTransaction->id;
      }
      $this->set([
        'success' => true,
        'employee' => $employee,
        'current_site' => $currentSite,
        'sites' => $sites->find()->matching('Projects', function ($q) use ($employee) {
          return $q->where(['Projects.id' => $employee["project_id"]]);
        }),
        'transaction_id' => $currentTransactionId,
        'data' => [
          'token' => JWT::encode([
              'sub' => $employee['id'],
              'exp' =>  time() + 604800
          ],
          Security::getSalt())
        ],
      ]);
      // Specify which view vars JsonView should serialize.
      $this->viewBuilder()->setOption('serialize', ['success', 'employee', 'current_site', 'sites', 'transaction_id', 'data']);
  }

是的，中间件是在 src/Application.php 中设置的

公共函数中间件(MiddlewareQueue $middlewareQueue): MiddlewareQueue { $中间件队列

    // Catch any exceptions in the lower layers,
    // and make an error page/response
    ->add(new ErrorHandlerMiddleware(Configure::read('Error')))

    // Handle plugin/theme assets like CakePHP normally does.
    ->add(new AssetMiddleware([
        'cacheTime' => Configure::read('Asset.cacheTime'),
    ]))

    // Add routing middleware.
    // If you have a large number of routes connected, turning on routes
    // caching in production could improve performance. For that when
    // creating the middleware instance specify the cache config name by
    // using it's second constructor argument:
    // `new RoutingMiddleware($this, '_cake_routes_')`
    ->add(new RoutingMiddleware($this))

    // Parse various types of encoded request bodies so that they are
    // available as array through $request->getData()
    // https://book.cakephp.org/4/en/controllers/middleware.html#body-parser-middleware
    ->add(new BodyParserMiddleware())

    // Cross Site Request Forgery (CSRF) Protection Middleware
    // https://book.cakephp.org/4/en/controllers/middleware.html#cross-site-request-forgery-csrf-middleware
    // ->add(new CsrfProtectionMiddleware([
    //     'httponly' => false,
    // ]))

    // Add the middleware to the middleware queue
    ->add(new AuthenticationMiddleware($this));

return $middlewareQueue;

}

下面是测试方法

  public function testJwtTokenPost() {
    $this->configRequest([
      'headers' => [
        'Accept' => 'application/json',
        'Content-Type' => 'application/json; charset=utf-8'
      ]
    ]);
    // $this->enableCsrfToken();
    $this->post('/api/employees/token', [
      'pin_code' => '1001'
    ]);
    $this->assertResponseOk();
    $this->assertResponseContains('success');
    $this->assertResponseContains('employee');
    $this->assertResponseContains('current_site');
    $this->assertResponseContains('transaction_id');
    $this->assertResponseContains('sites');
    $this->assertResponseContains('data');
  }

下面是我的邮递员 json 调用

Answer 1

在测试非application/x-www-form-urlencoded 请求时，您必须将数据作为字符串传递，因为测试用例无法可靠地假设如何将数据本身转换为字符串。

即，将 JSON 字符串作为 POST 数据传递，而不是数组，字符串是 PHP 为实际 HTTP 请求公开application/json 数据的方式：

$this->post('/api/employees/token', json_encode([
    'pin_code' => '1001'
]));

无需为此进一步配置body parser middleware，它支持开箱即用的JSON。
