JWTAuth身份验证使用用户名而不是电子邮件 - JWTAuth authentication with username instead of email

JWTAuth authentication with username instead of email

是否有任何方法可以在laravel jwt auth中使用用户名（或任何自定义列）而不是电子邮件进行身份验证？

这是现有的代码

public function authenticate(Request $request)
{
    $credentials = $request->only('email', 'password');
    try {
        // verify the credentials and create a token for the user
        if (! $token = JWTAuth::attempt($credentials)) {
            return response()->json(['error' => 'invalid_credentials'], 401);
        }
    } catch (JWTException $e) {
        // something went wrong
        return response()->json(['error' => 'could_not_create_token'], 500);
    }
    // if no errors are encountered we can return a JWT
    return response()->json(compact('token'));
}

我想做一些类似的事情

$credentials = $request->only('username', 'password');

一种方法是将用户名放在电子邮件列中，但这是一个糟糕的解决方案。

我找到了

我们可以从这样的模型（基于自定义字段）中获取用户

//获取一些用户

$user = User::first();

并手动进行身份验证。

$token = JWTAuth::fromUser($user);

环顾四周，似乎可以通过设置$credentials = $request->only('username', 'password');这样的凭据来实现这一点。

所以所有的东西看起来都是这样的：

public function authenticate(Request $request)
    {
        // grab credentials from the request
        //$credentials = $request->only('email', 'password');
        // Change email to username
        $credentials = $request->only('username', 'password');
        try {
            // attempt to verify the credentials and create a token for the user
            if (! $token = JWTAuth::attempt($credentials)) {
                return response()->json(['error' => 'invalid_credentials'], 401);
            }
        } catch (JWTException $e) {
            // something went wrong whilst attempting to encode the token
            return response()->json(['error' => 'could_not_create_token'], 500);
        }
        // all good so return the token
        return response()->json(compact('token'));
    }

//Use case for login with email or username    
public function login(Request $request){
            // Request input contains username, email and password
            if ($request->has(['username', 'email', 'password'])) {
                $credentials = $request->only('email', 'password');
            } // Request input contains `enter code here`username and password
            elseif ($request->has(['username', 'password'])) {
                $credentials = $request->only('username', 'password');
            } // Request input contains email and password
            elseif ($request->has(['email', 'password'])) {
                $credentials = $request->only('email', 'password');
            }
            else {
                $credentials = $request->only('email', 'password');
            }
            try {
               if (!$token = JWTAuth::attempt($credentials)) {
                return response()->json(['invalid_email_or_password']);
               }
            } catch (JWTAuthException $e) {
                return response()->json(['failed_to_create_token'], 500);
            }
            return response()->json(compact('token'));
        }
