目前我正在使用 JWT Auth 开发 Laravel 5.8,一切都在 Postman 中运行,但是当我尝试在浏览器上进行测试时,我遇到了很多错误,并且已经一一修复。现在,当我尝试使用 Request 传递 JSON Web Token 时出现另一个错误。未正确提供令牌。在我登录过程之后:
public function signin(Request $request)
{
$this->validate($request, [
'username' => 'required',
'password' => 'required'
]);
// grab credentials from the request
$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, username and password dismatches. Or username may not registered.',
'status' => '401'
], 401);
}
} catch (JWTException $e) {
// something went wrong whilst attempting to encode the token
return response()->json(['error' => 'could_not_create_token'], 500);
}
return response()->json([
'token' => $token
]);
}
令牌生成成功。但是当我需要令牌到另一个控制器时,令牌生成失败,一个例子就是这个方法:
public function index(Request $request)
{
// this will set the token on the object
JWTAuth::parseToken();
// and you can continue to chain methods
$user = JWTAuth::parseToken()->authenticate();
$token = JWTAuth::getToken();
die($token);
try {
if (! $user = JWTAuth::parseToken()->authenticate()) {
return response()->json(['user_not_found'], 404);
}
} catch (Tymon\JWTAuth\Exceptions\TokenExpiredException $e) {
return response()->json(['token_expired'], $e->getStatusCode());
} catch (Tymon\JWTAuth\Exceptions\TokenInvalidException $e) {
return response()->json(['token_invalid'], $e->getStatusCode());
} catch (Tymon\JWTAuth\Exceptions\JWTException $e) {
return response()->json(['token_absent'], $e->getStatusCode());
}
每次我想JWTAuth::parseToken();
我都会收到这个错误:
无法从请求中解析令牌
那么为什么会这样呢?我该怎么办?因为在signin
方法中,成功生成了token,但是在index
我无法访问token。感谢您的关注。
