当前,我正在使用JWT Auth开发Laravel 5.8,所有功能在Postman中都运行良好,但是当我尝试在Browser上进行测试时,我遇到了很多错误,并且一个一个地修复了。现在,当我尝试使用Request传递JSON Web令牌时,出现另一个错误。令牌提供不正确。在完成登录过程后:
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
]);
}
令牌已成功生成。但是当我需要另一个控制器的令牌时,令牌生成失败,这种方法就是一个例子:
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());
}
每次我都想JWTAuth::parseToken();
遇到此错误:
无法从请求中解析令牌
那为什么会这样呢?那我该怎么办?因为在signin
方法中,令牌已成功生成,但是在index
中,我无法访问令牌。感谢您的关注。

令牌需要在每个api请求中通过标头传递
Header Name: Authorization
Expected Value: Bearer --token--
(当然没有)
