Jwt 身份验证错误参数 3 传递给 Lcobucci\JWT\Signer\Hmac::doVerify()

Question

I'm working on a project to learn laravel, I saw a couple of tutorials to use jwt auth in this. It was working good but now is show an error not always but I don't know why. this is it:

Argument 3 passed to Lcobucci\JWT\Signer\Hmac::doVerify() must be an instance of Lcobucci\JWT\Signer\Key, null given, called in C:\xampp\htdocs\inmobiliaria\vendor\lcobucci\jwt\src\Signer\BaseSigner.php on line 42

Sometimes it works but not another. so I don't know what can I do. I tried with

1. php artisan cache:clear
2. php artisan config:clear
3. php artisan jwt:secret

but the problem still there, sometimes i get good answer from server(200) but the most part of then al bad (500).

Answer 1

Here's complete snippet

php artisan key:generate
php artisan jwt:secret
php artisan cache:clear
php artisan config:clear

Before run above commands make sure there is install jwt package, than check its config file name jwt.php in config folder.

Answer 2

In fact it's the right thing to solve it:

php artisan key:generate
php artisan jwt:secret

Answer 3

I came across this error when I deployed my application after testing and everything else worked well on the local server.

I noticed the following;

• It's possible that you are getting this error when you uploaded the applications before implementing the JWT and re-uploaded directly via the Cpanel upload without reuploading the .env file.

  • if this is the case, the simplest way to solve this is my merely adding the JWT:key in your .env file (at the bottom) ef

JWT_SECRET=roCZauuldMpw5i4039393939393372y98bEWumqd9ls7Uk8DEpr0gIZ6WIWB

Hope this helps :)

Answer 4

This error can occur when

• JWT_SECRET is missing on the .env
• JWT_SECRET is commented in the .env
• The value of JWT_SECRET is wrong.

In my case, running php artisan jwt:secret it was appending the key on the current JWT_SECRET . So checking my .env file, the value of JWT_SECRET was very long and wrong (it should be 64 chars long).

To solve it:

1. Open the .env and remove the JWT_SECRET value (note that you have to remove it and not comment it).
2. Run php artisan jwt:secret

I have resolved the same on Hostinger - Shared Hosting in a bit different manner than others explained. On shared hosting's user will not have access to shell/cmd/ssh access to the server - So I have executed the commands using composer - Thanks to Ángel Carlos del Pozo Muela for sharing the idea in https://stackoverflow.com/a/48682668 for a different solution but it worked in my case here as well

I have updated the composer.json >> script tag with extra values

"scripts": {
    "pre-generate-key": [
        "@php artisan key:generate",
         "@php artisan cache:clear",
        "@php artisan config:clear"
    ],"post-autoload-dump": [
        "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
        "@php artisan package:discover --ansi"
    ]

Followed by that I have created a new parameter in .env file using going to hostinger file manager and deployed the changes.

 JWT_SECRET={{value}}

on successful completion of deployment - Tested the all service -> all services started working fine - then I removed the "pre-generate-key" bit from composer.json and re-deployed code

Answer 6

php artisan jwt:secret
php artisan config:cache

These both command will be enough

Answer 7

我正在应用程序平台上工作 - Digital Ocean php artisan jwt:secret为我做 -> 它只是生成一个新的秘密，这就是搞砸的（只需检查你的 .env 文件）

Answer 8

This can also happen when using the Laravel Vapor service if you haven't remembered to add the JWT_SECRET to the env file used by Vapor.

In that case just pull the .env file down for the current environment (in this case staging ):

vapor env:pull staging

and add the JWT_SECRECT line to it, followed by a push:

vapor env:push staging

and re-deploy.

I had this problem with my Laravel 8.x and PHP 7.4 so I solved the problem by updating my keys just with these commands:

php artisan key:generate
php artisan jwt:secret
