如何解决“无效的报头值:必须是字符串或字符串数​​组"在Laravel [英] How to fix "Invalid header value: must be a string or array of strings" in Laravel

问题描述

我在本地没有的产品服务器上遇到了问题. Laravel给我发送了一个错误，该错误指示一个标题问题.我认为这是一个Apache问题.

I have an issue on a prod server that I don't have in local. Laravel send me an error which says that there is a header issue. I think this is an Apache issue.

我在Mamp的本地计算机上工作. Laravel将OAuth与Laravel Passport一起使用.我已经在本地计算机上尝试过，并且可以正常工作.我也在Apache服务器上运行.

I work on my local machine with Mamp. Laravel is using OAuth with Laravel Passport. I've tried on my local machine and it's working. I'm running on a Apache server too.

在生产服务器上，只要我要登录我的应用程序，就会出现此错误:

On my production server, as soon as I want to login on my application, I have this error :

错误500:InvalidArgumentException，无效的标头值:必须为 字符串或字符串数​​组；不能为空数组.

ERROR 500 : InvalidArgumentException, Invalid header value: must be a string or array of strings; cannot be an empty array.

它在Laravel Zendframwork供应商的MessageTrait.php line 389中.

And it's in MessageTrait.php line 389 from Laravel Zendframwork vendor.

也许这只是服务器上的一个模块?

Maybe it's just a module on the server ?

谢谢

推荐答案

我遇到了同样的问题，我的解决方案是将下一个软件包降级到该特定版本，因为那是我的项目中正在使用的版本:

I was having the same problem, my solution was to downgrade the next packages to that specific version because that was the version that was working in my project:

composer require symfony/http-kernel:3.4.20
composer require symfony/http-foundation:3.4.20
composer require symfony/psr-http-message-bridge:1.1.0

我希望它对您有用.
