如何修复Stripe连接时出现的No API key provided错误？

尝试连接并创建Stripe账户时遇到如下错误：

No API key provided. Set your API key when constructing the StripeClient instance, or provide it on a per-request basis using the api_key key in the $opts argument.

以下是相关代码：

SellerController代码 #

        $loginLink = $this->stripeClient->accounts->createloginLink($seller->stripe_connect_id);
        return redirect($loginLink->url);

    public function saveStripeAccount($token){
        $stripeToken = $this->databaseManager->table('stripe_state_tokens')
        ->where('token', '=', $token)
        ->first();

        if(is_null($stripeToken)){

AppServiceProvider代码 #

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;
use Carbon;
use Stripe\StripeCLient;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        $this->app->singleton(StripeClient::class, function(){
            return new StripeClient(config('stripe.secret'));
           });
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
       $this->app->singleton(StripeClient::class, function(){
        return new StripeClient(config('stripe.secret'));
       });
    }
}

修复方案 #

1. 修正AppServiceProvider中的类名拼写错误

代码里use Stripe\StripeCLient;存在拼写错误，应该是Stripe\StripeClient（注意是小写i）。这个错误会导致Laravel容器无法正确解析StripeClient类，最终注入的实例没有携带API密钥。

修改后的AppServiceProvider：

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;
use Carbon;
use Stripe\StripeClient; // 修正拼写错误

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        $this->app->singleton(StripeClient::class, function(){
            return new StripeClient(config('stripe.secret'));
        });
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        // 移除boot方法中的重复单例注册，只保留register方法内的定义即可
        Schema::defaultStringLength(191); // 可选：解决数据库字符串长度限制问题
    }
}

2. 移除重复的单例注册

不需要在boot方法中再次注册StripeClient单例，仅在register方法中注册一次即可，避免重复定义引发冲突。

3. 验证环境变量配置

确保.env文件中正确配置了Stripe密钥：

STRIPE_KEY=你的Stripe公钥
STRIPE_SECRET=你的Stripe密钥

执行php artisan config:clear清除配置缓存，确保新配置生效。

4. 修复代码中的其他拼写错误

• redirectToStripe方法中，return_utl改为return_url，type字段的acccount_onboarding改为account_onboarding（多写了一个c）；
• saveStripeAccount方法中，completed_stripe_unboarding改为completed_stripe_onboarding（拼写错误）。

这些错误虽不直接导致API密钥问题，但会影响后续流程正常运行。
