如何在FedexRest库中设置运单的SignatureOption（DIRECT/ADULT_ONLY）

你需要通过setSpecialServices方法来添加签名服务，这个库提供了SignatureOptionType枚举类，里面包含DIRECT和ADULT_ONLY这两个签名选项常量。

修改后的完整代码如下：

// 确保已引入对应的枚举类
use WhatArmy\FedexRest\Services\Ship\Enums\SignatureOptionType;

$this->request
    ->setRecipients(
        (new Person)
            ->setPersonName($this->recipient->name)
            ->setPhoneNumber($this->recipient->phone_number)
            ->setCompanyName($this->recipient->company_name)
            ->withAddress(
                (new Address())
                    ->setCity($this->recipient->city)
                    ->setStreetLines($this->recipient->address)
                    ->setCountryCode($this->recipient->country)
                    ->setPostalCode($this->recipient->postal_code)
            )
    )
    ->setLineItems((new Item())
        ->setSequenceNumber(1)
        ->setItemDescription('Product 1')
        ->setWeight(
            (new Weight())
                ->setValue(1)
                ->setUnit(WeightUnits::_KILOGRAM)
        )
        ->setDimensions((new Dimensions())
            ->setWidth(15)
            ->setLength(10)
            ->setHeight(15)
            ->setUnits(LinearUnits::_CENTIMETER)
        )
    )
    // 设置签名选项
    ->setSpecialServices([
        'signatureOption' => SignatureOptionType::DIRECT,
        // 若需成人签名，替换为下面一行
        // 'signatureOption' => SignatureOptionType::ADULT_ONLY
    ])
    
    ->request();

补充说明： #

• 签名选项属于Fedex的特殊服务范畴，因此需要通过setSpecialServices传入关联数组来指定。
• 必须先引入SignatureOptionType枚举类，否则会出现未定义常量的错误。
• 切换签名类型只需替换枚举常量即可，DIRECT对应直接签名，ADULT_ONLY对应仅成人签名。
