php – Symfony2路由：两个可选参数 – 至少需要一个

我正在尝试在symfony2中设置一些路由,具体如下：

www.myaweSEOmesite.com/payment/customer/{customernumber}/{invoicenumber}

这两个参数是可选的 – 因此以下情况必须工作：

www.myaweSEOmesite.com/payment/customer/{customerNumber}/{invoiceNumber}
www.myaweSEOmesite.com/payment/customer/{customerNumber}
www.myaweSEOmesite.com/payment/customer/{invoiceNumber}

我根据symfony2 doc设置了route.yml.

payment_route:
pattern:  /payment/customer/{customerNumber}/{invoiceNumber}
defaults: { _controller: PaymentBundle:Index:payment,customerNumber: null,invoiceNumber: null }
requirements:
    _method:  GET

到目前为止,问题是,如果两个参数都丢失或是空,则该路由不起作用.所以

www.myaweSEOmesite.com/payment/customer/

不应该工作有没有办法这样做与Symfony2？

您可以在两条路线中定义它,以确保只有1条斜线.

payment_route_1:
    pattern:  /payment/customer/{customerNumber}/{invoiceNumber}
    defaults: { _controller: PaymentBundle:Index:payment,invoiceNumber: null }
    requirements:
        customerNumber: \d+
        invoiceNumber: \w+
        _method:  GET

payment_route_2:
    pattern:  /payment/customer/{invoiceNumber}
    defaults: { _controller: PaymentBundle:Index:payment,customerNumber: null }
    requirements:
        invoiceNumber: \w+
        _method:  GET

请注意,您可能需要根据您的确切需要更改定义参数的正则表达式.你可以look at this.复数正则表达式必须被“.(示例myvar：”[A-Z] {2,20}“)
