我的控制器。

public function fedex(){
    $this->load->library('fedex/fedex');
    $fedex = new Fedex; 
    $weight = 46;
    $dest_zip = '10001';
    $fexed_rates = $fedex->rates();
    var_dump($fexed_rates); die;
    }

Answer 1

从最后一行你可以看到

错误行号：$amount = $rateReply->RatedShipmentDetails[0]->ShipmentRateDetail->TotalNetCharge->Amount;

正确： $amount = $rateReply->RatedShipmentDetails->ShipmentRateDetail->TotalNetCharge->Amount;
