我如何在此回复中获得费用的价值

我正在将邮递员 api 集成到 php 应用程序中，因为我正在使用来自 php 的 curl 调用，

这是代码

<?php

class PostMates extends Controller {

public function getDeliveryQuote()
    {
            $url = "https://api.postmates.com/v1/customers/cus_XX/delivery_quotes";

    $uname = "70538e7";
    $pwd = "xxxx";

    $process = curl_init($url);
    curl_setopt($process, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded','Accept: application/json'));
    curl_setopt($process, CURLOPT_HEADER, 1);
    curl_setopt($process, CURLOPT_USERPWD, $uname . ":" . $pwd);
    curl_setopt($process, CURLOPT_TIMEOUT, 30);
    curl_setopt($process, CURLOPT_POST, 1);
    curl_setopt($process, CURLOPT_POSTFIELDS, "dropoff_address=20 McAllister St, San Francisco, CA 94102&pickup_address=101 Market St, San Francisco, CA 94105");
    curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($process, CURLOPT_SSL_VERIFYPEER, false);
    $return = curl_exec($process);

    curl_close($process);

    //var_dump($return);
    print_r($return);


    }

}

当我做 print_r 和 var_dump 时，下面给出的是响应。

给你。您必须解析结果。

$result = json_decode($result,true); //decodes JSON to associative array

echo $result['fee']; //750

或者，如果您想使用对象格式

$result = json_decode($result); //decodes JSON to an object

echo $result->fee; //750

编辑

您还需要设置CURLOPT_HEADER为false

这包括输出中的响应标头

curl_setopt($process, CURLOPT_HEADER, false);
