如何在 php 中使用 JSON 发送 POST 请求？

Question

我尝试将请求从帖子类型发送到服务器，但没有成功，它返回状态为 400 的 BadRequest，

我的代码：

<?php

$products = array('1'=>array('amount'=>'1','product_id'=>'11250'));
$data = array('id' => '67', 'shipping' => '61', 'payment'=> '2','products'=> $products);
$cert = base64_encode('myapp@myapp.co.il:1234abcd');
$url = "https://myapp.co.il/api/aaa";


$ch = curl_init($url);
$payload = json_encode($data);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "authorization: Basic ".$cert,
    "Content-Type: application/json",
    "cache-control: no-cache"
    ));
$result = curl_exec($ch);
curl_close($ch);
var_dump($result);

?> 

它让我回复：

数组 (2) {["message"] => 字符串 (51) "错误请求：语法错误，JSON 失真" ["status"] => int (400)}

我看到您准备$payload要发送的变量$payload ，但在curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata)处发送了$postdata 。
