如何使用PHP curl方法格式化POST请求？

Question

我试图发送带有此有效负载的post请求：

$request_content = [
    "data" => [
        [
            "sku" => "0987",
            "price" => $price,
            "category" => "moveis",
            "brand" => "bartira",
            "zip_code" => "07400000",
            "affiliate" => "google-shopping"
        ]
    ]
];

因为这是一篇文章，所以我将CURLOPT_POST设置为true；

$encoded_request = json_encode($request_content);
$ch = curl_init("https://my-service/endpoint/");
curl_setopt($ch, CURLOPT_HTTPHEADER, ["Authorization: Token my-token"]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $encoded_request);

在$encoded_request中显示的print_r内容是：

{
"data": [
    {
        "sku": "0987",
        "price": "5.99",
        "category": "moveis",
        "brand": "bartira",
        "zip_code": "07400000",
        "affiliate": "google-shopping"
    }
]
}

如果我在Postman上使用这个内容，我会从我请求的服务中得到正确的响应，但是在我的代码中我得到了错误；

{“数据”：“此字段是必需的。”}

我在curl_上缺少哪种配置来正确格式化有效负载？

您可以尝试设置CURLOPT_HTTPHEADER并更改变量$request_content，如下所示：

//set your data
$request_content = [
    "data" => [
        "sku" => "0987",
        "price" => $price,
        "category" => "moveis",
        "brand" => "bartira",
        "zip_code" => "07400000",
        "affiliate" => "google-shopping"
    ]
];
$encoded_request = json_encode($request_content);

$ch = curl_init("https://my-service/endpoint/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $encoded_request);

// Set HTTP Header for POST request 
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Authorization: Token my-token',
    'Content-Type: application/json',
    'Content-Length: ' . strlen($encoded_request)]
);
