在 OpenCart 上读取 HttpRequest 发布数据

Question

我正在从 C# windowsform 应用程序向 OpenCart 商店发送 HTTP 请求。

这是 fiddler 显示的我正在发送的内容，看起来是正确的。

这是我正在调用的 OpenCart 项目中的代码。

class ControllerEAOpenCartProducts extends ControllerEAOpenCart {

   public function createProduct()
    {
        print_r($this->request);
    }
}

print_r 正在输出以下数据，这些数据似乎不包含我的任何 JSON 数据。

requst的内容类型也好像不对，不应该像fiddler中的request那样是application/json吗？

看起来 opencart 的请求类包装了 php 的全局变量。这些只有在提交常规表单数据时才会被填充。

要访问json，需要使用较低级别的输入流：

public function createProduct()
{
    print_r(json_decode(file_get_contents('php://input'), true));
}
