假设您有一种使用单选按钮和标准“提交”按钮提交的表单。我希望能够不使用网站而是使用cURL从命令行提交对表单的回复。
当我在浏览器中提交表单并检查网络流量时，以下是我看到的重要详细信息：
URL（示例）：www.example.com/folder/ajax.php
数据：{JSON内容的大字符串}
这是我正在尝试的curl调用：
curl -X POST -H "Content-Type: application/json" -L -d '{big string of json stuff}' http://www.example.com/folder/ajax.php --verbose
我遇到的问题是我的请求实际上没有做任何事情，也就是说，提交表单后，我没有看到期望的网站上的更改。帮助吗？
编辑：我可以看到我的请求失败。成功的呼叫将返回类似下面的行的内容，该行不会出现。所以问题是我的电话怎么了？
{"success":true,"data":{website specific stuff}}
以下是我打电话时得到的信息：
