我一直在为我公司的网站构建 API。我的所有 GET 都可以正常工作并按照我想要的方式返回 JSON。
不过,在使用 POST 创建新记录时,我遇到了问题。我正在将 JSON 发送到我的控制器。如果我的控制器正在接受字符串或对象参数,这可以正常工作,但在需要模型时不起作用。
在我的 api 控制器中,我有这个方法:
[HttpPost]
public void POSTEstimate(Estimate estimate)
{
//never makes it to the first line when expecting a Model (Estimate)
}
从我一直在阅读的内容来看,Web API 应该能够反序列化自动发布的 JSON(并将其放入我的模型中),但我总是收到 500 内部服务器错误。当我告诉它接受字符串时,该方法工作正常。
有什么明显的我做错了吗?
编辑:这是我用来调用 API 方法的测试页面的堆栈跟踪:
[WebException: The remote server returned an error: (500) Internal Server Error.]
