如何验证JSON对象? [英] How to validate JSON object?

问题描述

我想在服务器端验证传入的json对象的正确性.有没有标准/最佳的方法来做到这一点?您的验证方式是什么?

I would like to validate incoming json object for correctness at the server side. Is there a standard / optimal way to do that? What is your approach of validation?

推荐答案

我的建议-反序列化JSON，看看它是否损坏.例如，如果您在服务器端使用C#，则可以使用新的DataContractJsonSerializer，也可以使用JavaScriptSerializer进行旧的操作，这可能会简单得多.

My advice - deserialize the JSON and see if it breaks. For example, if you're using C# on the server side, you can use the newfangled DataContractJsonSerializer, or do it the old way with the JavaScriptSerializer which is arguably much simpler.

var serializer = new JavaScriptSerializer();
var result = serializer.Deserialize<Dictionary<string, object>>(jsonString);

现在，事实证明您正在使用Java，当然我的C#示例对您不起作用，但是概念是相同的. Stackoverflow已在此处中提供了一些答案:

And now that it's come out that you're using Java, of course my C# example is not going to work for you, but the concept is the same. Stackoverflow already has some answers here: Convert a JSON string to object in Java ME?
