网页API的形式，urlen codeD绑定到不同的属性名称 [英] Web API form-urlencoded binding to different property names

问题描述

我期待着与内容类型的POST请求设置为：

I am expecting a POST request with content type set to:

内容类型：应用程序/ x-WWW的形式urlen codeD

Content-Type: application/x-www-form-urlencoded

请求的身体看起来是这样的：

Request body looks like this:

FIRST_NAME =约翰＆安培;姓氏=香蕉

first_name=john&last_name=banana

我的控制器动作有此签名：

My action on controller has this signature:

[HttpPost]
public HttpResponseMessage Save(Actor actor)
{
    ....
}

当演员类给出如下：

Where Actor class is given as:

public class Actor
{
public string FirstName {get;set;}
public string LastName {get;set;}
}

有没有办法来强制网页API绑定：

Is there a way to force Web API to bind:

FIRST_NAME =>姓结果
  姓氏=>姓

first_name => FirstName
last_name => LastName

我知道如何与内容类型的请求设置为application / JSON做，但不能与urlen codeD。

I know how to do it with requests with content type set to application/json, but not with urlencoded.

推荐答案

我98％肯定（我看了源$ C ​​$ c）该的WebAPI不支持它。

I'm 98% certain (I looked the source code) that WebAPI doesn't support it.

如果你真的需要支持不同的属性名称，您可以：

If you really need to support different property names, you can either:

1. 到演员类，它作为别名添加附加属性。

1. Add additional properties to the Actor class which serves as alias.

创建自己的模型粘合剂。

Create your own model binder.

下面是一个简单的模型绑定：

Here is a simple model binder:

public sealed class ActorDtoModelBinder : IModelBinder
{
    public bool BindModel(HttpActionContext actionContext, ModelBindingContext bindingContext)
    {
        var actor = new Actor();

        var firstNameValueResult = bindingContext.ValueProvider.GetValue(CreateFullPropertyName(bindingContext, "First_Name"));
        if(firstNameValueResult != null) {
            actor.FirstName = firstNameValueResult.AttemptedValue;
        }

        var lastNameValueResult = bindingContext.ValueProvider.GetValue(CreateFullPropertyName(bindingContext, "Last_Name"));
        if(lastNameValueResult != null) {
            actor.LastName = lastNameValueResult.AttemptedValue;
        }

        bindingContext.Model = actor;

        bindingContext.ValidationNode.ValidateAllProperties = true;

        return true;
    }

    private string CreateFullPropertyName(ModelBindingContext bindingContext, string propertyName)
    {
        if(string.IsNullOrEmpty(bindingContext.ModelName))
        {
            return propertyName;
        }
        return bindingContext.ModelName + "." + propertyName;
    }
}

如果你准备好迎接挑战，您可以尝试创建一个通用模型绑定。

If you are up for the challenge, you can try to create a generic model binder.
