ASP.NET Web Api中的自定义参数BindingAttribute

如何实现自定义

参数bindingAttribute

类似

[FromBody]

// POST api/<controller>
public void Post([FromBody]string value)
{
}

通过创建自定义

BinderType

public string Get([FromUri(BinderType = typeof(UrlToFileSystemMapping))]string path = "")
{              

}

public class UrlToFileSystemMapping : IModelBinder
{
    bool IModelBinder.BindModel(HttpActionContext actionContext, ModelBindingContext bindingContext)
    {
        var val = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
        if (val != null)
        {
            var s = val.AttemptedValue as string;
            if (s != null)
            {
                bindingContext.Model = s.Replace('|', '\\');    
                return true;
            }
        }
        return false;
    }
}

public string Get([FromUri(BinderType = typeof(UrlToFileSystemMapping))]string path = "")
{              

}

public class UrlToFileSystemMapping : IModelBinder
{
    bool IModelBinder.BindModel(HttpActionContext actionContext, ModelBindingContext bindingContext)
    {
        var val = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
        if (val != null)
        {
            var s = val.AttemptedValue as string;
            if (s != null)
            {
                bindingContext.Model = s.Replace('|', '\\');    
                return true;
            }
        }
        return false;
    }
}
