General Consistent Return Model

Change the return type of your API controller to MessageModel<T>, where T is the type of data you are returning. For example:

[HttpGet]
public MessageModel<string> Get()
{
	return new MessageModel<string>
	{
		Status = 0,
		Msg = "Success",
		Data = "Hello, World!"
	};
}

Add filters for unhandled exceptions and model validation failures:

builder.Services.AddUnhandledExceptionFilter(config =>
{
    config.Status = 500;
    config.StatusCode = 500;
    config.WithTraceId = false; //Whether to return TraceId
    config.Message = "Unhandled Exception";
});

Add a filter for model validation failure:

builder.Services.AddModelValidationExceptionFilter(config =>
{
	config.Status = 400; //Business status code
	config.StatusCode = 400; //HTTP status code
    config.Message = "Model Validation Exception"; //Custom message
});

Generating HTML Message Pages

To generate HTML message pages, you can use the MessagePage class. This class provides some properties for setting the content of the page, and then you can call the Render method to generate the HTML page.

The page UI adopts WeUI version 2.5.11, styled after WeChat official accounts, including title, icon, content, list, links, buttons, and footer links.

public ContentResult Page()
{
    var page = new MessagePage
    {
        Icon = MsgIcon.Safe_Warn,
        HtmlTitle = "Webpage Title",
        Title = "Message Title",
        Desc = "Detail content, can be arranged according to actual needs. If it wraps, it should not exceed the specified length and should be centered [hyperlink support](http://www.baidu.com)",
        DescInfo = "Detail content, can be arranged according to actual needs. If it wraps, it should not exceed the specified length and should be centered",
        Custom = "<textarea>Custom html area</textarea>",
        ListInfo = new List<string> { "List hint item", "List hint item", "List hint item" },
        KeyValues = new Dictionary<string, string> { { "Name", "Zhang San" }, { "WeChat ID", "123" } },
        ListUrl = new List<UrlInfo> { new("Link 1", "javascript:"), new("Link 2", "javascript:") },
        TipsPre = "Detail content, can be arranged according to actual needs. If it wraps, it should not exceed the specified length and should be centered [hyperlink support](http://www.baidu.com)",
        TipsNext = "Detail content, can be arranged according to actual needs. If it wraps, it should not exceed the specified length and should be centered [hyperlink support](http://www.baidu.com)",
        OprBtn = new List<UrlInfo> { new("Link 1", "javascript:"), new ("Link 2", "javascript:", "default") },
        FooterLink = new UrlInfo("Footer Link", "javascript:"),
        CopyRight = "Sang Late Autumn Copyright Information<br>© 2014-2021 Sang. All Rights Reserved."
    };
    return new ContentResult
    {
        ContentType = "text/html",
        StatusCode = 200,
        Content = page.Render()
    };
}
