How can I use Web APIs to ensure data validity? In actual projects, no data is submitted to meet the requirements. Besides, there are more than N keywords in tianchao. Therefore, the following content adds web API data verification.Step 1 modify the Object Model Public Class Userinfo{ Public Int Id { Get ; Set ;}[Required][Stringlength ( 20 , Errormessage = "

Now we'll turn to the client side, and add a page that can consume data from the Admin controller. the page will allow users to create, edit, or delete products, by sending AJAX requests to the controller. Now we are transferring to the client and adding a page that can use data from the Admin controller. By sending an AJAX request to the Controller, this page allows users to create, edit, or delete products. In Solution Explorer, expand the Controllers folder and open the file named HomeControl

indicates the cache of short-time resources (memory cache), while the strong type of ETag cache is implemented through persistence. First, create a picture: After a brief introduction, we can implement the so-called "conditional request ". We need to use NuGet to install CacheCow, open the NuGet console, and enter"Install-Package CacheCow. Server-Version 0.4.12". Two dll files, CacheCow. Server and CacheCow. Common, are installed. Configuring CacheCow is also very simple. What we need t

paging metadata contains the data totalCount, totalPages, prevPageLink, and nextPageLink. It is very useful for the client to return the data totalCount and totalPages, in this way, you can bind the results with some grids. Generally, we encapsulate paging metadata in the response Body. for developers, we provide all paging information. However, some API consumers only want to obtain the requested data without paging metadata. Therefore, it will be

method receives a parameter Id, and the Id should be set in the URL, so the content of the request body is empty. 3. If the deletion is successful, we will return the 200 status code. If the deletion fails, 400 (BadRequest) will be returned, and the error content will also be returned to the client. OK. Let's test: Send A Delete request (Http: // localhost: {your_port}/api/courses/1003) The request section is shown in: StudentController is used to i

However, with the help of the Project Background of the original series, the external series is named, some new technologies may be added to this series in the future. In Web Api 2.0, A New Route configuration method is proposed-Attribute-based

The configuration is related to the OAuth Protocol. To understand the OAuth protocol, you must understand the http get/POST method. Therefore, we have studied how to use Web APIs or MVC to construct POST messages and implement interaction between the client and the server. The tool I used is Visual Studio 2013 + Web API 2 + MVC 5. Create two

1. Brief Introduction to HttpClientI vaguely remember that at that time, I used WebClient and HttpWebRequest to send a request. Now ASP. NET MVC4 comes with a class HttpClient, which is used to receive HttpResponseMessage and send HttpRequestMesssage. The problem is that since WebClient and HttpWebRequest can complete the corresponding functions, why should we use the HttpClient class ,. since such a class

By default, WEB APIs use the request sent by the browser Header of the client to determine the returned format, as shown in red. The browser uses XML by default. Therefore, if we do not limit the Accept value of the Header, XML is returned by default. The data formats returned by the wen api server mainly include XML and JSON. Our idea is to directly remove the XML format from the server, so naturally we ha
