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

not allowed in certain application scenarios, for example, database clients and database servers are separated by a single firewall, resulting in the inability to use Windows authentication. Applications need to connect to one or more databases using multiple identities. The database you connected to is not SQL Server. There is no secure way to run code in ASP.net as a particular Windows user. In these sce

If you do not set the Web API to return data formatters, browser access to the interface will be different from the browser and different forms of results, because the default header of IE browser is Application/json, so when using IE browser to access the interface, You always need to download the JSON file. Of course you can also modify the return data form on the server.In the Application_Start () meth

access must be enabled on the Web API site. In fact, cors (cross-domain resource sharing) or so-called same origin policy (same-origin policies) is a concept on the browser, and the server needs only to return a few response headers as needed:Access-control-allow-origin: Indicates that the site is allowed access by those sources (domains)Access-control-allow-headers: Indicates that the site allows those cu
