Kumaraswamy: After the terminal customer authentication function is added to the local application, the developer application uses the three-legged stream OAuth2.0. In this model, taking the previous successful user authentication as an example, the authorization server of the local application contains a short-term access token and a long-term refresh token. The access token provides the API service with access to protected resources. U
With the growing importance of Web API roles, the need to ensure that you can confidently use the Web API in High-value scenarios that can expose sensitive data and operations is becoming more urgent.
We can see clearly that the entire industry is looking for a solution to protect the REST API that relies on the OAuth 2.0 standard. In practice, however, there is

The WordPress Option API is a database storage mechanism provided to developers, which can be quickly and safely stored in a database (both in the Wp_options table) by invoking functions.The pattern for each setting is Key–value, which facilitates expansion. The Option API is not just for themes and plugin developers, but many of the WordPress settings are stored

if our pizzeria has 3 million completed orders, you want to know how many toppings for pepperoni. Sending a GET request to/orders and receiving all 3 million orders will become useless. Fortunately, REST has an excellent way to search for data.
The URLs have a component that we didn't mention, query Sting (Inquiry string). A query refers to the text of a search and a string representation. The query string is some text that goes to the end of a URL, passing information through a URL. For examp
any value unless you specify a constraint. This framework does not match other parts of the URI, such as the host name or a query string. This framework selects the first matched route in the routing table.
There are two special placeholders: "{controller}" and "{action }".
"{Controller}" provides the controller name.
"{Action}" provides the action name. In Web APIs, the Common Convention ignores "{action.
Defaults (default)
If you provide the default value, the route matches the URI that la

Therefore, binding a simple type in the POST request can still use the [FromBody] Feature and is also the most common solution.

The generic error that the package handles includes a debug key that populates the stack trace details when this

The dictionary is stored in the Ihttproutedata object.During the route matching phase, the "{controller}" and "{action}" placeholders are treated like other placeholders. They are simply stored in the dictionary together with other values.For defaults, it can have a special value of routeparameter.opt

Note: When you start Visual Studio for the first time, you must select a predefined setting. Each predefined definition is designed to match different development styles, and determines the form layout, Editor behavior, SMART awareness of code slices, and dialog box options. When the General Development Settings set is used, action descriptions are provided during the experiment to help complete the specified task in Visual Studio. If you select different settings for your development e
plan to re-iterate these steps as needed. Realize that you have more work to do in step 1 (list all the components) by using step 2 (drawing a state diagram). When you're close to writing code (step 6), you might find something missing in the 5th step (creating a semantic file). The key is to use this process to expose as much detail as possible, and be willing to take a step back or two steps to fill in the front missing. Iterations are the
