excerpt:
Abstract: This article describes the useRequestURL combinatorial function in Nuxt 3 for obtaining URL information about the current page in both server-side and client-side environments. Examples show how to use this function to get and display the URL and its components, such as path, query parameters, etc., in a page for modern web application development.

Getting and manipulating URLs is an integral part of building modern web applications.Nuxt 3 provides a powerful tool - theuseRequestURLCombination function which allows us to get the URL information of the current page in both server-side and client-side environments.

useRequestURLusage

useRequestURLis a helper function that returns an object containing the full URL information for the current page. This function is very useful in Nuxt 3 because it provides a uniform way to access URL information, both in a server-side rendering and a client-side rendering environment.

usage example

Let's say you're developing a Nuxt 3 project, and thepages/page where you want to get the URL information of the current page. Here's how to use theuseRequestURLto achieve this goal:

  1. utilizationuseRequestURL：

    existpages/(used form a nominal expression)setupfunction, calling theuseRequestURLto get information about the URL of the current page. This returns an object containing the raw string of the URL, query parameters, path, hash value, and other information.

    <script>

export default {
  setup() {
    // Use useRequestURL to get the URL of the current page.
    const url = useRequestURL();

    // Returns an object containing the URL and path information.
    return {
      url
    }; }
  }
}; }
}; }; </script>

  2. Display URL and path information：

    In the template section, you can use the{{ url }}to display the full URL information, use the{{ }}to display path information.

    <template>
  <div>
    <p>URL is: {{ url }}</p>
    <p> path is: {{ }}</p>
  </div>
</template>

Run your project in the development environment and access the/aboutPage. In your browser's developer tools, you should see the following output:

The URL is: /about
The path is: /about

this suggests thatuseRequestURLSuccessfully got the URL information for the current page and displayed the URL and path correctly in the template.

causality

The following is a detailed explanation of several key properties in the URL object:

1. hash

hash attribute is an attribute that contains the#(used form a nominal expression)USVString(Uniform Shared Value String) followed by the fragment identifier of the URL. For example, in the URL/path#sectionMiddle.hashattribute will contain the#section。

2. host

host attribute is aUSVString, contains the domain name portion of the URL, followed by a colon and port number if a port is specified. For example, in the URL:8080/pathMiddle.hostattribute will contain the:8080。

3. hostname

hostname attribute is a URL containing the domain name of theUSVString. For example, in the URL/pathMiddle.hostnameattribute will contain the。

4. href

href attribute is a URL containing the fullUSVString. For example, in the URL/pathMiddle.hrefattribute will contain the/path。

5. origin

origin attribute returns a protocol name, domain name, and port number with theUSVString. For example, in the URL/pathMiddle.originattribute will contain the。

6. password

password attribute contains the password specified in front of the domain name of theUSVString. For example, in the URLhttps://user:password@/pathMiddle.passwordattribute will contain thepassword。

7. pathname

pathname attribute is an attribute that starts with/beginningDOMStringthat immediately follows the file path portion of the URL. For example, in the URL/path/to/Middle.pathnameattribute will contain the/path/to/。

8. port

port attribute containing the port number of the URL'sUSVString. For example, in the URL:8080/pathMiddle.portattribute will contain the8080。

9. protocol

protocol attribute contains the URL protocol name of theUSVString, ending with a colon. For example, in the URL/pathMiddle.protocolattribute will contain thehttps:。

10. search

search attribute is an attribute that contains theUSVString(used form a nominal expression)USVString, a string of parameters indicating the URL. If any parameters are supplied, this string includes all parameters and begins with a question mark. For example, in the URL/path?param1=value1&param2=value2Middle.searchattribute will contain the?param1=value1&param2=value2。

11. searchParams

searchParams attribute is aURLSearchParamsobject that can be used to access thesearchThe individual query parameters found in the For example, you can use it to get the value of a URL parameter or to modify a parameter.
