How to use the HTTP Client Build builder DSL for Groovy framework in the Java class library

How to use the HTTP Client Build builder DSL for Groovy framework in the Java class library HTTP Client Builder DSL for Groovy is a convenient Java class library that provides a simple and intuitive way to build and send HTTP requests.This article will introduce how to use this framework and provide some Java code examples. 1. Introduce dependencies First, add the dependence of HTTP Client Builder DSL for Groovy to your project.You can add the following dependencies in your project construction file (such as Gradle or Maven): Gradle: implementation 'io.github.bertramn:gretty:1.0.0' implementation 'org.codehaus.gmavenplus.gmavenplus-plugin:1.6.2' Maven: <dependency> <groupId>io.github.bertramn</groupId> <artifactId>gretty</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>org.codehaus.gmavenplus.gmavenplus-plugin</groupId> <artifactId>gmavenplus-plugin</artifactId> <version>1.6.2</version> </dependency> 2. Construct HTTP request To use the HTTP Client Builder DSL for Groovy to send HTTP requests, you need to start building a request from the "HTTP" class.The following are some common construction steps: Create an HTTP instance: def http = new groovyx.net.http.HTTP() Set the requested URL: http = http.request(url: "http://example.com") Set the request method (such as get or post): http = http.get(requestContentType: groovyx.net.http.ContentType.TEXT) Add the request head: http = http.header(name: "Authorization", value: "Bearer TOKEN") Add query parameters: http = http.query(name: "param1", value: "value1") Add a request body: http = http.body("request body") 3. Send HTTP request Once an HTTP request is built, you can use HTTP Client Builder DSL for Groovy.The following is an example of sending GET requests: def response = http.get() Send post request example: def response = http.post() 4. Processing response Once you receive HTTP response, you can use the method provided by HTTP Client Builder DSL for Groovy to process the response.Here are some common methods: Get the status code of the response: response.statusLine.statusCode Get the content of the response: response.entity.content Close response: response.close() This is the basic steps and sample code using the HTTP Client Build Build builder DSL for Groovy in the Java Library.You can adjust and expand according to your needs.I hope this article can help you!
