Go by Example

# HTTP Client This program demonstrates making an HTTP GET request to the "" website and printing the first five lines of the response body. Here's a breakdown of the code: ```go package main import ( "bufio" "fmt" "net/http" ) func main() { // Make an HTTP GET request resp, err := http.Get("https://gobyexample.com") if err != nil { panic(err) } defer resp.Body.Close() // Print the response status fmt.Println("Response status:", resp.Status) // Use a scanner to read the response body line by line scanner := bufio.NewScanner(resp.Body) for i := 0; scanner.Scan() && i < 5; i++ { // Print the first five lines of the response body fmt.Println(scanner.Text()) } // Check for any errors that occurred during scanning if err := scanner.Err(); err != nil { panic(err) } } ``` #### Output ``` Response status: 200 OK Go by Example ``` Explanation: 1. The `http.Get` function is used to make an HTTP GET request to the specified URL (""). The response and any error are checked. 2. The `defer` statement ensures that the response body is closed when the function exits. 3. The response status is printed to the console. 4. A `bufio.Scanner` is created to read the response body line by line. 5. A loop is used to read and print the first five lines of the response body. 6. Any errors that occurred during scanning are checked and handled. You can run the program to see the response status and the first five lines of the HTML content from "". --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://ineelhere.gitbook.io/code-with-go/74-http-client.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
