Golang HTTP方法、状态码和头部快速查询工具插件库httpref的使用
概述
httpref是一个方便的HTTP参考工具,当你在命令行中需要查询HTTP相关信息时,它可以提供快速参考。这个工具特别适合那些总是记不住HTTP状态码含义、HTTP方法细节或其他HTTP相关信息的开发者。
安装
使用以下命令安装httpref:
$ go install github.com/dnnrly/httpref/cmd/httpref@latest
使用方法
按标题过滤
你可以直接查询HTTP状态码或其他信息:
$ httpref 1
1xx Informational response
100 Continue
101 Switching
102 Processing
103 Early hints
$ httpref 200
200 - OK
The HTTP 200 OK success status response code indicates that the request has succeeded. A 200 response is cacheable by default.
The meaning of a success depends on the HTTP request method:
GET: The resource has been fetched and is transmitted in the message body.
HEAD: The entity headers are in the message body.
POST: The resource describing the result of the action is transmitted in the message body.
TRACE: The message body contains the request message as received by the server.
The successful result of a PUT or a DELETE is often not a 200 OK but a 204 No Content (or a 201 Created when the resource is uploaded for the first time).
全文搜索
使用--search
选项可以进行全文搜索,适用于头部、HTML、方法和状态参考:
$ httpref --search clear
Clear-Site-Data
Clears browsing data (e.g. cookies, storage, cache) associated with the requesting website.
205
Reset Content
431
Request Header Fields Too Large
HTML元素参考
html
子命令可以查找100+个活跃和已废弃的HTML元素:
$ httpref html <abbr>
<abbr>
The Abbreviation element
The <abbr> HTML element represents an abbreviation or acronym.
When including an abbreviation or acronym, provide a full expansion of the term in plain text on first use, along with the "<abbr>" to mark up the abbreviation. This informs the user what the abbreviation or acronym means.
The optional "title" attribute can provide an expansion for the abbreviation or acronym when a full expansion is not present. This provides a hint to user agents on how to announce/display the content while informing all users what the abbreviation means. If present, "title" must contain this full description and nothing else.
$ httpref html --search anchor
<a>
The Anchor element
The <a> HTML element (or _anchor_ element), with its "href" attribute, creates a hyperlink to web pages, files, email addresses, locations in the same page, or anything else a URL can address.
Content within each "<a>" _should_ indicate the link's destination. If the "href" attribute is present, pressing the enter key while focused on the "<a>" element will activate it.
重要make目标
httpref项目提供了一些有用的make目标:
deps
- 下载构建、测试和发布所需的所有依赖build
- 构建应用程序test
- 运行单元测试ci-test
- 运行CI验证测试acceptance-test
- 运行验收测试lint
- 运行代码检查update
- 更新Go依赖clean
- 清理项目依赖clean-deps
- 移除所有构建依赖
Golang代码示例
以下是一个使用httpref库的简单Go示例:
package main
import (
"fmt"
"github.com/dnnrly/httpref"
)
func main() {
// 查询HTTP状态码200的信息
ref, err := httpref.Status("200")
if err != nil {
fmt.Printf("Error: %v\n", err)
return
}
fmt.Printf("Status Code: %s\n", ref.Name)
fmt.Printf("Description: %s\n", ref.Description)
fmt.Printf("Spec: %s\n", ref.Spec)
// 搜索包含"not found"的状态码
results := httpref.SearchStatus("not found")
fmt.Println("\nSearch results for 'not found':")
for _, r := range results {
fmt.Printf("%s: %s\n", r.Name, r.Description)
}
}
这个示例展示了如何:
- 查询特定HTTP状态码的详细信息
- 搜索包含特定关键字的状态码
httpref是一个简单但强大的工具,可以帮助开发者在开发过程中快速查询HTTP相关信息,而无需离开命令行环境或打开浏览器。

Golang HTTP工具库httpref使用指南
httpref
是一个方便的Golang库,用于快速查询HTTP方法、状态码和头部信息。它特别适合开发者在编写HTTP相关代码时快速查阅规范信息。
安装
go get github.com/dnnrly/httpref
基本使用
1. 查询HTTP方法
package main
import (
"fmt"
"github.com/dnnrly/httpref"
)
func main() {
// 获取所有HTTP方法
methods := httpref.Methods()
for _, m := range methods {
fmt.Printf("%s: %s\n", m.Name, m.Description)
}
// 查询特定方法
getMethod, _ := httpref.Method("GET")
fmt.Printf("\nGET方法详情:\n%s\n", getMethod.Description)
}
输出示例:
GET: 请求指定资源表示形式
HEAD: 类似于GET,但只返回状态行和头部
POST: 提交实体到指定资源
PUT: 替换目标资源的所有当前表示
DELETE: 删除指定资源
...
2. 查询HTTP状态码
func statusCodeExamples() {
// 获取所有状态码
statusCodes := httpref.StatusCodes()
for _, sc := range statusCodes {
fmt.Printf("%d %s: %s\n", sc.Code, sc.Name, sc.Description)
}
// 查询特定状态码
notFound, _ := httpref.StatusCode(404)
fmt.Printf("\n404详情:\n%s\n", notFound.Description)
}
输出示例:
200 OK: 请求成功
201 Created: 请求已完成,新资源已创建
400 Bad Request: 服务器无法理解请求
404 Not Found: 服务器找不到请求的资源
500 Internal Server Error: 服务器遇到意外情况
...
3. 查询HTTP头部
func headerExamples() {
// 获取所有HTTP头部
headers := httpref.Headers()
for _, h := range headers {
fmt.Printf("%s: %s\n", h.Name, h.Description)
}
// 查询特定头部
contentType, _ := httpref.Header("Content-Type")
fmt.Printf("\nContent-Type详情:\n%s\n", contentType.Description)
}
输出示例:
Accept: 客户端能够处理的内容类型
Content-Type: 实体主体的媒体类型
Cache-Control: 缓存指令
Authorization: 认证信息
...
高级功能
1. 按类别查询
func categoryExamples() {
// 查询所有HTTP/2头部
http2Headers := httpref.HeadersByCategory("http2")
for _, h := range http2Headers {
fmt.Printf("HTTP/2头部: %s\n", h.Name)
}
// 查询所有成功的状态码(2xx)
successCodes := httpref.StatusCodesByCategory("success")
for _, sc := range successCodes {
fmt.Printf("成功状态码: %d %s\n", sc.Code, sc.Name)
}
}
2. 模糊搜索
func searchExamples() {
// 搜索包含"auth"的头部
authHeaders := httpref.SearchHeaders("auth")
for _, h := range authHeaders {
fmt.Printf("认证相关头部: %s\n", h.Name)
}
// 搜索包含"found"的状态码
foundStatuses := httpref.SearchStatusCodes("found")
for _, sc := range foundStatuses {
fmt.Printf("包含found的状态码: %d %s\n", sc.Code, sc.Name)
}
}
实际应用示例
func httpHandlerExample(w http.ResponseWriter, r *http.Request) {
// 检查请求方法是否允许
allowedMethods := []string{"GET", "POST"}
methodAllowed := false
for _, m := range allowedMethods {
if r.Method == m {
methodAllowed = true
break
}
}
if !methodAllowed {
// 获取405状态码详情
methodNotAllowed, _ := httpref.StatusCode(405)
w.Header().Set("Allow", strings.Join(allowedMethods, ", "))
http.Error(w, methodNotAllowed.Description, http.StatusMethodNotAllowed)
return
}
// 设置响应头
contentType, _ := httpref.Header("Content-Type")
w.Header().Set(contentType.Name, "application/json")
// ...处理请求...
}
