Expand description

HTTP 请求构建器 (Fluent API)

使用流式 API 构建完整的 HTTP 请求,自动添加标准 headers。

§Examples

use url::Url;
use aria2_core::http::request_response::{HttpRequestBuilder, HttpMethod};

let url = Url::parse("http://example.com/api").unwrap();
let request = HttpRequestBuilder::new(HttpMethod::Get, url)
    .header("Accept", "application/json")
    .build()
    .unwrap();

Implementations§

Source§

impl HttpRequestBuilder

Source

pub fn new(method: HttpMethod, url: Url) -> Self

创建新的 HTTP 请求构建器

§Arguments
  • method - HTTP 请求方法 (GET/POST/HEAD/PUT/DELETE)
  • url - 目标 URL
§Returns

新的 HttpRequestBuilder 实例

Source

pub fn header(self, key: &str, value: &str) -> Self

添加单个 header

如果已存在相同 key 的 header,将被覆盖。

§Arguments
  • key - header 名称
  • value - header 值
§Returns

Self,支持链式调用

Source

pub fn headers(self, headers: HashMap<String, String>) -> Self

批量设置 headers

将传入的所有 headers 合并到现有 headers 中。 如果存在重复 key,新值会覆盖旧值。

§Arguments
  • headers - 要添加的 headers 集合
§Returns

Self,支持链式调用

Source

pub fn body(self, body: Vec<u8>) -> Self

设置请求体

§Arguments
  • body - 请求体的字节数据
§Returns

Self,支持链式调用

Source

pub fn build(self) -> Result<HttpRequest>

构建最终的 HTTP 请求

自动添加以下标准 headers:

  • Host: 从 URL 中提取
  • User-Agent: aria2-rust/1.0
  • Accept: /
  • Connection: close
  • Content-Length: 如果有 body
§Returns

构建完成的 HttpRequest,或错误信息
