七牛认证信息

负责存储调用七牛 API 所必要的认证信息，提供 CredentialProvider 方便扩展获取认证信息的方式。同时提供阻塞接口和异步接口（异步接口需要启用 async 功能）。提供 CredentialProvider 的多个实现方式，例如：

GlobalCredentialProvider : 使用全局变量配置的认证信息
EnvCredentialProvider : 使用环境变量配置的认证信息
ChainCredentialsProvider : 配置多个 CredentialProvider 形成认证信息串，遍历找寻第一个可用的认证信息

代码示例

计算七牛鉴权签名 V1

use qiniu_credential::{Credential, HeaderValue, prelude::*};
use mime::APPLICATION_WWW_FORM_URLENCODED;
use std::io::Cursor;

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let authorization = credential
    .get(Default::default())?
    .authorization_v1_for_request(
        &"http://upload.qiniup.com/".parse()?,
        Some(&HeaderValue::from_str(APPLICATION_WWW_FORM_URLENCODED.as_ref())?),
        b"name=test&language=go"
    );

计算七牛鉴权签名 V2

use qiniu_credential::{Credential, Method, HeaderMap, HeaderValue, prelude::*};
use http::header::CONTENT_TYPE;
use mime::APPLICATION_JSON;
let credential = Credential::new("abcdefghklmnopq", "1234567890");
let mut headers = HeaderMap::new();
headers.insert(CONTENT_TYPE, HeaderValue::from_str(APPLICATION_JSON.as_ref())?);
let authorization = credential
    .get(Default::default())?
    .authorization_v2_for_request(
        &Method::GET,
        &"http://upload.qiniup.com/".parse()?,
        &headers,
        b"{\"name\":\"test\"}".as_slice(),
    );

计算下载地址签名

use qiniu_credential::{Credential, prelude::*};
use std::time::Duration;
let credential = Credential::new("abcdefghklmnopq", "1234567890");
let url = "http://www.qiniu.com/?go=1".parse()?;
let url = credential
    .get(Default::default())?
    .sign_download_url(url, Duration::from_secs(3600));
println!("{}", url);
Ok(())
