Struct CdnClient 

pub struct CdnClient { /* private fields */ }

HTTP client for WeChat CDN media endpoints.

Cheap to Clone — shares the underlying reqwest::Client, which uses an Arc internally.

Example

use wechat_ilink::{CdnClient, CDNMedia};

let cdn = CdnClient::new();
let bytes = cdn.download(&media, None).await?;

Implementations

impl CdnClient

pub fn new() -> Self

Create a CdnClient with a fresh internal reqwest::Client.

pub fn with_client(http: Client) -> Self

Create a CdnClient that reuses an existing reqwest::Client.

Useful when the caller already maintains a shared HTTP client with custom proxy / TLS / timeout configuration.

pub fn with_base_url(self, base_url: impl Into<String>) -> Self

Override the CDN base URL (defaults to CDN_BASE_URL).

Primarily intended for tests and regional endpoints.

pub async fn download( &self, media: &CDNMedia, aes_key_override: Option<&str>, ) -> Result<Vec<u8>>

Download and AES-decrypt a CDN media object.

aes_key_override is used when the decryption key is attached to the message metadata (e.g. ImageContent::aes_key) rather than embedded in the media’s own aes_key field.
