Struct WechatClient 

pub struct WechatClient { /* private fields */ }

WeChat API Client

Reusable HTTP client for calling WeChat APIs. Built with reqwest for async HTTP requests.

Implementations

impl WechatClient

pub fn builder() -> WechatClientBuilder

Create a new client builder

pub fn appid(&self) -> &str

Get the appid

pub fn base_url(&self) -> &str

Get the base URL

pub fn http(&self) -> &Client

Returns the underlying reqwest::Client for raw HTTP requests.

Note: requests made through this client bypass the middleware pipeline. Use get or post for middleware-aware requests.

pub async fn get<T: DeserializeOwned>( &self, path: &str, query: &[(&str, &str)], ) -> Result<T, WechatError>

Make a GET request to WeChat API

Arguments

• path - API endpoint path (e.g., “/cgi-bin/token”)
• query - Query parameters as key-value pairs

Returns

Deserialized response of type T

Errors

• Returns WechatError::Http for non-2xx HTTP status codes or decode failures
• Returns WechatError::Api when WeChat API returns errcode != 0

pub async fn post<T: DeserializeOwned, B: Serialize>( &self, path: &str, body: &B, ) -> Result<T, WechatError>

Make a POST request to WeChat API

Arguments

• path - API endpoint path (e.g., “/wxa/getwxadevinfo”)
• body - Request body to serialize as JSON

Returns

Deserialized response of type T

Errors

• Returns WechatError::Http for non-2xx HTTP status codes or decode failures
• Returns WechatError::Api when WeChat API returns errcode != 0
