Struct QrCode 

pub struct QrCode {
    pub buffer: Vec<u8>,
}

二维码图片数据

包含生成的二维码图片的二进制数据，通常是 PNG 格式。

示例

use wechat_minapp::client::WechatMinappSDK;
use wechat_minapp::qr::{QrCodeArgs,Qr, MinappEnvVersion};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // 初始化客户端
    let app_id = "your_app_id";
    let secret = "your_app_secret";
    let client = WechatMinappSDK::new(app_id, secret);
    let qr = Qr::new(client);

    let args = QrCodeArgs::builder()
    .path("pages/index/index")
    .build()
    .unwrap();
    // 生成小程序码
    let qr_code = qr.qr_code(args).await?;
     
    // 获取小程序码图片数据
    let buffer = qr_code.buffer();
    Ok(())
}

Fields

buffer: Vec<u8>
