impl User

Source

pub async fn login(&self, code: &str) -> Result<Credential>

用户登录凭证校验

通过微信前端获取的临时登录凭证 code,换取用户的唯一标识 OpenID 和会话密钥。

§参数
  • code: 微信前端通过 wx.login() 获取的临时登录凭证
§返回

成功返回 Ok(Credential),包含用户身份信息

§错误
  • 网络错误
  • 微信 API 返回错误
  • 响应解析错误
§示例
use wechat_minapp::client::WechatMinappSDK;
use wechat_minapp::user::{User, Contact};

 #[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = WechatMinappSDK::new("app_id", "secret");
    let user = User::new(client);
    let code = "0816abc123def456";
    let credential = user.login(code).await?;
    println!("用户OpenID: {}", credential.open_id());
    println!("会话密钥: {}", credential.session_key());
     
    Ok(())
}

微信官方文档 - code2Session

Source

pub async fn get_contact( &self, code: &str, open_id: Option<&str>, ) -> Result<Contact>

获取用户手机号信息

通过前端获取的临时凭证 code 换取用户的手机号信息。

§参数
  • code: 前端通过 wx.getPhoneNumber 获取的临时凭证
  • open_id: 用户 OpenID(可选),如果提供可以提升安全性
§返回

成功返回 Ok(Contact),包含用户手机号信息

§错误
  • 网络错误
  • 微信 API 返回错误
  • 访问令牌无效或过期
§示例
use wechat_minapp::client::WechatMinappSDK;
use wechat_minapp::user::{User, Contact};

 #[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = WechatMinappSDK::new("app_id", "secret");
    let user = User::new(client);
    let code = "0816abc123def456";
    let contact = user.get_contact(code, None).await?;
    println!("用户手机号: {}", contact.phone_number());
     
    Ok(())
}
§前端配合

前端需要调用 wx.getPhoneNumber 获取临时凭证:

wx.getPhoneNumber({
  success: (res) => {
    console.log(res.code); // 将这个 code 发送到后端
  },
  fail: (err) => {
    console.error(err);
  }
});
