import { wxSdk } from '@nuecms/weapp-sdk';

const sdk = wxSdk({
  appId: string;
  appSecret: string;
  cacheProvider: CacheProvider;
});
```

```typescript
const user = await sdk.getUser({ id: '12345' });
console.log(user);
```

### 4. Signature with API calls
  
```typescript
const sdk = wxSdk({
  appId: string;
  appSecret: string;
  cacheProvider: CacheProvider;
  signature: {
    symKey: string; // 对称密钥
    symSn: string; // 对称密钥编号
    privateSn: string; // 私钥编号
    privateKey: string; // 私钥

## **Usage Examples**

### Registering Endpoints

Register endpoints with their HTTP method, path, and dynamic placeholders (e.g., `{id}`):

```typescript
sdk.r('getUser', '/users/{id}', 'GET');
sdk.r('deleteUser', '/users/{id}', 'DELETE');
sdk.r('createUser', '/users', 'POST');

```

### Making API Calls

Call the registered endpoints dynamically with placeholders and additional options:

```typescript
const userDetails = await sdk.getUser({ id: '12345' });

console.log(userDetails);
```
