如何把select选项从URL里 传给后端

Question

前端是一个select 选项 URL里面就带有qurystrings
但是用axios 写get请求的 后端取不到qurey strings
这是前端的代码

class App extends Component {

handleSend=()=>{

axios.get('/api'
 )

}
render() {

return (
  <div>
   Hallo world
   <form>
    <select 
      name = 'issuer'>
    <option value='ideal_ABNANL2A'>ABN AMRO</option>
    <option value='ideal_ASNBNL21'>ASN Bank</option>
    <option value='ideal_BUNQNL2A'>bunq</option>
    <option value='ideal_INGBNL2A'>ING</option>
    <option value='ideal_KNABNL2H'>Knab</option>
    <option value='ideal_MOYONL21'>Moneyou</option>
    <option value='ideal_RABONL2U'>Rabobank</option>
    <option value='ideal_RBRBNL21'>RegioBank</option>
    
    </select>
    <button onClick={this.handleSend}>Select issuer</button>
    </form> 
      
  </div>
  
);

}
}
