当我在{ "status": 400,"statusText": "Value cannot be . (Parameter 'uriString')","item":,"itemCount": 0,"skipCount": 0,"requestDate": "2020-09-10T02:09:37.2912502-07:00","responseDate": "2020-09-10T02:09:37.2933547-07:00" },undefined 正文中发布https://umuly.com/api/url时

我收到此消息：

<div className="filter_role">Role{" "}<select 
                    defaultValue={this.state.role}
                    onChange={this.filterRole.bind(this)}
                    >
                    <option value="">All</option>
                    <option value="Batsman">Batsman</option>
                    <option value="Wk-Batsman">WK-Batsman</option>

                    </select>
 </div> 


 filterRole = (event) => {

    if(event.target.value === "") {
        this.setState({role:event.target.value,players: this.state.players})
    } else {
        this.setState({
            role: event.target.value,players: this.state.players.filter(player => player.role.indexOf(event.target.value)>=0)
        })
    }
    console.log(event.target.value)
}
