antd3.20.0版本的AutoComplete组件当value相同的时候报错react same key

目前的需求是需要用到antd的AutoComplete组件,来做一个输入的时候调高德地图的api检索address数据,但是问题是address数据会重复,name跟value都会重复,然后AutoComplete组件就会报错,我这边,key是唯一的,使用的是id,但是很奇怪就是一直报same key的错。

代码:

                        <AutoComplete
                          style={{ width: 150 }}
                          placeholder=""
                          value={rule.address || ''}
                          onSearch={this.queryMapLocations}
                          onSelect={this.selectMapLocation}
                          onChange={e => actions.handleChange(e, rule.key, 'address')}
                          optionLabelProp="value"
                          allowClear
                        >
                          {
                            autoCompleteOptions
                          }
                        </AutoComplete>
                        
                        
                        
                        
queryMapLocations = async (queryString) => {
    const result = await this.mapContainer.search(queryString);
    const options = result && result.pois
      ? result.pois.map(item => (
        <Option key={item.id} value={item.address}>{item.address}</Option>
      ))
      : [DefaultOption];
    // const oriResult = result && result.pois
    //   ? result.pois.map(item => ({
    //     value: item.address,
    //     ...item
    //   }))
    //   : [];
    this.setState({ autoCompleteOptions: options }, () => {});
  }

报错:

Warning: Encountered two children with the same key, `.$G111(京加路)附近`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.

    emmmm好了,自己解决了,问问题10分钟,解决只要1分钟。哭了😭
    解决方案:
    optionLabelProp="label"自定义一个label属性,用来回显,这样的话,value是唯一的了。

    <Option key={item.id} value={item.id} label={item.address}>{item.address}</Option>
