一，前言
因业务需要，系统需要实现行驶证识别功能。本着节约时间成本，循序渐进的原则，该功能直接调用阿里的相关接口，现将调试过程记录在下。
二，正文
1，接口地址：
2，在线调试：
3，接下来就是把这项功能移动到项目当中去
（1）antd+react前端上传照片：
组件初始化
class VehicleLicenseTab extends Component {
state = {
previewVisible: false,
previewImage: '',
positiveList:[],
contraryList:[],
workId: null,
positivePhoto:null,//正面照片
contraryPhoto:null,//反面照片
positiveWordsState:false,//正面照片置空标识
contraryWordsState:false,//反面照片置空标识
};操作函数：
handleCancel = () => this.setState({ previewVisible: false });//关闭窗口
handlePreview = (file) => {//预览图片
this.setState({
previewImage: file.url || file.thumbUrl,
previewVisible: true,
});
};
handleChange = ({ fileList }) => this.setState({ fileList });//事件触发
handlePositiveChange = (e) =>{//事件触发具体函数
this.setState({positiveList:e.fileList});
if(e.file.response!==undefined){
//console.log("----handlePositiveChange--"+JSON.stringify(e.file.response.fileName))
this.setState({positivePhoto:e.file.response.positivePhoto});
}
if(this.state.positiveWordsState){//删除时，将该图片对象置空
this.setState({positivePhoto:null});
}
this.setState({positiveWordsState:false})
};
handleContraryChange = (e) =>{
this.setState({contraryList:e.fileList});
if(e.file.response!==undefined){
//console.log("----handleContraryChange--"+JSON.stringify(e.file.response.fileName))
this.setState({contraryPhoto:e.file.response.positivePhoto});
}
if(this.state.contraryWordsState){//删除时，将该图片对象置空
this.setState({contraryPhoto:null});
}
this.setState({contraryWordsState:false})
}
handlePositiveRemove =(file) =>{//删除事件
delAtta(this.props.workId,'vehiclelicense/positive',file.response.fileName);
this.setState({positiveWordsState:true});
}
handleContraryRemove =(file) =>{
delAtta(this.props.workId,'vehiclelicense/contrary',file.response.fileName);
this.setState({contraryWordsState:true});
}
beforeUpload =(file) =>{//上传限制，大小或格式
const isJPG = (file.type === 'image/jpeg' || file.type === 'image/png');
if (!isJPG) {
message.error('只能上传JPG文件!');
}
const isLt50M = file.size / 1024 / 1024 < 1.5;
if (!isLt50M) {
message.error('文件大小必须小于1.5MB!');
}
return isJPG && isLt50M;
};
渲染：
render() {
const { previewVisible, previewImage, positiveList,contraryList,positivePhoto,contraryPhoto} = this.state;
const {form} = this.props;
// this.getCarPhoto();deng
const actionURL=config.HOST+'/cardIdentification/post/';
const positiveData={userToken: JSON.parse(localStorage.getItem('user')).token,
workId:this.props.workId,
type:'positive',
catalog:'vehiclelicense/positive'};
const contraryData={userToken: JSON.parse(localStorage.getItem('user')).token,
workId:this.props.workId,
type:'contrary',
catalog:'vehiclelicense/contrary'};
const uploadButton = (
<div>
<Icon type="plus" />
<div className="ant-upload-text">请上传行驶证</div>
</div>
);
const {getFieldDecorator} = form;
const formItemLayout = {
labelCol: {span: 8},
wrapperCol: {span: 8},
};
布局代码：略。
（2）提交请求：
通过antd的upload的封装的url将请求发送给后端控制层进行处理。
（3）请求处理：后端
