react-native使用Face++识别身份证，读取信息展示

按照官方文档的调用实例：

curl -X POST “https://api-cn.faceplusplus.com/cardpp/v1/ocridcard”
-F “api_key=<api_key>”
-F “api_secret=<api_secret>”
-F “[email protected]_file.jpg”

react-native使用Face++识别身份证，读取信息展示

api_key、 api_secret
官网的应用管理里面创建API Key 生成
根据需要，选择类型，这边文档里楼主用的是试用的

创建成功，下面圈出来的就是上面对应两个参数的值

image_file.jpg
是传入的身份证照片
楼主用的是formData方式上传的

代码块：

引入react-native-image-picker获取图片

 import ImagePicker from 'react-native-image-picker';


    getImage() {
        const options = {
            quality: 0.4,
            maxWidth: 500,
            maxHeight: 500,
            noData: true,
            storageOptions: {//是否做为临时图片存储
                skipBackup: true//在手机相册存储图片
            }
        };
        ImagePicker.launchImageLibrary(options, (response) => {
            console.log('Response = ', response);
            if (response.didCancel) {
                console.log('User cancelled photo picker');
            }
            else if (response.error) {
                console.log('ImagePicker Error: ', response.error);
            }
            else if (response.customButton) {
                console.log('User tapped custom button: ', response.customButton);
            }
            else {
                console.log('response==== ', response);

                let formData = new FormData();
                let file = {uri: response.uri, type: 'multipart/form-data', name: Date.parse(new Date()) + ".jpg"};
                this.setState({
                    CardImage: file,
                });
                formData.append('image_file', file);
                let url = 'https://api-cn.faceplusplus.com/cardpp/v1/ocridcard' + '?api_key=' + '**********' + '&api_secret=' + '*********'；
                console.log('formData--', formData);
                RTRequest.uploadPhoto(url, formData).then((responseText) => {
                    if (responseText) {
                        console.log('图片识别成功，返回数据：====', responseText);
                        if (responseText) {
                            this.setState({
                                cardsData: responseText.cards[0],
                            });
                        }
                    }
                })
                console.log('url==== ', this.state.url);
                console.log('cardsData==== ', this.state.cardsData);
            }
        });
    }
