ps: 最近有点忙。今天抽时间记录下， 项目中应用到： 身份认证， 使用 lrz 插件上传图片。

写的不好，欢迎各位指点，谢谢。

效果图

引入lrz文件

 /*
  引入外部上传压缩图片js
  第一：在webpack.base.conf.js的module.exports中resolve中进行引用：
  第二：在 alias中加入  'lrz':resolve('src/assets/uploadjs/lrz.bundle.js'), 加别名
  第三：在需要组件中引入lrz
 */

resolve: {
    extensions: ['.vue', '.js', '.json', '.scss' ,'*'],
    alias: {
       'vue$': 'vue/dist/vue.esm.js',
       '@': resolve('src'),
       'lrz':resolve('src/assets/uploadjs/lrz.all.bundle.js')
    }
},
# 注意： 引入 all的文件兼容性好

初始化

<script>
	import lrz from 'lrz'  //引入别名
	export default {
        name: 'identityCard',
        data() {
            return {
                name: '',
                identity: '',
                config: {  //压缩图片控制(自定义)
                    width: 720,
                    height: 320,
                    quality: 0.6
                },
                /**
                * file: 文件流
                * urlinfo： 上传后图片
                * urlshow： 是否显示上传后图片
                */
                img1: {"file": "", "urlinfo": "", "urlshow": false}, //身份证头像面
                img2: {"file": "", "urlinfo": "", "urlshow": false},//身份证国徽面
                img3: {"file": "", "urlinfo": "", "urlshow": false}, //手持身份证
                identityStatus: false,//审核状态
                status_txt: '',//状态文字信息
                status_reason: '',//状态原因
                auditBtnstatus: true, //提交按钮是否显示
                files: '', //文件流
                infos: {}, //保存用户信息
                identityInfo: {}, //身份证信息
            }
        },
    }
</script>

判断展示审核未通过原因及重选

created(){
    //获取用户信息（是否有认证的信息）
    this.infos = JSON.parse(getStore('userInfo')) || {};
    let identityObj = this.infos.extends;
    this.identityInfo = identityObj;

    //需求： 展示审核未通过的原因，及可重新选择上传
    if(this.identityInfo != {}) {
        if(this.infos.isauth == 2) {
            this.identityStatus = true;
            this.status_txt ='未通过';
            this.status_reason = this.identityInfo.remark;
            this.anew_one = true;
            this.anew_two = true;
            //展示已上传过的信息
            this.name = this.identityInfo.name;
            this.identity = this.identityInfo.card_id;
            this.img1.urlshow = true;
            this.img2.urlshow = true;
            this.img1.urlinfo = this.identityInfo.card_front;
            this.img2.urlinfo = this.identityInfo.card_behind;

            //未通过，直接点击提交按钮，文件流赋值上次值，否则为空后台不通过
            this.img1.file = this.identityInfo.card_front;
            this.img2.file = this.identityInfo.card_behind;
        }
    }
},

解决上传图片安卓与IOS兼容问题

mounted() {
    //解决上传图片时capture="camera"在安卓与IOS的兼容性问题（在IOS只能拍照，不能选相册）
    var ua = navigator.userAgent.toLowerCase();//获取浏览器的userAgent,并转化为小写——注：userAgent是用户可以修改的
    var isIos = (ua.indexOf('iphone') != -1) || (ua.indexOf('ipad') != -1);//判断是否是苹果手机，是则是true
    if (isIos) {
        $("input:file").removeAttr("capture");
    };
},

选择身份证图片

chooseFile (index,e) {
    // console.log(index); console.log(e);
    var self = this
    var file = e.target.files[0];

    lrz(file, self.config)
        .then(function (rst) {
        // console.log(file.name)
        if(Number(index) == 1){
            self.img1.urlinfo = rst.base64;
            self.img1.urlshow = true;
            self.img1.file = file;
            self.anew_one = true;
        }else if(Number(index) == 2){
            self.img2.urlinfo = rst.base64;
            self.img2.urlshow = true;
            self.img2.file = file;
            self.anew_two = true;
        }
    })
        .catch(function (err) {
        this.$toast('上传失败，请重新上传');
    })
        .always(function () {
        // 清空文件上传控件的值
        e.target.value = null
    })
},

上传图片

doUpload: function () {
    //非空判断省略
    
    let regEn = /[`~!@#$%^&*()_+<>?:"{},.\/;'[\]\s+=]/im,
        regCn = /[·！#￥（——）：；“”‘、，|《。》？、【】[\]]/im;

        return;
    }

        return;
    }

    let param = new FormData() // 创建form对象
    param.append('name', this.name) // 添加form表单中其他数据
    param.append('card_id', this.identity)
    param.append('card_front', this.img1.file) // 通过append向form对象添加数据

    //提交身份认证
    this.loading('提交中...');
    this.axios.identityAuthentication(param).then((response) => {
        this.$toast.clear()
        let datas = response.data;
        if(parseInt(datas.code) == 200){
            this.showAudit = true;
        }else {
            this.$toast(datas.msg);
        }
    })
},
    
isIdentity(card) {
   // 身份证号码为15位或者18位，15位时全为数字，18位前17位为数字，最后一位是校验位，可能为数字或字符X 
   var reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/; 
   if(!reg.test(card)){ 
      return false; 
   }else {
      return true;
   }
},
