前端vue单个文件上传支持图片，压缩包以及文件 ， 下载完整代码请访问uni-app插件市场址:https://ext.dcloud.net.cn/plugin?id=13066

效果图如下：

使用方法

 <!-- photoList：选择的图片数组  @click：图片选择事件-->  <ccChooseImgsView :photoList="photoList" @click="addPhotoClick"></ccChooseImgsView>  addPhotoClick() {  uni.hideLoading();  let myThis = this;  if (myThis.photoList.length >= 1) {  myThis.photoList = [];  }  uni.chooseImage({  count: 1,  sizeType: ['compressed'], //可以指定是原图还是压缩图，默认二者都有  sourceType: ['album'], //从相册选择  success: function(res) {  myThis.photoList = [{'filePath':res.tempFilePaths[0]}];  console.log('选择图片 =' + JSON.stringify(myThis.photoList));  }  });  },  if (this.photoList.length > 0) {  myFilePath = this.photoList[0].filePath;  }  // 服务器地址上传地址 仅为示例，非真实的接口地址  let baseUrl = "http://gzcc.com/cc//appSc/up"  uni.uploadFile({  url: baseUrl, //仅为示例，非真实的接口地址  filePath: myFilePath, //文件路径  name: 'image', //服务端文件接受key  formData: this.myParamData,  success: (uploadFileRes) => {  uni.hideLoading();  let dataDic = JSON.parse(uploadFileRes.data);  console.log('uploadFileRes成功 = ' + JSON.stringify(uploadFileRes));  console.log('datadic成功 = ' + typeof(dataDic));  console.log('code码 = ' + dataDic['code']);  }  });  

HTML代码部分

 <template>  <view class="content" v-if="seen">  <form @submit="formSubmit" @reset="formReset">  <view class="inputView">  <text class="leftTitle">交通指引</text>  </view>  <textarea class="rightTextarea" name="direct" placeholder=" 请输入交通指引" />  <view class="inputView">  <text class="leftTitle">房屋介绍</text>  </view>  <textarea class="rightTextarea" name="village" placeholder=" 请输入房屋介绍" />  <view class="inputView">  <text class="leftTitle">添加房源照片（仅可添加1张）</text>  </view>  <!-- photoList：选择的图片数组  @click：图片选择事件-->  <ccChooseImgsView :photoList="photoList" @click="addPhotoClick"></ccChooseImgsView>  <view class="uni-btn-v">  <button class="botBtn" type="primary" form-type="submit">提交</button>  <view class="tipText"> 注意事项: 请确保您填写的房屋信息真实无误 </view>  </view>  </form>  </view>  </template>  

JS代码 （引入组件 填充数据）

 <script>  import Vue from 'vue';  import ccChooseImgsView from '../../components/ccChooseImgsView.vue';  export default {  components: {  ccChooseImgsView  },  data() {  return {  photoList: [],  seen: true,  myParamData: {},  isClick: false,  };  },  onLoad: function(e) {  },  methods: {  formSubmit: function(e) {  console.log('form发生了submit事件，携带数据为：' + JSON.stringify(e.detail.value));  if (this.isClick) {  let that = this;  setTimeout(function() {  that.isClick = false;  }, 600)  return;  }  this.isClick = true;  var formdata = e.detail.value;  this.myParamData = Object.assign(this.myParamData, formdata);  console.log('页面3 myParamData=' + JSON.stringify(this.myParamData));  if (formdata['direct'].length < 2) {  uni.showModal({  content: '请输入交通指引',  showCancel: false  });  return;  }  if (formdata['village'].length < 2) {  uni.showModal({  content: '请输入所在小区介绍',  showCancel: false  });  return;  }  if (this.photoList.length < 1) {  uni.showModal({  content: '请添加房源照片',  showCancel: false  });  return;  }  uni.showLoading({  title: '上传中'  })  let myFilePath = '';  if (this.photoList.length > 0) {  myFilePath = this.photoList[0].filePath;  }  // 服务器地址上传地址 仅为示例，非真实的接口地址  let baseUrl = "http://gzcc.com/cc//appSc/up"  uni.uploadFile({  url: baseUrl, //仅为示例，非真实的接口地址  filePath: myFilePath, //文件路径  name: 'image', //服务端文件接受key  formData: this.myParamData,  success: (uploadFileRes) => {  uni.hideLoading();  let dataDic = JSON.parse(uploadFileRes.data);  console.log('uploadFileRes成功 = ' + JSON.stringify(uploadFileRes));  console.log('datadic成功 = ' + typeof(dataDic));  console.log('code码 = ' + dataDic['code']);  }  });  },  addPhotoClick() {  uni.hideLoading();  let myThis = this;  if (myThis.photoList.length >= 1) {  myThis.photoList = [];  }  uni.chooseImage({  count: 1,  sizeType: ['compressed'], //可以指定是原图还是压缩图，默认二者都有  sourceType: ['album'], //从相册选择  success: function(res) {  myThis.photoList = [{'filePath':res.tempFilePaths[0]}];  console.log('选择图片 =' + JSON.stringify(myThis.photoList));  }  });  },  }  };  </script>  

CSS

 <style>  .uni-form-item .title {  padding: 20rpx 0;  }  .content {  display: flex;  flex-direction: column;  width: 100%;  height: auto;  }  .inputView {  flex-direction: row;  display: flex;  height: 40px;  align-items: center;  width: 100%;  }  .line {  width: 90%;  height: 2rpx;  margin-left: -2rpx;  background-color: #f8f8f8;  margin-left: 5%;  }  .leftTitle {  margin-left: 40rpx;  width: 284px;  height: 32px;  line-height: 32px;  font-size: 28rpx;  color: #333333;  }  .rightTextarea {  margin-left: 5%;  width: 90%;  height: 106px;  line-height: 40rpx;  border-radius: 12rpx;  border: solid 1px #F5F5F5;  font-size: 15px;  }  .uni-btn-v {  width: 100%;  height: auto;  }  .botBtn {  width: 90%;  margin-top: 36px;  height: 48px;  }  .tipText {  width: 100%;  margin-left: 0px;  text-align: center;  color: #666666;  margin-top: 36px;  margin-bottom: 36px;  font-size: 28rpx;  }  </style>
