上述代码中，程序在Vue-Simple-Uploader上传插件的upload-start、upload-progress、upload-success和upload-error事件中，分别定义了上传开始、上传进度、成功和上传失败的回调函数。

示例1：使用Vue-Simple-Uploader上传单个文件

以下是使用Vue-Simple-Uploader上传单个文件的示例：

<template>
  <div>
    <vue-simple-uploader
      ref="uploader"
      :uploadUrl="uploadUrl"
      :headers="headers"
      :params="params"
      :multiple="false"
      :accept="accept"
      :maxSize="maxSize"
      :maxFiles="1"
      :autoUpload="autoUpload"
      :withCredentials="withCredentials"
      @upload-success="onUploadSuccess"
      @upload-error="onUploadError"
    >
      <button slot="browse">选择文件</button>
    </vue-simple-uploader>
  </div>
</template>

<script>
import VueSimpleUploader from 'vue-simple-uploader';

export default {
  components: {
    VueSimpleUploader,
  },
  data() {
    return {
      uploadUrl: 'http://example.com/upload',
      headers: {
        Authorization: 'Bearer ' + localStorage.getItem('token'),
      },
      params: {
        userId: 123,
      },
      multiple: false,
      accept: 'image/*',
      maxSize: 1024 * 1024 * 10, // 10MB
      maxFiles: 1,
      autoUpload: true,
      withCredentials: true,
    };
  },
  methods: {
    onUploadSuccess(response) {
      console.log('Upload success:', response);
    },
    onUploadError(error) {
      console.error('Upload error:', error);
    },
  },
};
</script>

上述代码中，程序设置了multiple为false，maxFiles为1，表示只能上传单个文件。其他属性和事件处理函数与前面的示例相同。

示例2：使用Vue-Simple-Uploader上传多个文件

以下是使用Vue-Simple-Uploader上传多个文件的示例：

<template>
  <div>
    <vue-simple-uploader
      ref="uploader"
      :uploadUrl="uploadUrl"
      :headers="headers"
      :params="params"
      :multiple="true"
      :accept="accept"
      :maxSize="maxSize"
      :maxFiles="maxFiles"
      :autoUpload="autoUpload"
      :withCredentials="withCredentials"
      @upload-success="onUploadSuccess"
      @upload-error="onUploadError"
    >
      <button slot="browse">选择文件</button>
    </vue-simple-uploader>
  </div>
</template>

<script>
import VueSimpleUploader from 'vue-simple-uploader';

export default {
  components: {
    VueSimpleUploader,
  },
  data() {
    return {
      uploadUrl: 'http://example.com/upload',
      headers: {
        Authorization: 'Bearer ' + localStorage.getItem('token'),
      },
      params: {
        userId: 123,
      },
      multiple: true,
      accept: 'image/*',
      maxSize: 1024 * 1024 * 10, // 10MB
      maxFiles: 5,
      autoUpload: true,
      withCredentials: true,
    };
  },
  methods: {
    onUploadSuccess(response) {
      console.log('Upload success:', response);
    },
    onUploadError(error) {
      console.error('Upload error:', error);
    },
  },
};
</script>

上述代码中，程序设置了multiple为true，maxFiles为5，表示可以上传多个文件，最多上传5个文件。其他属性和事件处理函数与前面的示例相同。

通过遵循上述步骤和示例，您可以使用Vue-Simple-Uploader上传插件上传文件和图片，并处理上传过程中的状态变化。
