在使用若依的框架时,发现若依移动端框架中已经封装好了一个upload.js用于文件上传,自己在这个版本的基础上稍作改动,成功实现文件上传功能
若依公共的 upload.js
import store from '@/store'
import config from '@/config'
import { getToken } from '@/utils/auth'
import errorCode from '@/utils/errorCode'
import { toast, showConfirm, tansParams } from '@/utils/common'
let timeout = 10000
const baseUrl = config.baseUrl
const upload = config => {
// 是否需要设置 token
const isToken = (config.headers || {}).isToken === false
config.header = config.header || {}
if (getToken() && !isToken) {
config.header['Authorization'] = 'Bearer ' + getToken()
}
// get请求映射params参数
if (config.params) {
let url = config.url + '?' + tansParams(config.params)
url = url.slice(0, -1)
config.url = url
}
return new Promise((resolve, reject) => {
uni.uploadFile({
timeout: config.timeout || timeout,
url: baseUrl + config.url,
filePath: config.data,
name: config.name || 'file',
header: config.header,
formData: config.formData,
success: (res) => {
let result = JSON.parse(res.data)
const code = result.code || 200
const msg = errorCode[code] || result.msg || errorCode['default']
if (code === 200) {
resolve(result)
} else if (code == 401) {
showConfirm("登录状态已过期,您可以继续留在该页面,或者重新登录?").then(res => {
if (res.confirm) {
store.dispatch('LogOut').then(res => {
uni.reLaunch({ url: '/pages/login/login' })
})
}
})
reject('无效的会话,或者会话已过期,请重新登录。')
} else if (code === 500) {
toast(msg)
reject('500')
} else if (code !== 200) {
toast(msg)
reject(code)
}
},
fail: (error) => {
console.log("error", error);
let { message } = error
if (message == 'Network Error') {
message = '后端接口连接异常'
} else if (message.includes('timeout')) {
message = '系统接口请求超时'
} else if (message.includes('Request failed with status code')) {
message = '系统接口' + message.substr(message.length - 3) + '异常'
}
toast(message)
reject(error)
}
})
})
}
export default upload
自己再封装一个 js 文件,此处命名 upload.js 但不和若依的文件放在同一个目录下
import upload from '@/utils/upload.js'
export function uploadFile(data) {
return upload({
url: '/common/upload',
method: 'post',
data: data
})
}
在文件中调用需要先引入
import { uploadFile } from '@/api/common/upload.js'
再在 uni.chooseImage 中调用文章来源:https://www.toymoban.com/news/detail-507034.html
selectPic() {
var _this = this
uni.chooseImage({
count: 1, //默认9
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) {
uploadFile(res.tempFilePaths[0]).then(fileRes => {
console.log(fileRes);
fileRes = JSON.parse(fileRes)
uni.showToast({
title: "图片上传成功,保存生效",
icon: "none"
})
});
}
});
},
controller 代码文章来源地址https://www.toymoban.com/news/detail-507034.html
/**
* 通用上传请求(单个)
*/
@PostMapping("/upload")
public AjaxResult uploadFile(MultipartFile file) throws Exception
{
try
{
// 上传文件路径
String filePath = RuoYiConfig.getUploadPath();
// 上传并返回新文件名称
String fileName = FileUploadUtils.upload(filePath, file);
String url = serverConfig.getUrl() + fileName;
AjaxResult ajax = AjaxResult.success();
ajax.put("url", url);
ajax.put("fileName", fileName);
ajax.put("newFileName", FileUtils.getName(fileName));
ajax.put("originalFilename", file.getOriginalFilename());
return ajax;
}
catch (Exception e)
{
return AjaxResult.error(e.getMessage());
}
}
