formdata 文件上传问题

formdata上传文件为空

1.项目中请求拦截器进行了加密处理

// http请求拦截器
var loadinginstace
axios.interceptors.request.use(
    config => {
        config.showLoading = true
        if (config.data != {}) {  //加密封装 
            if (typeof config.data == "object") {
                config.data = {
                    "requestData": unit.encrypt(JSON.stringify(config.data))
                }
            } else {
                config.data = {
                    "requestData": unit.encrypt(config.data)
                }
            }
        }

        if (config.Type != undefined) {
            config.headers["Content-Type"] = config.Type
        } else {
            config.data = Qs.stringify(config.data);
        }
        if (localStorage.user_token) {
            config.headers.Authorization = 'Bearer ' + localStorage.user_token
        }
        if (config.showLoading) {
            showFullScreenLoading();
        }

        return config;
    },
    error => {
        Message.error({
            background: true,
            duration: 0,
            content: '加载超时'
        });
        Message.destroy()
        return Promise.reject(error)
    })

当调用上传文件接口 formdata 就会进行加密 文件上传失败

2.需要吧上传文件接口 跳过加密封住

跳过加密

  if (config.data != {} && config.url != "/applyLand/uploadFile") //加密封装

axios.interceptors.request.use(
    config => {
        config.showLoading = true
        if (config.data != {} && config.url != "/applyLand/uploadFile") {  //加密封装 
            if (typeof config.data == "object") {
                config.data = {
                    "requestData": unit.encrypt(JSON.stringify(config.data))
                }
            } else {
                config.data = {
                    "requestData": unit.encrypt(config.data)
                }
            }
        }

        if (config.Type != undefined) {
            config.headers["Content-Type"] = config.Type
        } else {
            config.data = Qs.stringify(config.data);
        }
        if (localStorage.user_token) {
            config.headers.Authorization = 'Bearer ' + localStorage.user_token
        }
        if (config.showLoading) {
            showFullScreenLoading();
        }

        return config;
    },
    error => {
        Message.error({
            background: true,
            duration: 0,
            content: '加载超时'
        });
        Message.destroy()
        return Promise.reject(error)
    })

跳过加密 请求就成功发布
