麻烦大佬帮忙看下axios.post的这个传参有什么问题吗，后台接收不到参数数据

调试时候 data是有值的

var data = {
        title: vm_apk_basi.apk_name,
        alias:  vm_apk_basi.alias,
        typeId: vm_apk_basi.apk_subclassification,
        icon: vm_apk_basi.icon,
        fileUrl: vm_apk_basi.file_url,
        fileMd5: vm_apk_basi.file_md5,
        fileSize: vm_apk_basi.file_size,
        description: vm_apk_basi.description,
        apkInfo:{
            title: vm_apk_basi.file_name,
            identifier: vm_apk_basi.file_pkg,
            versionCode: vm_apk_basi.file_version,
            versionName: vm_apk_basi.file_versionName,
            minSdkVersion: vm_apk_basi.file_minSdk,
            targetSdkVersion: vm_apk_basi.file_targetSdk,
        },
        screenshot: dimgPath
    };
    var config = {
        headers:{
            'Content-type': 'application/x-www-form-urlencoded'
        }
    }
    axios.post("http://192.168.199.153:10001/test/apk/save",data,config)
    .then(response => {
        console.log(response)
    })
    .catch(function(error){
        console.log(error)
    })
