wx.upload后后台接收不到图片文件
上传后， 后台解析request内容为空，是什么问题？
wx.uploadFile({
url: ‘http://192.168.1.102:8888/base\_service/file/upload’,
filePath: that.data.tempFilePaths[0],
method: ‘POST’,
name: ‘fileName’, // 文件对应的 key , 开发者在服务器端通过这个 key 可以获取到文件二进制内容
header: { “content-type”: “multipart/form-data”, ‘accept’: ‘application/json’, }, //HTTP 请求 Header , header 中不能设置 Referer
formData: {
‘user’: ‘test’,
},
success: function (res) {
console.log(statusCode, res);
wx.showModal({
title: ‘上传文件返回状态’,
content: statusCode+‘成功’ + res.msg,
success: function (res) {
if (res.confirm) {
console.log(‘用户点击确定’)
}
}
})
// App.HttpService.savFiles(params)
// .then(data => {
// console.log(data)
// if (data.ret == 0) {
// this.showToast(data.msg)
// }
// })
}, fail: function (err) {
console.log(statusCode, err);
}
});
