uploadFile一加header就报错？

if (!params.method) {

params.method = "GET";

params.header = {

'content-type': 'application/json',

'id': '2',

'token': wx.getStorageSync('token')

}

} else {

params.header = {

"Content-Type": "application/x-www-form-urlencoded",

'id': '2',

'token': wx.getStorageSync('token')

}

}

wx.chooseImage({

success: (res) => {

const tempFilePaths = res.tempFilePaths

wx.setStorageSync('avatar', res.tempFilePaths[0])

console.log(wx.getStorageSync('avatar'))

wx.uploadFile({

url: config.base_url + params.url,

filePath: tempFilePaths[0],

header: params.header,

name: params.name,

formData: params.data,

success: (res) => {

console.log(res)

params.success(res);

},

fail: (err) => {

console.log(err)

}

})

},

fail: (err) => {

console.log(err)

}

})

一加header就报uploadFile:fail Error: socket hang up的错，但注释掉header又无法传token.哪位大神知道怎么解决吗。。
