errcode: 41005，mediaId: undefined，上传临时图片素材时提示的错误

Question

content发送1-4之间的消息能够正常回复，一发5、6就不行，看后台的情况是无法获取到data

代码如下:

		else if (content === '5'){
			var data = yield wechatApi.uploadMaterial('image',path.join(__dirname,'/2.jpg'))
			
			reply = {
				type: 'image',
				mediaId: data.media_id
			}
			console.log(data)
			console.log(reply)
		}	

Wechat.prototype.uploadMaterial = function(type, filepath){
    var that = this
    var form = {//构造一个表单
        media: fs.createReadStream(filepath)
    }

    var appID = this.appID
    var appSecret = this.appSecret
    // var url = api.accessToken + '&appid=' + appID + '&secret=' + appSecret


    return new Promise(function(resolve,reject){//Promise 实例
        that
        .fetchAccessToken()
        .then(function(data){
            var url = api.upload + 'access_token=' + data.
            access_token + '&type=' + type

            request({methos: 'POST',url: url, formData:form, json: 
                true}).then(function(response){
                    var _data = response[1]

                    if(_data){
                        resolve(_data)
                        console.log(_data)
                    }
                    else{
                        throw new Error('Upload material fails')
                    }
                })
                .catch(function(err){
                    reject(err)
                })
            })
    })
}

用 response.body 代替 response[1] 试试看呢

找到问题所在了，原来是我那个method拼错了。

  有可能是你那个api没有写成如下的样子， 一定要认真阅读官方的开发文档
  var api = {
  	accessToken: prefix + 'token?grant_type=client_credential',
  	upload: prefix + 'media/upload?'
  }

 用 response.body 代替 response[1]之后报错如下：
