可以把 调用 uploadMaterial 方法的代码也贴一下么？
然后，在 request(options) 前面，把 options 也打印一下：
console.log(options)
看看是什么内容，记得 request 在使用之前，是需要 promisify 一下的：
var request = Promise.promisify(require('request'))

附上上传素材的代码：
Wechat.prototype.uploadMaterial = function(type,material,permanent) {
var that = this;
var form = {};
var uploadUrl = api.temporary.upload;
var _=require('lodash');
if(permanent){
uploadUrl = api.permanent.upload;
_.extend(form, permanent);
}
if(type === 'pic'){
uploadUrl = api.permanent.uploadImg;
}
if(type === 'news'){
uploadUrl = api.permanent.uploadNews;
form = material;
}
else{
form = fs.createReadStream(material);
}
console.log('上传素材的form如下：\n');
console.log(form);
return new Promise(function(resolve,reject){
that.fetchAccessToken()
.then(function(data){
var url = uploadUrl + '&access_token=' + data.access_token;
if(!permanent){
url += '&type=' + type;
}else{
form.access_token = data.access_token;
}
var options = {
method:'POST',
url:url,
json:true
}
if(type === 'news')
{
options.body = form;
}else{
options.formData = form;
}
request(options).then(function(res){
var _data = res.body;
if(_data){
resolve(_data);
}else{
throw new Error('Upload material failed.')
}
})
.catch(function(err){reject(err) })
})
});
}
