我目前正在使用微信管理平台api编写节点应用程序。但是，当我尝试使用管理平台 api 将拇指媒体图像文件上传到腾讯服务器时，我目前被卡住了。我有一个在微信上注册的订阅者帐户，我可以使用管理 api 平台成功获取我的微信帐户的访问令牌和关注者列表。以下是我用来上传到微信服务器的微信代码：

function uploadThumb(){

console.log('Inside uploadThumb');

var promise = new Promise(function(resolve,reject){

    resolve({
        then:function(onfullfill,onreject){
             fs.readdir(thumb_dir,function(err,files){
             if (err){
                onreject();
                throw err;
            }
            files.forEach(function(file){
                 fs.stat(thumb_dir+file, function(err, stats) {
                       var type = "thumb";
                       var upload_url = "http://file.api.wechat.com/cgi-bin/media/upload?access_token="+access_token+"&type="+type;
                     console.log('file name :'+file+': size :'+stats.size);
            restler.post(upload_url, {
                          multipart: true,
                          data: {
                                   "media['filename']": file,
                                   "media['content type']":"image/png",
                                   "media['file length']": stats.size,
                                   "media['file']": restler.file(thumb_dir+file, null, stats.size, null, "image/png")
                                }
                        }).on("complete", function(fdata,response) {
                              console.log('Status: ' + response.statusCode);
                              console.log('Thumb image data :'+fdata);
                              console.dir(response);
                             //var obj = JSON.parse(fdata);
                         //saveUploadMediaToDB(obj,file).then(onfullfill());
                            onfullfill();
                             });
                          });
                      });
                  });               
               }
          });
      });
      return promise;
   }

当我在节点中运行上述函数时，我得到的 HTTP 响应代码为 502。下面的文本/html 响应：

请指出正确的方向来帮助我，无论这种方法是正确的还是我做的事情基本上是错误的。

根据我在 Restler 文档中找到的内容，并将其与微信 API 文档进行比较，您似乎指定了错误的请求参数。

我想你可能需要更换

restler.post(upload_url, {
  multipart: true,
  data: {
    "media['filename']": file,
    "media['content type']":"image/png",
    "media['file length']": stats.size,
    "media['file']": restler.file(thumb_dir+file, null, stats.size, null, "image/png")
  }
[...]

沿着这些思路：

restler.post(upload_url, {
  multipart: true,
  data: {
    "media": restler.file(thumb_dir+file, null, stats.size, null, "image/png")
  }
[...]
