Question

我在我的Sails.js项目中有多部分表单，它提交了2个不同的文件（第一个音频然后图像）以及一些文本参数。在大多数情况下，文件相当小，一切正常。但是当我尝试更大的音频文件（ 33MB ）时，我在接收器中为我的图像字段获取了空文件数组。这是一些代码。

控制器：

var uploadParamNames = ['audio', 'image'];

async.map(uploadParamNames, 
    function (file, cb) {

       sails.log(req.file(file)._files)
       req.file(file).upload(
       {
           adapter:     require('skipper-gridfs'),
           uri:         sails.config.connections.mongoConnection.url + '.' + file           
       }, 
       function (err, files) {
           // save the file, and then:
           return cb(err, files);
    });

}, function doneUploading(err, files) {
...
});

基本上这里我得到了以下音频和图像日志：

[ { stream: [Object], status: 'bufferingOrWriting' } ]
[]

我尝试了调试，发现在图像字段的情况下，它从未到达文件实际写入prototype.onFile.js行up.writeFile(part);的行。

此外，调试日志还会打印以下内容：

不确定原因，但似乎控件已经在写入图像文件之前传递给应用程序。同样，这只发生在更大的音频文件中。有办法解决这个问题吗？

修改更多调试显示在写入映像文件之前调用receivedFirstFileOfRequest侦听器。这是合乎逻辑的，因为它实际上会侦听第一个文件上传，但是如何处理下一个文件？

修改啊......文件根本不需要非常大。 29KB文件通过，320KB不通过......

当以多上传形式上传大文件时，Sails.js文件上传返回空文件数组
