busboy没有收到上传的文件

我的表格很简单。它使用ng-flow来处理文件上传:

<form class="form-horizontal" enctype="multipart/form-data">
    <div flow-init="{target: '/test', testChunks: false, query: {'_csrf': '{{csrf}}', 'somestring': 'teststring'} }"
         flow-files-submitted="data.flow.upload()"
         flow-name="data.flow">

         <input type="file" flow-btn/>
    </div>
</form>

选择图像后,ng-flow将对目标路线进行POST。看起来像是因为Request Payload有很多类似的东西而发送的图像:

1048576
------WebKitFormBoundaryw2YAG9m602ICPd0Q
Content-Disposition: form-data; name="flowCurrentChunkSize"

图像不是很大(约1MB)

在nodejs一侧(带快递):

var busboy = require('connect-busboy')({
    limits: {
        fileSize: 10 * 1024 * 1024
    }
});
router.post('/test', busboy, function(req, res) {
    console.log('test called');
    console.log(req.busboy);
    if (req.busboy) {
        req.busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
            console.log("this is fieldname: " + fieldname);
        });
        req.busboy.on('field', function(fieldname, val, fieldnameTruncated, valTruncated) {
            console.log('Field [' + fieldname + ']: value: ' + inspect(val));
        });
    }

    res.json();
});

req.busboy会返回一个包含所有内容的对象,但req.busboy.on('file'...req.busboy.on('field'...)永远不会触发。

为什么busboy看不到我的字符串和图像?

您需要将请求传递给busboy,以便它可以解析表单:

req.pipe(req.busboy);
