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'...
和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?
答案 0 :(得分:2)
您需要将请求传递给busboy,以便它可以解析表单:
req.pipe(req.busboy);
