七牛云直传文件报错 NextPart: EOF" Bad Request

Question

直接上传文件报错。
报错信息
"error":"invalid multipart format: multipart: NextPart: EOF"} Bad Request

我的请求信息：

POST / HTTP/1.1
Accept: /
Authorization: Acceskey:signature
Host: up.qiniu.com
Content-Type: multipart/form-data; boundary=------------------------7aa9c49f35d7c3fc
Content-Length: 8

返回的响应信息：

• upload completely sent off: 8 out of 8 bytes

< HTTP/1.1 400 Bad Request

传输的from data以下格式：
------------------------7aa9c49f35d7c3fc
Content-Disposition: form-data; name="file"; filename="gpossext.0.0"
Content-Type: application/octet-stream
Content-Transfer-Encoding: binary<00000000>
------------------------7aa9c49f35d7c3fc
Content-Disposition: form-data; name="token"< Acceskey:signature=>
------------------------7aa9c49f35d7c3fc
密钥部分就不展示了。目前怀疑是上传的from data格式错了，请指点具体格式怎么拼最好有例子？？
