• 当前 Bug 的表现（可附上截图）

wx.request 设置content-type 为multipart/form-data ，请求头如下：

POST /mindoffice/visitor_unreservations/subscribeBill HTTP/1.1 Host: qas.zjzlnet.com Content-Length: 20 Pragma: no-cache Cache-Control: no-cache Origin: http://127.0.0.1:34785 User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1 wechatdevtools/1.02.1809111 MicroMessenger/6.5.7 Language/zh_CN webview/ token/61f11dc1d5bc1cfd264bbe33ae8d2f95 content-type: multipart/form-data Accept: */* Referer: https://servicewechat.com/wx04c25e121b8ce5df/devtools/page-frame.html Accept-Encoding: gzip, deflate Accept-Language: zh-CN,zh;q=0.8 Connection: keep-alive    {"data":"test data"}

提交的参数没有被 boundary 包裹，后台拒绝了请求，提示 no multipart boundary was found

• 预期表现

POST /mindoffice/visitor_unreservations/subscribeBill HTTP/1.1 Content-Type: multipart/form-data; boundary=7f81e6d3-da78-4610-82b5-b4906d630ab3 Content-Length: 407 Host: 115.29.7.124 Accept-Encoding: gzip User-Agent: okhttp/3.6.0 Connection: keep-alive    --7f81e6d3-da78-4610-82b5-b4906d630ab3 content-disposition: form-data; name="data" Content-Length: 255    test data --7f81e6d3-da78-4610-82b5-b4906d630ab3--

wx.uploadFile支持 multipart/form-data，但是我这个接口不需要传文件，只需传键值对，就是这么奇怪。。

请问该怎么解决呢？谢谢～
