一、跨域处理
1.1 manifest.json文件配置
"h5" : {"title" : "H5","devServer" : {"port" : 8080,"https" : false,"disableHostCheck" : true,"proxy" : {"/wxa" : {"target" : "https://api.weixin.qq.com", "changeOrigin" : true, "secure" : true, "pathRewrite" : {"^/app" : ""}},"/api" : {"target" : "https://api.weixin.qq.com", "changeOrigin" : true, "secure" : true, "pathRewrite" : {"^/api" : ""}}}},"router" : {"base" : "./"}}
1.2 请求https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=xxx-
uni.request({url: "/wxa/getwxacodeunlimit?access_token=84_mRo06Sz7S507_c8y81N5_1o5ZpYNL3SVbkLkaFbGy9QWFOYt3PDu8-o0fZIQ4Y7zd04hLK6d0eJtxv8RQNFeb9RwNh3yZd587TQOKTuufRTbK6XbgbZywvgT_6kKHTaAAASPB",method: "POST",data: {"scene": "a=1"},success(res) {...}})
