裡面涉及到的小程式元件form,input,button的使用詳解，請參考：

首先微信端頁面程式碼index.wxml：

<form bindsubmit='formSubmit'><view class='input_line'><label>使用者名稱：</label><input name="username" id='username'></input></view><view class='input_line'><label>密碼：</label><input type="password" name="passwordd" id='passwordd'></input> </view><button type='primary' form-type='submit'>登入</button></form>

其次index.js程式碼：

Page({ data:{ }, formSubmit: function (e) { console.log(e.detail.value); var objvalue = e.detail.value; wx.request({ url: "http://197.10.1.150:8080/GW/hlsxy!loginWX.action", data: { account: objvalue.username, passwd: objvalue.passwordd }, method: "GET", success: function (root) { console.log(root.data); }, fail: function (res) { console.log("登入失敗");} }) }})

後臺接收資料的action程式碼：

/**
* 登入方法
* 
*/
public String loginWX(){
Map<String, Object> map = new HashMap<String, Object>();
Videouser u = hlVideoManager.searchUserByLoginNameAndPwd(account, passwd);
if (u == null) {
map.put("msg", "nullUser");
JSONObject objet = JSONObject.fromObject(map);
msg = objet.toString();
System.out.println(msg);
return "wxloginerror";
} else {
Map<String, Object> session = ActionContext.getContext()
.getSession();
session.put("user", u);
map.put("msg", "userOk");
JSONObject objet = JSONObject.fromObject(map);
msg = objet.toString();
System.out.println(msg);
return "wxloginOk";
}
}
