问题解决了！formid 获取到之后只要调用了wx.request() 方法，就算这个formid没用过也会失效！所以整个方法区只能在第一个wx.request()的方法内使用formid

为了大家能看全  ！我再贴些代码如下：

//form表单提交触发的事件

changeIntoIdentification:function(e){

var that=this;

var currentStatu = e.currentTarget.dataset.statu;

that.util(currentStatu)

var formId = e.detail.formId;

console.log("formI 》"+formId+"《《《");

that.setData({

showModalStatus: false,

changeIntoIdentification: e.detail.value.changeIntoIdentification

});

var changeIntoIdentification = that.data.changeIntoIdentification;

var identification = wx.getStorageSync("identification");

var rgisterName = wx.getStorageSync("rgisterName");

if (identification != changeIntoIdentification && changeIntoIdentification != ""){

wx.request({

url: 'https://www.gcjxglzx.com/' + "*******" +'/getUserInfoByCondition',

method: 'POST',

header: {

'content-type': 'application/x-www-form-urlencoded'

},

success: function (res) {

if (res.data.status == '0' && res.data.data != null){

var changeIntoRegisterName = res.data.data[0].registerName;

var wxUser = res.data.data[0].wxUser //转入人的消息推送的微信

var len = changeIntoRegisterName.length - 1;

var xing = '';

for (var i = 0; i < len; i++) {

xing+= '*';

}

that.setData({

hiddenmodalput: true

});

var name = changeIntoRegisterName.substring(0, 1) + xing;

wx.showModal({

title: '是否将设备转给',

content: name,

success: function (res) {

if (res.confirm) {

var url = that.data.messagePushUrl

if (url != null && url != ""){

var time = new Date();

//*******************************重点在下边*************************//

wx.request({

url: url,//发送模版消息的接口地址，已经拼接里access_token

//

method: 'POST',

header: {

'content-type': 'application/json'

},

data:{

touser: wxUser,//接收消息的用户

template_id: "_-dTL2OwXZJDsRDymy4I4K3HS2-v-GH27pQyV-_jWw4",

page:"/page-payImg/payImg",

form_id: formId,

value: {

keyword1: { //申请人

value: rgisterName,

color: "#173177"

},

keyword2: {//详情

value: that.data.device.machineryType + that.data.device.deviecBrand + that.data.device.plateSubject+"设备申请转入！点击下方查看详情",

color: "#173177"

},

keyword3: {//时间

value: "2015年01月05日 12:30",

color: "#173177"

},

},

emphasis_keyword: "keyword2.DATA"

},

success: function (resmsg) {

var errcode = resmsg.data.errcode

console.log("发送状态>>>>"+errcode);

}

})

}

} else if (res.cancel) {

console.log('用户点击取消')

}

}

})

}else{

wx.showToast({

title: '提醒转入人注册或重新添加转入人',

duration: 2500,

mask: true

});

that.setData({

hiddenmodalput: false

});

//************上面的请求是调用小程序发送模板消息的接口！为啥一直是form_id**********************//

}

}

})

} else if (identification == changeIntoIdentification || changeIntoIdentification == ""){

wx.showToast({

title: '转入人错误',

duration: 2500,

mask:true

})

}

},

似乎好多人都是用后台调用的

发送模板消息”的api接口（
