获取qcode后端代码出错

[111635]

getToken: function() {
console.log('fn：getToken');
var that = this;
new promise((resolve, reject) = >{
console.log('进入Promise方法了');
request({
method: 'GET',
url: wx_gettoken_url
},
function(err, res, body) {
if (res) {
resolve({
isSuccess: true,
data: JSON.parse(body)
});
} else {
console.log(err);
reject({
isSuccess: false,
data: err
});
}
});
}).then(proData =>{
that.getQrcode(proData);
});
}
大神来帮忙看看这段代码有什么问题，一直提示语法有问题，就是找不到。。。

getQrcode: function(proData) {
console.log("fn:getQrcode");
if (proData.isSuccess) {
postData = JSON.stringify(postData);
request({
method: 'POST';
url: 'https://api.weixin.qq.com/cgi-bin/wxaapp/createwxaqrcode?access_token=' + proData.data.access_token;
body: postData
}).pipe(fs.createWriteStream('./public/images/index.png'));
} else {
console.log('Promise请求数据出错');
}
};
第一行代码报错了。

expected'}'to match '{' from line 14 and instead saw 'getQrcode' missing ';' before statement expected '(end)' and instead saw ':'错误提示是这个
