我目前正在使用API端点。
将数据发布到端点/authenticate
后,我使用plaidClient.getAuthUser
功能获取用户的帐户信息,然后我尝试使用{{1} }返回帐户数据。
运行之后:
res.json
我成功地看到了包含帐户信息的字典数组。
但是,当我尝试使用accounts = JSON.stringify(res.accounts);
console.log('accounts: ' + accounts);
时,我收到错误:
res.json({accounts: accounts})
当我尝试运行
res.json({accounts: accounts});
^
TypeError: undefined is not a function
代替res.json时,我收到同样的错误:
res.send(accounts)
这是我的代码:
res.send({accounts: accounts});
^
TypeError: undefined is not a function
var public_token = "";
var access_token = "";
var accounts = [];
};`
另外,当我运行最后两行时:
app.post('/authenticate', function (req, res) {
console.log('post');
public_token = req.body.public_token;
console.log(public_token);
console.log('plaid: ' + app.client);
server.client.exchangeToken(public_token, function (err, res) {
console.log('exchange');
if (err) {
//Handle Error
console.log('exchange-error');
}
else {
//We now have exchanged our Plaid access token.
//Store it somewhere persistent
//Access token is used to make API calls
access_token = res.access_token;
console.log('access_token: ' + access_token);
server.client.getAuthUser(access_token, function (err, res) {
if (err != null) {
//handle error
console.log('authorization-error');
}
else {
// Our response will hold an array of accounts for this user, containing account names,
// balances, account and routing numbers.
accounts = JSON.stringify(res.accounts);
console.log('accounts: ' + accounts);
//Return account data
res.json({accounts: accounts});
}
});
}
});
res.contentType('application/json');
res.send(accounts);
});
帐户变量的默认值为
res.contentType('application/json');
res.send(accounts);
我认为这可能是一个封闭问题,但我不确定。
答案 0 :(得分:2)
app.post('/authenticate', function (req, res) {
console.log('post');
public_token = req.body.public_token;
console.log(public_token);
console.log('plaid: ' + app.client);
server.client.exchangeToken(public_token, function (err, ***res***) {
你在第二次回调中覆盖了res
