那是我對API 呼叫的原始回應，我試圖用一個.forEach
const app = express();
const axios = require('axios')
jobList = [];
app.get('/getAPIResponse', function(req, res) {
async function myFunction() {
axios.get('https://api...')
//res.json(body)
.then((result) => {
result.results.forEach((element) => {
console.log(element)
this.jobList.push(element)
});
})
}
myfunction();
});
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`);
});
但問題是，它讓我的終端出現了一些錯誤

盡可能清楚的results是api中的關鍵字，我想從中獲取每個結果塊以插入我的“jobList”
我到處尋找，這forEach似乎是正確的技術......
uj5u.com熱心網友回復：
您正在使用模塊axios
這將回傳帶有axios 回應模式的回應
所以你必須得到這樣的結果result.data.results然后你可以使用forEach函式
uj5u.com熱心網友回復：
采用result.data.results.forEach
