嗨，我今天刚刚开始学习Node.js和javascript。我试图从一个url获取数据，然后尝试用json解析数据，但我一直得到一个错误。
错误:
(node:25889) UnhandledPromiseRejectionWarning: SyntaxError: Unexpected token v in JSON at position 0
我正试图从下面的html中获取可变游戏的数据，希望有人能帮我弄清楚为什么我不能让它工作？
html代码不是我的，我试图从一个我不控制的站点获取数据。
页面HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Document Title</title>
</head>
<body>
<div id="hud-div">
<p>Welcome to the blah blah blah blah text here</p>
</div>
<script>
var game = new Game({
stage: "prod",
servers: {
v32306117: {
id: "v32306117",
region: "region 1",
name: "region #1",
hostname: "hostname1",
port: 80,
fallbackPort: 8000,
population: 97,
selected: false
},
v32306125: {
id: "v32306125",
region: "region 2",
name: "region #2",
hostname: "hostname2",
port: 80,
fallbackPort: 8000,
population: 38,
selected: false
}
},
userGroup: 0
});
game.init(function() {
game.assetManager.load([{
"name": "\/asset\/image\/map\/grass.png",
"url": "\/asset\/image\/map\/grass.png"
}]);
game.debug.init();
game.run();
});
</script>
</body>
</html>
提取函数:
const fetch = require("node-fetch");
let servers;
async function getServers() {
try {
fetch("https://SiteUrl.com").then(data =>
data.text().then(text =>
text.substring(
text.lastIndexOf("var game ="),
text.lastIndexOf("game.init") - 10
))
).then(res => servers = JSON.parse(res));
} catch (error) {
console.error(error);
}
}
getServers();
对不起，我的英语不是很好
您在代码中出现语法错误
const fetch = require("node-fetch");
let servers;
async function getServers() {
try {
fetch("https://quote-garden.herokuapp.com/api/v2/quotes/random").then(data => {
console.log(data)
}
).then(res => servers = JSON.parse(res));
} catch (error) {
console.error(error);
}
}
(async () => {
const data = await getServers();
console.log(data);
})()
这里我做了一些改动
first The后面缺少{}方括号
