我正在尝试从yahoo finance解析一个非常简单的csv文件。由此产生的csv只有股票的当前价格。当我运行这个时,我继续得到这个错误。我的语法中有什么东西吗?
/ tmp / de49fef0-c2fb-11e6-b1be-07e013ca5c3c / Node Application / app.js:6 https.get(endpoint,(response)=> {^ SyntaxError:意外的令牌> 在Module._compile(module.js:437:25)处于Object.Module._extensions..js (module.js:467:10)在Module.load(module.js:356:32)at Module.runMain中的Function.Module._load(module.js:312:12) (module.js:492:10)at process.startup.processNextTick.process._tickCallback(node.js:244:9)
var https = require('https')
var endpoint = "http://finance.yahoo.com/d/quotes.csv?s=AAPL&f=a"
var body = ""
https.get(endpoint, (response) => {
response.on('data', (chunk) => { body += chunk })
response.on('end', () => {
var data = JSON.parse(body)
console.log(data)})})

我认为这会进行下载。它基于此解决方案,需要重定向处理
How to download a file with Node.js (without using third-party libraries)?
var http = require('http');
var fs = require('fs');
var endpoint = "http://finance.yahoo.com/d/quotes.csv?s=AAPL&f=a"
var body = ""
var download = function(url, dest, cb) {
var file = fs.createWriteStream(dest);
var request = http.get(url, function(response) {
if(response.statusCode === 301){
console.log();
var request = http.get(response.headers.location, function(response) {
response.pipe(file);
file.on('finish', function() {
file.close(cb); // close() is async, call cb after close completes.
});
});
}
}).on('error', function(err) { // Handle errors
fs.unlink(dest); // Delete the file async. (But we don't check the result)
if (cb) cb(err.message);
});
};
download(endpoint, 'test.csv', function(err){
if(err){
console.log(err);
}
else{
//read csv file here
console.log(fs.readFileSync('test.csv').toString());
}
})
