我得到错误,找不到函数。 我不明白..是因为https.get中的回调吗? 我想在http请求完成时调用回调函数。http请求中的Nodejs回调函数
const happy = ['happy'];
twitterService.twitter(happy, '1233,1233', '50', function (length) {
console.log(length + " bepedie boopdap");
});
twitter.js
module.exports.twitter = function (hashtags, location, distance, callbackLength) {
if (hashtags.length !== 0) {
let hashURL = createHashtagUrl(hashtags);
const options = {
host: config.apiURL,
path: '/1.1/search/tweets.json?q=' + hashURL + '&geocode=' + location + ',' + distance + 'km&count=100',
method: 'GET',
headers: {
'Authorization': 'Bearer ' + config.base64Token
}
};
https.get(options, function (res) {
let body = '';
res.on('data', function (data) {
body += data;
});
res.on('end', function() {
let jsonObj = JSON.parse(body);
let length = jsonObj.statuses.length;
callbackLength(length); // HERE its says .. is not a function
})
.on('error', function (e) {
console.log("ERROR BEEP BEEP" + e);
});
});
}
};
function createHashtagUrl(hashtags) {
let hashURL = config.hashtagUnicode + hashtags[0];
for (let i = 1; i < hashtags.length; i++)
hashURL += '+OR+' + config.hashtagUnicode + hashtags[i];
return hashURL;
}
任何人的想法?
你肯定对参数你传递twitterService.twitter(快乐, '1233,1233', '50' – KornholioBeavis
是,如果我(5)if语句之前调用callbackLength,它的工作原理量.. –
这是你正在使用的_actual_代码吗? – robertklep
