[英]The updateDocument api in the Discovery module of ibm's watson-developer-cloud Node.js sdk insists on a file parameter
[英]Sending an AlchemyData News query using Node.js (watson-developer-cloud module)
我目前正在使用watson-developer-cloud Node.js SDK使用Node.js,在發送包含實體的查詢時遇到問題。
這是我的代碼:
// require watson's node sdk and fs
var watson = require('watson-developer-cloud');
var fs = require('fs');
// Define output file
var outputJSONFile = '/home/vagrant/Desktop/node/dir/data.json';
// Create alchemy_data_news object using our api_key
var alchemy_data_news = watson.alchemy_data_news({
api_key: ''
});
// Define params for the query and what values to return
// Accepted returne values:
// docs.alchemyapi.com/v1.0/docs/full-list-of-supported-news-api-fields
var params = {
start: 'now-1m',
end: 'now',
count: 2,
qs: ['q.enriched.url.enrichedTitle.entities.entity.text=apple'],
return: ['enriched.url.url,enriched.url.title']
};
// Call getNews method and return json
alchemy_data_news.getNews(params, function (err, news) {
if (err) {
console.log('error:', err);
} else {
fs.writeFile(outputJSONFile, JSON.stringify(news, null, 2), function(err) {
if (err) {
console.log('WriteFile Error:', err);
} else {
console.log("JSON saved to " + outputJSONFile);
}
});
}
});
我仍在嘗試找出如何使用params對象發送實體參數。
在研究一些代碼時,我遇到了qs,因此我一直在使用它進行測試,但我一點都沒有成功。
任何建議,不勝感激。
PS:我想通過:
q.enriched.url.enrichedTitle.entities.entity.text = apple q.enriched.url.enrichedTitle.entities.entity.type = company
如果查看AlchemyDataNews的node-sdk源代碼 ,您將看到頂級參數作為查詢字符串發送。
然后params
映射應該是:
var params = {
start: 'now-1m',
end: 'now',
count: 2,
return: ['enriched.url.url,enriched.url.title'],
// fields here
'q.enriched.url.enrichedTitle.entities.entity.text': 'apple',
'q.enriched.url.enrichedTitle.entities.entity.type': 'company'
};
