我试图进一步扩展电报-rocket.chat桥,并为此调用一些apis。为此,rocket.chat公开了一个名为Meteor.js的Meteor.js包装器。
这个代码片段是一个传出钩子,它处理用户发送的消息,让我转换消息并传递修改后的文本。
Prepare_outgoing_request({ rocket.chat })由rocket.chat钩子调用,我想在其中调用一个API,它将表情符号代码解析为实际的表情符号字符:":see_no_evil: to“。
/** Global Helpers
*
* console - A normal console instance
* _ - An underscore instance
* s - An underscore string instance
* HTTP - The Meteor HTTP object to do sync http calls
* https://docs.meteor.com/api/http.html
*/
class Script {
request_emojitext(emoji_code) {
console.log(`called: request_emojitext('${emoji_code}')`);
const url = `https://www.emojidex.com/api/v1/emoji/${emoji_code}`;
const response = HTTP.call('GET', url);
console.log(`Emoji Response: ${response.constructor.name} => ${JSON.stringify(response)}`);
// Emoji Response: Object => {"error":{}}
return response;
}
/**
request.params {object}
request.method {string}
request.url {string}
request.headers {object}
*/
prepare_outgoing_request({ request }) {
const emojiResponse = this.request_emojitext('see_no_evil');
const emojiCharacter = emojiResponse.content.emoji;
return {
// https://core.telegram.org/bots/api
url: `${request.url}&text=${emojiCharacter}`,
method: 'GET'
};
}
}
流星文献指出:
// Asynchronous call
Meteor.call('foo', 1, 2, (error, result) => { ... });
// Synchronous call
const result = Meteor.call('foo', 1, 2);
/*
On the client, if you do not pass a callback and you are not
inside a stub, call will return undefined, and you will have
no way to get the return value of the method. That is because
the client doesn’t have fibers, so there is not actually any
way it can block on the remote execution of a method.
*/
我不知道如何在这里进行,因为我还不完全适应异步编程。我如何阻止,直到结果是实际可用的,或者有一种不同的方式做这件事,我完全错过了?
