Create an Array of Strings in Node from a URL

问题

我想从以下URL获取文本内容：

https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt

然后创建一个名为httpProxies的数组，其中URL中的每一行代表数组中的一个值。

基本上我想要：

  1. console.log(httpProxies); // 返回 [ '78.110.195.242:7080', '144.86.187.56:8888', '64.225.4.85:9999', '34.146.64.228:3128', ...]

我已经开始使用这段代码：

  1. const getScript = (url) => {
  2.   return new Promise((resolve, reject) => {
  3.     const http = require('http'),
  4.           https = require('https');
  6.     let client = http;
  8.     if (url.toString().indexOf("https") === 0) {
  9.         client = https;
  10.     }
  12.     client.get(url, (resp) => {
  13.         let data = '';
  15.         // 收到数据块。
  16.         resp.on('data', (chunk) => {
  17.             data += chunk;
  18.         });
  20.         // 完整的响应已经接收到。打印结果。
  21.         resp.on('end', () => {
  22.             resolve(data);
  23.         });
  25.     }).on("error", (err) => {
  26.         reject(err);
  27.     });
  28. });
  29. };
  31. (async (url) => {
  32.     console.log(await getScript(url));
  33. })('https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt');

但我不确定如何创建数组。有什么想法吗？

英文:

I want to take the txt contents of this URL:

https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt

And create an array named httpProxies where each line from the URL represents a value in the array.

Basically I want:

  1. console.log(httpProxies); //to return [ '78.110.195.242:7080', '144.86.187.56:8888', '64.225.4.85:9999', '34.146.64.228:3128', ...]

I began using this code:

  1. const getScript = (url) => {
  2.   return new Promise((resolve, reject) => {
  3.     const http      = require('http'),
  4.           https     = require('https');
  6.     let client = http;
  8.     if (url.toString().indexOf("https") === 0) {
  9.         client = https;
  10.     }
  12.     client.get(url, (resp) => {
  13.         let data = '';
  15.         // A chunk of data has been recieved.
  16.         resp.on('data', (chunk) => {
  17.             data += chunk;
  18.         });
  20.         // The whole response has been received. Print out the result.
  21.         resp.on('end', () => {
  22.             resolve(data);
  23.         });
  25.     }).on("error", (err) => {
  26.         reject(err);
  27.     });
  28. });
  29. };
  31. (async (url) => {
  32.     console.log(await getScript(url));
  33. })('https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt');

But I am unsure how to create the array. Any ideas?

以下是翻译好的部分：

  1. 您可以像这样做：
  3. <!-- begin snippet: js hide: false console: true babel: false -->
  5. <!-- language: lang-js -->
  7.     const getScript = async (url) => {
  8.       const response = await fetch(url);
  9.       const data = await response.text();
  10.       return data.split("\n");
  11.     };
  13.     (async () => {
  14.       const httpProxies = await getScript(
  15.         "https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt"
  16.       );
  17.       console.log(httpProxies);
  18.     })();
  20. <!-- end snippet -->
  22. ---
  24. 如果您想知道如何在您的代码中执行此操作，只需执行以下操作 `resolve(data.split('\n'));`
  26. ```js
  27. const getScript = (url) => {
  28.   return new Promise((resolve, reject) => {
  29.     const http = require('http'),
  30.       https = require('https');
  32.     let client = http;
  34.     if (url.toString().indexOf('https') === 0) {
  35.       client = https;
  36.     }
  38.     client
  39.       .get(url, (resp) => {
  40.         let data = '';
  42.         // 收到数据块。
  43.         resp.on('data', (chunk) => {
  44.           data += chunk;
  45.         });
  47.         // 已接收到整个响应。打印结果。
  48.         resp.on('end', () => {
  49.           resolve(data.split('\n')); // 🔈 这里
  50.         });
  51.       })
  52.       .on('error', (err) => {
  53.         reject(err);
  54.       });
  55.   });
  56. };
  58. (async (url) => {
  59.   console.log(await getScript(url));
  60. })(
  61.   'https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt'
  62. );
  2. <details>
  3. <summary>英文:</summary>
  5. You can do something like this:
  7. &lt;!-- begin snippet: js hide: false console: true babel: false --&gt;
  9. &lt;!-- language: lang-js --&gt;
  11.     const getScript = async(url) =&gt; {
  12.       const responce = await fetch(url);
  13.       const data = await responce.text();
  14.       return data.split(&quot;\n&quot;);
  15.     };
  17.     (async() =&gt; {
  18.       const httpProxies = await getScript(
  19.         &quot;https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt&quot;
  20.       );
  21.       console.log(httpProxies);
  22.     })();
  24. &lt;!-- end snippet --&gt;
  27. ---
  29. And if you want to know how to do it with your code then just do this `resolve(data.split(&#39;\n&#39;));`
  31. ```js
  32. const getScript = (url) =&gt; {
  33.   return new Promise((resolve, reject) =&gt; {
  34.     const http = require(&#39;http&#39;),
  35.       https = require(&#39;https&#39;);
  37.     let client = http;
  39.     if (url.toString().indexOf(&#39;https&#39;) === 0) {
  40.       client = https;
  41.     }
  43.     client
  44.       .get(url, (resp) =&gt; {
  45.         let data = &#39;&#39;;
  47.         // A chunk of data has been recieved.
  48.         resp.on(&#39;data&#39;, (chunk) =&gt; {
  49.           data += chunk;
  50.         });
  52.         // The whole response has been received. Print out the result.
  53.         resp.on(&#39;end&#39;, () =&gt; {
  54.           resolve(data.split(&#39;\n&#39;)); // &#128072; This
  55.         });
  56.       })
  57.       .on(&#39;error&#39;, (err) =&gt; {
  58.         reject(err);
  59.       });
  60.   });
  61. };
  63. (async (url) =&gt; {
  64.   console.log(await getScript(url));
  65. })(
  66.   &#39;https://raw.githubusercontent.com/monosans/proxy-list/main/proxies/http.txt&#39;
  67. );
