无法从 Twilio API 解析格式错误的 JSON 示例有效负载

如何解决无法从 Twilio API 解析格式错误的 JSON 示例有效负载

我花了 4 个小时试图从 Twilio 解析一个简单的 JSON。

流程是：

1. 包含 magnet 链接的短信
2. Twilio 代理请求我在云上的无服务器功能
3. 解析请求。获取价值

Twilio Studio 用户界面

代码

....
var app = express()
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())

module.exports.magnet = async (event) => {
  let requestBody = ''
  try {
    requestBody = JSON.parse(event.body)
    requestBody = requestBody["magnet"]
  } catch (err) {
    console.error(err)
  }
  await beginAuth(requestBody
....

我刚刚收到格式错误的 JSON。当我同时使用 stringify 和 parse 时，我要么得到格式错误的错误，要么得到一个添加的 \r 转义字符，这也会导致问题。

不确定这只是 Twilio 还是我。我只想要磁力链接作为字符串。

我试过了

JSON.parse(JSON.stringify(event.body))

但这也无济于事。

解决方法

Twilio 发送的正文通常格式为 query string，即您必须像这样对其进行解码：

const querystring = require('querystring');
requestBody = querystring.parse(event.body);
requestBody = requestBody['magnet']

要验证它是否作为查询字符串发送，只需在收到它后打印 event.body，在您的示例中，它应该类似于：

magnet=magnet%3A%3Fxt%3Durn%3Abtih%3A9970E5BF56EDDB06024EF1311109865B893C8EB4%26dn%3DWestworld%2B-%2BSeason%2B3%2B-%2BMp4%2Bx264%2BAC3%2B1080p%26tr%3Dudp%253A%252F%252Ftracker.leechers-paradise.org%253A6969%252Fannounce%26tr%3Dudp%253A%252F%252Ftracker.coppersurfer.tk%253A6969%252Fannounce%26tr%3Dudp%253A%252F%252Ftracker.coppersurfer.tk%253A80%252Fannounce%26tr%3Dudp%253A%252F%252Ftracker.opentrackr.org%253A1337%252Fannounce%26tr%3Dudp%253A%252F%252Ftracker.zer0day.to%253A1337%252Fannounce%26tr%3Dudp%253A%252F%252Ftracker.pirateparty.gr%253A6969%252Fannounce%26tr%3Dudp%253A%252F%252Feddie4.nl%253A6969%252Fannounce%26tr%3Dudp%253A%252F%252Fcoppersurfer.tk%253A6969%252Fannounce%26tr%3Dudp%253A%252F%252Ftracker.leechers-paradise.org%253A6969%26tr%3Dudp%253A%252F%252Ftracker.coppersurfer.tk%253A6969%26tr%3Dudp%253A%252F%252Ftracker.opentrackr.org%253A1337%26tr%3Dudp%253A%252F%252Ftracker.pirateparty.gr%253A6969%26tr%3Dudp%253A%252F%252Feddie4.nl%253A6969%26tr%3Dudp%253A%252F%252Ftracker.coppersurfer.tk%253A80%26tr%3Dudp%253A%252F%252Ftracker.zer0day.to%253A1337%252Fannounce%26tr%3Dudp%253A%252F%252Ftracker.leechers-paradise.org%253A6969%252Fannounce%26tr%3Dudp%253A%252F%252Fcoppersurfer.tk%253A6969%252Fannounce
