python - 正确完成所有操作后出现 Ngrok 错误 6022

Question

详情可以引用我的图片。 这是我在 colab 上运行的代码:

from google.colab import drive
drive.mount('/content/drive')

cd /content/drive/MyDrive/mini

!curl -s https://ngrok-agent.s3.amazonaws.com/ngrok.asc | sudo tee 
/etc/apt/trusted.gpg.d/ngrok.asc >/dev/null && echo "deb https://ngrok-agent.s3.amazonaws.com 
buster main" | sudo tee /etc/apt/sources.list.d/ngrok.list && sudo apt update && sudo apt 
install ngrok

!ngrok authtoken "I added my auth token here"

from pyngrok import ngrok
from flask_ngrok import run_with_ngrok
from flask import Flask, render_template
app = Flask(__name__)
run_with_ngrok(app)
@app.route('/')
def text():
  return f"Running Flask on Google Colab"

app.run()

获取此输出:

 * Serving Flask app "__main__" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off

127.0.0.1 - - [17/Apr/2022 09:03:32] "GET /favicon.ico HTTP/1.1" 404 -

当我点击 ngrok 链接时，即 http://de4b-35-230-126-117.ngrok.io这个给了我这个。

ERR_NGROK_6022
Before you can serve HTML content, you must sign up for a free ngrok account and install your 
authtoken.

所以谁能告诉我我做错了什么？因为我也在 colab 中安装了 ngrok 并安装了 auth token 但仍然出现此错误。

Answer 1

我遇到了同样的问题，ngrok 已更新到 v3，您可以使用 pyngrok 或更新您的代码

解决方案 1: 删除 curl 命令，并改为添加: !pip 安装 pyngrok==4.1.1

解决方案 2: 按照新文档更新绑定(bind) authtoken 的方法 https://ngrok.com/docs/guides/upgrade-v2-v3
