“无效的主机头”启动Sledleton Web Application for Hyperledger Developer Guide教程

问题描述 投票:0回答:2

我正在通过Hyperledger Developer Guide Tutorial。我已经完成了生成REST API的步骤,没有任何问题。在完成生成您的Skeleton Web应用程序部分之后,我没有看到shell输出中的任何问题,但是当我尝试按照指示导航到端口4200时,我得到一个大多数空白的屏幕,上面写着Invalid Host header

在Rocketchat上的#composer频道中,我看到有人有一个similar problem。有人建议这是:

因为无法创建或访问keyValStore下的hlfv1配置文件中指定的目录。您很可能已指定了一个目录,例如/home/fred/.hfc-key-store,但用户fred不存在,因此目录/ home / fred不存在。一种解决方案就是自己创建目录路径。

我检查了一下,我的目录没问题:

ibmadmin@pfuntner1:~/repos$ cat /home/ibmadmin/.composer-connection-profiles/hlfv1/connection.json
{
    "type": "hlfv1",
    "orderers": [
       { "url" : "grpc://localhost:7050" }
    ],
    "ca": { "url": "http://localhost:7054",
            "name": "ca.org1.example.com"
    },
    "peers": [
        {
            "requestURL": "grpc://localhost:7051",
            "eventURL": "grpc://localhost:7053"
        }
    ],
    "keyValStore": "/home/ibmadmin/.composer-credentials",
    "channel": "composerchannel",
    "mspID": "Org1MSP",
    "timeout": "300"
}
ibmadmin@pfuntner1:~/repos$ ls -ld /home/ibmadmin/.composer-credentials
drwxrwxr-x 2 ibmadmin ibmadmin 4096 Sep 13 15:11 /home/ibmadmin/.composer-credentials

有没有人有什么建议?

Update

我补充说:

这似乎与webpack有关,虽然我自己没有看到这个问题。

例如https://support.glitch.com/t/invalid-host-header/1413

我能够通过用我的实际IP地址替换package.json中的0.0.0.0主机参数来解决这个问题。它位于package.json文件的scripts部分:

"scripts": {
  "ng": "ng",
  "build": "ng build",
  "prepack": "npm run build",
  "start": "ng serve --proxy-config proxy.conf.js --host 0.0.0.0",
  ...

更改此项并运行“npm start”后,可以从远程主机访问端口4200。
