错误：[HPM] 上下文无效。期望类似：“/api”或[“/api”，“/ajax”]

Question

当我没有更改 Angular 7 项目中的任何内容时，我从现在开始收到以下错误。直到昨天才出现这个错误。

Error: [HPM] Invalid context. Expecting something like: "/api" or ["/api", "/ajax"]

这是我的 proxy.config.json

{
"/*": {
    "target": "http://localhost:8088",
    "secure": false,
    "changeOrigin": true,
    "logLevel": "debug"
}

}

此错误消息背后的原因是什么。我怎样才能消除这个错误。请帮忙。

Answer 1

/*语法无效。为了代理所有请求，我们可以使用例如或中所述的/通配符**http-proxy-middleware

Answer 2

就我而言，错误是由混合“正常”路径和通配符路径引起的context

无效的

const PROXY_CONFIG = [
  {
    context: ['/api', '/upload/**'],
    target: 'http://localhost:3000',
    secure: false,
    logLevel: 'debug'
  }
];

有效
注释：/**删除后/upload

const PROXY_CONFIG = [
  {
    context: ['/api', '/upload'],
    target: 'http://localhost:3000',
    secure: false,
    logLevel: 'debug'
  }
];
