错误：[HPM]无效上下文。期待这样的东西："/api“或["/api"，"/ajax"]

Question

从现在起，我得到了以下错误，而我没有改变我的角7项目的任何东西。直到昨天它还没有犯这个错误。

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"
}

}

这条错误信息背后的原因是什么。如何删除此错误。请帮帮忙。

Answer 1

/*不是有效的语法。对于代理所有请求，我们可以使用/或通配符**，如http-proxy-middleware中所述。

Answer 2

在我的例子中，错误是由context中的“普通”路径和通配符路径混合造成的。

无效

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

有效

注：/**在/upload之后删除

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