JSON 模式，oneOf 验证

Question

我的登录端点可以有“社交”登录和“用户”登录，因此正文可以如下所示:

user: {
  email: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c1b5a4b2b581a6aca0a8adefa2aeac" rel="noreferrer noopener nofollow">[email protected]</a>',
  password: 'test'
}

或者像这样:

authentication: {
  provider: 'facebook',
  token: 'abcd'
}

我想创建一个 JSON 架构来验证第一个正文或第二个正文。我偶然发现了 oneOf，这就是我尝试过的:

body: {
        oneOf: [{
          properties: {
            user: {
              type: 'object',
              required: [
                'email',
                'password'
              ],
              email: {
                type: 'string',
                format: 'email'
              },
              password: {
                type: 'string',
                minLength: 6,
                maxLength: 32
              }
            },
          }
        }, {
          properties: {
            authentication: {
              type: 'object',
              required: [
                'provider',
                'token'
              ],
              provider: {
                type: 'string',
                enum: ['facebook']
              },
              token: {
                type: 'string'
              }
            }
          }
        }]
      }

但是这给了我以下错误:

    {
        "keyword": "oneOf",
        "dataPath": ".body",
        "schemaPath": "#/properties/body/oneOf",
        "params": {},
        "message": "should match exactly one schema in oneOf"
    }

如果有人能帮我为此设置 JSON 架构，那就太棒了。谢谢

您可以使用oneOf来做到这一点。尽管我会以不同的方式使用它。

 {
   "$schema": "http://json-schema.org/schema#",
   "type": "object",
   "properties": {
     "login": {
       "oneOf": [
         {
           "required": [
             "user"
           ]
         },
         {
           "required": [
             "authentication"
           ]
         }
       ],
       "type": "object",
       "properties": {
         "user": {
           "type": "object",
           "properties": {
             "email": {
               "type": "string"
             },
             "password": {
               "type": "string"
             }
           }
         },
         "authentication": {
           "type": "object",
           "properties": {
             "email": {
               "type": "string"
             },
             "password": {
               "type": "string"
             }
           }
         }
       }
     }
   }
 }

这样，两个 json 就根据架构进行了验证

 {
   "login": {
     "authentication": {
       "provider": "facebook",
       "token": "abcd"
     }
   }
 } 

 {
   "login": {
     "user": {
       "email": "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="790d1c0a0d391e14181015571a1614" rel="noreferrer noopener nofollow">[email protected]</a>",
       "password": "test"
     }
   }
 }

但是如果你尝试将它们放在一起，它将不会验证

 {
   "login": {
     "authentication": {
       "provider": "facebook",
       "token": "abcd"
     },
     "user": {
       "email": "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="225647515662454f434b4e0c414d4f" rel="noreferrer noopener nofollow">[email protected]</a>",
       "password": "test
     }
   }
 }
