一段时间以来，我一直在尝试生成开放徽章，但到目前为止，它们都不会使用在线工具进行验证或烘焙。

我尝试了各种不同的组合。这是我目前正在使用的一个（由于是预生产站点而被删除的站点）：

在http://example.org/badge/5ab0d10a6a02f的网站上：

{
    "@context":"https://w3id.org/openbadges/v1",
    "type":"Assertion",
    "id":"http://example.org/badge/5ab0d10a6a02f",
    "uid":"5ab0d10a6a02f",
    "recipient":
    {
        "type":"email",
        "identity":"email@example.org",
        "hashed":false
    },
    "issuedOn":1521564293,
    "badge":"http://example.org/badge-class.json",
    "verify":
    {
        "type":"hosted",
        "url":"http://example.org/badge-issuer.json"
    }
}

在http://example.org/badge-class.json的网站上：

{
    "@context": "https://w3id.org/openbadges/v1",
    "id": "http://example.org/badge-class.json",
    "type": "BadgeClass",
    "name": "Badge",
    "description": "Description",
    "image": "http://example.org/badge.png",
    "criteria": "http://example.org/criteria",
    "issuer": "http://example.org/badge-issuer.json"
}

在http://example.org/badge-issuer.json：

{
    "@context": "https://w3id.org/openbadges/v1",
    "id": "http://example.org/badge-issuer.json",
    "type": "Issuer",
    "name": "Name",
    "url": "http://www.example.org/",
    "telephone" : "xxxxxxxxx",
    "description" : "description",
    "image" : "http://www.example.org/logo.png",
    "email" : "email@example.org"
}

正确托管在真实站点上后，我尝试对其进行验证和烘焙，但出现以下错误：

对于验证器：

使用面包师：

Could not parse json: Unexpected token <

使用面包师 API：

{
    "message":"could not get assertion: invalid JSON",
    "stack":"Error: could not get assertion: invalid JSON
        at makeError (/app/lib/analyze-assertion.js:6:26)
        at Request._callback (/app/lib/analyze-assertion.js:31:23)
        at Request.self.callback (/app/node_modules/request/request.js:187:22)
        at Request.emit (events.js:98:17)
        at Request.<anonymous> (/app/node_modules/request/request.js:1126:10)

        at IncomingMessage.emit (events.js:117:20)
        at _stream_readable.js:944:16",
    "code":"parse"
}

该徽章的哪一部分导致了问题？

也许http://example.org/badge/5ab0d10a6a02f上的徽章断言文件的最后八 (8) 行应该是：

{

    ...
    ... 
    "badge":"http://example.org/badge-class.json",
    "issuer":"http://example.org/badge-issuer.json",
    "verify":
    {
        "type":"hosted",
        "url":"http://example.org/badge/5ab0d10a6a02f/THIS-BADGE-ASSERTION-FILE.json"
    }
}

THIS-BADGE-ASSERTION-FILE.json标记断言文件在哪里JSON，并且正是我们正在修改其内容的文件。也就是说，“验证”URL 应该指向徽章声明JSON文件（位于文件夹http://example.org/badge/5ab0d10a6a02f/中），而不是指向badge-issuer.json徽章颁发者文件的JSON文件。
