我使用node来调用drafter以生成应用程序的json模式。我的目标是摆脱起草人吐出的所有额外输出。我最终得到了一个巨大的json，但我只需要它的一小部分。
这就是输出：

以下位是我需要的。
content = {
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"question": {
"type": "string"
},
"published_at": {
"type": "string"
},
"url": {
"type": "string"
},
"choices": {
"type": "array"
}
},
"required": [
"question",
"published_at",
"url",
"choices"
]
}
这是我现在的代码，它不像我想象的那样工作。如果您需要更多信息来帮助我，请询问。
App.js
var fs = require('fs');
var edit = require('string-editor');
var lodash = require('lodash');
var _ = require('underscore');
const util = require('util');
const exec = require('child_process').exec;
exec('drafter -f json test.apib' , function(error, stdout, stderr) {
const json = JSON.parse(stdout);
//console.log(json)
var res
function loopThrough(obj){
for(var key in obj){
if(!obj.hasOwnProperty(key)) continue;
if(typeof obj[key] !== 'object'){
//if (cond) var x = {'$schema': };
//if (_.hasIn(obj, '$schema')) {
res = res + "\n" + (key+" = "+obj[key]);
//}
} else {
loopThrough(obj[key]);
}
}
}
loopThrough(json);
//parse = JSON.parse(test);
//string = JSON.stringify(test, null, ' ');
//string = string.replace(/\\n/g, '');
fs.writeFile('test.json', res, function(err) {
if(err) {
return console.log(err);
}
console.log("The file was saved!");
});
if (error !== null) {
console.log('exec error: ' + error);
}
});
这是我要承担的输出。

答案 0 :(得分：1)
您可以尝试通过在线JSON模式生成工具运行它，如下所示：http://jsonschema.net/#/
您还需要考虑在此处阅读建议的JSON模式规范：http://json-schema.org/documentation.html
更新：如果您希望通过Node在运行时生成架构，则可以使用json-schema-generator之类的模块。
再次更新：我不确定是否关注您，但是，通过查看您的数据，您应该能够使用以下内容获取contentType application/schema+json的所有内容1}}像这样：
var _ = require('lodash');
var schemas = [];
function isSchemaType(contentItem) {
return _.get(contentItem, 'attributes.contentType') == 'application/schema+json';
}
function parseContent(content) {
if (_.isObject(content) && _.isArray(content.content)) {
_.forEach(content.content, parseContent);
} else if (isSchemaType(content)) {
schemas.push(JSON.parse(content.content));
}
}
parseContent(jsonData);
console.log(schemas);
