Javascript将对象字符串数组解析为对象中的对象

Question

我正在使用一个第三方应用程序，该应用程序需要特定的数据结构来过滤结果集。我很难弄清楚如何解析它，因为最终结果不是一个传统的对象数组。

有一个函数可以从数组中获取ID列表，并将其转换为对象字符串：

功能：

// Input for articles is an array of IDs
// articles = ['kA10W000001UK2KSAW', 'kA1d0000000DB1CCAW', 'kA1d0000000DAsOCAW']
function createExclusion(articles){
let results = [];
articles.forEach(element => {
results.push(`"EqualsTo": {"Key": "sf_KnowledgeArticleId","Value": {"StringValue":"${element}"}}`)
})
return result;
}

输入数据：

let data = [
'"EqualsTo":{"Key":"sf_KnowledgeArticleId","Value":{"StringValue":"kA10W000001UK2KSAW"}},',
'"EqualsTo":{"Key":"sf_KnowledgeArticleId","Value":{"StringValue":"kA1d0000000DB1CCAW"}},',
'"EqualsTo":{"Key":"sf_KnowledgeArticleId","Value":{"StringValue":"kA1d0000000DAsOCAW"}}'
]

期望的最终结果：

{
IndexId: 1,
PageSize: 2,
PageNumber: 3,
RequestedDocumentAttributes: ["_source_uri", "sf_ArticleNumber", "sf_KnowledgeArticleId"],
AttributeFilter: {
"NotFilter": {
"EqualsTo": {
"Key": "sf_KnowledgeArticleId",
"Value": {
"StringValue": "kA10W000001UK2KSAW"
}
},
"EqualsTo": {
"Key": "sf_KnowledgeArticleId",
"Value": {
"StringValue": "kA1d0000000DB1CCAW"
}
},
"EqualsTo": {
"Key": "sf_KnowledgeArticleId",
"Value": {
"StringValue": "kA1d0000000DAsOCAW"
}
},
},
SortingConfiguration: {
"DocumentAttributeKey": "_document_title",
"SortOrder": "ASC"
}
};
}

我正在尝试通过获取字符串数组并将其解析为正确的形式，在最终结果中重新创建AttributeFilter数据

示例：我试图让它与JSON.parse()一起工作，但数据的格式不正确。

在调整createExclusion函数或以现有形式轻松解析它之间，我如何将对象字符串列表转换为所需最终结果中的对象？

function parse(data) {
return {
IndexId: 1,
PageSize: 2,
PageNumber: 3,
RequestedDocumentAttributes: ["_source_uri", "sf_ArticleNumber", "sf_KnowledgeArticleId"],
AttributeFilter: {
"NotFilter": ? // Parse data here
},
SortingConfiguration: {
"DocumentAttributeKey": "_document_title",
"SortOrder": "ASC"
}
};
}

Answer 1

首先，在JSON:中不能有具有重复键的对象

{
"NotFilter": {
"EqualsTo": {
"Key": "sf_KnowledgeArticleId",
"Value": {
"StringValue": "kA10W000001UK2KSAW"
}
},
"EqualsTo": {
"Key": "sf_KnowledgeArticleId",
"Value": {
"StringValue": "kA1d0000000DB1CCAW"
}
},
"EqualsTo": {
"Key": "sf_KnowledgeArticleId",
"Value": {
"StringValue": "kA1d0000000DAsOCAW"
}
}
}
}

您的NotFilter值应该是一个对象数组。

解析JSON

在调用JSON.parse之前，您的JSON应该是有效的。请确保删除任何尾随逗号，并用大括号将每一行括起来。

let data = [
'"EqualsTo":{"Key":"sf_KnowledgeArticleId","Value":{"StringValue":"kA10W000001UK2KSAW"}},',
'"EqualsTo":{"Key":"sf_KnowledgeArticleId","Value":{"StringValue":"kA1d0000000DB1CCAW"}},',
'"EqualsTo":{"Key":"sf_KnowledgeArticleId","Value":{"StringValue":"kA1d0000000DAsOCAW"}}'
]
const parsed = data.map(item => JSON.parse(`{${item.replace(/,$/, '')}}`));
console.log(parsed);
