【问题描述】：

我正在尝试根据 ACF 属性查询 Worpress API。

如果我不包含查询，我会得到以下输出：

[{"id":215,"date":"2018-08-05T09:21:37","date_gmt":"2018-08-5T08:21:37","guid":{"rendered":"x"},"modified":"2018-08-05T09:21:37",
"modified_gmt":"2018-08-05T08:21:37","slug":"sasradisson","status":"publish","type":"hotel","link":"https:x",
"title":{"rendered":"SAS Radisson"},"template":"","acf":{"stad":{"value":"barcelona","label":"barcelona"},
"description":"","images":false},"_links":{"self":[{"href":"x"}],"collection":[{"href":"x"}],
"about":[{"href":"x"}],"wp:attachment":[{"href":"x"}],"curies":[{"name":"wp","href":"x","templated":true}]}},
{"id":205,"date":"2018-08-04T11:25:35","date_gmt":"2018-08-04T10:25:35","guid":{"rendered":"x"},
"modified":"2018-08-04T14:22:12","modified_gmt":"2018-08-04T13:22:12","slug":"citybox-oslo","status":"publish",
"type":"hotel","link":"x","title":{"rendered":"Citybox Oslo"},"template":"",
"acf":{"stad":{"value":"oslo","label":"oslo"},"description":"","images":false},
"_links":{"self":[{"href":"x"}],"collection":[{"x"}],"about":[{"href":"x"}],"wp:attachment":[{"href":"x"}],
"curies":[{"name":"wp","href":"x","templated":true}]}}]

（为简洁起见，我将所有网址都替换为“x”）

在所有其他属性中，还有 ACF 属性，如下所示：

"acf":{"stad":{"value":"barcelona","label":"barcelona"}

这些查询都不起作用：

/wp-json/wp/v2/hotels?acf={stad:{value:%27barcelona%27}}

/wp-json/wp/v2/hotels?acf.stad.value=barcelona

如何构建正确的 URL 查询？

如果这不可能，有什么替代解决方案？

【解决方案1】：

我相信通过 post meta 过滤 API 请求是不可能的。因为最后，“按 ACF 值过滤”（至少在帖子上）等于“按帖子元过滤”。

为此，您需要为自己的查询创建自己的 REST 处理程序。一个关于“向 Wordpress API 添加新路由”的快速 Google 搜索将提供很多示例，例如 this one。

看看 ACF（高级自定义字段）插件 + ACF-TO-REST-API 插件：
