    【已解决】Python用WordPress的REST接口实现查询已有同名的category目录

    Python crifan 790浏览 0评论
    折腾：
    【已解决】给Python发布印象笔记帖子内容到WordPress文章时加上分类和标签
    期间，希望不要新建，而是给定名字，查到之前已有（最好是唯一的）同名的category目录（和后续的tag标签）
    结果之前已尝试：
    【已解决】Python调用WordPress的REST接口新建Category目录

    此处会，新建一个同名的category，而不是告知已有了。
    哎，不是我希望的结果。
    因为希望是，告知已有，这样就可以：不用新建了。
    不过突然发现：
    Categories | REST API Handbook | WordPress Developer Resources
    其中有个search
    或许可以实现我们要的：通过
    /wp-json/wp/v2/categories
    加上search参数，比如搜mac，返回之前已有的，且唯一的目录，则即可实现：
    判断是否已存在同名的category（和后续的tag）
    去试试
        def searchCategory(self, name):
        """Search wordpress category
            by call REST api: GET /wp-json/wp/v2/categories


        Args:
            name (str): category name to search
        Returns:
            (bool, dict)
                True, found category info
                False, error detail
        Raises:
        """
        curHeaders = {
            "Authorization": self.authorization,
            "Accept": "application/json",
        }
        logging.debug("curHeaders=%s", curHeaders)


        queryDict = {
            "search": name, # 'Mac'
        }


        searchCategoryUrl = self.apiCategories
        resp = requests.get(
            searchCategoryUrl,
            proxies=self.requestsProxies,
            headers=curHeaders,
            data=queryDict,
        )
        logging.info("resp=%s", resp)


        isSearchOk, respInfo = crifanWordpress.processCreateResponse(resp)
        return isSearchOk, respInfo
    调试看看
    {'code': 'jwt_auth_invalid_token', 'message': 'Expired token', 'data': {'status': 403}}
    重新去更新一个jwt的token，再试试
    可以返回了：

    -》竟然里面没有Mac这个关键字。。。
    难道search没生效？？
    看了下，目前是返回了10个category
    “per_page
    Maximum number of items to be returned in result set.
    Default: 10”
    是这个参数决定的。
    wp-json/wp/v2/categories search
    fetching categories with rest APIv2 | WordPress.org
    https://wordpress.org/support/topic/fetching-categories-with-rest-apiv2/
    难道是requests中传递有误，参数没传递进去？
    不是data=queryDict？
    参考：
    payload = {'key1': 'value1', 'key2': 'value2’}
r = requests.get('https://httpbin.org/get', params=payload)
print(r.url)
# https://httpbin.org/get?key2=value2&key1=value1
    果然是写错了。
    改为：
    params=queryDict, # {'search': 'Mac'}
    结果：
    就对了：

    其中
    第二个就是：我们要的：
      "id": 1374,
  "count": 350,
  "description": "",
  "link": "https://www.crifan.com/category/work_and_job/operating_system_and_platform/mac/",
  "name": "Mac",
  "slug": "mac",
    第三个就是我们刚新建的：
      "id": 13223,
  "count": 0,
  "description": "",
  "link": "https://www.crifan.com/category/mac-2/",
  "name": "Mac",
  "slug": "mac-2",
    【总结】
    此处用代码：
        def searchCategory(self, name):
        """Search wordpress category
            by call REST api: GET /wp-json/wp/v2/categories


        Args:
            name (str): category name to search
        Returns:
            (bool, dict)
                True, found category info
                False, error detail
        Raises:
        """
        curHeaders = {
            "Authorization": self.authorization,
            "Accept": "application/json",
        }
        logging.debug("curHeaders=%s", curHeaders)


        queryParamDict = {
            "search": name, # 'Mac'
        }


        searchCategoryUrl = self.apiCategories
        resp = requests.get(
            searchCategoryUrl,
            proxies=self.requestsProxies,
            headers=curHeaders,
            # data=queryDict, # {'search': 'Mac'}
            params=queryParamDict, # {'search': 'Mac'}
        )
        logging.info("resp=%s", resp)

        isSearchOk, respInfo = crifanWordpress.processCreateResponse(resp)
        return isSearchOk, respInfo
    调用：
                firstCategory = categories[0]
            isSearhOk, existedCategoryInfo = self.searchCategory(firstCategory)
            logging.info("isSearhOk=%s, existedCategoryInfo=%s", isSearhOk, existedCategoryInfo)
    是可以返回：我们希望的数据的
    一共9个，其中第二个就是我们要的：
    [{
。。。
}, {
  "id": 1374,
  "count": 350,
  "description": "",
  "link": "https://www.crifan.com/category/work_and_job/operating_system_and_platform/mac/",
  "name": "Mac",
  "slug": "mac",
  "taxonomy": "category",
  "parent": 4624,
  "meta": [],
  "_links": {
    "self": [{
      "href": "https://www.crifan.com/wp-json/wp/v2/categories/1374"
    }],
    "collection": [{
      "href": "https://www.crifan.com/wp-json/wp/v2/categories"
    }],
    "about": [{
      "href": "https://www.crifan.com/wp-json/wp/v2/taxonomies/category"
    }],
    "up": [{
      "embeddable": True,
      "href": "https://www.crifan.com/wp-json/wp/v2/categories/4624"
    }],
    "wp:post_type": [{
      "href": "https://www.crifan.com/wp-json/wp/v2/posts?categories=1374"
    }],
    "curies": [{
      "name": "wp",
      "href": "https://api.w.org/{rel}",
      "templated": True
    }]
  }
}, {
。。。
    即：
    name=Mac，slug=mac
    的category。
    即可供后续使用。
