折腾：
【未解决】Python用WordPress的REST接口实现查到之前同名的category目录和tag标签
期间，先去看看用Python调用Wordpress的REST的api，去新建目录分类category
找到之前的接口说明：
“categories
array
The terms assigned to the object in the category taxonomy.
Context: view, edit
tags
array
The terms assigned to the object in the post_tag taxonomy.
Context: view, edit“
看了下，貌似是：
没有直接从 name 去查询是否存在的接口
只能通过接口去 list all的category/tag
然后对于返回的所有的category/tag，通过name对比
如果name有相同，则得到对应id
否则就调用post 去新建
突然想到，要不要直接去
POST /wp/v2/tags
看看返回的是啥
如果返回已存在的tag
那么就不用列出所有，这么麻烦了。去试试
去试试
此处调试之前，先去看看此处WordPress后台已有的tag：
->
tag_ID=8123
POST /wp/v2/categories
写代码：
# https://developer.wordpress.org/rest-api/reference/categories/#create-a-category
self.apiCategories = self.host + "/wp-json/wp/v2/categories" # 'https://www.crifan.com/wp-json/wp/v2/categories'
def createCategory(self, name, parent=None, slug=None, description=None):
"""Create wordpress category

Args:

curHeaders = {
"Authorization": self.authorization,
"Content-Type": "application/json",
"Accept": "application/json",
}
logging.info("curHeaders=%s", curHeaders)
#
postDict = {
"name": name, #
}
if parent:
postDict["parent"] = parent
if slug:
postDict["slug"] = slug
if description:
postDict["description"] = description
logging.info("postDict=%s", postDict)
#
createCategoryUrl = self.apiCategories
resp = requests.post(
createCategoryUrl,
proxies=self.requestsProxies,
headers=curHeaders,
json=postDict,
)
logging.info("resp=%s", resp)
isUploadOk, respInfo = crifanWordpress.processCreateResponse(resp)
return isUploadOk, respInfo去调试
先去创建 Mac
此处返回201，是我们希望看到的
-》如果没有，新建，返回200
如果已有，返回201
不对，是201=Created，新创建了
'{"id":13222,"count":0,"description":"","link":"https:\\/\\/www.crifan.com\\/category\\/mac\\/","name":"Mac","slug":"mac","taxonomy":"category","parent":0,"meta":[],"_links":{"self":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/categories\\/13222"}],"collection":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/categories"}],"about":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/taxonomies\\/category"}],"wp:post_type":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/posts?categories=13222"}],"curies":[{"name":"wp","href":"https:\\/\\/api.w.org\\/{rel}","templated":true}]}}'是新建了一个分类category
那去WordPress后台看看，是否多出一个，同名的Mac分类
红色：之前已有的，name=Mac，slug=os_mac，已有305个帖子了
绿色：刚新建的，name=Mac，slug=mac（看来就是针对于原先name的小写，不知道中文时，如何处理），已有帖子0个
-》从逻辑上来说，代码这么自动处理，是没问题的。
不过，为了测试和已有的标签的name和slug都相同，则：
删除刚创建的
name=Mac，slug=mac
且去把已有的
name=Mac，slug=os_mac
改为：
name=Mac，slug=mac
且复制编辑的链接是：
-》得知：tag_ID=1374
然后重新调用一次代码，看看会不会冲突，报错，或者说已存在
还是新建了一个：
'{"id":13223,"count":0,"description":"","link":"https:\\/\\/www.crifan.com\\/category\\/mac-2\\/","name":"Mac","slug":"mac-2","taxonomy":"category","parent":0,"meta":[],"_links":{"self":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/categories\\/13223"}],"collection":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/categories"}],"about":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/taxonomies\\/category"}],"wp:post_type":[{"href":"https:\\/\\/www.crifan.com\\/wp-json\\/wp\\/v2\\/posts?categories=13223"}],"curies":[{"name":"wp","href":"https:\\/\\/api.w.org\\/{rel}","templated":true}]}}'
很明显，此处会：
直接新建一个。。。slug是xxx_2
【总结】
至此，用代码
# https://developer.wordpress.org/rest-api/reference/categories/#create-a-category
self.apiCategories = self.host + "/wp-json/wp/v2/categories" # 'https://www.crifan.com/wp-json/wp/v2/categories'

curHeaders = {
"Authorization": self.authorization,
"Content-Type": "application/json",
"Accept": "application/json",
}
logging.debug("curHeaders=%s", curHeaders)
# curHeaders={'Authorization': 'Bearer eyJxx9.eyJpc3Mxxx19fQ.5IwxxLm-6Yxxx5s', 'Content-Type': 'application/json', 'Accept': 'application/json'}
postDict = {
"name": name, #

if parent:
postDict["parent"] = parent

createCategoryUrl = self.apiCategories
resp = requests.post(
createCategoryUrl,

headers=curHeaders,
json=postDict,
)
logging.info("resp=%s", resp)
isUploadOk, respInfo = crifanWordpress.processCreateResponse(resp)
return isUploadOk, respInfo是可以用于新建category的。
注意：
如果之前已有一个category的name（和slug）
则：新建时，即使name相同，也会重新创建一个的（slug=xxx_2）
返回的结果是：
{

"count": 0,
"description": "",
"link": "https://www.crifan.com/category/mac-2/",
"name": "Mac",
"slug": "mac-2",
