[英]Execute HTTP request to an external server when any CouchDB Data changes
[英]Access external web server couchdb
我搜索如何通過Couchdb訪問外部Web服務器,但找不到。
我的Web應用程序存儲在couchdb(localhost:5984)上,我的圖片(格式png)存儲在使用Python運行的wev服務器(localhost:5986)上。
因此,我想通過Web應用程序獲取圖片。 這是我在文件“ local.ini”中對couchdb的配置:
[httpd_global_handlers]
_maps = { couch_httpd_proxy, handle_utils_dir_req, "<< localhost:5986 >> " }
[httpd]
enable_cors = true
allow_jsonp = true
[cors]
origins = *
訪問數據庫后,您可能需要考慮如下構建每個文檔附件的url:
def function():
couch = couchdb.Server() #connect to server
db = couch['img'] #connect to database which contains docs with img attachments
doc_id = [] #create list of id's
http_docid = [] #create list to populate href for picture path
for i in db: #for each id in the db
doc_id.append(i) #add to the carid list
doc = db[i] #get the document id
for key in (doc['_attachments']): #for the key in the doc '_attacments' payload
print key #just to confirm
href_docid.append(('http://yourdbDomain/dbname/'+i+'/'+key)) #create a uri and append to a list
return href_docid
並使用Jinja2模板:
{% for img in function() %}
<img class="some-class" src="{{ img }}">
{% endfor %}`
