我搜索了如何通过couchdb访问外部Web服务器,但我找不到。
我的网络应用程序存储在couchdb(localhost:5984)上,我的图片(格式为png)是wev服务器上的存储(localhost:5986),用Python运行。
所以,我想通过我的网络应用程序获取我的照片。这是我在“local.ini”文件中对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 = *

访问数据库后,您可能需要考虑构建每个文档附件的URL,如下所示:
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
并使用Jinja2模板:
{% for img in function() %}
<img class="some-class" src="{{ img }}">
{% endfor %}`
