是否可以缓存python suds客户端？ [英] Is it possible to cache a python suds client?

问题描述

我目前正在针对wsdl文件及其对应的50多个xsd文件运行python suds。以下对 Client 的调用大约需要90秒：

 来自肥皂水。客户端导入客户端
 url ='http：// localhost：7080 / webservices / WebServiceTestBean？wsdl'
客户端=客户端（url）
  

运行上面的最后一行后，得到一个 Client 实例。创建该客户端需要很长时间。缓存是否适用于Python对象，还是仅限于诸如字符串和整数之类的基元？

这是我想在代码中执行的操作，语法是错误的，但是它传达了我想要的内容：

<$从suds.client导入p $ p> 客户端


如果'current_client'在缓存中：
client = cache.get（'current_client'）
else：
url ='http：// localhost：7080 / webservices / WebServiceTestBean？wsdl'
client = Client（url）
cache.put（'current_client'，client）


解决方案

suds默认情况下每天会缓存WSDL和XSD文件一天，这样，Client对象的每个实例都不需要单独的URL请求。

90秒似乎是很长的时间，这是花在等待wsdl响应上的时间，还是花在解析wsdl上？如果解析需要花费很长时间，则内置缓存不会有太大帮助。

我以前做过类似的事情，但不是单例模式，我只是使用了模块级全局字典。这是没有所有类杂音的单例模式。

类似这样的事情：

  from suds.client import客户端
 
 _clients = {} 
 
 def get_client（name）：
如果名称不在_clients中：
 _clients [name] =客户端（url_for_name）
 return _clients [name] 
  

I'm currently running python suds against a wsdl file and its corresponding 50+ xsd files. The following call to Client takes about 90 seconds:

from suds.client import Client
url = 'http://localhost:7080/webservices/WebServiceTestBean?wsdl'
client = Client(url)

After I run the last line above, I get a Client instance. Creating that client takes a long time. Does caching work with Python objects or is it restricted to primitives like strings and integers?

Here's what I want to do in code, the syntax is wrong but it's to convey what I want:

from suds.client import Client


if 'current_client' in cache:
    client = cache.get('current_client')
else:
    url = 'http://localhost:7080/webservices/WebServiceTestBean?wsdl'
    client = Client(url)
    cache.put('current_client', client)

解决方案

suds caches WSDL and XSD files for a day by default so that each instantiation of a Client object doesn't require a separate URL request.

90 seconds seems like a really long time, is that time spent waiting on the wsdl response, or is it spent parsing the wsdl? If it's taking that long to parse it, the built-in caching isn't going to help much.

I've done something like this before, but instead of the singleton pattern, I just used a module-level global dictionary. It's the singleton pattern without all the class noise.

Something like this:

from suds.client import Client

_clients = {}

def get_client(name):
    if name not in _clients:
        _clients[name] = Client(url_for_name)
    return _clients[name]
