Soaplib連接-msg's0：FunctionName'，未找到

Question

我的解決方案存在問題，該解決方案工作得非常好，突然停下來了。 我編寫了服務器/客戶端腳本和模塊來為我的應用程序創建SOAP連接類型。 這是我的服務器代碼：

import os
import rsglobal
import signal
import soaplib
from soaplib.core.service import rpc, DefinitionBase, soap
from soaplib.core.model.primitive import String, Integer
from soaplib.core.server import wsgi
from soaplib.core.model.clazz import Array

try:
    import psycopg
except:
    import psycopg2 as psycopg

import rssql

LogFile = "serwer_soap.log"

        results = []
        for i in range(0,times):
            results.append('Hello, %s'%name)
        return results

    @soap(String,String,_returns=String)
    def ConnectToBase(self,name,passwd):
        global PolSQL
        try:
            stat = 'OK'
            dane=[]
            PolSQL=rssql.RSSQL()

            if PolSQL.ConnectToSQL(name,passwd,'127.0.0.1',5432,'','databasename')==1:
                stat = u'Connection Error'

            SQL='SELECT * FROM table1;'
            stat,dane,dump,dump=PolSQL.Execute(SQL,3)
        except Exception,e:

        return stat+' '+str(dane)

我的客戶端代碼（僅測試服務器）如​​下所示：

from suds.client import Client

hello_client = Client('http://128.1.2.3:1234/AnakondaSOAPServer?wsdl')

hello_client.options.cache.clear()

result = hello_client.service.ConnectToBase("username", "password")
print 'Result1',result
result = hello_client.service.GiveData()
print 'Result2',result

在我的主應用程序中，我先前使用帶有適當參數的功能StartSOAPServer，並且它正在等待連接。 我可以用netstat在良好的地址和端口上看到它。

運行客戶端腳本后，我得到：

Traceback (most recent call last):
  File "./testsoapclient.py", line 8, in <module>
    hello_client = Client('http://128.1.2.3:1234/AnakondaSOAPServer?wsdl')
  File "/usr/local/lib/python2.6/dist-packages/suds-0.4-py2.6.egg/suds/client.py", line 112, in __init__
    self.wsdl = reader.open(url)
  File "/usr/local/lib/python2.6/dist-packages/suds-0.4-py2.6.egg/suds/reader.py", line 152, in open
    d = self.fn(url, self.options)
  File "/usr/local/lib/python2.6/dist-packages/suds-0.4-py2.6.egg/suds/wsdl.py", line 158, in __init__
    self.resolve()
  File "/usr/local/lib/python2.6/dist-packages/suds-0.4-py2.6.egg/suds/wsdl.py", line 207, in resolve
    c.resolve(self)
  File "/usr/local/lib/python2.6/dist-packages/suds-0.4-py2.6.egg/suds/wsdl.py", line 494, in resolve
    raise Exception("msg '%s', not-found" % op.input)
Exception: msg 's0:ConnectToBase', not-found

早些時候，在創建SOAP連接后，我對功能的可見性存在疑問。 解決的辦法是清除緩存。 現在我什至無法創建它。 我使用python 2.6，最近我的主應用程序從2.4轉移到2.6。 這是我能想到的唯一區別。

我嘗試用soaplib.core.Application定義進行操作，但是沒有用。

請幫忙 ：）

Answer 1

我設法克服了這些問題，並且它再次起作用。 修復情況的第一件事是將服務器分為兩類-一類用於創建對象並運行SOAPServer，第二類-SOAPServer僅包含功能定義。

即使進行了此更改，我也有不好的結果。 我發現，服務器定義的損壞結構隱藏在/ tmp / suds目錄中（這就是為什么它之前損壞代碼時仍在工作的原因）。 刪除此文件可以刷新此結構，並且所有腳本都可以再次開始工作。
