我尝试与 otrs-ticketsystem 交互，以便 几张图片并计算一些统计数据。这是我想在 haskell 中做的 - 我 使用包 soap .

忽略导入语句，代码相当简单，我创建了一个 带有配置文件 soap.cfg 的 SOAP-Transport(见下文)。然后构建 SOAP-Body 并使用 "Dispatch" 调用 Web 服务。

{-# LANGUAGE OverloadedStrings #-}

import Network (withSocketsDo)
import Network.SOAP
import Network.SOAP.Transport.HTTP

import Text.XML.Writer
import Text.XML.Stream.Parse as Parse
import           Data.Text (Text)
import qualified Data.Text as T
import qualified Data.ByteString.Lazy.Char8 as BS
import Data.Configurator (load, Worth(Required))

main :: IO ()
main = withSocketsDo $ do
    transport <- confTransport "soap" =<< load [Required "./src/SOAP/soap.cfg"]
    let body = do element "TicketObject" ("TicketSearch" :: Text)
                  element "OwnerID" ("owner" :: Text)

    xmlresult <- invokeWS transport "#TicketObject" () body (RawParser id)
    BS.putStrLn xmlresult

soap.cfg

soap {
    url = "http://domain/otrs/rpc.pl"
    user = "testuser"
    password = "testpass"
    trace = true
    timeout = 15
    }

如果我构建并调用这个程序，我会得到以下 xmlresult:

要求:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
        <TicketObject>TicketSearch</TicketObject>
        <OwnerID>heu</OwnerID>
    </soapenv:Body>
</soapenv:Envelope>

回复:

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope
    soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Client</faultcode>
            <faultstring>
                SOAPAction shall match 'uri#method' if present (got 'Dispatch', expected '#TicketObject'
            </faultstring>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

如果我然后更改行之后的行

xmlresult <- invokeWS transport "Dispatch" () body (RawParser id)

到

xmlresult <- invokeWS transport "#TicketObject" () body (RawParser id)

故障字符串变为

<faultstring>
    Denied access to method (TicketObject) in class (main) at /opt/otrs/Kernel/cpan-lib/SOAP/Lite.pm line 2810.
</faultstring>

我在网上搜索了一些解决方案，我只找到了这个

• http://otrs.perl-services.de/… 关于票务搜索，当然还有OTRS 3.3 API
• http://blog.otrs.org -> 票务搜索 (perl)
• OTRS Client in Java
• OTRS iPhoneObject providing JSON

最后一个我成功地获得了结果 - 但仅限于 iPhoneObject 和 TicketGet - 不幸的是 TicketSearch 似乎不是 支持。

谁能告诉我请求的有效 XML 应该是什么样子的？

我还找到了How to create an otrs ticket using a soap request .Net - 使用网络 服务 - 但不幸的是我不知道如何创建这样的服务。

最佳答案

您将在 Using javax.xml.soap to access OTRS SOAP service without WSDL 中找到一个 XML 片段.
