用Matlab发送SOAP请求 [英] sending SOAP request with Matlab

问题描述

我在发送Matlab SOAP请求时遇到了麻烦 callSoapService(endpoint，soapAction，message)< --http://www.mathworks.com/help/techdoc/ref/callsoapservice.html

I've been having trouble sending Matlab SOAP request callSoapService(endpoint,soapAction,message) <--http://www.mathworks.com/help/techdoc/ref/callsoapservice.html

例如，我如何在 http://www中找到端点，soapAction和消息. webservicex.net/FedWire.asmx?WSDL

我知道wsdl中有多个可能的soapActions，端点和消息，但我只是在寻找任何SOAP请求的示例.

I understand that there are multiple possible soapActions, endpoints, and messages in a wsdl but I was just looking for an example of any SOAP request.

推荐答案

这是您需要经历的过程.

This is the process you need to go through.

首先，根据WDSL定义创建一个类:

First, create a class from the WDSL definition:

url = 'http://www.webservicex.net/FedWire.asmx?WSDL';
className = createClassFromWsdl(url);

这将在当前目录中创建一个名为@FedWire的目录.您可以在此目录下创建目录，或使用以下内容探索FedWire提供的服务:

This will create a directory called @FedWire in the current directory. You can dir this directory or use the following to explore the services that FedWire offers:

methods(FedWire)

在使用Web服务之前，请创建FedWire对象的实例:

Before you can use the web service, create an instance of the FedWire object:

fw = FedWire;
classType = class(fw) % to confirm the class type.

要使用服务，例如GetParticipantByLocation，它需要输入City和StateCode:

To use a service, for example, GetParticipantByLocation, which requires a City and StateCode:

 [Result, FedWireLists] = GetParticipantsByLocation(fw, 'New York', 'NY')

结果应为true，并且FedWireLists是一个深度嵌套的结构，其中包含返回的数据.

Result should be true and FedWireLists is a deeply nested structure containing the data returned.

打开@FedWire \ GetParticipantsByLocation.m揭示了MATLAB生成的代码如何使用createSoapMessage和callSoapService.如果该服务不支持WSDL查询，则必须使用这些低级功能.

Opening @FedWire\GetParticipantsByLocation.m reveals how the MATLAB generated code is using createSoapMessage and callSoapService. If the service does not support WSDL queries, then using these low level functions becomes necessary.

createSoapMessage的参数是这样填充的:

The parameters for createSoapMessage are populated like this:

• NAMESPACE:"http://www.webservicex.net/"
• 方法:"GetParticipantsByLocation"
• 值:{'New York'，'NY'}
• 名称:{'City'，'StateCode'}
• 类型:{'{http://www.w3.org/2001/XMLSchema}字符串'，'{http://www.w3.org/2001/XMLSchema}字符串'}
• 样式:文档"

和callSoapService:

and callSoapService:

• ENDPOINT:"http://www.webservicex.net/FedWire.asmx"
• SOAPACTION:"http://www.webservicex.net/GetParticipantsByLocation"
• 消息:createSoapMessage调用的结果.

以下代码对低级调用进行相同的查询:

The following code makes the same query with the low level calls:

% createSoapMessage(NAMESPACE,METHOD,VALUES,NAMES,TYPES,STYLE) creates a SOAP message.
soapMessage = createSoapMessage( ...
  'http://www.webservicex.net/', ...
  'GetParticipantsByLocation', ...
  {'New York', 'NY'}, ...
  {'City', 'StateCode'}, ...
  {'{http://www.w3.org/2001/XMLSchema}string', ...
   '{http://www.w3.org/2001/XMLSchema}string'}, ...
  'document')

% callSoapService(ENDPOINT,SOAPACTION,MESSAGE) sends the MESSAGE,
response = callSoapService( ...
    'http://www.webservicex.net/FedWire.asmx', ...
    'http://www.webservicex.net/GetParticipantsByLocation', ...
    soapMessage);

%parseSoapResponse Convert the response from a SOAP server into MATLAB types.
[result, participants] = parseSoapResponse(response)  

使这些示例正常工作很麻烦，因为我要大写这样的服务域名，例如www.webserviceX.NET，这是从示例XML中获取的.当我更改为小写字母时，它起作用了.

I had a lot of trouble making these examples work because I was capitalizing the service domain name like this www.webserviceX.NET which I took from their example XML. When I changed to lowercase, it worked.

使用createClassFromWsdl的示例是对 http://www.mathworks.co.uk/products/bioinfo/examples.html?file=/products/demos/shipping/bioinfo/connectkeggdemo.html
