WSDL的Objective-C SOAP客户端生成器？ [英] SOAP Client Generator for Objective-C from WSDL?
问题描述
我坚持使用SOAP集成项目。我需要从iPad应用程序调用一些SOAP Web服务。
I'm stuck on a SOAP integration project. I need to call some SOAP Web Services from an iPad app.
我有 WSDL ，我需要生成Objective-C类来调用服务调用。
I have the WSDL, and I need to generate the Objective-C classes to invoke the service calls.
Mac开发人员库有一个< a href =https://developer.apple.com/library/mac/documentation/Networking/Conceptual/UsingWebservices/Tasks/Tasks.html#//apple_ref/doc/uid/TP30000985-CH101-SW3\"rel =nofollow >示例：使用HTTP身份验证调用SOAP操作，但它链接到的示例代码已损坏（ SOAP_AuthExample.dmg，404 。
The Mac developer library has an "Example: Calling a SOAP Operation with HTTP Authentication", but the sample code it links to is broken (SOAP_AuthExample.dmg, 404).
Web服务核心编程指南甚至说（强调）补充）：
The Web Services Core Programming Guide even says (emphasis added):
目前，OS X 不提供高级支持，用于从WSDL文件中提取SOAP函数。但是，您可以使用NSXMLParser从URL将WSDL文件读入内存。然后，在文件中搜索特定方法名称或查找与服务关联的URL相对简单。通过更多的努力，您可以提取方法名称，数据类型和参数名称来构建SOAP调用。然后，您可以使用Web Services Core框架进行SOAP调用并解析响应。
"Currently, OS X provides no high-level support for extracting SOAP functions from WSDL files. You can use NSXMLParser to read a WSDL file into memory from a URL, however. It is then relatively simple to search the file for a particular method name or to find a URL associated with a service. With a bit more effort, you can extract method names, data types, and parameter names to build a SOAP call. You can then use the Web Services Core framework to make SOAP calls and parse the responses."
我还发现了以下三个然而，第一个是关于一些丢失的文件抛出错误，第二个代码生成并且当我尝试构建（并且重构器不工作）时无休止的ARC错误流，第三个是paywalled。
I've also found the following three generators; however, the first is throwing an error about some missing files, the second's code generates and endless stream of ARC errors when I try to build (and a refactor is not working), and the third is paywalled.

任何人都可以引导我朝着正确的方向前进吗？
Can anyone steer me in the right direction?
推荐答案
几个月前我遇到了同样的情况，我目前正在使用需要连接到SOAP服务的iPad应用程序。我已经有了类，但它们是特定的我的项目的ic，我无权分享。但是，我正在制作一个更通用的Objective-C类（无论如何是所有SOAP服务器的最终解决方案），以便与Github上的世界共享它。
I was in your same situation a couple of months ago, and I'm currently working in an iPad app that requires to connect to a SOAP service. I already have the classes, but they are specific for my project and I'm not authorised to share it. However, I'm making a more generic Objective-C class (in any case the final solution for all the SOAP servers) to share it with the world on Github.
首先，您必须设置SOAP消息。它有一个像这样的通用结构：
First of all you have to set the SOAP message. It has a common structure like this:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
// here comes the header information: credentials, connection information. If needed, of course
</soap:Header>
<soap:Body>
// here comes the request parameters. In my case, these parameters are related to a resource called SOAPAction (That identifies the method to be called. e.g getListOfClients). I don't know if it is the same in all servers
</soap:Body>
</soap:Envelope>
我告诉你，我正在制作应用程序的公司为我提供了方法和认证信息。我不知道这是不是你的情况，但你在这里一瞥一下该怎么做。
I say to you, the company for which I'm making the app, has provided me with the methods and authentication information. I don't know if this is your case, but you have here a general glance of what to do.
我用 AFNetworking 以这种方式发送请求：
I use AFNetworking to send the request, in this way:
NSString *messageLength = [NSString stringWithFormat:@"%lu", (unsigned long)[msg length]];
NSURL *requestURL = [NSURL URLWithString:self.requestURL];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:requestURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:30];
[theRequest addValue:[requestURL host] forHTTPHeaderField:@"Host"];
[theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:soapAction forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue:messageLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody:[msg dataUsingEncoding:NSUTF8StringEncoding]];
// sending the request
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:theRequest];
operation.responseSerializer = [AFHTTPResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *xml = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"Take the data master Yoda: %@", xml);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Bad SOAP server!. Error: %@", error.description)
}];
[[NSOperationQueue mainQueue] addOperation:operation];
self.requestURL 是服务器URL，明显。如果请求成功，那么您已准备好解析服务器的xml响应。如果没有，否则请求错误说明。
self.requestURL is the server URL, obviously. If the request was successful, then you have the server's xml response ready to parse. If not, a request error description otherwise.
