将参数发送到Web服务 [英] Send parameters to a web service

问题描述

开始之前:我正在使用目标C为Iphone编程.

Before I start: I'm programming for Iphone, using objective C.

我已经使用NSURLRequest和NSURLConnection实现了对Web服务功能的调用.然后，该函数将返回包含所需信息的XML.

I have already implemented a call to a web service function using NSURLRequest and NSURLConnection. The function then returns a XML with the info I need.

代码如下:

NSURL *url = [NSURL URLWithString:@"http://myWebService/function"];
NSMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url];
NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

我还实现了方法

• didRecieveResponse
• didRecieveAuthenticationChallenge
• didRecievedData
• didFailWithError
• connectionDidFinishLoading.

而且效果很好.

现在，我需要向该函数发送2个参数:位置"和模块".
我尝试使用以下修改:

Now I need to send 2 parameters to the function: "location" and "module".
I tried using the following modification:

NSMutableURLRequest theRequest   = [[NSMutableURLRequest alloc] initWithURL:url];
[theRequest setValue:@"USA" forHTTPHeaderField:@"location"];
[theRequest setValue:@"DEVELOPMENT" forHTTPHeaderField:@"module"];
NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

但是它似乎不起作用. 我做错了吗?有没有办法知道我是否为参数使用了错误的名称(例如，可能是"Location"或"LOCATION"，还是没关系?)? 或一种方法来知道函数正在等待哪些参数...

But it doesn't seem to work. I'm doing something wrong? is there a way to know if I'm using the wrong names for the parameters (as maybe it is "Location" or "LOCATION" or it doesn't matter?)? or a way to know which parameters is the function waiting for...

其他信息:
我无权访问Web服务的源，因此无法对其进行修改. 但是我可以访问WSDL.使函数说出来的人就在那里...但是我对此毫无意义>.< ...

Extra info:
I don't have access to the source of the web service so I can't modify it. But I can access the WSDL. The person who made the function say is all there... but I can't make any sense of it >.<...

任何帮助将不胜感激. :)

关于GET Post SOAP的一些示例

some examples about GET Post SOAP

获取请求

GET /index.html?userid=joe&password=guessme HTTP/1.1
Host: www.mysite.com
User-Agent: Mozilla/4.0

发布请求

POST /login.jsp HTTP/1.1
Host: www.mysite.com
User-Agent: Mozilla/4.0
Content-Length: 27
Content-Type: application/x-www-form-urlencoded

userid=joe&password=guessme

肥皂请求

POST /InStock HTTP/1.1
Host: www.example.org
Content-Type: application/soap+xml; charset=utf-8
Content-Length: nnn

<?xml version="1.0"?>
<soap:Envelope
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

<soap:Body xmlns:m="http://www.example.org/stock">
  <m:GetStockPrice>
    <m:StockName>IBM</m:StockName>
  </m:GetStockPrice>
</soap:Body>

</soap:Envelope>

HOST，User-Agent，Content-Length，Content-Type是请求标头中的项目

the HOST,User-Agent,Content-Length,Content-Type are items in the Request Header
