關於iOS呼叫SOAP協議的WebServices介面
在我們做專案的時候，往往移動客戶端是現有平臺的一個擴充套件，因此客戶端實現往受限於服務採用的技術。那麼目前大多數在一個新專案開始的時候，可能會考慮如果要考慮移動客戶端的話會提供介面，但是，有些時候服務端已經有介面，而且這個介面可能不僅僅是提供給移動平臺使用的，比如它的實現採用的是SOAP協議的WebServices實現。那麼這個時候iOS端應該要如何去做呢？
//1. 建立URL
NSURL *url = [NSURL URLWithString:@"http://www.joy11.com/WebService/LiAnService.asmx"];
//2. 建立請求(post方式建立可變請求)
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
//3. 指定請求為post方式
[request setHTTPMethod:@"POST"];
//4. 準備提交的資料
NSString *soapMessage = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
"<soap12:Header>"
"<AuthSoapHd xmlns=\"http://tempuri.org/\">"
"<strUserName>lian2014</strUserName>" //填寫soap herder賬戶
"<strPassword>lian0403</strPassword>" //填寫soap herder密碼
"</AuthSoapHd>"
"</soap12:Header>"
"<soap12:Body>"
"<LoginLink xmlns=\"http://tempuri.org/\">"
"<key>%@</key>" //填寫使用者Id
"</LoginLink>"
"</soap12:Body>"
"</soap12:Envelope>", [AccountTool sharedAccountTool].currentAccount.uid];
NSURL *url1 = [NSURL URLWithString:@"http://www.joy11.com/webservice/lianservice.asmx"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url1];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/LoginLink" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
