ios 手机号码查询

首先用到一个手机归属地查询的服务网站。 http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx

SOAP是简单对象访问协议，它可看成是HTTP与XML的结合，其中XML部分是作为HTTP报文的实体主体部分

[webData setLength: 0]; //注意这里需要改正一下：webData=[NSMutableData alloc ]init];

1、运行Xcode 4.4.1，新建一个Single View Application，名称为SOAP Test：

2、界面设计：打开ViewController.xib，设计界面如下所示：

在文本输入框的Attribute Inspector中设置其Keyboard属性为Number Pad。

3、之后向ViewController.h中，为文本输入框创建OutLet映射，名称为：phoneNumber；为“查询”按钮创建Action映射，事件类型为Touch Up Inside，名称为：doQuery。建立映射的方法就是打开Assistant Editor，选中某一控件，按住Ctrl，拖向ViewController.h，可以参考前面的文章。

4、在ViewController.h中添加代码：

4.1 在@interface那行最后添加代码

<NSXMLParserDelegate, NSURLConnectionDelegate>

使ViewController遵守这两个协议。前者用来解析XML，后者用于网络连接。

4.2 在@end之前添加代码

@property (strong, nonatomic) NSMutableData *webData; @property (strong, nonatomic) NSMutableString *soapResults; @property (strong, nonatomic) NSXMLParser *xmlParser; @property (nonatomic) BOOL elementFound; @property (strong, nonatomic) NSString *matchingElement; @property (strong, nonatomic) NSURLConnection *conn;

5、在ViewController.m中添加代码：

5.1 在@implementation之后添加代码

@synthesize webData; @synthesize soapResults; @synthesize xmlParser; @synthesize elementFound; @synthesize matchingElement; @synthesize conn;

5.2 实现doQuery方法

- (IBAction)doQuery:(id)sender { NSString *number = phoneNumber.text; // 设置我们之后解析XML时用的关键字，与响应报文中Body标签之间的getMobileCodeInfoResult标签对应 matchingElement = @"getMobileCodeInfoResult"; // 创建SOAP消息，内容格式就是网站上提示的请求报文的实体主体部分 NSString *soapMsg = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>" "<soap12:Envelope " "xmlns:xsi=\" http://www.w3.org/2001/XMLSchema-instance \" " "xmlns:xsd=\" http://www.w3.org/2001/XMLSchema \" " "xmlns:soap12=\" http://www.w3.org/2003/05/soap-envelope \">" "<soap12:Body>" "<getMobileCodeInfo xmlns=\" http://WebXml.com.cn/ \">" "<mobileCode>%@</mobileCode>" "<userID>%@</userID>" "</getMobileCodeInfo>" "</soap12:Body>" "</soap12:Envelope>", number, @""]; // 将这个XML字符串打印出来 NSLog(@"%@", soapMsg); // 创建URL，内容是前面的请求报文报文中第二行主机地址加上第一行URL字段 NSURL *url = [NSURL URLWithString: @" http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx "]; // 根据上面的URL创建一个请求 NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]]; // 添加请求的详细信息，与请求报文前半部分的各字段对应 [req addValue:@"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [req addValue:msgLength forHTTPHeaderField:@"Content-Length"]; // 设置请求行方法为POST，与请求报文第一行对应 [req setHTTPMethod:@"POST"]; // 将SOAP消息加到请求中 [req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]]; // 创建连接 conn = [[NSURLConnection alloc] initWithRequest:req delegate:self]; if (conn) { webData = [NSMutableData data]; }}

5.3 在@end之前添加代码

#pragma mark -#pragma mark URL Connection Data Delegate Methods // 刚开始接受响应时调用-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *) response{ [webData setLength: 0]; //注意这里需要改正一下：webData=[NSMutableData alloc ]init];} // 每接收到一部分数据就追加到webData中-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *) data { [webData appendData:data];} // 出现错误时-(void) connection:(NSURLConnection *)connection didFailWithError:(NSError *) error { conn = nil; webData = nil;} // 完成接收数据时调用-(void) connectionDidFinishLoading:(NSURLConnection *) connection { NSString *theXML = [[NSString alloc] initWithBytes:[webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding]; // 打印出得到的XML NSLog(@"%@", theXML); // 使用NSXMLParser解析出我们想要的结果 xmlParser = [[NSXMLParser alloc] initWithData: webData]; [xmlParser setDelegate: self]; [xmlParser setShouldResolveExternalEntities: YES]; [xmlParser parse];}

5.4 在@end之前添加代码#pragma mark -#pragma mark XML Parser Delegate Methods // 开始解析一个元素名-(void) parser:(NSXMLParser *) parser didStartElement:(NSString *) elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *) qName attributes:(NSDictionary *) attributeDict { if ([elementName isEqualToString:matchingElement]) { if (!soapResults) { soapResults = [[NSMutableString alloc] init]; } elementFound = YES; }} // 追加找到的元素值，一个元素值可能要分几次追加-(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string { if (elementFound) { [soapResults appendString: string]; }} // 结束解析这个元素名-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:matchingElement]) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"手机号码信息" message:[NSString stringWithFormat:@"%@", soapResults] delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alert show]; elementFound = FALSE; // 强制放弃解析 [xmlParser abortParsing]; }} // 解析整个文件结束后- (void)parserDidEndDocument:(NSXMLParser *)parser { if (soapResults) { soapResults = nil; }} // 出错时，例如强制结束解析- (void) parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError { if (soapResults) { soapResults = nil; }}

#parm mark=======下面都是重复的了。=============

// 开始查询- (IBAction)doQuery:(id)sender { NSString *number = phoneNumber.text; // 设置我们之后解析XML时用的关键字，与响应报文中Body标签之间的getMobileCodeInfoResult标签对应 matchingElement = @"getMobileCodeInfoResult"; // 创建SOAP消息，内容格式就是网站上提示的请求报文的实体主体部分 NSString *soapMsg = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>" "<soap12:Envelope " "xmlns:xsi=\" http://www.w3.org/2001/XMLSchema-instance \" " "xmlns:xsd=\" http://www.w3.org/2001/XMLSchema \" " "xmlns:soap12=\" http://www.w3.org/2003/05/soap-envelope \">" "<soap12:Body>" "<getMobileCodeInfo xmlns=\" http://WebXml.com.cn/ \">" "<mobileCode>%@</mobileCode>" "<userID>%@</userID>" "</getMobileCodeInfo>" "</soap12:Body>" "</soap12:Envelope>", number, @""]; // 将这个XML字符串打印出来 NSLog(@"%@", soapMsg); // 创建URL，内容是前面的请求报文报文中第二行主机地址加上第一行URL字段 NSURL *url = [NSURL URLWithString: @" http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx "]; // 根据上面的URL创建一个请求 NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]]; // 添加请求的详细信息，与请求报文前半部分的各字段对应 [req addValue:@"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [req addValue:msgLength forHTTPHeaderField:@"Content-Length"]; // 设置请求行方法为POST，与请求报文第一行对应 [req setHTTPMethod:@"POST"]; // 将SOAP消息加到请求中 [req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]]; // 创建连接 conn = [[NSURLConnection alloc] initWithRequest:req delegate:self]; if (conn) { webData = [NSMutableData data]; }}5.3 在@end之前添加代码#pragma mark -#pragma mark URL Connection Data Delegate Methods // 刚开始接受响应时调用-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *) response{ [webData setLength: 0];} // 每接收到一部分数据就追加到webData中-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *) data { [webData appendData:data];} // 出现错误时-(void) connection:(NSURLConnection *)connection didFailWithError:(NSError *) error { conn = nil; webData = nil;} // 完成接收数据时调用-(void) connectionDidFinishLoading:(NSURLConnection *) connection { NSString *theXML = [[NSString alloc] initWithBytes:[webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding]; // 打印出得到的XML NSLog(@"%@", theXML); // 使用NSXMLParser解析出我们想要的结果 xmlParser = [[NSXMLParser alloc] initWithData: webData]; [xmlParser setDelegate: self]; [xmlParser setShouldResolveExternalEntities: YES]; [xmlParser parse];}

5.4 在@end之前添加代码#pragma mark -#pragma mark XML Parser Delegate Methods // 开始解析一个元素名-(void) parser:(NSXMLParser *) parser didStartElement:(NSString *) elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *) qName attributes:(NSDictionary *) attributeDict { if ([elementName isEqualToString:matchingElement]) { if (!soapResults) { soapResults = [[NSMutableString alloc] init]; } elementFound = YES; }} // 追加找到的元素值，一个元素值可能要分几次追加-(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string { if (elementFound) { [soapResults appendString: string]; }} // 结束解析这个元素名-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:matchingElement]) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"手机号码信息" message:[NSString stringWithFormat:@"%@", soapResults] delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alert show]; elementFound = FALSE; // 强制放弃解析 [xmlParser abortParsing]; }} // 解析整个文件结束后- (void)parserDidEndDocument:(NSXMLParser *)parser { if (soapResults) { soapResults = nil; }} // 出错时，例如强制结束解析- (void) parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError { if (soapResults) { soapResults = nil; }}

6、运行

其中，输入号码时单击查询，打印出的响应XML如下：

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap=" http://www.w3.org/2003/05/soap-envelope " xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance " xmlns:xsd=" http://www.w3.org/2001/XMLSchema "> <soap:Body> <getMobileCodeInfoResponse xmlns=" http://WebXml.com.cn/ "> <getMobileCodeInfoResult>151898XXXXX：江苏 南京 江苏移动全球通卡 </getMobileCodeInfoResult> </getMobileCodeInfoResponse> </soap:Body></soap:Envelope>

上面的XML进行了缩进处理，实际上打印出来的是一行。
