Question

我的参数是

Request1 = <Request> <name>2</name> <pwd>1</pwd> </Request>

Request2 = value1

我的代码是

-(void)webRequestCommnunication
{
//Web Service Call
 NSString *soapMessage = [NSString stringWithFormat:
                         @"<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"> <soap:Body><Method1 xmlns=\"http://tempuri.org/\"><Request1><Request> <name>2</name> <pwd>1</pwd> </Request></Request1><Request2>value1</Request2></Method1></soap:Body></soap:Envelope>"];

NSURL *url = [NSURL URLWithString:@"http://localIPaddress/servicename1/servicename2/Method1.svc"];

theRequest = [NSMutableURLRequest requestWithURL:url];


NSString *msgLength = [NSString stringWithFormat:@"%lu", (unsigned long)[soapMessage length]];

[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/service1/Method1" forHTTPHeaderField:@"Soapaction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
webData = [[NSMutableData alloc]init];
if(theConnection)
{

    NSLog(@"Connected....");
}
else
{
    NSLog(@"theConnection is NULL");
}
}

我想在Method1中传递Request1，Request2，但是它会抛出异常，因为格式化程序在尝试反序列化消息时引发了异常：反序列化操作请求消息体时出错＆＃39; Method1＆＃39;。结束元素＆＃39; Request1＆＃39;来自命名空间＆＃39; http://tempuri.org/＆＃39;预期。找到元素＆＃39;请求＆＃39;来自命名空间＆＃39; http://tempuri.org/＆＃39;。第1行，第276位......

任何人都可以建议我做错了吗？

终于有了解决方案！

在发送Request1参数时，＆lt;，＆gt;在Soap格式中不解析符号，只验证符号的父标记，修改后的代码为

-(void)webRequestCommnunication
{
//Web Service Call
 NSString *soapMessage = [NSString stringWithFormat:
                     @"<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"> <soap:Body><Method1 xmlns=\"http://tempuri.org/\"><Request1><Request1>&lt;Request&gt;&lt;name&gt;2&lt;/name&gt;&lt;pwd&gt;1&lt;/pwd&gt;&lt;/Request&gt;</Request1><Request2>value1</Request2></Method1></soap:Body></soap:Envelope>"];

NSURL *url = [NSURL URLWithString:@"http://localIPaddress/servicename1/servicename2/Method1.svc"];

theRequest = [NSMutableURLRequest requestWithURL:url];


 NSString *msgLength = [NSString stringWithFormat:@"%lu", (unsigned long)[soapMessage length]];

[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/service1/Method1" forHTTPHeaderField:@"Soapaction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
webData = [[NSMutableData alloc]init];
if(theConnection)
{

   NSLog(@"Connected....");
}
else
{
  NSLog(@"theConnection is NULL");
}
}

如何使用Objective c在WCF服务中的方法中传递2个参数？
