我正在调用以下网络服务:
-(void)verifyEmailAndPasswordWebservices
{
NSString *MD5Password = [ self MD5];
NSLog(@"text field password %@",txt_Password.text);
NSLog(@"converted password %@",MD5Password);
NSString *soapMsg =[NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
"<SOAP-ENV:Envelope SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\"xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" xmlns:tns=\"http://php:8393/includes/webservice\">"
"<SOAP-ENV:Body>"
"<ns1:LoginUserRequest xmlns:ns1=\"http://schemas.xmlsoap.org/soap/envelope/\">"
"<email xsi:type=\"xsd:string\">%@</email>"
"<pass xsi:type=\"xsd:string\">%@</pass>"
"</ns1:LoginUserRequest>"
"</SOAP-ENV:Body>"
"</SOAP-ENV:Envelope>",txt_EmailOrMobile.text,MD5Password];
//---print it to the Debugger Console for verification---
NSLog(@"soapMsg..........%@",soapMsg);
NSURL *url = [NSURL URLWithString:@"http://10.0.0.115:8393/includes/webservice/login1.php"];
req = [NSMutableURLRequest requestWithURL:url];
//---set the headers---
NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMsg length]];
[req addValue:@"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://10.0.0.115/includes/webservice/login1.php/LoginUser" forHTTPHeaderField:@"SoapAction"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];
//---set the HTTP method and body---
[req setHTTPMethod:@"POST"];
[req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];
// [activityIndicator startAnimating];
conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn)
{
webData = [[NSMutableData data] retain];
}
}
当我收到回复时,它会给我以下错误:
DONE。收到的字节数:422 显示XML(null) 分析器错误错误域= NSXMLParserErrorDomain代码= 4“无法完成操作。(NSXMLParserErrorDomain错误4。)”
我在互联网上搜索了很多。但是找不到任何东西。对此有任何帮助。

NSXMLParserErrorDomain error 4
表示XML解析器被赋予了一个空文档。这告诉我输入是null,或者你已经设法在它被提供给解析器之前改变它。
我更好地了解了您的代码。问题不是你没有得到回应。只是你不是在等它。您发送的请求是异步的,但您正试图立即填充webData
变量(即同步)。

另一种可能的共鸣可能是没有根标签。 示例:像这样的xml数据---&gt;

在您的编码方法上试用此代码
NSString *theXML = [[NSString alloc] initWithBytes: [_responseData mutableBytes] length:[_responseData length] encoding:NSUTF8StringEncoding];
