hi,all:
when I use WSMethodInvocationInvoke to call a service, a
Exc_bac_access occurs, anyone can help me.
here is the code:
NSURL *url = [NSURL URLWithString:[command endpointURI]];
NSString *method = [command method];
NSString *namespace = [command namespace];
// setup HTTP request headers
NSMutableDictionary *dict = [NSMutableDictionary
dictionaryWithDictionary:[command requestHeaders]];
[dict setObject:[command SOAPAction] forKey:@"SOAPAction"];
NSMutableDictionary *reqHeaders = [NSMutableDictionary
dictionaryWithDictionary:dict];
[reqHeaders removeObjectForKey:@" "];
NSString *headerXMLString = [command headerXMLString];
NSArray *soapHeaders;
if ([headerXMLString length]) {
soapHeaders = [NSArray arrayWithObject:headerXMLString];
} else {
soapHeaders = nil;
}
// get binding style
CFStringRef bindingStyle = kWSSOAPStyleRPC;
if ([[[command bindingStyle] lowercaseString]
isEqualToString:@"document"]) {
bindingStyle = kWSSOAPStyleDoc;
}
// setup soap request params
NSArray *paramOrder = [command paramOrder];
NSArray *paramTypes = [command paramTypes];
NSDictionary *params = [command params];
CFDictionaryRef cfParams = nil;
if (params) {
cfParams = checkDictionaryForIntegers(params);
}
WSMethodInvocationRef soapCall = [self methodInvocationWith:url
method:method
namespace:namespace
HTTPHeaders:reqHeaders
SOAPHeaders:soapHeaders
bindingStyle:bindingStyle
paramOrder:paramOrder
paramTypes:paramTypes
params:cfParams];
// invoke soap call
NSMutableDictionary *result;
//@try{
result = [NSMutableDictionary dictionaryWithDictionary:
(NSDictionary*)WSMethodInvocationInvoke(soapCall)];
here is the call stack:
