iPhone调用Web Service示例

因为有些Web Service参数要求有顺序，所以参数使用了NSArray

 

+ (NSData *) SoapCall:(NSString *)method  PostData:(NSString *)post
{
    NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
    [postData autorelease];
    
    NSString *soapAction = [NSString stringWithFormat:@"%s/%@",SoapPrefix , method  ];
    
    NSURL *url=[[NSURL alloc]initWithString:[ [ NSString alloc ] initWithUTF8String: SoapURL ] ];
    NSMutableURLRequest  *request=[[NSMutableURLRequest alloc]init];
    
    [request setTimeoutInterval: 10 ];
    [request setCachePolicy:NSURLRequestReloadIgnoringCacheData];
    [request setURL: url ] ;
    [request setHTTPMethod:@"POST"]; 
    [request setValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];  
    [request setValue:soapAction forHTTPHeaderField:@"SOAPAction"];
    
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:postData];  
    
    
    NSError *err=nil;
    NSData *data=[NSURLConnection sendSynchronousRequest:request
                                       returningResponse:nil 
                                                   error:&err];
    return data ;
}


+ (NSData *)SoapInvoke:(NSString *)method params:(NSArray *)params
{
    NSMutableString * post = [[ NSMutableString alloc ] init ] ;
    [ post autorelease ];
    
    [ post appendString:
     @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" 
     "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\""
     " xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\""
     " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">\n"
     "<soap:Body>\n" ];
    
    [ post appendString:@"<"];
    [ post appendString:method];
    [ post appendString:@">\n"];
    
    for (NSDictionary *dict in params)
    {
        NSString *value = nil;
        
        NSString *key = [[dict keyEnumerator] nextObject];
        
        if (key != nil)
        {
            value = [dict valueForKey:key];
            
            [ post appendString:@"<"];
            [ post appendString:key];
            [ post appendString:@">"];
            if( value != nil )
            {
                [ post appendString:value];
            }
            else
            {
                [ post appendString:@""];
            }
            
            [ post appendString:@"</"];
            [ post appendString:key];
            [ post appendString:@">\n"];
        }
    }
    
    [ post appendString:@"</"];
    [ post appendString:method];
    [ post appendString:@">\n"];
    
    [ post appendString:
     @"</soap:Body>\n"
     "</soap:Envelope>\n"
     ];
    
    //    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"login" ofType:@"json"];
    //    NSString *test = [NSString stringWithContentsOfFile:filePath];
    NSLog(@"====================request=========================\n%@\n", post);
    
    return [self SoapCall:method PostData:post];
}
