ios - iOS 应用程序中的 SOAP

Question

我正在尝试开发一个使用来自 SOAP 服务的数据的应用程序。这是我第一次使用 SOAP 服务。在阅读了几个教程后，我认为我能够以正确的方式设置对服务的请求，但我总是在响应中收到错误。怎么了？!

NSString *soapMessage = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
                 "<env:Envelope xmlns:env=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:ns1=\"urn:Lottery.Intf-ILottery\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:enc=\"http://www.w3.org/2003/05/soap-encoding\">\n"
                 "<env:Body>\n"
                 "<ns1:GetUpcomingLotteries env:encodingStyle=\"http://www.w3.org/2003/05/soap-encoding\">\n"
                 "<EntityID xsi:type=\"xsd:int\">2</EntityID>\n"
                 "<Password xsi:type=\"xsd:string\">Smart@Winners</Password>\n"
                 "<SortBy xsi:type=\"xsd:int\">0</SortBy>\n"
                 "<limit xsi:type=\"xsd:int\">0</limit>\n"
                 "</ns1:GetUpcomingLotteries>\n"
                 "</env:Body>\n"
                 "</env:Envelope>"];


NSURL *sRequestURL = [NSURL URLWithString:@"xxxxxxxxx"];
NSMutableURLRequest *myRequest = [NSMutableURLRequest requestWithURL:sRequestURL];
NSString *sMessageLength = [NSString stringWithFormat:@"%d", [soapMessage length]];

[myRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[myRequest addValue: @"urn:Lottery.Intf-ILottery/GetUpcomingLotteries" forHTTPHeaderField:@"SOAPAction"];
[myRequest addValue: sMessageLength forHTTPHeaderField:@"Content-Length"];

[myRequest setHTTPMethod:@"POST"];
[myRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:myRequest returningResponse:&response error:&error];
NSString *str=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];

下载 ATTACHED PROJECT HERE//在.h文件中

#import "TBXML.h"

@property(retain,nonatomic)NSString *xmlString;

@property(nonatomic,retain)NSMutableData *webResponseData;

//在.m文件中

-(void)method_GetUpcomingLotteries
{



    NSString *soapMessage = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
                             "<env:Envelope xmlns:env=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:ns1=\"urn:Lottery.Intf-ILottery\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:enc=\"http://www.w3.org/2003/05/soap-encoding\">\n"
                             "<env:Body>\n"
                             "<ns1:GetUpcomingLotteries env:encodingStyle=\"http://www.w3.org/2003/05/soap-encoding\">\n"
                             "<EntityID xsi:type=\"xsd:int\">2</EntityID>\n"
                             "<Password xsi:type=\"xsd:string\">Smart@Winners</Password>\n"
                             "<SortBy xsi:type=\"xsd:int\">0</SortBy>\n"
                             "<limit xsi:type=\"xsd:int\">0</limit>\n"
                             "</ns1:GetUpcomingLotteries>\n"
                             "</env:Body>\n"
                             "</env:Envelope>"];


    NSURL *sRequestURL = [NSURL URLWithString:@"xxxxxxxxx"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:sRequestURL];
    NSString *sMessageLength = [NSString stringWithFormat:@"%d", [soapMessage length]];

    [request addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue: @"urn:Lottery.Intf-ILottery/GetUpcomingLotteries" forHTTPHeaderField:@"SOAPAction"];
    [request addValue: sMessageLength forHTTPHeaderField:@"Content-Length"];

    [request setHTTPMethod:@"POST"];



    [request setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

    NSLog(@"soapMessage===\n %@",soapMessage);

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

    if( theConnection ) {
        NSLog(@"hiii");
        [self showUpdating];
        self.webResponseData = [NSMutableData data];
    }else {
        NSLog(@"Some error occurred in Connection");

        [self showNetworkError];
    }

}


- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"Received Bytes from server: %lu", (unsigned long)[self.webResponseData length]);

    NSString * strXml = [[NSString alloc] initWithBytes: [self.webResponseData mutableBytes] length:[self.webResponseData length] encoding:NSUTF8StringEncoding];

    NSLog(@"---- %@" ,strXml);

    TBXML *sourceXML = [[TBXML alloc] initWithXMLString:strXml error:nil];
    TBXMLElement *rootElement = sourceXML.rootXMLElement;
    TBXMLElement *entryElement = [TBXML childElementNamed:@"soap:Body" parentElement:rootElement];




}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {

               [self.webResponseData  setLength:0];
           }

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
               [self.webResponseData  appendData:data];
    }

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
               NSLog(@"Some error in your Connection. Please try again.");

               [self showNetworkError];

           }

或者打开FireFox安装 SOA 客户端扩展在那儿测试你的 API

更新在 SOA 客户端检查时我得到以下 header

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><GetUpcomingLotteries xmlns="http://tempuri.org/"><EntityID>2</EntityID><Password>Smart@Winners</Password><SortBy>0</SortBy><limit>0</limit></GetUpcomingLotteries></soap:Body></soap:Envelope>

然后响应(意味着它可能是服务器错误)
