我可能不是唯一一个在Stackoverflow上发布此问题的人，但不幸的是，他们都没有解决我的问题。
我开发了一个通过 SOAP API 连接到服务器的开放移动应用程序，当通过 Postman 测试 API 时，它会返回正确的结果，但是当运行应用程序时，API 返回 HTML 而不是 XML。它不会执行 php 文件并触发函数。
-(void)loginRequest{
@try {
NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
NSString *password = [NSString stringWithFormat:@"%@", [self md5:SOAP_PASSWORD]];
[params setObject:SOAP_USER_NAME forKey:@"apiKey"];
[params setObject:password forKey:@"apiPassword"];
NSError *error = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:params options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonString;
if(!jsonData){
// NSLog(@"Got an error: %@", error);
}
else
jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSString *parameters = [NSString stringWithFormat:@"<attributes xsi:type="xsd:string">%@</attributes>", jsonString];
NSString *envelope = [self createEnvelope:@"apiLogin" forNamespace:@"urn:Opencart" forParameters:parameters];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString: URL]];
[request setHTTPMethod:@"POST"];
NSMutableDictionary *defaultHeaders = [[NSMutableDictionary alloc] init];
[defaultHeaders setValue:@"gzip" forKey:@"Accept-Encoding"];
[defaultHeaders setValue:@"en, en-us;q=0.8" forKey:@"Accept-Language"];
[defaultHeaders setValue:@"text/xml; charset=utf-8" forKey:@"Content-Type"];
[defaultHeaders setValue:@"urn:Opencart_Api_Model_Server_HandlerAction" forKey:@"SOAPAction"];
[defaultHeaders setValue:@"com.lognllc.Magento-iOS-Example/1.0.0 (unknown, iPhone OS 8.1, iPhone Simulator, Scale/2.000000)" forKey:@"User-Agent"];
[request setAllHTTPHeaderFields:defaultHeaders];
[request setHTTPBody:[envelope dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if(connection){
webData = [NSMutableData data];
}
else{
NSLog(@"The Connection is null error: %@", error);
}
}
@catch (NSException *e) {
NSLog(@"catching %@ reason 1 %@", [e name], [e reason]);
}
}
我从客户端服务器得到的返回结果如下：

HTML文件很长，所以我粘贴了其中的一部分。但是在日志末尾，我收到此错误消息：
发生错误 { NSXMLParserErrorColumn = 14; NSXMLParserErrorLineNumber = 77; NSXMLParserErrorMessage = "AttValue： \" 或 ' expect";}
文件名是AppServer.php它应该执行文件并根据调用的API返回XML结果。
正确结果的示例应在演示服务器上测试：
{">横幅"：[{"标题"："图片"，"链接"："/索引.php？路由=产品/产品&product_id=47"，"图像"："http://domain.comm/image/data/banners/3.png"}，{"标题"："测试"，"链接"："图像"，"图像"："http://domain.comm/image/data/banners/4.png"}，{"标题"："某物"，"链接"："/索引.php？路由=产品/产品&路径=57&product_id=49"，"图像"："http://domain.comm/image/data/banners/6.png"}，{"标题"："asdgasdg"，"链接"："/索引.php？路由=产品/产品&路径=57&product_id=49"，"图像"："http://domain.comm/image/data/banners/5.png"}，{"标题"："图像"，"链接"："/索引.php？路由=产品/产品&路径=57&product_id=49"，"图像"："http://domain.comm/image/data/banners/1.png"}]，"模块"：{"特色"：[{"product_id"："47"，"拇指"："http://domain.com/image/cache/data/hp_1-187.5x187.5.jpg"，"名称"："HP
同样，我将文件的一部分而不是整个文件粘贴为摘要，因此问题不会太长。
我检查了服务器配置，发现服务器上安装了SOAP，XMLWriter和XMLReader，但错误仍然存在。试图解决这个问题 2 周但没有结果，这真的很令人头疼。如果有人已经经历过并且可以提供建议，我将感谢您的帮助。
经过一段时间的研究，我在客户端的服务器上发现了错误，他将他的服务器配置为强制 www 重定向，因此每当来自非 www 域的请求时，它都应该重定向到 www，我更改了 API URL 调用并添加了"www"，现在它正在加载应用程序。
