【问题描述】:

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式移动应用程序,当通过 Postman 测试 API 时,它返回正确的结果,但是在运行应用程序时,API 返回 HTML 而不是 XML。它没有执行 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,所以我粘贴了一部分。但是在日志的末尾,我收到以下错误消息:

发生错误{ NSXMLParserErrorColumn = 14; NSXMLParserErrorLineNumber = 77; NSXMLParserErrorMessage = "AttValue: \" 或 ' 预期\n"; }

文件名为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进行测试:

{"banners":[{"title":"Images","link":"/index.php?route=product/product&product_id=47","image":"http://domain. comm/image/data/banners/3.png"},{"title":"Testing","link":"Image","image":"http://domain.comm/image/data/banners/ 4.png"},{"title":"Something","link":"/index.php?route=product/product&path=57&product_id=49","image":"http://domain .comm/image/data/banners/6.png"},{"title":"asdgasdg","link":"/index.php?route=product/product&path=57&product_id=49"," image":"http://domain.comm/image/data/banners/5.png"},{"title":"Image","link":"/index.php?route=product/product&path =57&product_id=49","image":"http://domain.comm/image/data/banners/1.png"}],"modules":{"featured":[{"product_id":" 47","thumb":"http://domain.com/image/cache/data/hp_1-187.5x187.5.jpg","name":"HP

我再次粘贴部分文件而不是整个文件作为摘要,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 周没有结果真的很头疼。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。

【问题讨论】:

  • 首先,标题呢?您是否正确设置了所有需要的标头,例如身份验证、内容类型、接受等
  • 其次,有时php会在500错误或403(未经授权)的情况下发送html。将您的 html 页面保存到 pastebin 并在此处提供链接
  • 感谢您的支持我发布了我的答案,但现在我有一个新错误,某些 API 函数调用在我的服务器上测试时再次返回“文档末尾的 nsxmlparser 额外内容”它工作正常但客户端服务器不是。我已经尝试了所有可能的解决方案,但都没有成功,请问有什么建议吗?

【解决方案1】:

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进行 www 重定向,因此每当请求来自非 www 域时,它应该重定向到 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。
