问题描述

问 题

报错：Entity: line 1: parser error : Start tag expected, '<' not found
以下为请求XML，用的是ASIHTTPRequest请求框架，不知错在何处
<?xml version='1.0' encoding='UTF-8' standalone='yes'?><Root><method action="E"><classPath>com.portal.android.ExecuteAndroid</classPath><methodName>changeState</methodName></method><kvdata ID="" SHIP_NAME="ceshi01" CARGO_REMARK="种用硬粒小麦100111009012吨" DOCK="E201205160096297" BERTH="E201205160096300" CARGO_TYPE="0" CARGO_NAME="种用硬粒小麦" CARGO_HS_CODE="1001110090" CARGO_WEIGHT="12" BILL_INFO="" MANIFEST_INFO="" CLIENT="" ISDECL="NODECL" CREATE_ORG="江阴市外轮代理有限公司" CREATE_ORG_ID="201307220000013086" CREATE_USER_ID="201306030000007077" CREATE_USER="杨柳絮" UPDATE_USER_ID="201306030000007077" UPDATE_USER="杨柳絮" AGENTID="E201511120021555"></kvdata></Root>

请求数据代码：
NSString *kvr = [NSString stringWithFormat:@"<kvdata ID=&quot;%@&quot; SHIP_NAME=&quot;%@&quot; CARGO_REMARK=&quot;%@&quot; DOCK=&quot;%@&quot; BERTH=&quot;%@&quot; CARGO_TYPE=&quot;%@&quot; CARGO_NAME=&quot;%@&quot; CARGO_HS_CODE=&quot;%@&quot; CARGO_WEIGHT=&quot;%@&quot; BILL_INFO=&quot;%@&quot; MANIFEST_INFO=&quot;%@&quot; CLIENT=&quot;%@&quot; ISDECL=&quot;%@&quot; CREATE_ORG=&quot;%@&quot; CREATE_ORG_ID=&quot;%@&quot; CREATE_USER_ID=&quot;%@&quot; CREATE_USER=&quot;%@&quot; UPDATE_USER_ID=&quot;%@&quot; UPDATE_USER=&quot;%@&quot; AGENTID=&quot;%@&quot;>",@"",cell.shipNameTextField.text,cargoRemark,self.dockModel.t2,self.berthModel.t2,cargoType,self.cargoModel.t2,self.cargoModel.t1,cell.cargoWeightTextField.text,cell.billInfoTextField.text,@"",cell.delegateTextField.text,@"NODECL",appDelegate.userInfo.ORG_NAME,appDelegate.userInfo.ORG_ID,appDelegate.userInfo.USER_ID,appDelegate.userInfo.USER_NAME,appDelegate.userInfo.USER_ID,appDelegate.userInfo.USER_NAME,self.personModel.t2];

         NSString *msg = [[response attributeForName:@"msg"] stringValue];
         //01是成功，其余是错误
         if (![code isEqualToString:@"01"]) {
             [self showAlert:msg];
         } else {
             NSArray *datasetArray = [rootElement elementsForName:@"kvdata"];
             NSArray *kvadaArray = [rootElement elementsForName:@"dataset"];
             GDataXMLElement *data = [kvadaArray objectAtIndex:0];
             NSArray *dataArray = [data elementsForName:@"data"];
             if ([datasetArray count] > 0) {
                 [_delegate didReceiveData:datasetArray andTag:tag];
             }else{
                 [_delegate didReceiveData:dataArray andTag:tag];
             }
         }
     }
     request = nil;

  }];

  //异常出现
  [request setFailedBlock:^{

     //NSLog(@"Failed");
     [self showAlert:@"网络请求失败，请稍后再试"];
     //        [_delegate didFairToReceiveData:nil andTag:tag];

  }];

  [request startAsynchronous];
  }

解决方案

由于把请求数据加密了，请求回调时处理数据未解密，所以导致了错误
