Changed as you said, there is a return value, but no matter what send the string is the same ({" obj ":" 003 "})

But I use the test tool to send {" token ":" 14123 ss23sf3oodhgl38403 ", "msgType" : "10001", "msgBody" : {" manifestNo ":" 20180923004 ", "plateNumber" : "jin AB0322", "driverName" : "zhang mowgli", "driverIdentityCardNo" : "132305198907050043"}} return values for ({" obj ":" 004 "})

Test tool information is as follows:
<? The XML version="1.0" encoding="utf-8"?>

{" obj ":" 004 "} & lt;/return>
<:/ns2 processResponse>

The client code

 procedure TForm1. Button3Click (Sender: TObject); 
Var 
Tmp_p: process; 
Tmp_r: Widestring; 
The begin 
//HTTPRIO1. HTTPWebNode. UseUTF8InHeader:=True; 
Tmp_p:=process. Create; 
//tmp_r:=processResponse. Create; 
Tmp_p. Arg0:=WidestringToString (Memo1. Lines. The Text). 
Tmp_r:=GetSolidWasteService (False, ' ', HTTPRIO1). The process (tmp_p); 
//Memo2. Lines. Text:=tmp_r. Return; 
Memo2. Lines. Text:=(tmp_r); 
end;

Where there is a problem?

CodePudding user response:

Back then delphi2010 did the client, the return value is {" obj ":" 003 "}, doubt is caused, the client receives is null because the valid characters or invalid characters back {" obj ":" 003 "}, return code label format error,
Use testing tools to send effective string {" obj ":" 004 "},
