问题描述

我有以下用于发布plsql json请求的基本代码。被执行的web服务没有任何响应，因为它只是用于执行某项任务。
但每次执行块时，我都会从Apache Tomcat获取状态码400。
我哪里错了？

I have the following basic code which i use to post a plsql json request. The webservice getting executed doesnt have any response as it is simply for carrying out a certain task.But each time i execute the block, i get the status code 400 from Apache Tomcat.Where is it that i am going wrong?

declare
  http_resp utl_http.resp;
  http_req utl_http.req;
  json_msg VARCHAR2(500);
begin

  http_req := utl_http.begin_request('http://192.168.1.194:8080/NotificationApp/sendNotification.rest', 'POST');
  utl_http.set_body_charset(http_req, 'UTF-8');
  utl_http.set_header(http_req, 'Content-Type', 'application/json');

    json_msg := '{"code":100,"id": "APA91bFSmD_gBsUwP_hraRZL20mt8p4ejGn5fC7tlciINT50Ad8oIod2T-64GVk_8rrjoqXGEpYuRcoQogG0L7aOKIjeeisTcmHiUUONbnZzn4_u0ED7QD_iNeVkh2RU8Pa-HBHwgJUgOT-TyvlM9hB4Yn9fvWER","data": "alert alert"}';

  utl_http.write_text(http_req, dbms_lob.substr(json_msg,dbms_lob.getLength(json_msg),1));

 http_resp := utl_http.get_response(http_req);

  if (http_resp.status_code >= 400) and
            (http_resp.status_code <= 499)
        then
        dbms_output.put_line(http_resp.status_code);

        end if;

  utl_http.end_response(http_resp);

end;

After a lot of searching, i got the following code from a blog. Works fine for me.

declare
req utl_http.req;
res utl_http.resp;
url varchar2(4000) := 'http://192.168.1.194:8080/NotificationApp/sendNotification.rest';
name varchar2(4000);
buffer varchar2(4000);
content varchar2(4000) := '{"code":100,"id": "APA91bFSmD_gBsUwO_hraRZL20mt8p4ejGn5fC7tlciINT50Ad8oIod2T-64GVk_8rProqXGEpYuDcoQogG0L7a0TuyeeisTcmHiUUONbnZzn4_u0ED7QD_iNeVkh1ZgU8Pa-HRtfgJUgOT-TyvlM9hB4Yn9fvOPud","data": "alert alert"}';

begin

req := utl_http.begin_request(url, 'POST',' HTTP/1.1');
utl_http.set_header(req, 'user-agent', 'mozilla/4.0');
utl_http.set_header(req, 'content-type', 'application/json');
utl_http.set_header(req, 'Content-Length', length(content));

utl_http.write_text(req, content);

res := utl_http.get_response(req);

    begin
    loop
    utl_http.read_line(res, buffer);
    dbms_output.put_line(buffer);

    end loop;
    utl_http.end_response(res);
    exception
    when utl_http.end_of_body then
    utl_http.end_response(res);
    end;
end;
