使用UTL_HTTP

Question

我正在尝试使用UTL_HTTP调用Sonar删除项目API（不要问我为什么使用oracle包，我别无选择）。

我使用curl测试了我的命令，它运行正常：

curl -u c3b4gj1k11a12n726kjo0eaaf1d0035dt6afd7cg5d: -d "key=community.developer.scott" http://sonar:9000/api/projects/delete

但是当我尝试在PL / SQL中实现它时，我有一个内部服务器错误

declare
    l_command varchar2(2500) := 'http://sonar:9000/api/projects/delete?key=community.developer.scott';
    l_req      UTL_HTTP.req;
    l_response UTL_HTTP.resp;
begin

   l_req      := UTL_HTTP.begin_request(l_command, 'POST');
   UTL_HTTP.SET_HEADER(l_req,'Authorization','Basic c3b4gj1k11a12n726kjo0eaaf1d0035dt6afd7cg5d');

   l_response := UTL_HTTP.GET_RESPONSE(l_req);
   if l_response.status_code != 200 then 
     display_msg('Error accessing to Sonar (error code: ' || l_response.status_code||')');
     display_msg('HTTP response reason phrase: ' || l_response.reason_phrase);
   end if;
   UTL_HTTP.end_response(l_response);
    exception
        when others then display_msg('Http detailed sqlerrm: '|| utl_http.GET_DETAILED_SQLERRM());
end;

下面是服务器日志：

有人知道如何设置HTTP标头以使用令牌身份验证调用Sonar API吗？
