Question

我正在尝试从PL / SQL代码调用web服务，该代码将接受itemnumber作为输入参数，并将返回大约8个输出参数，一些是字符串，而几个将是base64binay编码的PDF文件。

当我从SoapUI测试相同的WSDL时，它会返回正确的响应。

但在我的PL / SQL代码中，我得到415不支持的媒体类型错误。你能不能帮我解决这个问题，我在最近5天遇到了这个错误。提前谢谢。

下面是我的虚拟代码，一旦工作正常，我需要转换为正确的函数。

此问题现已解决，问题是根据SOAP Web服务类型设置标头不正确。

sys.UTL_HTTP.SET_HEADER(http_req, 'Content-Type', 'application/soap+xml;charset=UTF-8');
   utl_http.set_header(http_req, 'Content-Length', length(soap_request));
utl_http.set_header (http_req, 'Transfer-Encoding', 'chunked');
sys.utl_http.set_header(http_req, 'User-Agent', 'Apache-HttpClient/4.1.1 (java 1.5)');
  utl_http.set_header(http_req, 'SOAPAction', '');

关于正确标题类型的线索，即“内容类型”和“用户代理”，我在查看Raw标签时从SoapUI获得。
