gSoap 如何使用凭据从 Web 服务读取一组数据

Question

我是 gSoap 的新手，需要创建一个 Web 服务客户端来接收包含 C 中多条记录的响应。

通过 wsdl2h 和 soapcpp2 我生成了各种中间文件，在 soapStub.h 下面

#ifndef soapStub_H
#define soapStub_H
#define SOAP_NAMESPACE_OF_ns1   "urn:eda-sw-schemas/page/salesorder"
#include "stdsoap2.h"
#ifdef __cplusplus
extern "C" {

}

上面的程序是我正在尝试做的事情的草稿： 如何通过凭据连接到 Web 服务并从 soap_call___ns1__ReadMultiple 服务获取数据集？

更新我听从了 rveerd 的建议：

我有消息：

Error 401 fault: SOAP-ENV:Server [no subcode] 
"HTTP Error" Detail: HTTP/1.1 401 Unauthorized

如果我使用浏览器连接到 url localhost:8012/ERP/WS/Vendor/Page/SalesOrder，则会向我显示用于输入凭据的面板，我输入它们并显示 wsdl 布局。

如果我使用以下 powershell 脚本，则连接有效：

$username = "myUser"
$password = "MyPasswd"

$URI = "http://localhost:8012/ERP/WS/Vendor/Page/SalesOrder"
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,(ConvertTo-SecureString -String $password -AsPlainText -Force))
$WSProxy = New-WebServiceProxy -Uri $URI -Credential $cred
$WSProxy.ReadMultiple($null, "", 0)

有用 ！

我错了什么？

Answer 1

gSoap 网站有一个basic client in C。为你的例子改变它给出：

int main()
{
  struct soap *soap = soap_new(); // allocate and initialize a context
  soap->userid = "administrator";
  soap->passwd = "password";
  struct _ns1__ReadMultiple_USCOREResult res;
  if (soap_call___ns1__ReadMultiple(soap, "http://localhost:8012/ERP/WS/Vendor/Page/SalesOrder", "", NULL, &res) == SOAP_OK) 
  {
    // process result through `res`
  }
  else
  {
    soap_print_fault(soap, stderr);
  }
  soap_destroy(soap); // delete managed deserialized C++ instances
  soap_end(soap);     // delete other managed data
  soap_free(soap);    // free the soap struct context data
}

设置 userid 和 passwd 仅在 Web 服务使用 HTTP 基本身份验证时有效。

当 SOAP 请求失败时打印错误有望让您了解哪里出了问题。

也可以通过定义宏DEBUG来build gSOAP in debug mode。
