Delphi 2007 WSDL导入，设置SOAP头信息

发布于 2024-08-02 08:16:43 字数 7044 浏览 6 评论 0原文

在 Delphi 2007 中导入 WDSL 工作正常，但会生成“无法展开”警告（下面​​的代码片段 1 [就像 StackOverFlow 上已经记录的另一个问题]）。

但是，从生成的代码中尚不清楚我们如何设置标头 (REQUESTOR:pIn, REQUEST_USER:pIn, REQUEST_PASSWORD:pIn)。在网络上的其他地方，我们还尝试了命令行实用程序 WDSLImp，它允许我们使用开关，例如，解开文字。不好。

片段 2 显示了初始化内容，我们尝试用实际值替换三个标头参数。最终结果应该出现在界面上，如代码片段 3 所示。

非常感谢所有帮助。

Importing WDSL in Delphi 2007 works fine, but generates a Cannot Unwrap warning (code snippet 1, below [like another question already logged on StackOverFlow]).

However, it is how we set the headers (REQUESTOR:pIn, REQUEST_USER:pIn, REQUEST_PASSWORD:pIn) that is unclear from the generated code. Looking elsewhere on the Net, we also tried the command line utilitiy WDSLImp, which allowed us to use switches to, for example, unwrap literals. No good.

Snippet 2 shows the initialization stuff, which we have variously tried substituting real values for the three header parameters. The end result should appear over the interface like this snippet 3.

All help very much appreciated.
