导入Exchange Web服务（EWS）wsdl文件时如何解决无法解析的类型？ [英] How to fix unresolved types when importing Exchange Web Services (EWS) wsdl file?

问题描述

从 https：//ourmail.server/ews/services.wsdl ，在生成的services.pas中，最初出现了大量的 WSDL文档中未表示的以下类型在生成的services.pas中。

然后将wdsl文件下载到磁盘，看到它引用了 http://schemas.microsoft.com/exchange/services/2006/邮件和 http://schemas.microsoft.com/exchange/services/2006 / types ，已下载 https：//ourmail.server/ews/types.xsd 和 https：//ourmail.server/ews/messages.xsd
并修改了从

When importing the wsdl file from https://ourmail.server/ews/services.wsdl, I initially got a ton of "The following types, referred to in the WSDL document are not being represented in this file" in the generated services.pas.
I then downloaded the wdsl file to disk, saw that it referenced http://schemas.microsoft.com/exchange/services/2006/messages and http://schemas.microsoft.com/exchange/services/2006/types, downloaded https://ourmail.server/ews/types.xsd and https://ourmail.server/ews/messages.xsd and modified the start of services.wdsl from

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:s="http://www.w3.org/2001/XMLSchema" targetNamespace="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
    <wsdl:types>
        <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
            <xs:import namespace="http://schemas.microsoft.com/exchange/services/2006/messages" schemaLocation="messages.xsd"/>
        </xs:schema>
    </wsdl:types>

至：

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:s="http://www.w3.org/2001/XMLSchema" targetNamespace="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
    <wsdl:types>
        <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
            <xs:import namespace="http://schemas.microsoft.com/exchange/services/2006/messages" schemaLocation="file://d:/testing/web/exchange web services/types.xsd"/>
            <xs:import namespace="http://schemas.microsoft.com/exchange/services/2006/messages" schemaLocation="file://d:/testing/web/exchange web services/messages.xsd"/>
        </xs:schema>
    </wsdl:types>

现在生成的services.pas包含（仅）以下错误：

Now the generated services.pas contains (only) these errors:

// ************************************************************************ //
// The following types, referred to in the WSDL document are not being represented
// in this file. They are either aliases[@] of other types represented or were referred
// to but never[!] declared in the document. The types from the latter category
// typically map to predefined/known XML or Embarcadero types; however, they could also
// indicate incorrect WSDL documents that failed to declare or import a schema type.

// !:short           - "http://www.w3.org/2001/XMLSchema"[Gbl]

我可以添加什么 xs：import行来解决这些问题？

我到处搜索了W3C的datatypes.xsd和structure.xsd并尝试了

What "xs:import" line can I add to resolve these?
I have searched around for the W3C's datatypes.xsd and structures.xsd and tried the same approach, but I can't get it to work.

推荐答案

原来，那些类型没有被表示文件很好。
对于大多数这些类型来说，似乎后一类的类型通常映射到预定义/已知的XML或Embarcadero类型。诸如nonNegativeInteger和Base64Binary之类的奇怪变量在源代码中的其他任何地方都没有使用。

It turns out those "types not being represented" in the file are fine. It seems as if "The types from the latter category typically map to predefined/known XML or Embarcadero types" is exactly the case for most of these types. The 'strange' ones like nonNegativeInteger and Base64Binary are not used anywhere else in the source.

另一句话：我在指定初始WDSL时出错。该URL给出了证书错误，阻止了从属文件的导入。一旦尝试了没有证书错误的备用URL， https://webmail.ourmailserver.nl/ews/messages .xsd 和 https://webmail.ourmailserver.nl/ews/types.xsd 已正确导入，而我不再需要从磁盘上导入。

One additional remark: I made an error specifying the initial WDSL. That URL gave a certificate error which prevented the dependent files from being imported. Once I tried an alternate URL without cert errors the https://webmail.ourmailserver.nl/ews/messages.xsd and https://webmail.ourmailserver.nl/ews/types.xsd were imported properly and I no longer had to do that from disk.

由于以下结构，最初生成的文件无法编译：

The generated file initially does not compile because of the following constructs:

type

ProtectionRuleAllInternalType = string;      
ProtectionRuleTrueType = string;   

ProtectionRuleConditionType = class(TRemotable)
private
  FAllInternal: ProtectionRuleAllInternalType;
  FAllInternal_Specified: boolean;
  procedure SetAllInternal(Index: Integer; const AProtectionRuleAllInternalType: ProtectionRuleAllInternalType);
public
published
  property True: ProtectionRuleTrueType;
end;

procedure ProtectionRuleConditionType.SetAllInternal(Index: Integer; const AProtectionRuleAllInternalType: ProtectionRuleAllInternalType);
begin
  FAllInternal := AProtectionRuleAllInternalType;
  FAllInternal_Specified := True;
end;

在setter中，布尔值是什么意思，但编译器认为它是正确发布的名为True，并会发出不兼容的类型。
我更改了 FAllInternal_Specified：= True;到 FAllInternal_Specified：= System.True;

In the setter, what is meant is the boolean value, but the compiler thinks it is the published properly named True, and will issue an 'Incompatible types'. I changed the "FAllInternal_Specified := True;" to "FAllInternal_Specified := System.True;"

以同样的方式，有两个发布的属性Create，并且编译器认为这些是重写基本调用中的构造函数。我将其名称更改为MyCreate。

In the same manner, there are two published properties Create, and the compiler thinks these are constructors overriding those in the base calls. I changed their names to MyCreate.

这使生成的文件得以编译。

This makes the generated file compile.
