VS 2008 wsdl工具將xsd：positiveInteger轉換爲字符串

Question

我有一個使用gSoap以C++編寫的Web服務。其中一個Web服務的方法是

int HS__TBusinessComponentGetContents(xsd__positiveInteger pSession, 
xsd__positiveInteger pComponentType, 
xsd__string pPath, 
xsd__string pFilter, 
xsd__string pChangedAfter, 
xsd__positiveInteger pFlags, 
xsd__string &rResult); 

使用這些類型定義： ：

typedef double     xsd__double; 
typedef wchar_t     *xsd__string; 
typedef bool      xsd__boolean; 
typedef int      xsd__int; 
typedef unsigned long long  xsd__positiveInteger; 
typedef wchar_t     *xsd__datetime; 

我用這個定義，有這個（正確）的部分生成WSDL文件

但是，當我使用Vis生成Proxy類時UAL Studio 2008中Wsdl.exe用工具來創建一個類，我可以在C＃中使用，上述方法的定義如下：

[System.Web.Services.Protocols.SoapRpcMethodAttribute("", RequestNamespace="urn:tango04-hydra-server", ResponseNamespace="urn:tango04-hydra-server")] 
    [return: System.Xml.Serialization.SoapElementAttribute("rResult")] 
    public string TBusinessComponentGetContents([System.Xml.Serialization.SoapElementAttribute(DataType="positiveInteger")] string pSession, [System.Xml.Serialization.SoapElementAttribute(DataType="positiveInteger")] string pComponentType, string pPath, string pFilter, string pChangedAfter, [System.Xml.Serialization.SoapElementAttribute(DataType="positiveInteger")] string pFlags) { 
     object[] results = this.Invoke("TBusinessComponentGetContents", new object[] { 
        pSession, 
        pComponentType, 
        pPath, 
        pFilter, 
        pChangedAfter, 
        pFlags}); 
     return ((string)(results[0])); 
} 

的WSDL如下：

我的問題是：爲什麼會發生這種情況？參數不應該是整數，或者長整型值而不是字符串，因爲wsdl中的參數標記爲xsd：positiveInteger？我在這裏做錯了什麼？

謝謝！

這可能不是你想看到什麼，但是這可能會幫助：Microsoft

基本上它給了你與每個XSD數據類型相關的淨數據類型。在該頁面上，它將positiveInteger顯示爲一個字符串。所以，長話短說它正在做它應該做的事情。如果你真的想要一個數字數據類型，你可能想要使用一個無符號數據類型來代替正整數，如果你需要它永遠是積極的。否則，請使用適合您的xsd數據類型。因爲它看起來像你有控制Web服務和wsdl在c + +這應該不是太困難。如果這不是你想要做的事情，你可能需要在你的c＃客戶端上添加邏輯檢查，以確保你發送了一個數字。由於技術上所有東西都以xml字符串形式出現，所以技術上無關緊要，只要該服務可以正確地序列化您的請求即可。因此對您的消費者對象進行數據檢查。

在附註中，當我需要過去開發服務時，我們總是手工編寫xsd/wsdl契約，而不是讓工具生成它們，所以我們總是知道我們會得到什麼。不知道這是你做了什麼，但你也可以做到這一點。當我們這樣做時，我們使用wsdl工具生成服務器代理和客戶端代理，以便您可以在cpp中生成服務器端，在cs中生成客戶端，然後按照需要填寫內容。

希望可以幫助你。
