Question

我继承了一个API，它给出了一个如何调用API的Visual Basic示例，如下所示：

Dim sPost As String
Dim sAction As String
Dim sXMLData As String
Dim sHTTPHeaders As String
sPost = "POST"
sAction = "http://MyHost/1/XmlService"
sXMLData = "<xml ..> <request …….. /></xml>"
sHTTPHeaders = "Content-type: text/xml"
Inet1.Execute sAction, sPost, sXMLData, sHTTPHeaders

我熟悉使用HttpWebRequest并没有设置内容类型，方法等问题，但我不知道如何设置sXMLData - 我将设置HttpWebRequest的哪个属性？

先谢谢。

Answer 1

您似乎希望将XML数据写入请求正文。为此，您通常使用HttpWebRequest.GetRequestStream()：

创建StreamWriter

// HttpWebRequest request;
// string sXmlData;

using (StreamWriter sw = new StreamWriter(request.GetRequestStream()))
{
    sw.Write(sXmlData);
}

Answer 2

应该像在UploadString上调用WebClient一样简单：

using (WebClient wc = new WebClient()) {
    wc.Headers[HttpRequestHeader.ContentType] = "text/xml";
    wc.UploadString(sAction, sXMLData); // (url, data) .. default method is POST
}

C＃相当于Visual Basic API调用
