我在datacontract中有一个字符串数组,如下所示
[DataMember(Name = "photos", IsRequired = true, Order = 3)]
public string[] photos { get; set; }
在WCF REST服务调用中,我传递的是此字符串数组
的xml输入<photos>
<string>http://localhost:13169/MainPortal/ContentLibrary/21/58/1227132014-bmw-x1_100426158_m.jpg</string>
<string>http://localhost:13169/MainPortal/ContentLibrary/21/58/122713bmw2.jpg</string>
<string>http://localhost:13169/MainPortal/ContentLibrary/21/58/122713bmw3.jpg</string>
<string>http://localhost:13169/MainPortal/ContentLibrary/21/58/122713BMW_Hamann_Laguna_Seca.jpg</string><string>http://localhost:13169/MainPortal/ContentLibrary/21/58/1227132014-BMW-X1-SUV-sDrive-28i-4dr-4x2-Sports-Activity-Vehicle-Exterior-2.png</string>
</photos>
我的客户端代码能够通过在HttpWebRequest中传递xml来进行WebService调用而没有任何问题,从服务中我可以看到除了这个字符串数组之外的所有其他数据。我在DataContract中遗漏了一些序列化数组的东西。请帮忙
尝试使用CollectionDataContract,但仍然没有运气
[CollectionDataContract(Name = "photos")]
public class Photos : Collection<string>
还添加了KnownTypes,但序号类型
不需要[KnownType(typeof(string[]))]
public class PublishPhotos
{
这是完整的数据合同类
[DataContract(Namespace = "http://myurl.com/Publisher")]
[KnownType(typeof(string[]))]
public class PublishPhotos
{
[DataMember(Name = "publicationId", IsRequired = true, Order = 0)]
public int publicationId { get; set; }
[DataMember(Name = "issueId", IsRequired = true, Order = 1)]
public string issueId { get; set; }
[DataMember(Name = "contentId", IsRequired = true, Order = 2)]
public string contentId { get; set; }
[DataMember(Name = "photos", IsRequired = true, Order = 3)]
public Photos photos { get; set; }
}
答案 0 :(得分:1)
最后我弄清楚HttpWebRequest中的XML出了什么问题,问题在于序列化字符串数组。我可以通过访问/PublisherSvc.svc/help获取字符串的最简单方法,它需要名称空间http://schemas.microsoft.com/2003/10/Serialization/Arrays,如下所示
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">http://localhost:8081/photos/1/1.jpg</string>
希望这可以帮助面临类似问题的人

我已经找到了这个问题的答案。感谢@HarlanB
我已将数据合同从DataContract Serialization更改为XmlSerialization
[SerializableAttribute()]
[XmlTypeAttribute(AnonymousType = true)]
[XmlRootAttribute(Namespace = "http://myUrl.com/Publisher", IsNullable = false)]
public class PublishPhotos
{
//[DataMember(Name = "publicationId", IsRequired = true, Order = 0)]
[XmlElementAttribute(ElementName="publicationId", Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 0)]
public int publicationId { get; set; }
//[DataMember(Name = "issueId", IsRequired = true, Order = 1)]
[XmlElementAttribute(ElementName = "issueId", Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 1)]
public string issueId { get; set; }
//[DataMember(Name = "contentId", IsRequired = true, Order = 2)]
[XmlElementAttribute(ElementName = "contentId", Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 2)]
public string contentId { get; set; }
//[DataMember(Name = "photos", IsRequired = true, Order = 3)]
[XmlElementAttribute(ElementName = "photos", Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 3)]
public string[] photos { get; set; }
}
在客户端代码中,我使用XmlSerializer写入HttpWebRequest,如下所示
pubPhotos.publicationId = Convert.ToInt32(publication.Value);
pubPhotos.issueId = secName;
pubPhotos.contentId = selectedMediaItem;
HtmlDocument divDoc = new HtmlDocument();
divDoc.LoadHtml(widgetScript);
HtmlNode divNode = divDoc.DocumentNode.FirstChild;
HtmlNodeCollection imgs = divNode.SelectNodes("//img");
Collection<string> photos = new Collection<string>();
foreach (HtmlNode img in imgs)
{
photos.Add(img.Attributes["src"].Value);
}
pubPhotos.photos = photos.ToArray();
HttpWebRequest req = null;
const string url = "http://localhost:40009/PublisherSvc.svc/PublishPhotos";
req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "POST";
req.ContentType = "application/xml; charset=utf-8";
req.KeepAlive = false;
req.Timeout = 30000;
req.Headers.Add("SOAPAction", url);
XmlSerializer serilizer = new XmlSerializer(typeof(PublishPhotos));
var sw = new StreamWriter(req.GetRequestStream());
serilizer.Serialize(sw, pubPhotos);
sw.Close();
我希望这可以帮助那些有类似问题的其他人。
