我需要序列化一个 XML 以附加到 API PUT 请求。
我正在使用 System.Xml.Serialization.
最终结果需要类似于以下内容:
<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
<product>
<id>

</name>
</product>
</prestashop>
为此,我有一个这样的课程:
[XmlType("product")]
public class Product
{
public Product()
{
id = "";
active = "1";
available_for_order= "1";
indexed= "1";
visibility = "both";
delivery_in_stock = new List<PaLanguage>();
delivery_out_stock = new List<PaLanguage>();
name = new List<PaLanguage>();
}
[XmlElement("id")] public XmlCDataSection C_id { get { return new XmlDocument().CreateCDataSection(id); } set { id = value.Value; } }
[XmlIgnore] public string id;
[XmlElement("cache_default_attribute")] public XmlCDataSection C_cache_default_attribute { get { return new XmlDocument().CreateCDataSection(cache_default_attribute); } set {cache_default_attribute = value.Value; } }
[XmlIgnore] public string cache_default_attribute;
...
[XmlArray("delivery_in_stock")] public List<PaLanguage> delivery_in_stock;
[XmlArray("delivery_out_stock")] public List<PaLanguage> delivery_out_stock;
...
PaLanguage 是:
public class PaLanguage
{
[XmlElement("language")] public XmlCDataSection C_language { get { return new XmlDocument().CreateCDataSection(language); } set { language = value.Value; } }
[XmlIgnore] public string language { get; set; }
[XmlAttribute("id")] public string id;
}
因为这是更新记录,所以我首先完成一个获取请求,然后匹配它的所有值。 我使用以下代码完成此操作:
XDocument getResponse = Helper.GetProductReference(get, Helper.GetValueByKey("ShopApi") + "products/");
var gotProduct = getResponse
.Element("prestashop")
.Element("products")
.Elements("product")
.Where(e => e.Element("reference").Value == mtrl)
.Single();
我创建了一个新的产品项附加到我的放置请求,但我在序列化它的 XmlArrays 时遇到了问题。
我尝试的最后一件事是:
foreach (XElement x in gotProduct.Element("delivery_in_stock").Elements("language"))
{
product.delivery_in_stock.Add(new PrestaLanguage { id = (string)x.Attribute("id"), language = (string)x.Element("language") });
}
这是完全错误的,因为它将它序列化为:
<product>
<id><![CDATA[2678]]></id>
... xml
<delivery_in_stock>
<PaLanguage id="1">
<language><![CDATA[]]></language>
</PaLanguage>
<PaLanguage id="2">
<language><![CDATA[]]></language>
</PaLanguage>
</delivery_in_stock>
感觉就像我已经尝试了所有可以在网上和官方文档中找到的东西,每次尝试都离我的预期结果更远。
我应该注意到这个类实际上还有几十个字段,它们要么只是一个字符串,要么是 id 和语言值的另一种组合。
感谢任何帮助。
似乎 XML 中的 delivery_in_stock 和 delivery_out_stock 元素可以包含具有不同 id 属性的多个语言元素。因此,您需要修改您的 foreach 循环以处理多种语言元素。
您可以使用 Descendants("language") 而不是使用 Elements("language") 来获取 delivery_in_stock 和 delivery_out_stock 下的所有语言元素。
foreach (XElement x in gotProduct.Element("delivery_in_stock").Descendants("language"))
{
product.delivery_in_stock.Add(new PaLanguage { id = (string)x.Attribute("id"), language = (string)x });
}
foreach (XElement x in gotProduct.Element("delivery_out_stock").Descendants("language"))
{
product.delivery_out_stock.Add(new PaLanguage { id = (string)x.Attribute("id"), language = (string)x });
}
此外,在 PaLanguage 类中,语言属性应该是 XmlCDataSection 类型,而不是字符串,因为它包含 CDATA。
public class PaLanguage
{
[XmlText]
public XmlCDataSection language { get; set; }
[XmlAttribute("id")]
public string id { get; set; }
}
最后是product类,应该给没有的properties加上[XmlElement]属性,比如id_shop_default, reference, supplier_reference等
[XmlType("product")]
public class Product
{
public Product()
{
id = "";
active = "1";
available_for_order = "1";
indexed = "1";
visibility = "both";
delivery_in_stock = new List<PaLanguage>();
delivery_out_stock = new List<PaLanguage>();
name = new List<PaLanguage>();
}
[XmlElement("id")]
public XmlCDataSection C_id { get { return new XmlDocument().CreateCDataSection(id); } set { id = value.Value; } }
[XmlElement("cache_default_attribute")]
public XmlCDataSection C_cache_default_attribute { get { return new XmlDocument().CreateCDataSection(cache_default_attribute); } set { cache_default_attribute = value.Value; } }
[XmlElement("id_shop_default")]
public XmlCDataSection C_id_shop_default { get { return new XmlDocument().CreateCDataSection(id_shop_default); } set { id_shop_default = value.Value; } }
[XmlElement("reference")]
public XmlCDataSection C_reference { get { return new XmlDocument().CreateCDataSection(reference); } set { reference = value.Value; } }
[XmlElement("supplier_reference")]
public XmlCDataSection C_supplier_reference { get { return new XmlDocument().CreateCDataSection(supplier_reference); } set { supplier_reference = value.Value; } }
[XmlElement("location")]
public XmlCDataSection C_location { get { return new XmlDocument().CreateCDataSection(location); } set { location = value.Value; } }
[XmlElement("width")]
public XmlCDataSection C_width { get { return new XmlDocument().CreateCDataSection(width); } set { width = value.Value; } }
[XmlElement("height")]
public XmlCDataSection C_height { get { return new XmlDocument().CreateCDataSection(height); } set { height = value.Value; } }
// etc..
