我正在尝试使用REST API来通过httpclient获取数据,遇到解析问题,{“第1行第95位错误。期望来自名称空间'http://schemas.datacontract.org/2004/07/'的元素'workflow'。.遇到名称为'workflow的'Element' ',名称空间“。”}
客户端代码是
string baseUri = "/rest/workflows/";
client = CreateClient(baseUri);
HttpRequestMessage request = CreateRequest(baseUri);
var task = client.SendAsync(request);
HttpResponseMessage response = task.Result;
response.EnsureSuccessStatusCode();
response.Content.ReadAsAsync<collection>().ContinueWith(wf =>
{
Console.WriteLine(wf.Result.workflow.Length);
});
数据类
/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.17929")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://www.w3.org/2005/Atom", IsNullable = false)]
public partial class collection
{
private workflow[] workflowField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("workflow", Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public workflow[] workflow
{
get
{
return this.workflowField;
}
set
{
this.workflowField = value;
}
}
}
并且响应xml文件是这种格式
<collection xmlns:ns2="http://www.w3.org/2005/Atom">
<workflow uuid="5ffbde8c-c430-4851-9c83-164c102a4d68">
<name>Remove a Volume</name>
<categories>
<category>Decommissioning</category>
</categories>
</workflow>
</collection>
我可以通过使用response.Content.ReadAsStringAsync()来获取字符串并将其保存到xml文件中,然后,我将其反序列化为集合,可以成功,但是需要serizliazer的默认名称空间
XmlSerializer serializer = new XmlSerializer(typeof(collection), "xmlns:ns2=\"http://www.w3.org/2005/Atom\"");
c = serializer.Deserialize(stream) as collection;
任何人都可以为此提供帮助
最佳答案
您不应触摸从xsd.exe工具生成的文件。
只需通过设置XmlSerializer
显式设置您要使用DataContractSerializer
而不是默认使用XmlMediaTypeFormatter
的UseXmlSerializer = true
。
因此,您必须创建一个特定的类型格式化程序,如下所示:
var formatters = new List<MediaTypeFormatter>() {
new XmlMediaTypeFormatter(){ UseXmlSerializer = true } };
并将其用作
ReadAsAsync
方法的参数:private async Task<T> ReadAsync<T>(HttpResponseMessage response)
=> await response.Content.ReadAsAsync<T>(formatters);
