我使用Xamarin表单中的HttpClient在文本文件中包含的XML数据下方发布到URL。
1）此文本文件ReqSAML.txt存储在PCL Project中
<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope"
xmlns:a="http://www.w3.org/2005/08/addressing"
xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<s:Header>
....
.....
</s:Envelope>
2）我使用下面的代码来获取文件并将XML内容发布到基于Https的URL
string strURL = "https://adfs.xxx.com/adfs/services/trust/userxxxxxx";
var client = new System.Net.Http.HttpClient();
var assembly = typeof(MainPage).GetTypeInfo().Assembly;
Stream stream = assembly.GetManifestResourceStream("ReqSAML.txt");
string strXML = "";
string contentType = "application/soap+xml";
using (var reader = new System.IO.StreamReader(stream))
{
strXML = reader.ReadToEnd();
}
var content = new StringContent(strXML, Encoding.UTF8, contentType);
var targetUri = new Uri(strURL);
var resp = await client.PostAsync(targetUri, content);
var soapResp = resp.Content.ReadAsStringAsync();
以上代码是否正确用于在HttpClient中发布XML数据？ contentType是application / soap + xml
遇到麻烦了：
