我正在尝试使用.NET类而不是curl命令行复制Couch数据库。我之前从未使用过WebRequest或Httpwebrequest,但我试图用它们来发布下面的脚本请求。
这是couchdb复制的JSON脚本(我知道这有效):
{ ""_id"":"database_replicate8/7/12", "source":sourcedb, ""target"":"targetDB", ""create_target"":true, ""user_ctx"": { ""roles"": ["myrole"] } }
将上述脚本放入文本文件sourcefile.txt中。我想采用这一行,并使用.NET功能将其置于POST Web请求中。
在研究之后,我选择使用httpwebrequest类。以下是我到目前为止 - 我从http://msdn.microsoft.com/en-us/library/debx8sh9.aspx
得到了这个 HttpWebRequest bob = (HttpWebRequest)WebRequest.Create("sourceDBURL");
bob.Method = "POST";
bob.ContentType = "application/json";
byte[] bytearray = File.ReadAllBytes(@"sourcefile.txt");
Stream datastream = bob.GetRequestStream();
datastream.Write(bytearray, 0, bytearray.Length);
datastream.Close();
我是否正确地解决了这个问题?我对网络技术比较陌生,还在学习http调用的工作原理。
答案 0 :(得分:0)
这是我用来创建POST请求的方法:
private static HttpWebRequest createNewPostRequest(string apikey, string secretkey, string endpoint)
{
HttpWebRequest request = WebRequest.Create(endpoint) as HttpWebRequest;
request.Proxy = null;
request.Method = "POST";
//Specify the xml/Json content types that are acceptable.
request.ContentType = "application/xml";
request.Accept = "application/xml";
//Attach authorization information
request.Headers.Add("Authorization", apikey);
request.Headers.Add("Secretkey", secretkey);
return request;
}
在我的主要方法中,我称之为:
HttpWebRequest request = createNewPostRequest(apikey, secretkey, endpoint);
然后我将数据传递给这样的方法:
string requestBody = SerializeToString(requestObj);
byte[] byteStr = Encoding.UTF8.GetBytes(requestBody);
request.ContentLength = byteStr.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(byteStr, 0, byteStr.Length);
}
//Parse the response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
//Business error
if (response.StatusCode != HttpStatusCode.OK)
{
Console.WriteLine(string.Format("Error: response status code is{0}, at time:{1}", response.StatusCode, DateTime.Now.ToString()));
return "error";
}
else if (response.StatusCode == HttpStatusCode.OK)//Success
{
using (Stream respStream = response.GetResponseStream())
{
XmlSerializer serializer = new XmlSerializer(typeof(SubmitReportResponse));
reportReq = serializer.Deserialize(respStream) as SubmitReportResponse;
}
}
...
在我的情况下,我从一个类中序列化/反序列化我的身体 - 你需要改变它以使用你的文本文件。如果您想轻松删除解决方案,请将SerializetoString
方法更改为将文本文件加载到字符串的方法。
