我到处找了,还没有找到我问题的答案。让我开门见山吧。我开发了一个android消息应用程序,用于实验C2DM。我的app获得了注册ID,并正确地显示在我的Log中。然后,我将该密钥发送到我的c# web服务。
c# Web服务然后申请一个验证令牌,它工作得很好。到目前为止还没有问题。但是,只要我发布我的主体项目(registration_id, collapse_key, data.<key>, delay_while_idle
)与我的标题(GoogleLogin auth=[AUTH_TOKEN])
,我得到response: "Error=InvalidRegistration".
没有理由不工作。是的,我已经尝试了所有可用的堆栈溢出解决方案,但仍然没有成功。以下是我的服务器端主代码:
WebRequest theRequest;
HttpWebResponse theResponse;
ArrayList theQueryData;
theRequest = WebRequest.Create("https://www.google.com/accounts/ClientLogin");
theRequest.Method = "POST";
theQueryData = new ArrayList();
String [] test = new String[5];
test[0] = "accountType=HOSTED_OR_GOOGLE";
test[1] = "Email=XXXXXXXXXXXXXXXXX";
test[2] = "Passwd=XXXXXXXXXXXXXXXX";
test[3] = "Source=Domokun";
test[4] = "service=ac2dm";
// Set the encoding type
theRequest.ContentType = "application/x-www-form-urlencoded";
// Build a string containing all the parameters
string Parameters = String.Join("&", (String[])test);
theRequest.ContentLength = Parameters.Length;
// We write the parameters into the request
StreamWriter sw = new StreamWriter(theRequest.GetRequestStream());
sw.Write(Parameters);
sw.Close();
// Execute the query
theResponse = (HttpWebResponse)theRequest.GetResponse();
StreamReader sr = new StreamReader(theResponse.GetResponseStream());
String value = sr.ReadToEnd();
String token = ParseForAuthTokenKey(value);
String value2 = "";
if (value != null)
{
WebRequest theRequest2;
HttpWebResponse theResponse2;
ArrayList theQueryData2;
theRequest2 = WebRequest.Create("http://android.clients.google.com/c2dm/send");
theRequest2.Method = "POST";
theQueryData2 = new ArrayList();
String[] test2 = new String[4];
test[0] = "registration_id=" + registerid;
test[1] = "collapse_key=0";
test[2] = "data.payload=Jannik was hier";
test[3] = "delay_while_idle=0";
// Set the encoding type
theRequest2.ContentType = "application/x-www-form-urlencoded";
// Build a string containing all the parameters
string Parameters2 = String.Join("&", (String[])test2);
theRequest2.ContentLength = Parameters2.Length;
theRequest2.Headers.Add(HttpRequestHeader.Authorization, "GoogleLogin auth=" + token);
// We write the parameters into the request
StreamWriter sw2 = new StreamWriter(theRequest2.GetRequestStream());
sw2.Write(Parameters2);
sw2.Close();
// Execute the query
theResponse2 = (HttpWebResponse)theRequest2.GetResponse();
StreamReader sr2= new StreamReader(theResponse2.GetResponseStream());
value2 = sr2.ReadToEnd();
public static bool RemoteCertificateValidationCallback(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
return true;
}
private static string ParseForAuthTokenKey(string webResponse)
{
string tokenKey = String.Empty;
if (webResponse.Contains(AuthTokenHeader))
{
tokenKey = webResponse.Substring(webResponse.IndexOf(AuthTokenHeader) + AuthTokenHeader.Length);
if (tokenKey.Contains(Environment.NewLine))
{
tokenKey.Substring(0, tokenKey.IndexOf(Environment.NewLine));
}
}
return tokenKey.Trim();
}
我能想到的就是我的C2DM账户没有正确注册。会是这样吗?还是我的代码中有我遗漏的错误?
OK。我找到解决办法了。
string requestBody = string.Format("registration_id={0}&collapse_key{1}&data.key=value",
HttpUtility.UrlEncode(registrationId), "collapse");
string responseBody = null;
WebHeaderCollection requestHeaders = new WebHeaderCollection();
WebHeaderCollection responseHeaders = null;
requestHeaders.Add(HttpRequestHeader.Authorization, string.Format("GoogleLogin auth={0}", authToken));
httpClient.DoPostWithHeaders(c2dmPushUrl,
requestBody,
"application/x-www-form-urlencoded",
out responseBody,
out responseHeaders,
requestHeaders);
public bool DoPostWithHeaders(string url,
string requestBody,
string contextType,
out string responseBody,
out WebHeaderCollection responseHeaders,
WebHeaderCollection requestHeaders = null)
{
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
// FIRST SET REQUEST HEADERS
httpWebRequest.Headers = requestHeaders;
httpWebRequest.Method = "POST";
// THEN SET CONTENT TYPE - THE ORDER IS IMPORTANT
httpWebRequest.ContentType = contextType;
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(requestBody);
httpWebRequest.ContentLength = data.Length;
stream = httpWebRequest.GetRequestStream();
stream.Write(data, 0, data.Length);
