问题描述
web service post方法对我来说是新的。可以帮我处理错误。
web service post method is new for me. can u pls help me out what am i doing wrong.
WebClient webClient = new WebClient();
webClient.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
webClient.Encoding = Encoding.UTF8;
webClient.UploadStringCompleted += new UploadStringCompletedEventHandler((sender, e) =>
{
if (e.Error != null)
{
return;
}
string result = e.Result;
});
string uri = "http://localhost:60696/service/getlogin/";
StringBuilder postData = new StringBuilder();
postData.AppendFormat("/{0}/{1}", "username", HttpUtility.UrlEncode(textBox1.Text));
postData.AppendFormat("/{0}/{1}", "password", HttpUtility.UrlEncode(textBox2.Text));
webClient.Headers[HttpRequestHeader.ContentLength] = postData.Length.ToString();
webClient.UploadStringAsync(new Uri(uri, UriKind.RelativeOrAbsolute),"POST", postData.ToString());
顺便说一下,如果我访问带有参数和值的URL附加它的工作正常
by the way, If i access the url with the parameters and value appended its working fine
像这样(http:// localhost:60696 / service / getlogin / username,123,password,456)。
推荐答案
postdata似乎错误编码,应该是这样:
The postdata seems wrongly encoded, should be something like this:
postData.AppendFormat("{0}={1}", "username", HttpUtility.UrlEncode(textBox1.Text));
postData.AppendFormat("&{0}={1}", "password", HttpUtility.UrlEncode(textBox2.Text));
