Re: [WP8 ] POST 訊息到網頁
今天測試後又發現了一個狀況，如果送出的目標網址，只是單純回應訊息，
就可以正常回應，但是如果是要接受參數的網址，只要不是在本機的網站，
都會回應500。所以應該是MultipartFormDataContent我有漏了什麼設定，
導致目標網頁無法正常解析嗎?
以下這是我的作法
頁面程式碼
string url = "”;
MultipartFormDataContent param = new MultipartFormDataContent();
HttpContent loginContent = new StringContent(UserLogin.Text);
HttpContent PasswordContent = new StringContent(UserPwd.Text);
loginContent.Headers.ContentType = new
MediaTypeHeaderValue("application/x-www-form-urlencoded");
PasswordContent.Headers.ContentType = new
MediaTypeHeaderValue("application/x-www-form-urlencoded");
param.Add(loginContent, "login");
param.Add(PasswordContent, "Password");
string userdata = await Model.getRequest.PostDataToWeb(url,param);
PostDataToWeb函數如下
public static async Task<string> PostDataToWeb(string url,
MultipartFormDataContent content)
{
var tcs = new TaskCompletionSource<string>();
var httpClient = new HttpClient(new HttpClientHandler());
string responseString="";
try
{
HttpResponseMessage response = await httpClient.PostAsync(url, content);
response.EnsureSuccessStatusCode();
responseString = await response.Content.ReadAsStringAsync();
}
catch (Exception ex)
{
tcs.TrySetException(ex);
return ex.Message;
}
return responseString;
}

補一下我第一種方法~主要就是上色地方不同~也就是參數的建置方式
函式部分
public static async Task<string> PostDataToWeb(string url,
List<KeyValuePair<string, string>> content)
{
var tcs = new TaskCompletionSource<string>();
var httpClient = new HttpClient(new HttpClientHandler());
string responseString="";
try
{
HttpResponseMessage response = await
httpClient.PostAsync(url, new FormUrlEncodedContent(content));
response.EnsureSuccessStatusCode();
responseString = await response.Content.ReadAsStringAsync();
}
catch (Exception ex)
{
tcs.TrySetException(ex);
return ex.Message;
}
return responseString;
}
