[英]Translate a piece of PHP cURL code to C#
I'm trying to translate this piece of code written to fetch data from basis's website (the activity tracker). 我正在尝试翻译这段代码,以便从基准的网站(活动跟踪器)中获取数据。 The task I want to achieve here is to fetch the access_token returned in the Http response header.
我要在此处完成的任务是获取Http响应标头中返回的access_token。 There is no problem with the original PHP code, however, there are a few cUrl options I don't know how to map to C#'s WebClient implementation.
原始的PHP代码没有问题,但是,有一些cUrl选项我不知道如何映射到C#的WebClient实现。 These options include CURLOPT_RETURNTRANSFER, CURLOPT_FOLLOWLOCATION and CURLOPT_COOKIESESSION.
这些选项包括CURLOPT_RETURNTRANSFER,CURLOPT_FOLLOWLOCATION和CURLOPT_COOKIESESSION。
The detail problem is listed below, here is the piece of PhP code: 下面列出了详细问题,这是一段PhP代码:
$login_data = array(
'username' => $this->username,
'password' => $this->password,
);
// Initialize the cURL resource and make login request
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => 'https://app.mybasis.com/login',
CURLOPT_RETURNTRANSFER => false, //default: true
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $login_data,
CURLOPT_FOLLOWLOCATION => true, // defulat: true
CURLOPT_HEADER => 1,
CURLOPT_COOKIESESSION => true,
CURLOPT_COOKIEJAR => $this->cookie_jar
));
Using this code, the result would be: (which contains the access token I need) 使用此代码,结果将是:(其中包含我需要的访问令牌)

However, when I use C# WebClient to communicate with basis like below: 但是,当我使用C#WebClient与以下基础进行通信时:
var data = new NameValueCollection
{
{ "username", username},
{ "password", password},
};
HttpWebResponse response = client.UploadValues("https://app.mybasis.com/login", "POST", data);
foreach (string name in client.ResponseHeaders.Keys)
{
Console.WriteLine(name+"="+client.ResponseHeaders[name]);
}
I could only get this: 我只能得到这个:

as response. 作为回应。
Does anyone know why I cannot get the first two Http responses but the third one only? 有谁知道为什么我不能获得前两个Http响应,而只有第三个?
In order to get the functionality out of C# you are looking for you need to use the Http web Request API within the .NET framework. 为了获得C#的功能,您需要在.NET框架中使用Http Web Request API。 It should provide the capability you are looking for.
它应该提供您正在寻找的功能。
I did the same thing but used the 4.5 HttpClient 我做了同样的事情,但使用了4.5 HttpClient
CookieContainer cookies = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;
HttpClient client = new HttpClient(handler);
// Create the HttpContent for the form to be posted.
var requestContent = new FormUrlEncodedContent(new[] {
new KeyValuePair<string, string>("username", "***"),
new KeyValuePair<string, string>("password", "***"),
});
// Get the response.
HttpResponseMessage response = await client.PostAsync(
"https://app.mybasis.com/login",
requestContent);
// Get the response content.
HttpContent responseContent = response.Content;
Uri uri = new Uri("https://app.mybasis.com/login");
IEnumerable<Cookie> responseCookies = cookies.GetCookies(uri).Cast<Cookie>();
foreach (Cookie cookie in responseCookies)
Console.WriteLine(cookie.Name + ": " + cookie.Value);
