[英]C# httpclient get response
I used httpClient to send data to the server. 我使用httpClient将数据发送到服务器。 I can check the response successfully, but my response string is in a php file. 我可以成功检查响应,但是响应字符串在php文件中。 I don't know how to access this string in php with something like: 我不知道如何用类似这样的方式在php中访问此字符串:
if user exist echo true;
else echo false;
I tried with WebClient class. 我尝试了WebClient类。 It worked but I was unable to check if it's response is successful. 它有效,但是我无法检查它的响应是否成功。
Here is the code: 这是代码:
public Boolean authorization(String korisnik, String zaporka)
{
var client = new HttpClient();
var pairs = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("korisnik", korisnik),
new KeyValuePair<string, string>("zaporka", zaporka)
};
var content = new FormUrlEncodedContent(pairs);
var response = client.PostAsync("http://www.etfos.unios.hr/~tsapina/autorizacija.php", content).Result;
System.Diagnostics.Debug.WriteLine(response);
if (response.IsSuccessStatusCode)
{
MessageBox.Show("success respond");
return false;
}
return true;
}
I need to get result in a php file output. 我需要在php文件输出中得到结果。
You want to check the Content
has value, then ReadAsStringAsync()
for the content. 您要检查Content
是否有值,然后检查Content
ReadAsStringAsync()
。 It's JSON though, so you'll need to parse it. 它是JSON,因此您需要对其进行解析。
Here, I use JsonConvert.Serialize<Dictionary<string,string>>()
from Json .NET to deserialize the JSON to a Dictionary<string, string>
object, which you can use to access the data. 在这里,我使用来自Json .NET的 JsonConvert.Serialize<Dictionary<string,string>>()
将JSON反序列化为Dictionary<string, string>
对象,您可以使用该对象访问数据。 May I also suggest using async
and await
to make use of asynchronous functions properly: 我还可以建议使用async
并await
正确使用异步函数:
public async bool Authorization(string korisnik, string zaporka){
...
try {
//will always throw an exception if not successful
response.EnsureSuccessStatusCode();
var response = await client.PostAsync("http://www.etfos.unios.hr/~tsapina/autorizacija.php", content);
if (httpResponse.Content != null) {
var responseContent = await httpResponse.Content.ReadAsStringAsync();
var dict = JsonConvert.DeserializeObject<Dictionary<string, string>>(responseContent);
Console.WriteLine(dict["post_var_key"]);
}
}
catch (Exception ex) {
Console.WriteLine("Error occured: " + ex.Message);
}
}
