API login
I am using swagger generated library and there seems to be no option available for basic auth.
yes.. there is no token..
I use codes below to get a device info..
hope you can improve it for your requirement
string url = "http://gps.mydomain.com:8082/api/devices?uniqueId=mydeviceId";
var pairs = new List<KeyValuePair<string, string>> { };
var byteArray = Encoding.ASCII.GetBytes("your_ID"+ ":" + "your_Password");
var client = new HttpClient();
client.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "application/json");
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var content = new FormUrlEncodedContent(pairs);
var response = client.GetAsync(url).Result;
HttpStatusCode statusCode = response.StatusCode;
switch (statusCode)
{
case HttpStatusCode.OK:
{
response.EnsureSuccessStatusCode();
string res = response.Content.ReadAsStringAsync().Result;
if (response.IsSuccessStatusCode)
{
JArray rows = JArray.Parse(res);
if (rows.HasValues)
{
foreach (JToken row in rows)
{
id = (int)row["id"];
positionId = (int)row["positionId"];
status = (string)row["status"];
groupId = (int)row["groupId"];
}
}
}
}
break;

}Thank you for sharing your code. I have managed to use the swagger library and implemented a gui interface with GMaps. Im getting the problem of fetching past positions of the devices.
I have very little experience with http. Can you please show me how to add parameters to httpclient class on c#. Example code would be really appreciated. Thank you
I use code below to get list of device positions..
to get its current position just add "&id=" at the end of the query string and pass positionid value..
hopefully someone here can improve it.. :)
string url = "http://gps.mydomain.com:8082/api/positions?deviceId=MYUNIQUEID&from=STARTDATE&to=ENDDATE";
var pairs = new List<KeyValuePair<string, string>> { };
var byteArray = Encoding.ASCII.GetBytes(GPSAccount_Id + ":" + GPSAccount_Password);
var client = new HttpClient();
client.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "application/json");
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var content = new FormUrlEncodedContent(pairs);
var response = client.GetAsync(url).Result;
HttpStatusCode statusCode = response.StatusCode;
switch (statusCode)
{
case HttpStatusCode.OK:
{
response.EnsureSuccessStatusCode();
string res = response.Content.ReadAsStringAsync().Result;
string status = string.Empty;
string message = string.Empty;
if (response.IsSuccessStatusCode)
{
JArray rows = JArray.Parse(res);
if (rows.HasValues)
{
try
{
foreach (JToken row in rows)
{
try
{
int id = (int)row["id"];
if (firstId == 0)
{ firstId = id; }
lastId = id;
string deviceid = (string)row["deviceid"];
string type = (string)row["type"];
string servertime = (string)row["serverTime"];
string devicetime = (string)row["deviceTime"];
string fixedtime = (string)row["fixTime"];
bool outdated = (bool)row["outdated"];
bool valid = (bool)row["valid"];
lat = (double)row["latitude"];
lng = (double)row["longitude"];
double alt = (double)row["altitude"];
double speed = (double)row["speed"];
double course = (double)row["course"];
address = (string)row["address"];
double accuracy = (double)row["accuracy"];
string network = (string)row["network"];
JObject objAttr = (JObject)row["attributes"];
if (objAttr.HasValues)
{
if (objAttr.ContainsKey("alarm"))
{ string alarm = (string)objAttr["alarm"]; }
distance = (double)objAttr["distance"];
double totaldistance = (double)objAttr["totalDistance"];
bool motion = (bool)objAttr["motion"];
}
}
catch { }
finally { }
}
}
catch { }
finally { }
ret = true;
}
}
}and dont forget to use ISO8601 format for 'from' and 'to'
Thank you. I will test the code.
Finally there is something that works. Thank you primtek for sharing your code.
I get syntax error at
if (objAttr.ContainsKey("alarm"))"JObject does not contain a definition for ContainsKey"
Hi..
make sure you use Newtonsoft.Json 11.0.0.0 or later
https://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_Linq_JObject.htm
string url = "http://demo3.traccar.org/api/session";
var pairs = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("email", "xyz@gmail.com"),
new KeyValuePair<string, string>("password", "*****")
};
var client = new HttpClient();
client.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "x-www-form-urlencoded");
var content = new FormUrlEncodedContent(pairs);
var response = client.PostAsync(url, content).Result;
HttpStatusCode statusCode = response.StatusCode;
if (statusCode== HttpStatusCode.OK)
{
try
{
response.EnsureSuccessStatusCode();
string res = response.Content.ReadAsStringAsync().Result;
HttpHeaders header = response.Headers;
if (response.IsSuccessStatusCode)
{
JObject objGPS = JObject.Parse(res);
if (objGPS.HasValues)
{
var User_Id = (int)objGPS["id"];
IEnumerable<string> headerValues = response.Headers.GetValues("set-cookie");
var User_Token = headerValues.FirstOrDefault();
}
}
}
catch (Exception e)
{
Console.WriteLine(e);
}
}to fetch token manually, let me know if i am wrong thank you!
Actually I want to make a windows 10 application for windows store. I will share it on github too. Your cooperation will he very helpful.
