On a Solr instance I can get the status with this command: bin/solr status
Is there a way to get the status using SolrNet? Sometimes I need to import a lot of data and I would like halt the import if the heap size is >= 80%
Example query to get the status
http://my-solr.bigboss.com/solr/admin/collections?_=1573650195955&action=CLUSTERSTATUS&wt=json
http://my-solr.bigboss.com/solr/admin/info/system?_=1573650195955&nodes=10.0.1.138:8983_solr,10.0.1.232:8983_solr,10.0.5.244:8983_solr&wt=json
I am now using httpClient but are still interested if this can be done with SolrNet
private List<string> GetSolrNodes()
{
using (var httpClient = new HttpClient())
{
httpClient.Timeout = TimeSpan.FromSeconds(20);
var url = _solrBaseUrl + "admin/collections?action=CLUSTERSTATUS&wt=json";
var json = httpClient.GetStringAsync(url).Result;
var obj = JObject.Parse(json);
var liveNodes = (JArray)obj["cluster"]["live_nodes"];
return liveNodes.HasValues ? liveNodes.Select(liveNode => liveNode.ToString()).ToList() : new List<string>();
}
}
private int GetSolrNodeWithMaxHeapSize()
{
var nodes = GetSolrNodes();
using (var httpClient = new HttpClient())
{
httpClient.Timeout = TimeSpan.FromSeconds(20);
var stringNodes = nodes.Join(",");
var url = _solrBaseUrl + $"admin/info/system?nodes={stringNodes}&wt=json";
var json = httpClient.GetStringAsync(url).Result;
var obj = JObject.Parse(json);
return nodes.Select(node => (int) obj[node]["jvm"]["memory"]["raw"]["used%"]).Concat(new[] {0}).Max();
}
}

I tried to send an api call to the identity server via .net 6 console application.
Here is the request:
public static async Task<WorkflowResponse> PostRequestToIdentityAsync()
{
var url = "http://didentity/connect/token";
IdentityRequestDataVM identityRequestDataVM = new IdentityRequestDataVM();
identityRequestDataVM.username = "csm";
identityRequestDataVM.password = "MjAyMjox";
identityRequestDataVM.grant_type = "password";
identityRequestDataVM.scope = "m_gln m_msd";
string jsonString = JsonConvert.SerializeObject(identityRequestDataVM);
using (var httpClient = new HttpClient())
{
var request = new HttpRequestMessage
{
Method = HttpMethod.Post,
RequestUri = new Uri(url),
Content = new StringContent(jsonString),
Headers =
{
{"X-Login","override"}
}
};
var user = "gclt";
var password = "glsrt";
request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
request.Headers.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes($"{user}:{password}")));
HttpResponseMessage message = await httpClient.SendAsync(request);
if (message.StatusCode == System.Net.HttpStatusCode.OK)
{
var contents = await message.Content.ReadAsStringAsync();
WorkflowResponse workflowResponse = JsonConvert.DeserializeObject<WorkflowResponse>(contents);
return workflowResponse;
}
else
{
throw new Exception(await message.Content.ReadAsStringAsync());
}
}
}
But, it returned 400 err code (Bad request), is there any mistake in the code snippet ?
It is working fine with postman.
I have a Encoded string like this:
https://xx.yyy.ir/xx/ff/addUser?name=%d8%b3%d9%84%d8%a7%d9%85
But when I use Uri to convert it to a URL and send it
result = "https://xx.yyy.ir/xx/ff/addUser?name=%d8%b3%d9%84%d8%a7%d9%85"
var client = new HttpClient
{
BaseAddress = new Uri(result.ToString()),
};
var response = await client.GetAsync("");
it send this request :
https://xx.yyy.ir/xx/ff/addUser?name=سلام
why this happen? how to prevent from this?
This is what's causing your problem: new Uri(result.ToString())
Let's try to do this in a proper manner and see what happens.
var builder = new UriBuilder("https://xx.yyy.ir/xx/ff/addUser") { Port = -1 };
var query = HttpUtility.ParseQueryString(builder.Query);
query["name"] = "سلام";
builder.Query = query.ToString();
using var httpClient = new HttpClient();
var response = await client.GetAsync(builder.ToString());
builder.ToString() returns https://xx.yyy.ir/xx/ff/addUser?name=%d8%b3%d9%84%d8%a7%d9%85
So basically, the above code boils down to this:
using var httpClient = new HttpClient();
var response = await client.GetAsync("https://xx.yyy.ir/xx/ff/addUser?name=%d8%b3%d9%84%d8%a7%d9%85");
Tested and verified on my computer.
I have little problem with using Cloudinary, I can upload the images it works fine but I guess i cant get any response from Cloudinary. Suggestion? about required parameters
Handler
public async Task<Photo> Handle(Command request, CancellationToken cancellationToken)
{
var photoUploadResult = _photoAccessor.AddPhoto(request.File);
var photo = new Photo
{
Url = photoUploadResult.Url,
Id = photoUploadResult.PublicId
};
var success = await _context.SaveChangesAsync() > 0;
if (success) return photo;
throw new Exception("Problem saving changes");
}
Accessor
public PhotoUploadResult AddPhoto(IFormFile file)
{
var uploadResult = new ImageUploadResult();
if (file.Length > 0)
{
using (var stream = file.OpenReadStream())
{
var uploadParams = new ImageUploadParams
{
File = new FileDescription(file.FileName, stream)
};
uploadResult = _cloudinary.Upload(uploadParams);
}
}
if (uploadResult.Error != null)
throw new Exception(uploadResult.Error.Message);
return new PhotoUploadResult
{
PublicId = uploadResult.PublicId,
Url = uploadResult.SecureUri.AbsoluteUri
};
}
What do you get in response? Can you try:
string cloud_name = "<Cloud Name>";
string ApiKey = "<Api-Key>";
string ApiSecret = "<Api-Secret>";
Account account = new Account(cloud_name,ApiKey,ApiSecret);
Cloudinary cloudinary = new Cloudinary(account);
cloudinary.Api.Timeout = int.MaxValue;
var ImguploadParams = new ImageUploadParams()
{
File = new FileDescription(#"http://res.cloudinary.com/demo/image/upload/couple.jpg"),
PublicId = "sample",
Invalidate = true,
Overwrite = true
};
var ImguploadResult = cloudinary.Upload(ImguploadParams);
Console.WriteLine(ImguploadResult.SecureUri);
I'm trying to make chat app with XamarinForms and I'm trying to upload a file with parameters to server. But I'm getting always 403 Forbidden message. (There is no authentication, there is only token key for now).
If I try to get or send any data to server, it works as well. When I try to send a file with data it returns 403 Forbidden message. I also tried to send same data with Postman. it's worked as well. I'm writing part of code, Could you please tell me, I made it wrong where?
Thanks in advance.
private async Task<HttpClient> GetClient()
{
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add("Accept", "application/json");
client.DefaultRequestHeaders.Add("X-Token-Key", ServiceToken);
client.DefaultRequestHeaders.UserAgent.Add(new System.Net.Http.Headers.ProductInfoHeaderValue("Chrome", "41.0.2228.0"));
return client;
}
If I send text message, it works as well.
public async Task<MobileResult> SendConversationTextMessage(MessageModel message)
{
HttpClient client = await GetClient();
string param = JsonConvert.SerializeObject(message);
var response = await client.PostAsync(Url + "conversation/message_add_text", new StringContent(param, Encoding.UTF8, "application/json"));
var mobileResult = JsonConvert.DeserializeObject<MobileResult>(await response.Content.ReadAsStringAsync());
return mobileResult;
}
If I send message with data, it returns 403 Forbidden
public async Task<MobileResult> SendConversationFileMessage(
FileModel FileMessage,
int UserRemoteId,
int ConversationId,
int ToUserId,
string SendedTime,
MessageModel.MessageType Type,
MessageModel.MessageStatus Status,
string MessageType)
{
HttpClient client = await GetClient();
string PostUrl = Url + "conversation/message_add_" + MessageType;
MultipartFormDataContent content = new MultipartFormDataContent();
ByteArrayContent baContent = new ByteArrayContent(FileMessage.BinaryData);
StringContent UserIdContent = new StringContent(UserRemoteId.ToString());
StringContent ConversationIdContent = new StringContent(ConversationId.ToString());
StringContent ToUserIdContent = new StringContent(ToUserId.ToString());
StringContent SendedTimeContent = new StringContent(SendedTime.ToString());
StringContent TypeContent = new StringContent(Type.ToString());
StringContent StatusContent = new StringContent(Status.ToString());
content.Add(baContent, "AttachedFile", FileMessage.Name);
content.Add(UserIdContent, "serId");
content.Add(ConversationIdContent, "ConversationId");
content.Add(ToUserIdContent, "ToUserId");
content.Add(SendedTimeContent, "SendedTime");
content.Add(TypeContent, "Type");
content.Add(StatusContent, "Status");
try
{
var response = await client.PostAsync(PostUrl, content);
string result = await response.Content.ReadAsStringAsync();
var mobileResult = JsonConvert.DeserializeObject<MobileResult>(result);
return mobileResult;
}
catch (Exception e)
{
return new MobileResult
{
Result = false,
Data = null,
Message = e.ToString()
};
}
}
Postman-Screenshot
Edit: I've tested to send multipart/form-data different way but result is same I'm writing below code:
MultipartFormDataContent content = new MultipartFormDataContent();
var UserIdContent = new StringContent(UserId.ToString());
UserIdContent.Headers.Add("Content-Disposition", "form-data; name=\"UserId\"");
UserIdContent.Headers.Remove("Content-Type");
content.Add(UserIdContent, "UserId");
var ConversationIdContent = new StringContent(ConversationId.ToString());
ConversationIdContent.Headers.Add("Content-Disposition", "form-data; name=\"ConversationId\"");
ConversationIdContent.Headers.Remove("Content-Type");
content.Add(ConversationIdContent, "ConversationId");
var ToUserIdContent = new StringContent(ToUserId.ToString());
ToUserIdContent.Headers.Add("Content-Disposition", "form-data; name=\"ToUserId\"");
ToUserIdContent.Headers.Remove("Content-Type");
content.Add(ToUserIdContent, "ToUserId");
var SendedTimeContent = new StringContent(SendedTime.ToString());
SendedTimeContent.Headers.Add("Content-Disposition", "form-data; name=\"SendedTime\"");
SendedTimeContent.Headers.Remove("Content-Type");
content.Add(SendedTimeContent, "SendedTime");
var TypeContent = new StringContent(Type.ToString());
TypeContent.Headers.Add("Content-Disposition", "form-data; name=\"Type\"");
TypeContent.Headers.Remove("Content-Type");
content.Add(TypeContent, "Type");
var StatusContent = new StringContent(Status.ToString());
StatusContent.Headers.Add("Content-Disposition", "form-data; name=\"Status\"");
StatusContent.Headers.Remove("Content-Type");
content.Add(StatusContent, "Status");
var streamContent = new StreamContent(file.InputStream);
streamContent.Headers.Add("Content-Disposition", "form-data; name=\"AttachedFile\"; filename=\"" + file.FileName + "\"");
streamContent.Headers.Add("Content-Type", "video/mp4");
content.Add(streamContent, "AttachedFile", file.FileName);
Bellow is my code
public async void TestLoops(long device, double date1, double date2)
{
var connectionString = "mongodb://localhost.:27017";//Connection string
MongoClientSettings settings1 = MongoClientSettings.FromUrl(new MongoUrl(connectionString));// Set Url to the MongoClient
//MongoS
// MongoClient mongoClient = new MongoClient(settings1);
var client = new MongoClient(new MongoClientSettings
{
Server = new MongoServerAddress("connectionString"),
ClusterConfigurator = builder =>
{
builder.ConfigureCluster(settings => settings.With(serverSelectionTimeout: TimeSpan.FromSeconds(1000)));
}
});
//Server s = new MongoServerAddress(connectionString);
var db = client.GetDatabase("tracking");//Specifing the Database name
var user = db.GetCollection<BsonDocument>("location");//Specifing t
var builder1 = Builders<BsonDocument>.Filter;
// var builder1 = Builders<BsonDocument>.Filter;
//int
var filt = builder1.Eq("device", device) & builder1.Gte("timestamp", date1) & builder1.Lte("timestamp", date2);
//var filter = builder1.Eq("device", 358740050124519);
var data = user.Find(filt).Count();
lblmsg.Text = data.ToString();
}
when i write the var data = user.Find(filt); it works fine
You can do
var collection = database.GetCollection<Type>("DBName");
var cursor = collection.Find(Query.EQ("FieldToMatch" : "ValueToMatch"));
var count = cursor.Count();
another approach
db.collection.CountAsync(); // you can pass new BsonDocument() or a condition to countAsync based on your requirement.
