I am trying to connect to a socket using a client that is running Tkinter. The script runs a banking app allowing users to log in. The user data is stored in an SQLite database. When running the socket and client scripts the Tkinter window launches and the user is able to log in. However, when the user logs out and tries to log in as another user the program gets stuck.
LogInCommand() I think is getting stuck as it only fails when running again. I believe it has to do with how I am discounting from the socket. However, I need the socket to constantly run for the app to work.
Socket :
import socket
import sqlite3
Connection = sqlite3.connect('BankAccounts.sqlite')
st = socket.socket() #Creating a socket object. Second socket is the class.
print("socket ready")
st.bind(("Localhost",8080)) #Creating the socket using port 8080 (IP address + port number)
st.listen(100) #Only allowing a maximum of two connections at a time.
print("waiting for connections")
while True:
Client, address = st.accept() #Creating two variables and setting them equal to the accept object method.
# print("connected with", address)
print("Banking")
cdata = Client.recv(1024).decode()
print("in loop")
if not cdata:
break
if "*li#" in cdata:
print(cdata)
data = cdata.split("*li#")
cred = data[1].split("##")
sql = "SELECT * FROM bankusers"
curser = Connection.execute(sql)
username = cred[0]
password = cred[1]
for row in curser:
if row[0] == username and row[1] == password:
balance = str(row[2])
print(type(balance))

I'm trying to create a subscription to the callRecords notifications with Graph API in R. I'm looking at this Microsoft page as a reference: https://learn.microsoft.com/en-us/graph/api/subscription-post-subscriptions?view=graph-rest-beta&tabs=http
Here is my code:
Subscribtion_Call <- AzureGraph::call_graph_endpoint(Tok, options = list(), api_version = Version, operation = "subscriptions", content_type = "application/json")
Subscription_Properties <- list(
changeType = "created,updated",
notificationUrl = "https://webhook.azurewebsites.net/notificationClient",
resource = "communications/callRecords",
expirationDateTime = "2022-04-09T11:00:00.0000000Z",
clientState = "SecretClientState"
)
Send_Subscription <- call_graph_url(Tok, Endpoint, body = Subscription_Properties, encode = "json",
content_type = "application/json",
http_verb = "POST",
http_status_handler = "message",
simplify = FALSE,
auto_refresh = TRUE
)
This gets me an HTTP 405 error as below:
> Subscribtion_Call <- AzureGraph::call_graph_endpoint(Tok, options = list(), api_version = Version, operation = "subscriptions", content_type = "application/json")
>
> Subscription_Properties <- list(
+ changeType = "created,updated",
+ notificationUrl = "https://webhook.azurewebsites.net/notificationClient",
+ resource = "communications/callRecords",
+ expirationDateTime = "2022-04-09T11:00:00.0000000Z",
+ clientState = "SecretClientState"
+ )

+ content_type = "application/json",
+ http_verb = "POST",
+ http_status_handler = "message",
+ simplify = FALSE,
+ auto_refresh = TRUE
+ )
Method Not Allowed (HTTP 405). Failed to complete operation. Message:

If I change the http_verb to "GET" this is returned:
> Send_Subscription <- call_graph_url(Tok, Endpoint, body = Subscription_Properties, encode = "json",
+ content_type = "application/json",
+ http_verb = "GET",
+ http_status_handler = "message",

+ auto_refresh = TRUE
+ )
OK (HTTP 200). Failed to complete operation. Message:

What am I missing?
Thanks in advance for your help!
The goal was i aiming to is to change identifier from id of entity to JWT token that user has attached at specific path.
#ApiResource(
itemOperations = {
"get" ={
"security" = "is_granted('VIEW',object)",
"normalization_context" = {"groups" = {"read"}}
},
"put" = {
"security" = "is_granted('WRITE',object)",
"normalization_context" = {"groups" = {"get"}},
"denormalization_context" = {"groups" = {"put"}}
},
"api_users_cart_subresource" = {
"method" = "GET",
"path" = "/users/{id}/carts",
"security" = "is_granted('VIEW',object)",
"normalization_context" = {"groups" = {"user:cart"}}
}
},
collectionOperations = {
"post" = {
"denormalization_context" = {"groups" = {"post"}},
"normalization_context" = {"groups" = {"get"}}
},
"get" = {
"access_control" = "is_granted('ROLE_ADMIN')",
"normalization_context" = {"groups" = {"admin:read"}}
}
}
)
is it possible to change the path to /users/carts and return normalized data that belong to the user base from their token?
ps. sorry for my grammar
I have a map variable with many values (NACL rules). I am trying to add rules accordingly
variable "rules" {
default = {
a = "200,false,tcp,allow,0.0.0.0/0,23,23"
b = "100,true,tcp,allow,0.0.0.0/0,1024,65535"
}
}
resource "aws_network_acl_rule" "bar" {
network_acl_id = "<id>"
rule_number = "${split(",",element(values(var.rules),count.index))[0]}"
egress = "${split(",",element(values(var.rules),count.index))[1]}"
protocol = "${split(",",element(values(var.rules),count.index))[2]}"
rule_action = "${split(",",element(values(var.rules),count.index))[3]}"
cidr_block = "${split(",",element(values(var.rules),count.index))[4]}"
from_port = "${split(",",element(values(var.rules),count.index))[5]}"
to_port = "${split(",",element(values(var.rules),count.index))[6]}"
count = "${length(values(var.rules))}"
}
Error:
expected "}" but found "["
Since maps with lists as values aren't supported, I am trying to split the values and iterate
Another option, easier to read, is with lookup():
variable "rules" {
default = [
{
rule_number = 200
egress = false
protocol = "tcp"
rule_action = "allow"
cidr_block = "0.0.0.0/0"
from_port= 23
to_port = 23
},
{
rule_number = 100
egress = true
procotol = "tcp"
rule_action = "allow"
cidr_block = "0.0.0.0/0"
from_port = 1024
to_port = 65535
},
]
}
resource "aws_network_acl_rule" "bar" {
count = "${length(var.rules)}"
network_acl_id = "<id>"
rule_number = "${lookup(var.rules[count.index], "rule_number")}"
egress = "${lookup(var.rules[count.index], "egress")}"
protocol = "${lookup(var.rules[count.index], "protocol")}"
rule_action = "${lookup(var.rules[count.index], "rule_action")}"
cidr_block = "${lookup(var.rules[count.index], "cidr_block")}"
from_port = "${lookup(var.rules[count.index], "from_port")}"
to_port = "${lookup(var.rules[count.index], "to_port")}"
}
Here is a simpler way to deal with the map rules
variable "rules" {
default = {
"0" = "200,false,tcp,allow,0.0.0.0/0,23,23"
"1" = "100,true,tcp,allow,0.0.0.0/0,1024,65535"
}
}
resource "aws_vpc" "main" {
cidr_block = "10.0.0.0/16"
}
resource "aws_network_acl" "bar" {
vpc_id = "${aws_vpc.main.id}"
}
resource "aws_network_acl_rule" "bar" {
count = "${length(var.rules)}"
network_acl_id = "${aws_network_acl.bar.id}"
rule_number = "${element(split(",",var.rules[count.index]),0)}"
egress = "${element(split(",",var.rules[count.index]),1)}"
protocol = "${element(split(",",var.rules[count.index]),2)}"
rule_action = "${element(split(",",var.rules[count.index]),3)}"
cidr_block = "${element(split(",",var.rules[count.index]),4)}"
from_port = "${element(split(",",var.rules[count.index]),5)}"
to_port = "${element(split(",",var.rules[count.index]),6)}"
}
If you insist to use old map, key is "a,b,...", you need to adjust resource to
variable "rules" {
default = {
"a" = "200,false,tcp,allow,0.0.0.0/0,23,23"
"b" = "100,true,tcp,allow,0.0.0.0/0,1024,65535"
}
}
resource "aws_network_acl_rule" "bar" {
count = "${length(var.rules)}"
network_acl_id = "${aws_network_acl.bar.id}"
rule_number = "${element(split(",",element(values(var.rules),count.index)),0)}"
egress = "${element(split(",",element(values(var.rules),count.index)),1)}"
protocol = "${element(split(",",element(values(var.rules),count.index)),2)}"
rule_action = "${element(split(",",element(values(var.rules),count.index)),3)}"
cidr_block = "${element(split(",",element(values(var.rules),count.index)),4)}"
from_port = "${element(split(",",element(values(var.rules),count.index)),5)}"
to_port = "${element(split(",",element(values(var.rules),count.index)),6)}"
}
I am trying to send different contents to different recipients, but all recipients get all contents. Any help?
library(mailR)
msg<- data.frame(recipients=c("first#mail.com","second#mail.com","third#mail.com"),
messages=c("firstmsg","secondmsg","thirdmsg"))
for ( i in msg$recipients)
{
for (j in msg$messages) {
send.mail(from="myemail#mail.com",
to= i,
body = j,
subject = "subject",
encoding = "utf-8",
smtp= list(host.name = "smtp.gmail.com", port = 465,
user.name = "myemail#mail.com", passwd = "mypassword", ssl = TRUE),
authenticate = TRUE, send = TRUE, attach.files=NULL, debug = FALSE)
}
}
You are using a double loop which will go through each value of j for each value of i in your loop. One approach would be to use list indexing:
msg<-data.frame(recipients=c("first#mail.com","second#mail.com",
"third#mail.com"),messages=c("firstmsg","secondmsg","thirdmsg"))
for i in 1:nrow(msg)
{
send.mail(from="myemail#mail.com",
to= msg$recipients[i],
body = msg$message[i],
subject = "subject",
encoding = "utf-8",
smtp= list(host.name = "smtp.gmail.com", port = 465,
user.name = "myemail#mail.com", passwd = "mypassword", ssl = TRUE),
authenticate = TRUE, send = TRUE, attach.files=NULL, debug = FALSE)
}
