while(bo!=10){
x = tryCatch(getURLContent(Site, verbose = F, curl = handle),
error = function(e) {
cat("ERROR1: ", e$message, "\n")
Sys.sleep(1)
print("reconntecting...")
bo <- bo+1
print(bo)
})
print(bo)
if(bo==0) bo=10
}
I wanted to try reconnecting each second after the connection failed. But the new assignment of the bo value is not effective. How can i do that? Or if you know how to reconnect using RCurl options (I really didn't find a thing) it would be amazing.
Every help is appreciated
The problem is the b0
scope of the assignment. However, I find try
a little more friendly than tryCatch
. This should work:
while(bo!=10){
x = try(getURLContent(Site, verbose = F, curl = handle),silent=TRUE)
if (class(x)=="try-error") {
cat("ERROR1: ", x, "\n")
Sys.sleep(1)
print("reconnecting...")
bo <- bo+1
print(bo)
} else {
break
}
}
The above attempts 10 times to connect to the site. If any of this time succeeds, it exits.
