Question

我尝试使用tryCatch和Sys.sleep来自动执行以下块，因此我不需要每15分钟继续返回并重新运行代码。< / p>

Twitter允许每15分钟下载一定数量的推文。在您达到最大值后，会出现错误消息。收到错误消息15分钟后，您可以下载的推文数量会重置。

列表（x）是我需要下载推文的几百个句柄。

# get initial list of Twitter Handles from df
x <- as.vector(df$Handle)

# get list of existing files from folder
f <- list.files("C:/workDump/")

# subset list of files if necessary
xSubset <- x[length(f):(length(x))]

# download the twitter timeline data for list elements which do not exist
for (i in xSubset){
  timeline <- userTimeline(i,n = 3200)
  timeline <- twListToDF(timeline)
  save(timeline, file=paste("workDump/", i, ".Rda"))
}

我已经使用了tryCatch和Sys.sleep的各种规格，此时我只是在混淆自己。

由于我无法使用您的代码，我只能猜测：

import socket
import sys
import time
import thread

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 15000)
sock.bind(server_address)
sock.listen(1)
connection, client_address = sock.accept()
Servername = raw_input('Starting the chat(enter "QUIT" to discontinue), Please enter your name: ')

def Server_outgoing():
    while True:
        outgoing_message_server = raw_input()
        if (outgoing_message_server == 'Quit' or outgoing_message_server == 'quit' or outgoing_message_server == 'QUIT'):
            print "Server has decided to abort the chat - Bye bye"
            break
        print "######################################################################"
        print >>sys.stderr, '"%s" : Printing outgoing message from Server "%s"' % (Servername, outgoing_message_server)
        print "######################################################################"
        connection.sendall(outgoing_message_server)     
try:
    thread.start_new_thread(Server_outgoing, ())
finally:
    connection.close()

超时15 * 60秒。

在遇到错误时使用带有Sys.sleep的tryCatch
