Question

我希望每次抛出502 HTTP错误或Floodwaiterror之类的异常时重新启动循环或继续，但我不知道或不知道该怎么做

代码：

//FUNCTION FROM LIBRARY
 // get GPS information
  bool getGPS(float *lat, float *lon, float *speed=0, float *alt=0, float *course=0, int *vsat=0, int *usat=0) {
    //String buffer = "";
    bool fix = false;

    sendAT(GF("+CGNSINF"));
    if (waitResponse(GF(GSM_NL "+CGNSINF:")) != 1) {
      return false;
    }

    stream.readStringUntil(','); // mode [GNSS off=0, GNSS on=1]
    if ( stream.readStringUntil(',').toInt() == 1 ) fix = true;
    stream.readStringUntil(','); //utctime yyyyMMddhhmmss.sss
    *lat =  stream.readStringUntil(',').toFloat(); //lat ±dd.dddddd
    *lon =  stream.readStringUntil(',').toFloat(); //lon ±ddd.dddddd
    if (alt != NULL) *alt =  stream.readStringUntil(',').toFloat(); //altitude metere
    if (speed != NULL) *speed = stream.readStringUntil(',').toFloat(); //speed Km/hour [0,999.99]
    if (course != NULL) *course = stream.readStringUntil(',').toFloat(); //course over ground degrees [0,360.00]
    stream.readStringUntil(',');//Fix mode [0,1,2]
    stream.readStringUntil(',');//Reserved1
    stream.readStringUntil(',');//HDOP [0,99.9]
    stream.readStringUntil(',');//PDOP [0,99.9]
    stream.readStringUntil(',');//VDOP [0,99.9]
    stream.readStringUntil(',');//Reserved2
    if (vsat != NULL) *vsat = stream.readStringUntil(',').toInt(); //viewed satelites
    if (usat != NULL) *usat = stream.readStringUntil(',').toInt(); //used satelites
    stream.readStringUntil(',');//GLONASS Sats used
    stream.readStringUntil(',');//Reserved3
    stream.readStringUntil(',');//C/N0 max (dBHz 0-55)
    stream.readStringUntil(',');//HPA (meters [0,9999.9])
    stream.readStringUntil(',');//VPA (meters [0,9999.9])
    stream.readStringUntil('\n');

    waitResponse();

    return fix;
}

//CALL FROM CODE
  gps_fixstatus = modem.getGPS(&gps_latitude, &gps_longitude, &gps_speed, &gps_altitude, &gps_course, &gps_view_satellites, &gps_used_satellites);
  if ( gps_fixstatus ) {
    gps_altitude=gps_altitude*3.2808; 
    sprintf(payload, "{\"lat\":%8f,\"long\":%8f,\"speed\":%2f,\"head\":%2f,\"alt\":%2f}", gps_latitude,gps_longitude, gps_speed, gps_course, gps_altitude); //JSON-ify
    SerialMon.println(payload); //JSON object
 }

在每个异常中关闭循环的异常输出

Serial.print(TinyGPSplus.location.lat())

我还尝试在每个异常（loop.close）中关闭循环

import time
from telethon import TelegramClient,errors
from telethon.tl.functions.photos import UploadProfilePhotoRequest
import os
import urllib.request
import urllib.error
import asyncio
from datetime import datetime
import datetime
api_id =  XXXXXX
api_hash = 'XXXXXXXXXXXXXXXX'

client = TelegramClient('Test_Session', api_id, api_hash)
client.start()

async def Change_Photo():
    try:
        while True:
            time.sleep(3)
            if os.path.exists("cat.jpg"):
                os.remove("cat.jpg")
            if os.path.exists("cat"):
                os.remove("cat")
            urllib.request.urlretrieve("https://cataas.com/cat", "cat")
            os.rename('cat', 'cat.jpg')

            await client(UploadProfilePhotoRequest(await client.upload_file(r"C:\Users\localhost\PycharmProjects\Scripts Python\Telethon\cat.jpg")))
            now = datetime.datetime.now()
            os.remove("cat.jpg")
            print("Changed Photo:", now.strftime("%Y-%m-%d %H:%M:%S"))
    except errors.FloodWaitError as e:
        print('Have to sleep', e.seconds, 'seconds')
        await asyncio.sleep(e.seconds)

    except urllib.error.HTTPError as e:
        if e.code == 502:
            print("HTTP error 502... Trying again")





loop = asyncio.get_event_loop()
loop.run_until_complete(Change_Photo())
loop.close()

但是其中一个可行：

几周前，我对学习python的编码非常陌生，以确保我做得不好，但我找不到什么

仅是为了完成和描述基本概念：代替

var timestampData1 = [1555486016,1555486017,1555486018...]; 
var timestampData2 = [1555486016,1555486017,1555486018...];

var data = [];
data[1] = [];
$.each(timestampData1,function(index,value) {
    data[1][value] = 1;
});
data[2] = [];
$.each(timestampData2,function(index,value) {
    data[2][value] = 1;
});
console.log(data);

使用

async def important_error_prone_function():
    try:
        while True:
            do_something()
    except Error1:
        correct_stuff_1()
    except Error2:
        correct_stuff_2()

然后，您的功能将继续运行，直到您要停止它为止。

感谢@ sparky05提供的解决方案，我并没有意识到有例外情况

from telethon import TelegramClient,errors
from telethon.tl.functions.photos import UploadProfilePhotoRequest
import os
import urllib.request
import urllib.error
import asyncio
from datetime import datetime
import datetime
api_id =  XXXXX
api_hash = 'XXXXXXXXXXXX'

client = TelegramClient('Change_Photo', api_id, api_hash)
client.start()

async def Change_Photo():
    while True:
        try:
            #time.sleep(0)
            if os.path.exists("cat.jpg"):
                os.remove("cat.jpg")
            if os.path.exists("cat"):
                os.remove("cat")
            urllib.request.urlretrieve("https://cataas.com/cat", "cat")
            os.rename('cat', 'cat.jpg')

            await client(UploadProfilePhotoRequest(await client.upload_file(r"C:\Users\localhost\PycharmProjects\Scripts Python\Telethon\cat.jpg")))
            now = datetime.datetime.now()
            os.remove("cat.jpg")
            print("Changed Photo:", now.strftime("%Y-%m-%d %H:%M:%S"))
        except errors.FloodWaitError as e:
            print('Have to sleep', e.seconds, 'seconds')
            await asyncio.sleep(e.seconds)

        except urllib.error.HTTPError as e:
            if e.code == 502:
                print("HTTP error 502... Trying again")
        # except errors.FloodWaitError as e:
        #     print('Have to sleep', e.seconds, 'seconds')
        #     await asyncio.sleep(e.seconds)
        #
        #  except urllib.error.HTTPError as e:
        #     if e.code == 502:
        #      print("HTTP error 502... Trying again")






loop = asyncio.get_event_loop()
loop.run_until_complete(Change_Photo())
loop.close()

异常重启asyncio循环？
