403在Python中请求图像URL时-在本地工作，但不适用于PythonAnywhere

如何解决403在Python中请求图像URL时-在本地工作，但不适用于PythonAnywhere

我正在尝试使用Python编写一个Twitter机器人，该机器人只是按时间表发送图像推特，并从一组URL中选择一个随机的机器人。我将图像托管在imgbb.com上，并使用tweepy进行鸣叫。

我的代码在本地计算机上的终端上运行时有效，但是现在我试图通过在Python Anywhere上运行它来进行部署。尝试获取图片时，我收到403请求。

获取图像的方法：

def tweet_image(url,message):
    filename = 'temp.jpg'
    request = requests.get(url,stream=True)
    if request.status_code == 200:
        with open(filename,'wb') as image:
            for chunk in request:
                image.write(chunk)

        api.update_with_media(filename,status=message)
        os.remove(filename)
    else:
        print("Unable to download image")

返回错误：

File "/home/user/.virtualenvs/my-virtualenv/lib/python3.6/site-packages/urllib3/connectionpool.py",line 727,in urlopen
    method,url,error=e,_pool=self,_stacktrace=sys.exc_info()[2]
  File "/home/user/.virtualenvs/my-virtualenv/lib/python3.6/site-packages/urllib3/util/retry.py",line 439,in increment
    raise MaxRetryError(_pool,error or ResponseError(cause))
urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='i.ibb.co',port=443): Max retries exceeded with url: /4gJLdfw/images-12.jpg (Caused by ProxyError('Cannot connect to proxy.',OSError('Tunnel connect
ion failed: 403 Forbidden',)))

我是否需要设置某种用户代理或请求标头才能使GET成功？我是python的新手。

解决方法

您可能在PythonAnywhere上拥有一个免费帐户，因此对外界的访问受到限制。您可以检查列入白名单的域here。我看到 function OnLoad() { let logFile = Path.join(__dirname,'logs',platformDirs[process.platform],'my.log'); let logElem = document.querySelector('.log'); processLineByLine(logFile,logElem); } // // helpers // async function processLineByLine(txtFile,outElement) { const fileStream = fs.createReadStream(txtFile); const rl = readline.createInterface({ input: fileStream,crlfDelay: Infinity }); // Note: we use the crlfDelay option to recognize all instances of CR LF // ('\r\n') in input.txt as a single line break. for await (const line of rl) { // Each line in input.txt will be successively available here as `line`. console.log(`Line from file: ${line}`); outElement.innerHTML += line + '<br>'; } } 重定向到具有列入白名单的api的inline bool OpenLogFile(FILE** ppLogFile) { TCHAR logPath[MAX_PATH]; DWORD length = GetModuleFileName(NULL,logPath,MAX_PATH); bool isPathValid = false; #if (NTDDI_VERSION >= NTDDI_WIN8) PathCchRemoveFileSpec(logPath,MAX_PATH); HRESULT resPath = PathCchCombine(logPath,MAX_PATH,TEXT("my.log")); isPathValid = (resPath == S_OK); #else PathRemoveFileSpec(logPath); LPWSTR resPath = PathCombine(logPath,TEXT("my.log")); isPathValid = (resPath != NULL) #endif if (!isPathValid) return false; errno_t res = _wfopen_s(ppLogFile,L"a"); if (res != 0) { wprintf(TEXT("Error: Failed to open log file: %s"),GetOSErrStr().c_str()); } return res == 0; } ，所以也许您应该尝试使用该域。
