在Python中，当出现`http.client.RemoteDisconnected: Remote end closed connection without response`错误时，可采用以下解决方法： - **设置User-Agent**：大部分网站会对用户请求里的 User-Agent 进行检测，若未在请求头中设置 User-Agent，就可能抛出异常。可在请求头`headers`中添加 User-Agent。 ```python import urllib.request # 要访问的地址 headers = { "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36" } try: postdata1 = urllib.parse.urlencode(data1).encode("UTF8") req_data1 = urllib.request.Request(login_url1, data=postdata1, headers=headers) response1 = urllib.request.urlopen(req_data1).read().decode("utf-8", "ignore") print(response1) except requests.ConnectionError as e: print('Error:', e.args) ``` 使用`requests`库时，设置 User-Agent 如下： ```python import requests headers = { 'User-Agent': "Mozilla/5.0 (Windows; U; Windows NT 5.2) Gecko/2008070208 Firefox/3.0.1" } resp = requests.get(url, headers=headers) print(resp.text) ``` - **添加表单信息**：若在进行如有道翻译等操作时出现该错误，可能是未添加表单信息，可补充相关表单数据。示例如下： ```python form = { "i": "inout", "from": "AUTO", "to": "AUTO", "smartresult": "dict", "client": "fanyideskweb", "salt": "1530014068235", "sign": "0a13eff5c3c1891d1b4818163f96e120", "doctype": "json", "version": "2.1", "keyfrom": "fanyi.web", "action": "FY_BY_REALTIME", "typoResult": "false" } ``` - **检查远程访问情况**：如果是通过远程访问（如访问github加载权重和网络模型）出现该错误，可多次尝试，有时可能是网络不稳定等原因导致，示例代码如下： ```python import torch basemodel = torch.hub.load('rwightman/gen-efficientnet-pytorch', 'tf_efficientnet_b5_ap', pretrained=True) ```
