httpresponse获取返回body

当你使用HTTP客户端（如Java的HttpURLConnection、HttpClient，Python的requests库等）发送请求并获取响应时，通常会得到一个HttpResponse对象。这个对象包含有关响应的各种信息，包括状态码、头信息以及响应体。在许多编程语言中，响应体通常存储在一个流（stream）或者字符串中，你可以通过以下步骤获取：

1. 对于Java的HttpURLConnection:

InputStream inputStream = httpResponse.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder responseBody = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
    responseBody.append(line);
}
reader.close();

2. Python的requests库:

response = requests.get('http://example.com')
response_body = response.text

3. JavaScript (fetch API):

fetch('http://example.com')
.then(response => response.text())
.then(responseBody => console.log(responseBody))
.catch(error => console.error(error));
