Android从 HttpResponse (或者InputStream) 获取字符串内容

这段Android代码从InputStream读取内容到字符串。可以用于任何类型的InputStream，包括从HttpClient获取的HttpResponse

使用 inputStreamToString(response.getEntity().getContent())从HttpResponse 读取

// Fast Implementation
private StringBuilder inputStreamToString(InputStream is) {
    String line = "";
    StringBuilder total = new StringBuilder();
    
    // Wrap a BufferedReader around the InputStream
    BufferedReader rd = new BufferedReader(new InputStreamReader(is));

    // Read response until the end
    while ((line = rd.readLine()) != null) { 
        total.append(line); 
    }
    
    // Return full string
    return total;
}

// Slow Implementation from 75271.com
private String inputStreamToString(InputStream is) {
    String s = "";
    String line = "";
    
    // Wrap a BufferedReader around the InputStream
    BufferedReader rd = new BufferedReader(new InputStreamReader(is));
    
    // Read response until the end
    while ((line = rd.readLine()) != null) { s += line; }
    
    // Return full string
    return s;
}
