HttpURLConnection 只返回几个字节

Question

我有：

InputStream input = null;
HttpURLConnection connection = null;
URL url = new URL("...");

connection = (HttpURLConnection) url.openConnection();
String zam = "...";
connection.setRequestProperty("Cookie",zam);
connection.connect();

int fileLength = connection.getContentLength();
input = connection.getInputStream();
byte data[] = new byte[400];
int count;
count = input.read(data);
connection.disconnect();
String str1 = new String(data);

str1，响应总是只有：

!DOCTYPE HTML 公共“-/

而已。 但是当我关闭 cookie 时：

connection.setRequestProperty("Cookie",zam);

一切都好;

感谢 ind adv 的回复。 阿迪。

我想问题在于您没有从流中读取所有数据。 尝试使用这样的方法。

public static String streamToString(final InputStream is, final int bufferSize) throws Exception {
    final char[] buffer = new char[bufferSize];
    final StringBuilder out = new StringBuilder();
    try (Reader in = new InputStreamReader(is, "UTF-8")) {
        int rsz = 0;
        while ((rsz = in.read(buffer, 0, buffer.length)) > 0) {
            out.append(buffer, 0, rsz);
        }
    }
    return out.toString();
}
