java - Content-Length 分隔消息正文的过早结束(预期为 :

Question

我正在尝试借助 apache httpclient 获取 HTTP 响应。我成功获取了 header ，但是当我尝试获取内容时它抛出异常。异常(exception)是:

 org.apache.http.ConnectionClosedException: Premature end of Content-Length delimited message body (expected: 203856; received: 1070
        at org.apache.http.impl.io.ContentLengthInputStream.read(ContentLengthInputStream.java:180)
        at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:283)
        at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:325)
        at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:177)
        at java.io.InputStreamReader.read(InputStreamReader.java:184)
        at java.io.BufferedReader.fill(BufferedReader.java:154)
        at java.io.BufferedReader.readLine(BufferedReader.java:317)
        at java.io.BufferedReader.readLine(BufferedReader.java:382)

我的代码是:

InputStream is = entity.getContent();
BufferedReader br = new BufferedReader( new InputStreamReader(is, "UTF-8"));
String line;
String str = "";
while ((line = br.readLine()) != null) {

    str = str + line + "\n";

}
log.debug(str);

任何帮助将不胜感激。谢谢

我可能会晚点回复它。但是我也遇到了同样的问题。我得到了解决方案。在我的例子中，我在使用 HttpEntity 之前关闭了客户端。关闭客户端后，我试图下载文件。下面的代码与我所做的类似:

HttpEntity httpEntity = null;
try (final CloseableHttpClient client = createHttpClient()) {
     httpEntity = getEntity(client);
}

return downloadFile(httpEntity, targetDirectory, fileName);

在关闭客户端之前调整我的代码以下载文件后，它现在对我有用。下面的代码与我现在所做的类似:

try (final CloseableHttpClient client = createHttpClient()) {
     HttpEntity httpEntity = getEntity(client);
     return downloadFile(httpEntity, targetDirectory, fileName);
}
