在 3g Android 上 httpget 后响应不完整

在我的 Android 应用程序中，我尝试使用 httpclient 和 httpget 获取网站。它在模拟器和我的 HTC Desire HD 上运行良好。但是当我断开 wifi 并尝试在 3G 网络上获取网页时，响应有时不完整。我正在使用以下代码来获取网页：

public String htmlBody (String strURI)
{
String strBody = "";
HttpClient httpclient = new DefaultHttpClient();
//HttpProtocolParams.setUseExpectContinue(httpclient.getParams(), false);
try {
        HttpGet httpget = new HttpGet(strURI);
        HttpResponse response = httpclient.execute(httpget, localContext);

        HttpEntity entity = response.getEntity();

        strBody = Functions.convertStreamToString(entity.getContent());
    }
} finally {
    httpclient.getConnectionManager().shutdown();
}

return strBody;
}

有没有办法确保响应完整？或者当响应不完整时恢复httpget？

in my Android application i am trying to get a website using the httpclient and the httpget.
it is working fine on the emulator and on my HTC Desire HD.
but when i disconnect from wifi and try to get te webpage on the 3G network the response is sometimes incomplete.
i am using the following code to get the webpage:

public String htmlBody (String strURI)
{
String strBody = "";
HttpClient httpclient = new DefaultHttpClient();
//HttpProtocolParams.setUseExpectContinue(httpclient.getParams(), false);
try {
        HttpGet httpget = new HttpGet(strURI);
        HttpResponse response = httpclient.execute(httpget, localContext);

        HttpEntity entity = response.getEntity();

        strBody = Functions.convertStreamToString(entity.getContent());
    }
} finally {
    httpclient.getConnectionManager().shutdown();
}

return strBody;
}

is there a way to make sure that the response is complete? or resume the httpget when the response is incomplete?

我最近也遇到了和你同样的问题。经过几次实验，我想我找到了答案：
Android 不会在 3G 网络中通过单个 InputStream#read() 调用读取完整的响应。
以下代码可能有效：

InputStream in = entity.getContent();
int length = 0;
while (true) {
    int ret = in.read(buffer, length, buffer.length - length);
    if (ret == -1) break;
    length += ret;
}

I've encountered the same problem with you recently. After a few experiments, I guess I found the answer:
Android won't read complete response with a single InputStream#read() call in 3G network.
The following code may work:

InputStream in = entity.getContent();
int length = 0;
while (true) {
    int ret = in.read(buffer, length, buffer.length - length);
    if (ret == -1) break;
    length += ret;
}
