--------------------------------------
Hello my friend,now I can show a test case:
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.InputStream;
import java.nio.charset.Charset;
import java.util.ArrayList;
import java.util.List;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.params.HttpParams;
import org.apache.http.params.HttpProtocolParams;
public class TestMime {
public static void sendFile(){
MultipartEntityBuilder mult = MultipartEntityBuilder.create();
//I use a wrong token cause it's just a test.If I want to get a
right token,I must login the server,
//it's hard to do it here.
mult.addTextBody("k", "a_test_token");
mult.addBinaryBody("attfile", new File("C://测试.txt"));
//this is just a test method,if I set the carset,the server
will return:{"r":10500,"d":"access_token not found"}
//if I don't set the charset,the server will
return:{"r":10504,"d":"verify access_token failed"}
// mult.setCharset(Charset.forName("UTF-8"));
HttpClient httpclient = new DefaultHttpClient();
InputStream is = null;
HttpPost request = new
HttpPost("http://m0.mail.sina.com.cn/api/upload.php";);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setUserAgent(httpclient.getParams(),
"SMail/1.0.3"); //设置代理
request.setParams(params);
String result = "";
try {
request.setEntity(mult.build());
HttpResponse httpResponse = httpclient.execute(request);
if (httpResponse.getStatusLine().getStatusCode() ==
HttpStatus.SC_OK) {
is = httpResponse.getEntity().getContent();
result = inStream2String(is);
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(result);
}
private static String inStream2String(InputStream is) throws Exception {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buf = new byte[1024];
int len = -1;
while ((len = is.read(buf)) != -1) {
baos.write(buf, 0, len);
}
return new String(baos.toByteArray(), "utf-8");
}
public static void main(String[] args){
sendFile();
}
}
these are the jars I used:
commons-codec-1.6.jar
commons-logging-1.1.3.jar
httpclient-4.3.6.jar
httpcore-4.3.3.jar
httpmime-4.3.6.jar
If I don't set the charset,the server will receive the token and check it;but
if I set the charset the server will not receive the token.
> MultipartEntity doesn't work when I set Charset for it

> Key: HTTPCLIENT-1594
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1594
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpMime
> Affects Versions: 4.2.6
> Environment: Client info: Android,Sumsung note3
> Server info: php server
> Reporter: MaiZhang
> Labels: features
>
> I need upload files to my server,but the file name maybe Chinese.So I want to
> set charset to MultipartEntity,cuz its default charset is US-ASCII,the file
> name be sended to server looks like "?????.txt" eg. .But, when I set UTF-8 to
> it,the server can't get any data.
> MultipartEntity mult = new MultipartEntity();
> mult.addPart("k", new
> StringBody(getAccessToken().getAccessToken()));
> mult.addPart("attfile", new FileBody(new
> File(entity.getFilePath())));
> This code works well,but::::::
> MultipartEntity mult = new
> MultipartEntity(null,null,Charset.forName("UTF-8"));
> mult.addPart("k", new
> StringBody(getAccessToken().getAccessToken()));
> mult.addPart("attfile", new FileBody(new
> File(entity.getFilePath())));
> can't post data to server,it's too strange!!!
> AND!!!!!!!
> if I use
> MultipartEntity mult = new MultipartEntity();
> this way and set breakpoint at the second line,and change the value of
> multipart-charset-canonicalName to "UTF-8",the server will get the right file
> name,I think if I set charset to a MultipartEntity object,it will not work.
> And, I tested httpmime4.3.x,by MultipartEntityBuilder,it doesn't work too.
