我有一个网络服务，它接收多部分文件(在c#中)，当我通过chrome扩展(高级休息扩展)发送一个大文件(15MB)时，文件上传正常，我可以看到正文响应:
<response xmlns="http://schemas.datacontract.org" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Descripcion>blabla</Descripcion>
<Resultado>-9999</Resultado>
<Servicio xmlns:a="http://schemas.datacontract.org" i:nil="true" />
</reponse>
但是当我使用 android 调用时，我得到带有 200 code OK 响应的 header ，但我不知道如何获得正文响应:
这是我的代码:
/****** Informacion exif *****/
DefaultHttpClient mHttpClient;
HttpParams params = new BasicHttpParams();
params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
mHttpClient = new DefaultHttpClient(params);
HttpPost httppost = new HttpPost("HTTPS://SERVICIO.SVC");
httppost.setHeader("Connection", "Keep-Alive");
httppost.setHeader("SOAPAction", "http://tempuri.org/Service1");
httppost.setHeader("identificadorGUID", Guid);
httppost.setHeader("numeroServicio", codigoServicio);
httppost.setHeader("coordenadaLatitud", latitud);
httppost.setHeader("coordenadaLongitud", longitud);
if (QUEES == 0) {
extension = "jpg";
}
if (QUEES == 1) {
extension = "mp4";
}
httppost.setHeader("cuando", cuando);
httppost.setHeader("tipoMultimedia", String.valueOf(tipoMultimedia));
httppost.setHeader("extension", extension);
MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
FileBody fileBody = new FileBody(fichero, "multipart/form-data");
multipartEntity.addPart("image", fileBody);
httppost.setEntity(multipartEntity);
try {
HttpResponse response = mHttpClient.execute(httppost);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
resEntity.consumeContent();
}
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
httppost.getAllHeaders();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
Log.i("Respuesta web service", sResponse);
}
catch (ClientProtocolException e1) {
e1.printStackTrace();
}
catch (IOException e1) {
e1.printStackTrace();
}
崩溃:java.io.IOException:尝试从关闭的流中读取。
我怎样才能得到响应来解析它？ 谢谢
最佳答案
看来您不应该调用 consumeContent()直到读取信息(假设它关闭了流)。如果您使用的是 4.1 或更高版本，则此方法已被弃用，您应该使用 EntityUtils.consume(HttpEntity)
来自其 javadoc:
This method is called to indicate that the content of this entity is no longer required. All entity implementations are expected to release all allocated resources as a result of this method invocation. Content streaming entities are also expected to dispose of the remaining content, if any. Wrapping entities should delegate this call to the wrapped entity.
