post メソッドを使用してサーバーに接続し、結果を取得するアプリケーションを構築しています。サーバー応答の特定の部分を取得し、それをさまざまなタイプのプリミティブ (から 、 など) に変換する必要Stringがshortありますint。byte
したがって、基本的には、enumこの値を持つ要素があるかどうかを確認するよりも、応答コードの一部を取得してそれを short に変換する必要があります。しかし、問題は、応答が値001を返し、それを short に変換して自分ののgetByValue(int)メソッドではenum、001 の要素がないと言っています。short取得した値を出力すると、 1.
これが私が使用しているコードのサンプルです:
httppost.setEntity(new UrlEncodedFormEntity(postParameters));
HttpResponse response = httpclient.execute(httppost);
Log.v("Response ","Status line : "+ response.getStatusLine().toString());
String responseBody = EntityUtils.toString(response.getEntity()); //response
Log.v("Response ","Response : "+ responseBody);
int objectIdentificator = Integer.parseInt(responseBody.substring(0,32));
Log.v("Response ","Object Identificator (LONGINT) : "+ responseBody.substring(0,32));
Log.v("Response ","Object Identificator (LONGINT) : "+ objectIdentificator);
String type = responseBody.substring(32,35);
Log.v("Response ","TYPE (UNSIGNED BYTE) : "+ type);
short pType = Short.parseShort(type); // short
Log.v("Response ","TYPE (UNSIGNED BYTE) : "+ pType);
String operation = responseBody.substring(35,38); //
short operationType = Short.parseShort(operation);
Log.v("Response ","OPERATION (UNSIGNED BYTE) : "+ operation);
Log.v("Response ","OPERATION (UNSIGNED BYTE) : "+ operationType);
String objectId = responseBody.substring(38, 70);
Log.v("Response ","UID (CHAR, length 32) : "+ objectId);
int id = Integer.parseInt(responseBody.substring(70, 102));
Log.v("Response ","ID (LONGINT) : "+ responseBody.substring(70, 102));
Log.v("Response ","ID (LONGINT) : "+ id);
String size = responseBody.substring(102,134);
Log.v("Response ","Data Size (LONGINT) : "+ size);
String hash = responseBody.substring(134,166);
Log.v("Response ","Data Hash (CHAR, length 32 : "+ hash);
String dType = responseBody.substring(166,169);
Log.v("Response ","Data Type (UNSIGNED BYTE) : "+ dType);
short dataType = Short.parseShort(dType);
Log.v("Response ","Data Type (UNSIGNED BYTE) : "+ dataType);
String data = responseBody.substring(169, responseBody.length());
Log.v("Response ","Data (CHAR, any length, in BASE64) : "+ data);
byte[] first = Base64.decode(data);
String string = new String(first, "UTF-8");
Log.v("Response ","BASE 64 : "+ string);
RPCPacket packet = new RPCPacket( objectIdentificator,
RPCPacketType.getPacketTypeByValue(pType),
RPCOperationType.getByValue(Integer.parseInt(operation)),
objectId,
id,
Integer.parseInt(size),
hash,
RPCPacketDataType.getByValue(dataType),
first
);
Log.v("PacketType", "RPCPacketType : "+packet.packetTypeToStr(RPCPacketType.getPacketTypeByValue(pType)));
そして packetTypeToStr コード:
public String packetTypeToStr(RPCPacketType type){
String str=null;
switch(type){
case ST_OBJECT_TYPE_INFO_START:
str = "ST_OBJECT_TYPE_INFO_START";
break;
case ST_OBJECT_TYPE_INFO_ERROR:
str = "ST_OBJECT_TYPE_INFO_ERROR";
break;
case ST_OBJECT_TYPE_COLLECTION:
str = "ST_OBJECT_TYPE_COLLECTION";
break;
case ST_OBJECT_TYPE_CATEGORY:
str = "ST_OBJECT_TYPE_CATEGORY";
break;
case ST_OBJECT_TYPE_CARD:
str = "ST_OBJECT_TYPE_CARD";
break;
case ST_OBJECT_TYPE_MESSAGE:
str = "ST_OBJECT_TYPE_MESSAGE";
break;
case ST_OBJECT_TYPE_GENRE:
str = "ST_OBJECT_TYPE_GENRE";
break;
case ST_OBJECT_TYPE_TAG:
str = "ST_OBJECT_TYPE_TAG";
break;
case ST_OBJECT_TYPE_USER:
str = "ST_OBJECT_TYPE_USER";
break;
case ST_OBJECT_TYPE_MEDIA_COLLECTION:
str = "ST_OBJECT_TYPE_MEDIA_COLLECTION";
break;
case ST_OBJECT_TYPE_MEDIA_CATEGORY:
str = "ST_OBJECT_TYPE_MEDIA_CATEGORY";
break;
case ST_OBJECT_TYPE_MEDIA_CARD:
str = "ST_OBJECT_TYPE_MEDIA_CARD";
break;
case ST_OBJECT_TYPE_MEDIA_TAG:
str = "ST_OBJECT_TYPE_MEDIA_TAG";
break;
case ST_OBJECT_TYPE_INFO_END:
str = "ST_OBJECT_TYPE_INFO_END";
break;
case ST_OBJECT_TYPE_CARDSTATS_CATEGORY:
str = "ST_OBJECT_TYPE_CARDSTATS_CATEGORY";
break;
case ST_OBJECT_TYPE_CONTENT:
str = "ST_OBJECT_TYPE_CONTENT";
break;
case ST_OBJECT_TYPE_MEDIA_COLLECTION_BUTTON:
str = "ST_OBJECT_TYPE_MEDIA_COLLECTION_BUTTON";
break;
default:
str ="UNKNOWN "+type;
break;
}
return str;
}
