我要发

 <消息ID =qm5Dx-8
 为=ABC
 TYPE =聊天
 从=ABC
 MSGTYPE =2
 msgTimeStamp =1413971599039
 作品尺寸=18 MB
 fileHeight =300
 fileWidth =300
 缩略图=ABC
 mediaURL =
 serverMediaURL =XYZ
 isFromMe =1
 状态=1><身体GT;图片< /身体GT;<请求的xmlns =瓮:XMPP:收据/>< /消息>
 

的方式,我构建自定义消息是:

 公共类MyCustomMessage扩展消息{

    公共MyCustomMessage(){
        超();
    }

    公共MyCustomMessage(字符串,类型类型){
        超(于类型);
    }
    私人字符串MSGTYPE;
    私人字符串msgTimeStamp;
    私人字符串isFromMe;
    私人字符串状态;
    私人字符串mediaURL;
    私人字符串serverMediaURL;
    私人字符串的文件大小;
    私人字符串fileHeight;
    私人字符串fileWidth;
    私人字符串缩略图;

    @覆盖
    公共toxml用于字符串(){
        串XMLMessage = super.toXML();
        串XMLMessage1 = XMLMessage.substring(0,XMLMessage.indexOf(>中));
        串XMLMessage2 = XMLMessage.substring(XMLMessage.indexOf(>中));

        如果(this.msgType!= NULL){
            XMLMessage1 + =MSGTYPE = + this.msgType +;
        }
        如果(this.msgTimeStamp!= NULL){
            XMLMessage1 + =msgTimeStamp = + this.msgTimeStamp +;
        }
        如果(this.fileSize!= NULL){
            XMLMessage1 + =文件大小= + this.fileSize +;
        }
        如果(this.fileHeight!= NULL){
            XMLMessage1 + =fileHeight = + this.fileHeight +;
        }
        如果(this.fileWidth!= NULL){
            XMLMessage1 + =fileWidth = + this.fileWidth +;
        }
        如果(this.thumbnail!= NULL){
            XMLMessage1 + =缩略图= + this.thumbnail +;
        }
        如果(this.mediaURL!= NULL){
            XMLMessage1 + =mediaURL = + this.mediaURL +;
        }
        如果(this.serverMediaURL!= NULL){
            XMLMessage1 + =serverMediaURL = + this.serverMediaURL +;
        }
        如果(this.isFromMe!= NULL){
            XMLMessage1 + =isFromMe = + this.isFromMe +;
        }
        如果(this.status!= NULL){
            XMLMessage1 + =状态= + this.status +;
        }

        返回XMLMessage1 + XMLMessage2;
    }

//所有这些领域的二传手吸气剂..

}
 

然后,在SmackableImplement类添加所需的字段后,即时调用的 mXMPPConnection.sendPacket(customMessage);

但中号未接收到任何数据包。我的连接是调用此方法后是封闭的每次。我已经经历了很多教程走了,但无法找到任何解决办法...告诉我,其中M是错误的。

解决方案

啪肯定有一个更好的方式使用XML比这种方法与修改字符串重新presentation工作。这将破坏严重时,任何包含或任何需要被转义为属性的其他字符。

您要自定义的有效载荷添加到邮件作为一个单独的XML元素在消息中,而不是在消息的属性。您的XML应该是这样的:

 <消息ID =qm5Dx-8=ABC型=聊天,从=ABC>
    <身体GT;图片< /身体GT;
    <请求的xmlns =瓮:XMPP:收据/>
    <数据的xmlns =HTTP:// bstkaal /自定义/数据
      MSGTYPE =2
      msgTimeStamp =1413971599039
      作品尺寸=18 MB
      fileHeight =300
      fileWidth =300
      缩略图=ABC
      mediaURL =
      serverMediaURL =XYZ
      isFromMe =1
      状态=1/>
< /消息>
 

I want to send

<message id="qm5Dx-8"
 to="abc"
 type="chat" 
 from="abc"
 msgType="2"
 msgTimeStamp="1413971599039"
 fileSize="18 MB" 
 fileHeight="300"
 fileWidth="300"
 thumbnail="abc"
 mediaURL=""
 serverMediaURL="xyz"
 isFromMe="1"
 status="1"><body>Image</body><request xmlns='urn:xmpp:receipts'/></message>

The way i am constructing the custom message is :

public class MyCustomMessage  extends Message{

    public MyCustomMessage(){
        super();
    }

    public MyCustomMessage(String to, Type type){
        super(to, type);
    }
    private String msgType ;
    private String msgTimeStamp ;
    private String isFromMe ;
    private String status ;
    private String mediaURL ;
    private String serverMediaURL ;
    private String fileSize ;
    private String fileHeight ;
    private String fileWidth ;
    private String thumbnail ;

    @Override
    public String toXML() {
        String XMLMessage = super.toXML();
        String XMLMessage1 = XMLMessage.substring(0, XMLMessage.indexOf(">"));
        String XMLMessage2 = XMLMessage.substring(XMLMessage.indexOf(">"));

        if (this.msgType != null) {
            XMLMessage1 += " msgType="" + this.msgType + """;
        }
        if (this.msgTimeStamp != null) {
            XMLMessage1 += " msgTimeStamp="" + this.msgTimeStamp + """;
        }
        if (this.fileSize != null) {
            XMLMessage1 += " fileSize="" + this.fileSize + """;
        }
        if (this.fileHeight != null) {
            XMLMessage1 += " fileHeight="" + this.fileHeight + """;
        }
        if (this.fileWidth != null) {
            XMLMessage1 += " fileWidth="" + this.fileWidth + """;
        }
        if (this.thumbnail != null) {
            XMLMessage1 += " thumbnail="" + this.thumbnail + """;
        }
        if (this.mediaURL != null) {
            XMLMessage1 += " mediaURL="" + this.mediaURL + """;
        }
        if (this.serverMediaURL != null) {
            XMLMessage1 += " serverMediaURL="" + this.serverMediaURL + """;
        }
        if (this.isFromMe != null) {
            XMLMessage1 += " isFromMe="" + this.isFromMe + """;
        }
        if (this.status != null) {
            XMLMessage1 += " status="" + this.status + """;
        }

        return XMLMessage1 + XMLMessage2;
    }

// Setters Getters of all these fields..

}

Then after adding required fields in SmackableImplement class, i m calling mXMPPConnection.sendPacket(customMessage);

but m not receiving any packet. my connections is being closed everytime after calling this method. I have gone through many tutorials but couldnt find any solution...tell me where m mistaken.

解决方案

Smack surely has a better way to work with XML than this approach with modifying the string representation. This will break badly when anything contains a " or any of the other characters that need to be escaped as an attribute.

You have to add custom payloads to messages as a separate XML element within the message, not as attributes on the message. Your XML should look like:

 <message id="qm5Dx-8" to="abc" type="chat" from="abc">
    <body>Image</body>
    <request xmlns='urn:xmpp:receipts'/>
    <data xmlns='http://bstkaal/custom/data'
      msgType="2"
      msgTimeStamp="1413971599039"
      fileSize="18 MB" 
      fileHeight="300"
      fileWidth="300"
      thumbnail="abc"
      mediaURL=""
      serverMediaURL="xyz"
      isFromMe="1"
      status="1" />
</message>
