任何人都可以帮助使用Phonegap在后台发送电子邮件

我找不到支持表格。任何人都可以在这个问题上帮助我。提前谢谢......

Answer 1

您可以使用插件Email Composer，也可以使用mailto标记调用智能手机的本机mailinbox：

  <a href="mailto:?subject=subject of the email&body=whatever body body" target="_blank">send email</a>

有关mailto参数的详细信息，请检查此question

Answer 2

步骤1：在项目类路径中添加cordova-2.1.0.jar

步骤2：在assets / www / js文件夹中添加cordova-2.1.0.js。

步骤3：创建一个名为EmailComoposer.java的新Java类

package com.dinesh.pb;
import org.apache.cordova.api.Plugin;
import org.apache.cordova.api.PluginResult;
import org.apache.cordova.api.PluginResult.Status;
import org.json.JSONArray;
import org.json.JSONException;
import android.annotation.SuppressLint;
import android.content.Intent;
import android.text.Html;
import com.dinesh.pb.utility.Mail;

@SuppressLint("ParserError")
public class EmailComposer extends Plugin {
public final String ACTION_SEND_EMAIL = "sendEmail";

 @Override
 public PluginResult execute(String action, JSONArray arg1, String callbackId) {
 PluginResult result = new PluginResult(Status.INVALID_ACTION);
 if (action.equals(ACTION_SEND_EMAIL)) {
 try {
 String message = arg1.getString(0);
 this.sendEmailViaGmail(message);
 result = new PluginResult(Status.OK);

 }
 catch (JSONException ex) {
 result = new PluginResult(Status.JSON_EXCEPTION, ex.getMessage());
 } catch (Exception e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 } 
 }
 return result;
 }

 private void sendEmailViaGmail(String body) throws Exception{
 Mail m = new Mail("From_email_address@gmail.com", "your password");
 String[] toArr = {"TO_EMAIL_ADDRESS@gmail.com"};
 m.set_to(toArr);
 m.set_from("FROM_EMAIL_ADDRESS@gmail.com");
 m.set_body(body);
 m.set_subject("TEST SUBJECT");
 boolean sendFlag = m.send();

 }

}

步骤4.将此Mail.java复制到您选择的包中。我的包名是com.dinesh.pb.utility。

package com.dinesh.pb.utility;
import java.util.Date;
import java.util.Properties;
import javax.activation.CommandMap;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.activation.MailcapCommandMap;
import javax.mail.BodyPart;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class Mail extends javax.mail.Authenticator { 
 private String _user; 
 private String _pass; 

 private String[] _to; 
 private String _from; 

 private String _port; 
 private String _sport; 

 private String _host; 

 private String _subject; 
 private String _body; 

 private boolean _auth; 

 private boolean _debuggable; 

 private Multipart _multipart; 

 public Mail() { 
 _host = "smtp.gmail.com"; // default smtp server 
 _port = "465"; // default smtp port 
 _sport = "465"; // default socketfactory port 

 _user = ""; // username 
 _pass = ""; // password 
 _from = ""; // email sent from 
 _subject = ""; // email subject 
 _body = ""; // email body 

 _debuggable = false; // debug mode on or off - default off 
 _auth = true; // smtp authentication - default on 

 _multipart = new MimeMultipart(); 

 // There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added. 
 MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap(); 
 mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html"); 
 mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml"); 
 mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain"); 
 mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed"); 
 mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822"); 
 CommandMap.setDefaultCommandMap(mc); 
 } 

 public Mail(String user, String pass) { 
 this(); 

 _user = user; 
 _pass = pass; 
 } 

 public boolean send() throws Exception { 
 Properties props = _setProperties(); 

 if(!_user.equals("") && !_pass.equals("") && _to.length > 0 && !_from.equals("") && !_subject.equals("") && !_body.equals("")) { 
 Session session = Session.getInstance(props, this); 

 MimeMessage msg = new MimeMessage(session); 

 msg.setFrom(new InternetAddress(_from)); 

 InternetAddress[] addressTo = new InternetAddress[_to.length]; 
 for (int i = 0; i < _to.length; i++) { 
 addressTo[i] = new InternetAddress(_to[i]); 
 } 
 msg.setRecipients(MimeMessage.RecipientType.TO, addressTo); 

 msg.setSubject(_subject); 
 msg.setSentDate(new Date()); 

 // setup message body 
 BodyPart messageBodyPart = new MimeBodyPart(); 
 messageBodyPart.setText(_body); 
 _multipart.addBodyPart(messageBodyPart); 

 // Put parts in message 
 msg.setContent(_multipart); 

 // send email 
 Transport.send(msg); 

 return true; 
 } else { 
 return false; 
 } 
 } 

 public void addAttachment(String filename) throws Exception { 
 BodyPart messageBodyPart = new MimeBodyPart(); 
 DataSource source = new FileDataSource(filename); 
 messageBodyPart.setDataHandler(new DataHandler(source)); 
 messageBodyPart.setFileName(filename); 

 _multipart.addBodyPart(messageBodyPart); 
 } 

 public String[] get_to() {
 return _to;
 }
public void set_to(String[] _to) {
 this._to = _to;
 }
public String get_from() {
 return _from;
 }
public void set_from(String _from) {
 this._from = _from;
 }
public String get_body() {
 return _body;
 }
public void set_body(String _body) {
 this._body = _body;
 }
@Override 
 public PasswordAuthentication getPasswordAuthentication() { 
 return new PasswordAuthentication(_user, _pass); 
 } 

 private Properties _setProperties() { 
 Properties props = new Properties(); 

 props.put("mail.smtp.host", _host); 

 if(_debuggable) { 
 props.put("mail.debug", "true"); 
 } 

 if(_auth) { 
 props.put("mail.smtp.auth", "true"); 
 } 

 props.put("mail.smtp.port", _port); 
 props.put("mail.smtp.socketFactory.port", _sport); 
 props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
 props.put("mail.smtp.socketFactory.fallback", "false"); 

 return props; 
 }
public String get_subject() {
 return _subject;
 }
public void set_subject(String _subject) {
 this._subject = _subject;
 }

 // more of the getters and setters ….. 
 }

步骤5：更新config.xml并添加有关新插件类EmailComposer.java的详细信息。我看起来像这样 - 。请使用您的包路径更新包名称value =“com.dinesh.pb.EmailComposer”。

<?xml version="1.0" encoding="utf-8"?> 
<cordova>
    <access origin="http://127.0.0.1*"/> <!-- allow local pages --> 
    <access origin=".*"/> 
    <log level="DEBUG"/>
    <preference name="useBrowserHistory" value="false" />
    <preference name="exit-on-suspend" value="false" />
<plugins>
    <plugin name="App" value="org.apache.cordova.App"/>
    <plugin name="Geolocation" value="org.apache.cordova.GeoBroker"/>
    <plugin name="Device" value="org.apache.cordova.Device"/>
    <plugin name="Accelerometer" value="org.apache.cordova.AccelListener"/>
    <plugin name="Compass" value="org.apache.cordova.CompassListener"/>
    <plugin name="Media" value="org.apache.cordova.AudioHandler"/>
    <plugin name="Camera" value="org.apache.cordova.CameraLauncher"/>
    <plugin name="Contacts" value="org.apache.cordova.ContactManager"/>
    <plugin name="File" value="org.apache.cordova.FileUtils"/>
    <plugin name="NetworkStatus" value="org.apache.cordova.NetworkManager"/>
    <plugin name="Notification" value="org.apache.cordova.Notification"/>
    <plugin name="Storage" value="org.apache.cordova.Storage"/>
    <plugin name="Temperature" value="org.apache.cordova.TempListener"/>
    <plugin name="FileTransfer" value="org.apache.cordova.FileTransfer"/>
    <plugin name="Capture" value="org.apache.cordova.Capture"/>
    <plugin name="Battery" value="org.apache.cordova.BatteryListener"/>
    <plugin name="SplashScreen" value="org.apache.cordova.SplashScreen"/>
    <plugin name="Echo" value="org.apache.cordova.Echo" />
    <plugin name="EmailComposer" value="com.dinesh.pb.EmailComposer"/>
 </plugins>
</cordova>

步骤6：创建一个名为email.js的新javascript文件

var EmailComposer = function(){};
/*
cordova.addConstructor(function() {
    cordova.addPlugin("emailcomposer", new EmailComposer());
});
*/
EmailComposer.prototype.send = function (message){
console.log("Calling the send message");
cordova.exec(function(){ alert('feedback sent')}, 
    function(){ alert('feedback was not sent')}, 
    'EmailComposer', 
    'sendEmail', 
    [message]);
}
function sendFeedback(){
    window.EmailComposer.prototype.send("My message body");
}

正如我之前提到的，我使用的是cordova-2.1.0.js / jar文件，最新版本和旧版本（cordova-1.9.0）之间存在细微差别。如果您使用的是旧版本，则需要取消注释cordova.addConstructorabove部分，而不是调用

window.EmailComposer.prototype.send("My message body");
Use this:
window.plugins.emailComposer.prototype.send(body);

如果你不使用它，那么你可能会收到错误，即没有定义window.plugins。如果您遇到此类问题，请使用firebug并查看“window”变量下定义的变量。

注意名为“feedback（）”的方法。我只是通过捕获用户反馈TextBox的输入将用户文本作为消息体传递。为简单起见，我刚刚粘贴了一个默认的电子邮件正文。

步骤7：在index.html文件中包含js文件

// <!–[CDATA[
javascript" src="js/email.js">
// ]]>

步骤8：在index.html中包含cordova js文件

// <!–[CDATA[
javascript" src="js/cordova-2.1.0.js">
// ]]>

步骤9：为Java邮件api添加三个jar文件 - 即libs文件夹中的Activation.jar，Mail.jar和Additional.jar，并将其添加到类路径中。你可以在这里找到这些文件。

干杯!!
