+
+
+    This file creates a global JSON object containing two methods: stringify
+    and parse.
+
+        JSON.stringify(value, replacer, space)
+            value       any JavaScript value, usually an object or array.
+
+            replacer    an optional parameter that determines how object
+                        values are stringified for objects. It can be a
+                        function or an array of strings.
+
+            space       an optional parameter that specifies the indentation
+                        of nested structures. If it is omitted, the text will
+                        be packed without extra whitespace. If it is a number,
+                        it will specify the number of spaces to indent at each
+                        level. If it is a string (such as '\t' or ' '),
+                        it contains the characters used to indent at each level.
+
+            This method produces a JSON text from a JavaScript value.
+
+            When an object value is found, if the object contains a toJSON
+            method, its toJSON method will be called and the result will be
+            stringified. A toJSON method does not serialize: it returns the
+            value represented by the name/value pair that should be serialized,
+            or undefined if nothing should be serialized. The toJSON method
+            will be passed the key associated with the value, and this will be
+            bound to the value
+
+            For example, this would serialize Dates as ISO strings.
+
+                Date.prototype.toJSON = function (key) {
+                    function f(n) {
+                        // Format integers to have at least two digits.
+                        return n < 10 ? '0' + n : n;
+                    }
+
+                    return this.getUTCFullYear()   + '-' +
+                         f(this.getUTCMonth() + 1) + '-' +
+                         f(this.getUTCDate())      + 'T' +
+                         f(this.getUTCHours())     + ':' +
+                         f(this.getUTCMinutes())   + ':' +
+                         f(this.getUTCSeconds())   + 'Z';
+                };
+
+            You can provide an optional replacer method. It will be passed the
+            key and value of each member, with this bound to the containing
+            object. The value that is returned from your method will be
+            serialized. If your method returns undefined, then the member will
+            be excluded from the serialization.
+
+            If the replacer parameter is an array of strings, then it will be
+            used to select the members to be serialized. It filters the results
+            such that only members with keys listed in the replacer array are
+            stringified.
+
+            Values that do not have JSON representations, such as undefined or
+            functions, will not be serialized. Such values in objects will be
+            dropped; in arrays they will be replaced with null. You can use
+            a replacer function to replace those with JSON values.
+            JSON.stringify(undefined) returns undefined.
+
+            The optional space parameter produces a stringification of the
+            value that is filled with line breaks and indentation to make it
+            easier to read.
+
+            If the space parameter is a non-empty string, then that string will
+            be used for indentation. If the space parameter is a number, then
+            the indentation will be that many spaces.
+
+            Example:
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}]);
+            // text is '["e",{"pluribus":"unum"}]'
+
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+            text = JSON.stringify([new Date()], function (key, value) {
+                return this[key] instanceof Date ?
+                    'Date(' + this[key] + ')' : value;
+            });
+            // text is '["Date(---current time---)"]'
+
+
+        JSON.parse(text, reviver)
+            This method parses a JSON text to produce an object or array.
+            It can throw a SyntaxError exception.
+
+            The optional reviver parameter is a function that can filter and
+            transform the results. It receives each of the keys and values,
+            and its return value is used instead of the original value.
+            If it returns what it received, then the structure is not modified.
+            If it returns undefined then the member is deleted.
+
+            Example:
+
+            // Parse the text. Values that look like ISO date strings will
+            // be converted to Date objects.
+
+            myData = JSON.parse(text, function (key, value) {
+                var a;
+                if (typeof value === 'string') {
+                    a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+                    if (a) {
+                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+                            +a[5], +a[6]));
+                    }
+                }
+                return value;
+            });
+
+            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+                var d;
+                if (typeof value === 'string' &&

+
+发送图片消息sdk自动分两步完成：<br>
+1）上传图片文件到服务器，并得到服务返回的图片信息等<br>
+2）发送图片消息，消息体包含图片的基本信息、服务器路径、secret等，接收方初始化连接中的onPictureMessage的格式，根据图片消息内容到服务器下载图片，并进行显示
+
+<pre class="hll"><code class="language-javascript">

+
+### 发送音频消息{#sendAudio}
+
+sdk处理同发送图片消息，分两步：
+
+1. 上传音频文件到服务器，得到音频文件的信息；
+2. 发送音频消息给接收方，消息体包含音频的基本信息、下载路径和secret信息等，接收方收到消息后，根据消息体内部的音频下载路径和secret路径，下载音频并进行显示。
+
+<pre class="hll"><code class="language-javascript">
+function sendAudio () {
+    var to = curChatUserId;
+    if (to == null) {

+
+### 接收消息
+
+#### 注册接收消息 {#onmessage}
+
+<pre class="hll"><code class="language-javascript">
+conn.init({
+	onTextMessage : function(message) {        },//收到文本消息处理动作
+    onEmotionMessage : function(message) {        },//收到表情消息处理动作

+    onAudioMessage : function(message) {        }, //收到语音消息处理动作
+	...
+});
+</code></pre>
+
+#### 处理消息{#options}
+
+conn.init()中注册不同消息接收handler之后，可自行解析消息体，定位聊天好友，并追加到与其聊天窗口。具体参考webim.easemob.com效果，消息体格式参见前章节：初始化连接。<br>
+注：对于图片、语音消息需要先进行下载，然后进行显示或者播放处理。如下(下载图片，音频同)：
+<pre class="hll"><code class="language-javascript">
+var handlePictureMessage = function(message) {
+var filename = message.filename;//文件名称，带文件扩展名
+var from = message.from;//文件的发送者
+var mestype = message.type;//消息发送的类型是群组消息还是个人消息
+......
+...
+var options = message;
+// 图片消息下载成功后的处理逻辑
+options.onFileDownloadComplete = function(response, xhr) {
+	var objectURL = window.URL.createObjectURL(response);
+	img = document.createElement("img");
+	img.onload = function(e) {
+		img.onload = null;
+		window.URL.revokeObjectURL(img.src);
+	};
+	img.onerror = function() {
+		img.onerror = null;
+		if (typeof FileReader == 'undefined') {
+			img.alter = "当前浏览器不支持blob方式";
+			return;
+		}
+		img.onerror = function() {
+			img.alter = "当前浏览器不支持blob方式";
+		};
+		var reader = new FileReader();
+		reader.onload = function(event) {
+			img.src = this.result;
+		};
+		reader.readAsDataURL(response);
+	}
+	img.src = objectURL;
+	var pic_real_width = options.width;
+	......
+	...
+};
+options.onFileDownloadError = function(e) {
+	appendMsg(from, contactDivId, e.msg + ",下载图片" + filename + "失败");
+};
+Easemob.im.Helper.download(options);
+
+</code></pre>
+
+#### 历史消息{#history_message}
+
+sdk暂不具有缓存历史消息功能，demo中聊天窗口只能显示，当前登录后会话实时在聊天信息，不能查看历史消息，可以对登录后的聊天信息进行清除操作。
+
+#### 新消息提示{#new_message}
+
+sdk在收到新消息是会直接转发给登录用户，接收到消息后，demo中会在好友或者群组的后面显示红色消息数，具体样式开发者可自行处理。

+
+/** Constructor: Strophe.Connection
+ *  Create and initialize a Strophe.Connection object.
+ *
+ *  The transport-protocol for this connection will be chosen automatically
+ *  based on the given service parameter. URLs starting with "ws://" or
+ *  "wss://" will use WebSockets, URLs starting with "http://", "https://"
+ *  or without a protocol will use BOSH.
+ *
+ *  To make Strophe connect to the current host you can leave out the protocol
+ *  and host part and just pass the path, e.g.
+ *
+ *  > var conn = new Strophe.Connection("/http-bind/");
+ *
+ *  WebSocket options:
+ *
+ *  If you want to connect to the current host with a WebSocket connection you
+ *  can tell Strophe to use WebSockets through a "protocol" attribute in the
+ *  optional options parameter. Valid values are "ws" for WebSocket and "wss"
+ *  for Secure WebSocket.
+ *  So to connect to "wss://CURRENT_HOSTNAME/xmpp-websocket" you would call
+ *
+ *  > var conn = new Strophe.Connection("/xmpp-websocket/", {protocol: "wss"});
+ *
+ *  Note that relative URLs _NOT_ starting with a "/" will also include the path
+ *  of the current site.
+ *
+ *  Also because downgrading security is not permitted by browsers, when using
+ *  relative URLs both BOSH and WebSocket connections will use their secure
+ *  variants if the current connection to the site is also secure (https).
+ *
+ *  BOSH options:
+ *
+ *  by adding "sync" to the options, you can control if requests will
+ *  be made synchronously or not. The default behaviour is asynchronous.
+ *  If you want to make requests synchronous, make "sync" evaluate to true:
+ *  > var conn = new Strophe.Connection("/http-bind/", {sync: true});
+ *  You can also toggle this on an already established connection:
+ *  > conn.options.sync = true;
+ *
+ *
+ *  Parameters:
+ *    (String) service - The BOSH or WebSocket service URL.
+ *    (Object) options - A hash of configuration options
+ *
+ *  Returns:
+ *    A new Strophe.Connection object.
