接入智齿客服网页端流程：
主要问题就是Android webview 屏蔽了上传文件功能，本文附带解决了WebView 不支持<input type=file>文件上传，WebView 点击没有反应的问题；
智齿客服网页端接入有两种部署方式。1、网页组件；2、聊天链接。本文档不涉及业务流程，只讲述开发接入过程；
今天主要说一下Android 、ios 对 聊天链接这种方式的接入，第一种接入方式后期再做描述。
1、 先注册智齿客服，然后用超级管理员账号登陆后到“设置-支持渠道”获取部署代码；
例：获取聊天链接如下：
/chat/pc/index.html?sysNum=a047ca3c8fec47cca963d4a6e27b8706
2、这是智齿客服官方提供的链接开发文档：智齿客服官方文档，文档最后列出了聊天链接可以拼接的参数，可根据需要自行配置，值得注意的是customerFields字段，是智齿客服提供的允许自定义的字段，登入智齿客服官网 到“设置-自定义字段” 中设置你所需要的字段。
例如新建字段名称为“游戏”，点击“显示ID”,查看自定义字段所对应的参数。最后将自定义字段拼接成json字符串，拼接到链接后面。如下：
拼接链接如下：/chat/pc/index.html?sysNum=a047ca3c8fec47cca963d4a6e27b8706&customerFileds={"customField1":"麻将","customField2":"北京"}
3、通过Android或IOS ， webview 加载此链接。说明：ios 不需要做任何更改，直接加载链接就可以使用智齿客服网页版的聊天链接了。Android直接加载无法上传图片和拍照。
4、Android 上传图片和拍照问题解决；
由于安全因素android webview屏蔽了文件上传控件，但是他并没有完全封掉。
解决方法步骤如下：
（1）、Activity 定义：
private static final int REQUEST_CODE_PERMISSION_CAMERA = 0x03;private static final int REQUEST_CODE_CAMERA = 0x02;private static final int REQUEST_CODE_ALBUM = 0x01;private ValueCallback<Uri[]> uploadMessageAboveL;private ValueCallback<Uri> uploadMessage;
（2）、扩展WebChromeClient
webView.setWebChromeClient(mWebChromeClient);protected WebChromeClient mWebChromeClient = new WebChromeClient() {@Overridepublic void onReceivedTitle(WebView view, String title) {super.onReceivedTitle(view, title);if (basetitle != null && !TextUtils.isEmpty(title)) {basetitle.setText(title);} else {basetitle.setText(" ");}}// For Android 4.1 - 5.0@Overridepublic boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> valueCallback, FileChooserParams fileChooserParams) {uploadMessageAboveL = valueCallback;uploadPicture();return true;}// For Android >= 5.1@Overridepublic void openFileChooser(ValueCallback<Uri> valueCallback, String s, String s1) {//super.openFileChooser(valueCallback, s, s1);uploadMessage = valueCallback;uploadPicture();}};
（3）、解决选择文件后按钮失效问题，需要覆写onActivityResult方法
@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (requestCode == REQUEST_CODE_ALBUM || requestCode == REQUEST_CODE_CAMERA) {if (uploadMessage == null && uploadMessageAboveL == null) {return;}//取消拍照或者取消选择相册if (resultCode != RESULT_OK) {if (uploadMessage != null) {uploadMessage.onReceiveValue(null);uploadMessage = null;}if (uploadMessageAboveL != null) {uploadMessageAboveL.onReceiveValue(null);uploadMessageAboveL = null;}}//拍照成功或选择照片if (resultCode == RESULT_OK) {Uri imageUri = null;switch (requestCode) {case REQUEST_CODE_ALBUM:if (data != null) {imageUri = data.getData();}break;case REQUEST_CODE_CAMERA:if (!TextUtils.isEmpty(mCurrentPhotoPath)) {File file = new File(mCurrentPhotoPath);Uri loadUri = Uri.fromFile(file);Intent localIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, loadUri);sendBroadcast(localIntent);imageUri = Uri.fromFile(file);mLastPhotoPath = mCurrentPhotoPath;}break;}//上传文件if (uploadMessage != null) {uploadMessage.onReceiveValue(imageUri);uploadMessage = null;}if (uploadMessageAboveL != null) {uploadMessageAboveL.onReceiveValue(new Uri[]{imageUri});uploadMessageAboveL = null;}}}}
（4）、以上是主要功能点，下面是我自己用到的一个完整文件，可以参考，里面内容部分多余的请自动忽略。

5、智齿客服聊天链接接入完毕。总结一下，主要要处理的一个问题就是Android webview 屏蔽了文件上传。解决了这个问题也就完全解决了，说明一下，选择拍照或者相册的弹窗，可以自己根据需要自己重新写一下UI样式。
