工作中需要將用戶頭像上傳到服務(wù)器。

需要這么幾步：

1，點(diǎn)擊img元素彈出Popup，選擇拍照或從圖片庫中選擇圖片。

2，上傳圖片

在phonega中拍照需要camera插件。
上傳文件需要file-transfer插件。

我在工程中安裝的所有插件如下：

    
        cordova plugin add org.apache.cordova.device
	cordova plugin add org.apache.cordova.network-information
	cordova plugin add org.apache.cordova.battery-status
	cordova plugin add org.apache.cordova.geolocation
	cordova plugin add org.apache.cordova.dialogs
	cordova plugin add org.apache.cordova.camera
	cordova plugin add org.apache.cordova.media-capture
	cordova plugin add org.apache.cordova.media
	cordova plugin add org.apache.cordova.vibration
	cordova plugin add org.apache.cordova.globalization
	cordova plugin add org.apache.cordova.splashscreen
	cordova plugin add org.apache.cordova.inappbrowser
	cordova plugin add org.apache.cordova.file-transfer

  

下面完成第一步：
建立img元素，當(dāng)點(diǎn)擊該元素的時(shí)候跳轉(zhuǎn)到#select_pic_page，#select_pic_page是個(gè)popup，
使用JQM是如下寫法：

    
<div>
	<a href="#select_pic_page" data-rel="popup" data-position-to="window" data-transition="pop"><img id="face" style="width:110px;height:110px;" src="img/default_face.jpg" /></a>
	<div data-role="popup" id="select_pic_page" data-overlay-theme="a">
		<ul data-role="listview" data-icon="false">
			<li onclick="onFaceImgClick(0)" style="border-width:0;border-color:#666;border-bottom-width: 1px;"><a style="padding:16px;font-weight:normal;" href="#" data-rel="back">Take a picture</a></li>
			<li onclick="onFaceImgClick(1)" style="border-width:0;"><a style="padding:16px;font-weight:normal;" href="#" data-rel="back">Select From Photo Library</a></li>
		</ul>
	</div>			
</div>

  

點(diǎn)擊popup中的選項(xiàng)，第一個(gè)是臨時(shí)拍照，第二項(xiàng)是從圖片庫中選擇，用flag區(qū)分。

    
function onFaceImgClick(flag){
//	var w=$("#my_profile_page #face").width();
//	var h=$("#my_profile_page #face").height();
	var w=440;
	var h=440;
	
	var quality = device.platform=="Android"?100:50;
//	log("device.platform="+device.platform+";quality====="+quality);
	var cameraOptions;
	if(flag==0){
		cameraOptions={	
				quality : quality,//ios為了避免部分設(shè)備上出現(xiàn)內(nèi)存錯(cuò)誤，quality的設(shè)定值要低于50。
				destinationType : Camera.DestinationType.FILE_URI,//FILE_URI,DATA_URL
				sourceType : Camera.PictureSourceType.CAMERA,//CAMERA,SAVEDPHOTOALBUM
				allowEdit : true,
				encodingType : Camera.EncodingType.JPEG,//JPEG,PNG
				targetWidth : w,
				targetHeight : h
		};
	}else{
		cameraOptions={	
				quality : quality,//ios為了避免部分設(shè)備上出現(xiàn)內(nèi)存錯(cuò)誤，quality的設(shè)定值要低于50。
				destinationType : Camera.DestinationType.FILE_URI,//FILE_URI,DATA_URL
				sourceType : Camera.PictureSourceType.PHOTOLIBRARY,//CAMERA,SAVEDPHOTOALBUM
				allowEdit : true,
				encodingType : Camera.EncodingType.JPEG,//JPEG,PNG
				targetWidth : w,
				targetHeight : h
		};
	}
	navigator.camera.getPicture( onCameraSuccess, onCameraError, cameraOptions);
}

  

獲取圖片成功后執(zhí)行回調(diào)函數(shù)onCameraSuccess，參數(shù)imageURI是拍照成功后返回的圖片路徑

    
function onCameraSuccess(imageURI){//imageData
//	log("data==="+imageURI);
//	$("#my_profile_page #face").attr("src","data:image/jpeg;base64," + imageData);
	
	user.imgOriginalUrl=imageURI;
	$("#my_profile_page #face").attr("src",user.imgOriginalUrl);
//拍照成功后，需要上傳文件
	var fileName=imageURI.substr(imageURI.lastIndexOf('/') + 1);
	var options = new FileUploadOptions();
	options.fileKey = "fieldName";//圖片域名！！！
	if(fileName.indexOf('?')==-1){
		options.fileName = fileName;
	}else{
		options.fileName = fileName.substr(0,fileName.indexOf('?'));
	}
	
	 options.mimeType = "image/jpeg";
	//options.mimeType = "multipart/form-data";
	 options.chunkedMode = false;
	 
	 var params = {};
	 params.sid = user.sid;
	 params.fileType = "customer";
	 options.params = params;
	 
	 var uri = encodeURI(BASE_URL+"phoneCustomer/updateCustomerInfo.action?sid="+user.sid+"&fileType=customer");

	 var ft = new FileTransfer();
	 ft.upload(imageURI, uri, onFileUploadSuccess, onFileUploadFail, options);
}

function onCameraError(message){
	log('Failed because: ' + message);
}

function onFileUploadSuccess(result){
	log("========onFileUploadSuccess===========");
//	log("Code = " + result.responseCode+";Response = " + result.response+";Sent = " + result.bytesSent);
}
function onFileUploadFail(error){
	log("code = "+error.code+";upload error source = " + error.source+";upload error target = " + error.target);
}

  

在ios中，如果點(diǎn)擊無法調(diào)出camera，請(qǐng)務(wù)必執(zhí)行一下命令cordova build ios

phonegap+JQM拍照并上傳頭像到服務(wù)器
