微信jssdk拍照转base64上传七牛

本文主要是介绍微信jssdk拍照转base64上传七牛，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

API版本:

        调用API需要1.2以上,是指的至少1.3及往上版本.

<script type="text/javascript" src="https://res.wx.qq.com/open/js/jweixin-1.3.0.js"></script>wx.config({debug: false,****验证信息****jsApiList: ['checkJsApi','openLocation','chooseImage','getLocalImgData']});wx.ready(function(){});  wx.checkJsApi({jsApiList: ['checkJsApi','openLocation','chooseImage','getLocalImgData'], // 需要检测的JS接口列表，所有JS接口列表见附录2,success: function(res) {}});

微信拍照及数据转base64方法

function getImage(callback,Classify,btn){wx.chooseImage({count: 1, sizeType: ['compressed'], sourceType: [ 'camera'], success: function (res) {var localIds_val = res.localIds[0]; var imgCode="<img id=\"updateImage\" src=\""+localIds_val+"\">";$(btn).parent().parent().children().eq(1).append(imgCode);wx.getLocalImgData({localId: localIds_val.toString(),//图片的本地IDsuccess: function (res) {var localData = res.localData;//base64QNputb64(localData,callback,Classify,btn);}});}});}

 

苹果base64数据

上传七牛操作

function QNputb64(pic,callback,Classify,btn){var base64 = pic.replace('data:image/png;base64,', '').replace('data:image/jgp;base64,', '');$.ajax({url: "@(Url.Action("GetTourOAUpTokenQN", "SysManage"))",type: "post",dataType: "json",success: function (result) {if (result.IsSuccess) {var url = "http://upload.qiniup.com/putb64/-1"; //非华东空间需要根据注意事项 1 修改上传域名var xhr = new XMLHttpRequest();xhr.onreadystatechange=function(){if (xhr.readyState==4){QNReturn = xhr.responseText;wlog(QNReturn);callback(Classify,btn);}}xhr.open("POST", url, true);xhr.setRequestHeader("Content-Type", "application/octet-stream");xhr.setRequestHeader("Authorization","UpToken "+ result.Data);xhr.send(base64);} else {callback(Classify,btn);}}}); }
