I have been studying the development of this WeChat public platform in the past few days
I am using chooseImageInterface Called to obtain the picture but it was never displayed. Some posts on Baidu did not turn out very well. Later, I finally figured out how to display it. Now I write it down. Make a backup
Some problems encountered when using WeChatJSDK
When configuring the S interfacesecuritydomain name, you need to use the first-level domain name. You cannot Use a second-level domain name, and cannot bring http or https
For example, in my testUploadimage URL is
//html里的主要代码 <body ontouchstart=""> 上传图片的测试 图像接口 <span class="desc">拍照或从手机相册中选图接口</span> <button class="btn btn_primary" id="chooseImage" onclick="chooseImg_Opinion()">chooseImage</button> <span>图片预览</span> <p id="photo"></p> </body> //js里的主要代码 <script> wx.ready(function () { //自动执行的 wx.checkJsApi({ jsApiList: [ 'chooseImage', ], success: function (res) { // alert(JSON.stringify(res)); // alert(JSON.stringify(res.checkResult.getLocation)); // if (res.checkResult.getLocation == false) { // alert('你的微信版本太低,不支持微信JS接口,请升级到最新的微信版本!'); // return; // } } }); }); wx.error(function (res) { alert(res.errMsg); }); function chooseImg_Opinion() { wx.chooseImage({ success: function (res) { showImgs_Opinion(res); } }); } function showImgs_Opinion(res) { //主要是这一块的代码 var parent = document.getElementById('photo'); var p = document.createElement("p"); //设置 p 属性,如 id p.setAttribute("id", "imgp"); var _html=""; for(var i in res.localIds){ var photoSrc=res.localIds[i]; _html=_html+' 图片'+i+':<img src="'+photoSrc+'" height="200" width="200" />\n'; } p.innerHTML = _html; parent.appendChild(p); </script>
