I have been studying the development of this WeChat public platform in the past few days
I am using chooseImage Interface 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

applinzi.com

//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="&#39;+photoSrc+&#39;" height="200" width="200" />\n';
    }
　　p.innerHTML = _html;
　　parent.appendChild(p);
 </script>
