现在头像改了，改成不用询问用户权限的

<pre class="prettyprint"><code class=" hljs xml"><span class="hljs-comment">
<span class="hljs-comment">
<span class="hljs-tag"><<span class="hljs-title">open-data <span class="hljs-attribute">type=<span class="hljs-value">"userAvatarUrl"><span class="hljs-tag"></<span class="hljs-title">open-data>
<span class="hljs-tag"><<span class="hljs-title">open-data <span class="hljs-attribute">type=<span class="hljs-value">"userNickName"><span class="hljs-tag"></<span class="hljs-title">open-data>

但是换了之后，这个头像的样式弄了半天，这样写

<pre class="prettyprint"><code class=" hljs css"><span class="hljs-class">.touimage <span class="hljs-rules">{
<span class="hljs-comment">/ 居中 /
<span class="hljs-rule"><span class="hljs-attribute">margin:<span class="hljs-value"> <span class="hljs-number">0 auto;
<span class="hljs-rule"><span class="hljs-attribute">display:<span class="hljs-value"> flex;
<span class="hljs-rule"><span class="hljs-attribute">justify-content:<span class="hljs-value"> center;
<span class="hljs-rule"><span class="hljs-attribute">overflow:<span class="hljs-value"> hidden;
<span class="hljs-rule"><span class="hljs-attribute">width:<span class="hljs-value"> <span class="hljs-number">161rpx;
<span class="hljs-rule"><span class="hljs-attribute">height:<span class="hljs-value"> <span class="hljs-number">161rpx;
<span class="hljs-rule"><span class="hljs-attribute">border-radius:<span class="hljs-value"> <span class="hljs-number">50%;
<span class="hljs-rule">}
