前几天做了图片上传功能,被坑了一下。我们来看一下微信的上传api。
这里的filePath就是图片的存储路径,类型居然是个String,也就是 只能每次传一张图片,我以前的接口都是接收一个array,我本人又是一个半吊子的php,只能自己去改接收图片的接口。
一个很常见的修改头像效果,选择图片(拍照),然后上传。
<view class="xd-container">
<form bindsubmit="bindSaveTap">
<image class="xd-img-user1" catchtap="chooseImageTap" src="{{logo}}"></image>
<view class="xd-view-section">
<text class="xd-abs xd-flex-left xd-text-nick">昵称</text>
<input name="nick_name" placeholder="请输入昵称" class="xd-input" value="{{userInfo.user_name}}"/>
</view>
<view class="xd-view-section1">
<text class="xd-abs xd-flex-left xd-text-nick">宝宝性别</text>
<radio-group class="xd-abs xd-radio-group" name="baby_sex">
<label class="xd-label-radio" wx:for="{{sex_items}}" wx:key="item">
<radio color="#3cc975" value="{{item.name}}" wx:if="{{item.name==userInfo.baby_sex}}" checked="true"/>
<radio color="#3cc975" value="{{item.name}}" wx:else checked="false"/>
<text class="xd-radio-text">{{item.value}}</text>
</label>
</radio-group>
</view>
<view class="xd-view-section1">
<text class="xd-abs xd-flex-left xd-text-nick">宝宝年龄</text>
<input placeholder="请输入年龄" wx:if="{{userInfo.baby_age != 0}}" value="{{userInfo.baby_age}}" class="xd-input"/>
<input name="baby_age" placeholder="请输入年龄" wx:else value="" class="xd-input"/>
</view>
<button size="default" class="xd-abs xd-subBtn" formType="submit" hover-class="xd-subBtn-hover">保存</button>
</form>
</view>
css代码我就不贴了,一些样式而已
var util = require(‘../../../utils/util.js‘)
var app = getApp()
Page({
data: {
sex_items: [
{name:‘1‘, value:‘小王子‘},
{name:‘2‘, value:‘小公主‘},
{name:‘0‘, value:‘尚无‘}
],
logo:null,
userInfo: {}
},
//事件处理函数
bindViewTap: function() {
wx.navigateTo({
// url: ‘../logs/logs‘
// url: ‘../load/load‘
})
},
onLoad: function () {
console.log(‘onLoad‘)
var that = this
//调用应用实例的方法获取全局数据
app.getUserInfo(function(userInfo){
//更新数据
console.log(userInfo);
that.setData({
userInfo:userInfo,
logo:userInfo.logo
})
})
},
bindSaveTap: function(e){
console.log(e)
var formData = {
uid:util.getUserID(),
user_name:e.detail.value.nick_name,
baby_sex:e.detail.value.baby_sex,
baby_age:e.detail.value.baby_age
}
console.log(formData)
app.apiFunc.upload_file(app.apiUrl.modify_user, this.data.logo, ‘photos‘, formData,
function(res){
console.log(res);
},
function(){
})
},
chooseImageTap: function(){
let _this = this;
wx.showActionSheet({
itemList: [‘从相册中选择‘, ‘拍照‘],
itemColor: "#f7982a",
success: function(res) {
if (!res.cancel) {
if(res.tapIndex == 0){
_this.chooseWxImage(‘album‘)
}else if(res.tapIndex == 1){
_this.chooseWxImage(‘camera‘)
}
}
}
})
},
chooseWxImage:function(type){
let _this = this;
wx.chooseImage({
sizeType: [‘original‘, ‘compressed‘],
sourceType: [type],
success: function (res) {
console.log(res);
_this.setData({
logo: res.tempFilePaths[0],
})
}
})
}
})
主要讲解一下JS代码
1、chooseImageTap方法
用来显示一个选择图片和拍照的弹窗,用到了微信的一个页面交互的api showActionSheet,点击查看详细使用
显示操作菜单
2、chooseWxImage方法
主要是用来选择图片以及接收图片路径回调的监听,点击查看详细使用
从本地相册选择图片或使用相机拍照
3、上传
在chooseWxImage方法的success回调中我们可以看到,我把返回的图片路径res.tempFilePaths[0] 赋值给了logo,下面我们只需要调用upload方法就ok了,微信的uploadFile方法被我封装了一下变成了upload_file。
//上传文件
function upload_file(url, filePath, name, formData, success, fail) {
console.log(‘a=‘+filePath)
wx.uploadFile({
url: rootUrl + url,
filePath:filePath,
name:name,
header: {
‘content-type‘:‘multipart/form-data‘
}, // 设置请求的 header
formData: formData, // HTTP 请求中其他额外的 form data
success: function(res){
console.log(res);
if(res.statusCode ==200 && !res.data.result_code){
typeof success == "function" && success(res.data);
}else{
typeof fail == "function" && fail(res);
}
},
fail: function(res) {
console.log(res);
typeof fail == "function" && fail(res);
}
})
}
filePath就是upload_file中我们传进来的logo变量,也就是图片的绝对路径。
看过我上篇文章的都知道 我服务器用的是php框架是Laravel。
只贴一下接收image的代码
if(!empty($_FILES[‘photos‘])){
$up_arr[‘logo‘] = upload_logo(‘photos‘,‘manage/images/user‘,‘logo‘,$user_id,0);
$up_arr[‘logo‘] = $up_arr[‘logo‘][0];
$user_info[‘logo‘] = $Server_Http_Path . $up_arr[‘logo‘];
}
核心方法在upload_log中
if( !function_exists(‘upload_logo‘)){
function upload_logo( $key_name=‘photos‘, $logo_path=‘manage/images/nurse‘, $pre_name=‘logo‘, $salt=‘20160101‘,$encode = 1,$make=0 ){
$result_arr = array();
global $Server_Http_Path,$App_Error_Conf;
//分文件夹保存
$date_info = getdate();
$year = $date_info[‘year‘];
$mon = $date_info[‘mon‘];
$day = $date_info[‘mday‘];
$logo_path = sprintf("%s/%s/%s/%s",$logo_path,$year,$mon,$day);
if(!is_dir($logo_path)){
$res=mkdir($logo_path,0777,true);
}
//图片上传
//foreach($photos as $key => $photo ){
$photo = $_FILES[‘photos‘];
$name = $key_name;
$file_id = Input::file($name);
if(!empty($file_id) && $file_id -> isValid()){
$entension = $file_id -> getClientOriginalExtension();
if($pre_name == ‘baby‘){
$new_name = $pre_name . "_" . intval($salt) ."_" .time() . "_" . salt_rand(2,2);
}else {
$new_name = $pre_name . "_" . intval($salt) ."_" . salt_rand(2,2);
}
$path_id = $file_id -> move($logo_path,$new_name."_b.".$entension);
if(!empty($path_id)){
$path_name = $path_id->getPathName();
$image_size=getimagesize($path_name);
$weight=$image_size["0"];////获取图片的宽 $height=$image_size["1"];///获取图片的高
if($pre_name == "baby" || $pre_name == "video") { $photo_info[‘url‘] = $path_name; $photo_info[‘width‘] = $weight;
$photo_info[‘height‘] = $height;
$result_arr[] = $photo_info;
}else{
$result_arr[] = $path_name;
}
//处理图片
if($make == 1){
$img = Image::make($path_name)->resize(200, $height*200/$weight);
$img->save($logo_path ."/".$new_name."_s.".$entension);
//dd($img);
// return $img->response(‘jpg‘);
}
}
if(empty($result_arr)){
$response[‘result_code‘] = -1006;
$response[‘result_msg‘] = $App_Error_Conf[-1006];
return response($response);
}
if($encode == 1){
$result_arr = json_encode($result_arr);
}
}
return $result_arr;
}
}
这个代码格式真的很烦人啊,我就大概整理了一下。
