贴心代码详解（一）会讲发帖部分发帖页面
页面看起来还是很简单的，因为服务器大小不够，所以我们设置每个人只能发一张图。在这个页面里java后台负责图片上传，前端给后台图片filePath就OK了。这里使用了iviewweapp组件js代码varapp=getApp()//获取urlPage({data:{img_arr:[],title:'',detail:'',fruit:[{id:1,name:'失物招领',},{id:2,name:'日常交流'},{id:3,name:'创意分享'},{id:4,name:'竞赛组队',}],current:"日常交流"//默认值},handleFruitChange({detail={}}){this.setData({current:detail.value});},formSubmit:function(e){this.upload(e)},/问题：一张图片上传/upload:function(e){/varthat=thiswx.login({success:function(res){wx.request({url:app.globalData.url+'onlogin',//本地调试，是获取不到code的，所以要实现，还是得传服务data:{"code":res.code},header:{'content-type':'application/json'//默认值},success:function(res){console.log(res.data.openid)varOD=res.data.openid以上内容为获取用户openid，可以不要/if(that.data.img_arr[0]==null)//当用户不发图时{wx.request({header:{'content-type':'application/x-www-form-urlencoded'},url:app.globalData.url+'post',data:{'content':e.detail.value.content,'title':e.detail.value.title,'category':that.data.current,"oppidA":OD},method:'POST',success:function(res){if(res){wx.showToast({title:'已提交至管理员审核，请耐心等待！',duration:3000});setTimeout(()={wx.switchTab({url:'../../pages/list/list',})},1000);//发完贴1秒自动跳转到帖子列表页}}})}else{//当用户发图时setTimeout(()={for(vari=0;i(this.data.img_arr.length);i++){console.log(that.data.img_arr[0])wx.uploadFile({url:app.globalData.url+'post',filePath:that.data.img_arr[0],name:'file',header:{'content-type':'application/x-www-form-urlencoded'//一定要用这个},formData:{'content':e.detail.value.content,'title':e.detail.value.title,'category':that.data.current,"oppidA":OD},success:function(res){if(res){wx.showToast({title:'已提交至管理员审核，请耐心等待！',duration:3000});setTimeout(()={wx.switchTab({url:'../../pages/list/list',})},1000);}}})that.setData({formdata:''})},1000);}}})}})},upimg:function(){varthat=this;if(this.data.img_arr.length1){wx.chooseImage({//选择图片count:1,//一张图片sizeType:['original','compressed'],success:function(res){that.setData({img_arr:that.data.img_arr.concat(res.tempFilePaths)})}})}},onLoad:function(){},});json内容部分：
