一、html部分
<view class='head_img' bindtap='upShopLogo'>
<text>头像</text>
<view class='img'><image src='{{userimg}}'></image></view>
</view>
二、js部分
1.在data里面设置默认的值
data: {
userimg:'',
nickname:'',
},
2.点击事件触发上传事件
// 点击上传图片
upShopLogo: function () {
var that = this;
wx.showActionSheet({
itemList: ['从相册中选择', '拍照'],
itemColor: "#f7982a",
success: function (res) {
if (!res.cancel) {
if (res.tapIndex == 0) {
that.chooseWxImageShop('album');//从相册中选择
} else if (res.tapIndex == 1) {
that.chooseWxImageShop('camera');//手机拍照
}
}
}
})
},
3.选择图片
chooseWxImageShop: function (type) {
var that = this;
wx.chooseImage({
sizeType: ['original', 'compressed'],
sourceType: [type],
success: function (res) {
that.data.userimg = res.tempFilePaths[0],
that.upload_file(urldate.upimg + 'shop/shopIcon', res.tempFilePaths[0])
userimg = res.tempFilePaths[0];
that.setData({
userimg: userimg
})
}
})
},
4.上传图片到服务器
upload_file: function (url, filePath) {
var that = this;
var signature = signa.signaturetik('token=' + token, 'userAccessToken=' + userAccessToken, 'studentAccessToken=' + studentAccessToken);
wx.uploadFile({
url: urldate.upimg,//后台处理接口
filePath: filePath,
name: 'file',
header: {
'content-type': 'multipart/form-data'
}, // 设置请求的 header
formData: {//需要的参数
'token': token,
'signature': signature,
'userAccessToken': userAccessToken,
'studentAccessToken': studentAccessToken
}, // HTTP 请求中其他额外的 form data
success: function (res) {
var data = JSON.parse(res.data);
that.setData({
userimg: data.path,
});
that.showMessage('上传成功');
},
fail: function (res) {
}
})
},
