流程概述：
利用微信小程序自带的wx.uploadFile方法，将文件post 到服务器API接口，接受内容，保存

为什么实例里边没有将 content-type 为 multipart/form-data 放进去呢，想不懂

直接上代码
js 文件
/选择上传图片
bindUploadTap:function(){
let that = this
wx.chooseImage({
count: 1, // 默认9
sizeType: ['original', 'compressed'], // 可以指定是原图还是压缩图，默认二者都有
sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机，默认二者都有
success: function (res) {
// 返回选定照片的本地文件路径列表，tempFilePath可以作为img标签的src属性显示图片
var tempFilePaths = res.tempFilePaths
that.setData({
imgsrc: tempFilePaths[0]
})
wx.uploadFile({
header: {
'content-type': 'multipart/form-data'
},
url: '/api/v1/Index/upload_img', //仅为示例，非真实的接口地址
filePath: tempFilePaths[0],
name: 'logo',
formData: {
'user': 'test'
},
success: function (res) {
var data = res.data
console.log(res)
//do something
}
})
}
})
},
wxml
选择图片
Laravel 控制器代码
/*
* 上传图片测试
*/
public function upload_img(Request $request)
{
if(!empty($_FILES['logo'])){
Log::info($_FILES["logo"]["type"]."---".$_FILES["logo"]["name"]."---".$_FILES["logo"]["size"]);
$uploaddir = 'app/public/uploads/';
$uploadfile = $uploaddir . basename($_FILES['logo']['name']);
Log::info($uploadfile);
if (move_uploaded_file($_FILES['logo']['tmp_name'], storage_path($uploadfile))) {
Log::info( "File is valid, and was successfully uploaded.\n");
} else {
Log::info( "Possible file upload attack!\n");
}
}
$ret['err'] = 0;
$ret['msg'] = '成功';
return response()->json($ret, $this->successStatus);
}
