ILES:{"food_image":{"name":"jpeg","type":"image\/jpeg","tmp_name":"\/tmp\/php1svqDs","error":0,"size":9561}} POST: {"restaurant_id":"0","tags":"","longitude":"0","latitude":"0","city":"%E5%8C%97%E4%BA%AC","name":"%E0%B8%9B%E0%B8%B1%E0%B8%81%E0%B8%81%E0%B8%B4%E0%B9%88%E0%B8%87"} city: 北京 name: ปักกิ่ง latitude: 0 longitude: 0 restaurant_id: 0
可以看到，所有数据都正常输出，其中POST 数据中 city 和 name未解码前是 urlencode 编码形式的数据，解码后正常输出．
至此，我想使用小程序上传带文件信息到服务器端算是调通了， 希望这个方法能对出现同样问题的同学有一定帮助。
