1.微信端向伺服器傳送上傳請求

wx.chooseImage({
      success: function (res) {
        var tempFilePaths = res.tempFilePaths
        console.log(tempFilePaths[0])
        wx.uploadFile({
          url: 'http://xxxx/xxx/xx',
          filePath: tempFilePaths[0],
          name: "rawPic",
          
        })
      }
    })

  
 

2.伺服器控制器

    @PostMapping("/uploadPic")
	public Result uploadPic(					
			@RequestParam(required=true,name="rawPic")
			MultipartFile file
			
			)
	{
		String path = write.writePicPath();
		Result result = new Result();
		result.setCode(1);
		result.setMessage(write.getFilepPath()+"\\"+path);
		
		

try {
	file.transferTo(new File(write.getFilepPath()+"\\"+path));
} catch (IllegalStateException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
} catch (IOException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
}
		
return result;

	}
 

看不懂伺服器程式碼的同學可以參考我的springboot的相關部落格

現在要說的是，springboot支援直接返回物件，物件的所有欄位全部通過getset訪問器 設定為屬性，將會以json格式傳給客戶端，所以你根本不用操心在伺服器端怎麼轉json！

這是返回物件的程式碼

public class Result {
    private int code;
    private String message;
    private Object data;

    public Result setCode(ResultCode resultCode) {
        this.code = resultCode.code;
        return this;
    }

    public int getCode() {
        return code;
    }

    public Result setCode(int code) {
        this.code = code;
        return this;
    }

    public String getMessage() {
        return message;
    }

    public Result setMessage(String message) {
        this.message = message;
        return this;
    }

    public Object getData() {
        return data;
    }

    public Result setData(Object data) {
        this.data = data;
        return this;
    }

    @Override
    public String toString() {
        return JSON.toJSONString(this);
    }
}
 

3.客戶端可以通過轉json格式獲取裡面的資料，就像讀字典一樣，超級爽!

success(res)
          {
            console.log(JSON.parse(res.data)['message']);
          }
