1.微信端向服务器发送上传请求

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.服务器控制器

    @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;

	}

看不懂服务器代码的同学可以参考我的springboot的相关博客

现在要说的是,springboot支持直接返回对象,对象的所有字段全部通过getset访问器 设置为属性,将会以json格式传给客户端,所以你根本不用操心在服务器端怎么转json!

 

这是返回对象的代码

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.客户端可以通过转json格式获取里面的数据,就像读字典一样,超级爽!

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