        User user = new User();
        user.setId("1");
        user.setName(str);
        return user;
	}
}

将以上代码中上面的一个字符串(即带data:image/jpeg;base64,)复制到http://www.jsons.cn/img2base64中然后点击追加img标签即可将base64字符串转为图片
postman base64,java基础,java,postman,base64

postman中通过base64转成图片呢？
postman请求中返回的是base64字符串
postman base64,java基础,java,postman,base64

然后在Tests中输入如下代码然后在直接查看即可


// 将接口返回数据赋值处理
var data = {
    response: pm.response.json()
}
// html 模板字符
// 如果base64代码中已包含“data:image/jpg;base64,”，需要在base64代码前面加上，如下：
var template = `<html><img src="data:image/jpg;base64,{{response.name}}" /></html>`;
// 设置 visualizer 数据。传模板并解析对象。
pm.visualizer.set(template, data);
