开发工具：Idea2019.3  
开发环境：SpringBoot2.2+mysql  
接口测试工具：swagger  
1.先看阿里给的api文档

不得不说，这个demo是再简洁明了不过了，直接一个main方法执行就可以，二话不说我就复制了代码，放一个main方法里面，然后…

我第一反应是，肯定缺少依赖，所以没有相应的包，就找不到方法，去百度找一波，还是一脸懵逼  
![在这里插入图片描述][20200113201212178.jpg]

又去看了demo,果然，怪我自己眼瞎，人家专门写了依赖地址的，  
![在这里插入图片描述][20200113201256215.png]  
github上面给了这些依赖

好，弄好了依赖，然后回来看，发现还是报红线，还是找不到方法，我就又。。。。。

只能再好好再看看demo，果然，我是真的瞎，只看了一半，人家清楚的写着重要提示，而我…  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0x5bm5lWm9l_size_16_color_FFFFFF_t_70 4]把人家HttpUtils从github上面down下来，再去像模像样的用身份证照片生成一个BASE64,放进去，准备run一下，果然新的问题又来了，说我base64的字符串常量过长，我当时就想，这几个意思？难道他们用的时候不长？又不能改成Object类型之类的，方法都是封装好的。。。。。。。。。。。百度一波发现，我还是太菜了  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0x5bm5lWm9l_size_16_color_FFFFFF_t_70 5]  
解决方法如下：在生成BASE64的时候会因为字符超级长而换行，所以用String里面的replaceAll()把里面的换行符号去掉就可以了

写了个测试接口测了一下

差别还是有点大的，解决了这个，接着往下，跟着demo，这个亚子就应该能看到效果了

然而，打印了一堆，请求头之类的东西，不过值得注意的是，状态码对了的，200，所以肯定是我接收返回值处理方式不对

这次我果断的直接又去看了demo,然而这次没有漏掉什么了，它除了注释的，，，，，，，，，，等等，它注释了一段，那我把注释的放开看看呢

有那么个意思，但是，汉字全部变成了ASCII 编码的格式，看不懂，所以我又去找了半天“Java怎么将ascll码转为utf-8”,然后试了几个，看起来并没有什么效果  
![在这里插入图片描述][20200113205445220.jpg]  
冷静想一下，emmmmmmmm,他的demo返回值是json格式，而我现在是String,转Json对象试一下呢

这次没有意外，成功了，没错就是要转成json格式，我还是太菜了，记录一下。  
贴一个完整的代码纪念一下
