设置Golbals变量

打开postman — ADD

输入变量名和对应的初始值

设置完成之后 ，点击【保存】
可以看到已经保存到变量中

form中使用变量

使用变量的时候 使用 {{变量名}} 来引用变量。

表单中使用变量也是直接使用{{}} 来引用变量。

json数据中使用变量

{
    "accesstoken":"{{token}}",
    "content":"哈哈哈哈哈哈哈"
}

在json数据中也是使用 {{token}} 引用变量。

上下游传参

1. 接口之间有先后执行的顺序；
2. 接口之间会有具体的数据字段进行关联 （一般情况下这个数据是唯一的）

上下游传参 主要就是指 两个或者两个以上的接口在测试的过程中，之间存在执行的先后顺序和关联；我们在处理这些接口的时候就要把这些接口关联起来。

相关名词：

• 上下游关联
• 参数关联
• 报文关联（多接口中的报文是怎么处理的， 这里说的报文统称 请求的参数和服务器返回的数据）

上面这些都是同一个意思；

处理上下游关联

1. 确定执行顺序；

下面以 发布话题—新建评论接口为例：

创建发布话题请求

还是原来的操作方式，根据文档做即可。

创建 新建评论接口

还是使用原来的方式来创建。

设置变量进行传参

每次发布话题都会产生新的topicid, 需要设置一个变量，每次产生新的id的时候 变量值能够自动更新。 动态设置变量。原来使用手工方式设置变量的值是固定的，已经不能满足当前的场景。

需要使用代码的方式来进行传参。

topicid 是在 创建话题上产生的，所以在创建话题上面写代码；

对应的代码。

// 1. 获取服务器返回的结果   (固定通用的)
var jsondata = pm.response.json();
// 2. 将topic_id 值设置为 postman的全局变量 tid
pm.globals.set("tid",jsondata.topic_id);

下游接口中引用变量

执行接口
【选择 save response】

可以看到执行的结果。

总结

上下游传参主要根据业务需求来做。
做法：

1. 先确定上下游关系，确定执行顺序
2. 在上游接口上设置变量。
3. 下游接口中使用变量。

练习：

1. 新建主题

2. 编辑主题

3. 主题详情

上下游关联.postman_collection.json

练习

前提条件：

1. 设置两个token 变量 | token1 | 3de0a400-5289-49fa-8460-9270d91d5abb | | —- | —- | | token2 | 使用自己的token |

完成如下操作

1. token1 用户 创建话题 — 创建话题请求
2. token2 评论 token1 的话题 — 新建评论
3. token1 回复 token2 的评论 — 新建评论
4. token1 对token2 的评论点赞 — 为评论点赞
5. token2 收藏了token1的话题 — 收藏话题接口

1. 创建两个token 变量

1. 定义创建话题接口

设置变量传参

对应的代码

var jsondata = pm.response.json();
pm.globals.set('tid',jsondata.topic_id);

1. 新建评论

将评论id设置为变量；

var jsondata = pm.response.json();
pm.globals.set('rid',jsondata.reply_id);

1. 对评论进行回复

1. 点赞评论

1. 收藏话题

上面对应的代码附件
参数关联.postman_collection.json
变量.postman_globals.json

为什么要使用上下游传参？

当在测试过程中，如果一个业务涉及到的接口特别多。手工一个一个测试也可以，就是当有关联的参数的时候，比如下订单，订单号每次都是唯一。不能对同一个订单进行重复支付。所以手工测试的话，就需要你手动的一个一个复制，对于测试效率很低。

使用上下游传参，可以显著的提高测试的效率。

复杂字段中提取变量

服务器返回结果的字段值特别多。
