Javascript 邮递员获得Gmail电子邮件ID，通过电子邮件ID进行迭代？

对于postman来说，我是一个新手，在链接API请求时，我从来没有想过要遍历消息ID

我有一个简单的GET请求，如下所示

这没有问题，检索收件箱中的前100封邮件，我使用索引链接到另一个命令来打开该电子邮件，并使用以下代码检查内容

Responsedata = JSON.parse(responseBody)
Value = Responsedata.messages[1].id
console.log(Value)
pm.environment.set("email_id", Value); 

我搞不懂的是如何迭代并在下一次迭代中将消息[1].id从1递增到2？如果你这样描述的话，我从来没有想过要增加变量

JSON响应体

编辑第二部分

然后，我将接收该电子邮件并执行另一个GET请求

---

然后打开并读取电子邮件的内容，这就是为什么我试图将电子邮件id索引从0增加到1，因此每次运行API链时，它都会移动到下一封电子邮件上，我不确定我是否理解该问题，但为了增加

消息[1]的值。id

，只需执行以下操作：

Responsedata.messages[1].id++

这将使

消息[1].id的值（增加一个）增加


否则如果要迭代Responsedata对象中包含的100条消息，可以执行以下操作（因为消息是一个数组）：

Responsedata=JSON.parse（responseBody）
for（设i=0；i

可以将数组或任何内容存储为环境变量。Postman的工作原理与javascript一样

现在您在emailID变量中有了价值。现在，您可以使用setNExtRequest发送带有id的消息请求

如果您的请求名称和结构如下：

首先获取消息，然后获取ID为的消息：


然后在id为的get消息请求中使用以下预请求脚本：

let emailIDList = pm.environment.get("emailID");


pm.environment.set("id", emailIDList.pop())
pm.environment.set("emailID", emailIDList)
if (emailIDList.length > 0) {
    postman.setNextRequest("get Message with id")
}

嗨@Dorian，谢谢你的回复。我想我已经试过了，我回去把它编辑成
Responsedata=JSON.parse（responseBody）Value=Responsedata.messages[1].id++console.log（Value）pm.environment.set（“email_id”，Value）
但是在下一次迭代中它仍然没有获取我收件箱中的下一个ID。也许我仍然实现了这个错误？您能提供一个responseBody json内容的示例吗？这将有助于我们理解这个问题。另外，请注意，
Value=Responsedata.messages[1].id++
，如果我没有错的话，将把
Responsedata.messages[1].id
分配给“Value”变量，并且仅在之后，它将把
Responsedata.messages[1].id
值增加一个。刚刚用响应体更新了原始问题。谢谢我需要把它变成一个环境变量还是什么？如前所述，我对postman是新手……但变量是否总是默认返回索引[1]，因为它会重新运行每次迭代？我需要使用javascript，我不在我的领域内。这个解决方案就像你描述的，把所有的ID放在一个数组中，假设在我下一步调用“emailID”时，我可以指向数组的索引，然后增加该索引以在每个电子邮件中移动？在我看来，该程序将对请求进行100次迭代，每次选择下一个电子邮件ID，并根据下一个get请求中的一组值进行检查。假设对整个列表执行get请求更容易，然后迭代该数组？@Josh请求的有趣之处在哪里？它正在对响应进行迭代。发送请求，获取响应，将响应中的所有电子邮件ID存储到数组中。现在你做你想做的事情ids@Josh添加了完整的解决方案，现在我们只发送第一个请求一次，第二个请求100次，每次发送一封电子邮件\u id值非常感谢。这正是我想要做的。现在，这允许电子邮件ID增加，然后存储在ID变量中。我想让我感到不舒服的是请求前的部分，我一直在测试它，忘记了在请求之前运行的部分。我将学习一些Javascript技能，因为我在这方面缺乏。巨大的帮助。
let jsonData = pm.response.json();
let temp = []
jsonData.messages.forEach((b)=>{
    temp.push(b.id)
})

pm.environment.set("emailID",temp)

console.log(pm.environment.get("emailID"))

let emailIDList = pm.environment.get("emailID");


pm.environment.set("id", emailIDList.pop())
pm.environment.set("emailID", emailIDList)
if (emailIDList.length > 0) {
    postman.setNextRequest("get Message with id")
}
