# Postman

使用 Postman 可以快速测试[ IPWO 代理](https://www.ipwo.net/)是否正常，适用于 API 调试、接口测试与开发验证场景。

***

### 一、适用场景

适用于：

* API 调试
* 代理测试
* IP 检测
* 开发联调

***

### 二、配置代理

打开：

```
Postman → Settings → Proxy
```

***

### 三、填写代理信息

#### HTTP Proxy

```
Proxy Server:
us.ipwo.net

Port:
7878
```

***

#### Authentication

```
Username:
username_custom_zone_us

Password:
password
```

***

### 四、测试代理是否生效

请求：

```
http://ipinfo.io
```

***

#### 正常返回示例

```json
{
  "ip": "203.0.113.10",
  "country": "US"
}
```

如果返回的 IP：

* 不是本机公网 IP
* 国家地区正确

说明代理已经生效。

***

### 五、常见问题

#### [407 Proxy Authentication Required](/kai-fa-zhe-wen-dang/chang-jian-cuo-wu/407-proxy-authentication-required.md)

通常是：

* 用户名错误
* 密码错误
* zone 参数错误

***

#### [Timeout 超时](/kai-fa-zhe-wen-dang/chang-jian-cuo-wu/chao-shi-timeout.md)

通常是：

* 网络环境异常
* DNS 问题
* 国内网络限制

***

#### IP 未变化

请检查：

* 是否开启 Global Proxy
* 请求是否真正走代理

***

### 六、推荐开发建议

推荐：

* 使用海外网络环境
* 使用住宅代理
* 测试前关闭 VPN 冲突
* 使用 curl 对比测试

***

### 七、推荐排查流程

```
1. 配置代理
↓
2. 请求 ipinfo.io
↓
3. 检查 IP 是否变化
↓
4. 检查报错信息
↓
5. 对比 curl 测试
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ipwo.net/kai-fa-zhe-wen-dang/dai-ma-shi-li/postman.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
