web int类型超出限制后 数据错误

[jiajialaixi]

Package

dio

Version

5.7.0

Operating-System

Web

Adapter

Default Dio

Output of flutter doctor -v

No response

Dart Version

3.5.3

Steps to Reproduce

1、在flutter-web请求接口

Expected Result

Actual Result

在dio获取到的数据与服务器返回的不一致 在android 端这个id 就没有任何问题

我使用flutter http: ^1.2.2 请求接口返回的数据就是正确的

[AlexV525]

与 Dio 无关。

[jiajialaixi]

我的意思并不是获取精度问题 ，服务器返回的数据与dio 断点获取到的数据不一致 而http返回的数据是与服务的数据同步的

提供下最小复现示例，包含同时使用 dio 和 http 的对比。

这个是dio返回数据的第一条id

这个是http返回数据的第一条id

实际上dio断点显示的数据是与response返回的数据不一致的

[AlexV525]

Token 已过期

如果使用 http 进行 jsonDecode(response.body)，精度也会丢失。此问题与 Dio 无关，请自行注意 Web 平台类型限制。
