如何使用 .fetch 函数在 react-native 中使 API 调用 IPV6 兼容? [英] How to make API calls IPV6 compatible in react-native using the .fetch function?

问题描述

我开发了一个用 react native 编写的应用程序(用于 IOS)，该应用程序在 IPV4 网络中运行良好.但是，最近 Apple 发送了一条消息，说我的应用程序在 IPV6 网络中测试时无法运行.他们告诉我，我还必须让它与仅限 IPV6 的网络兼容.

I have developed an app (for IOS) written in react native which is working good in IPV4 networks. However, recently Apple has sent a message saying that my app did not work when tested in an IPV6 network. They told me that I had to make it compatible with IPV6-only networks too.

问题是，如何使我现有的 API 调用与 IPV6 网络兼容?

The question is, how can I make my existing API calls compatible with an IPV6 network?

我的 API 使用 https 协议，它是通过域名调用的，而不是原始 IP.

My API uses the https protocol and it is called by domain name, not a raw IP.

我使用的示例 fetch 调用是:

A sample fetch call that I use is:

fetch(query,{
      method: 'post',
      headers: Utils.fetchHeaders('post')
      })
      .then(Utils.checkStatus)
      .then(Utils.parseJSON)
      .then(json => this._handleResponse(json))
      .catch(error => {

         this.setState({
          votingError: 'Sorry, there was an error!',
          loading: false
       });

      });

API 端点采用以下格式:

and the API endpoint is in following format:

推荐答案

fetch API 内部使用 NSURLSession 已经支持 IPv6:

The fetch API internally uses NSURLSession which already supports IPv6:

大多数应用不需要任何更改，因为 NSURLSession 和 CFNetwork API 已经支持 IPv6.

Most apps will not require any changes because IPv6 is already supported by NSURLSession and CFNetwork APIs.

由于您没有在 fetch API 中使用 IPv4 地址，因此您应该可以继续使用.

Since you're not using IPv4 addresses with the fetch API you should be good to go.

所以我怀疑还有其他东西(可能是一些第 3 方代码?)不与此合作.Apple 是否向您提供了有关哪些问题不起作用的更多详细信息?

So I suspect there's something else (maybe some 3rd party code?) not cooperating with this. Did Apple provide you with more details about what was not working?

我建议你关注 本教程 来测试它并找出不正确的地方.
