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

问题描述

我已经开发了一个用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，最近苹果公司发送了一条消息，说我的应用程序在IPV6网络中进行测试时无法正常工作.他们告诉我，我也必须使其与仅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，并且通过域名而不是原始IP进行调用.

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

我使用的示例提取调用为:

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
       });

      });

并且API端点的格式如下:

and the API endpoint is in following format:

推荐答案

fetch API内部使用的NSURLSession已经支持IPv6:

The fetch API internally uses NSURLSession which already supports IPv6:

大多数应用将不需要任何更改，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.

由于您未在获取API中使用IPv4地址，因此应该可以使用.

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

因此，我怀疑还有其他问题(也许一些第三方代码?)与此不合作. Apple是否向您提供了有关无法正常工作的更多详细信息?

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?

我建议您遵循本教程在您这边进行测试，找出不正确的地方.

I suggest you follow this tutorial to test it on your side and find out what's incorrect.
