提取API从响应中获取原始值

本文介绍了提取API从响应中获取原始值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用React-Native请求一些数据，这是我的代码:

I use React-Native request some data, here is my code:

fetch('raw.githubusercontent/facebook/react-native/master/docs/MoviesExample.json') .then((response)=>{ return response.json() }) .then((responseJSON)=>{ callback(responseJSON) }) .catch((error)=>{ console.error(error); }) .done()

我看到response是Response对象，而json功能代码是return this.text().then(JSON.parse)，我很困惑JSON.parse的参数是什么?那是response原始值吗?我怎么能得到它?

I see the response is a Response object, and the json function code is return this.text().then(JSON.parse), I'm confused that what is the parameter of theJSON.parse? Is that the response raw value? How can I get it?

推荐答案

以下是您要执行的操作.就我而言，我想手动解析JSON，因为内置JSON解析器不正确地解析了某个字符(\ u001e).

Here's how you'd do what you want. In my case I wanted to manually parse the JSON because a certain character (\u001e) is improperly parsed by the in-built JSON parser.
