React native react native 0.53.3的Json解析问题

我在react本机api调用中得到了无效的json字符串。这在一段时间内使用了无效的json并返回null。如果有人能解决这个问题，请告诉我

/node\u modules/react native/Libraries/Network/XMLHttpRequest.js

如果json格式不正确，解析器将失败。发布_响应对象以便检查JSON是否从服务器api有效。在ios应用程序中有时会发生这种情况。有时它会起作用。不知道这有什么问题您需要将json记录到另一个日志以检查问题所在，因为服务器序列化响应总是正确的或抛出错误。也许你的api返回了一个空值，但不知何故它无法序列化它。如果看不到响应，就不可能识别出什么是错误的no@NitinSingh我已经检查了api，它正在返回有效的json字符串。这是应用程序的问题。它可能和服务器的响应速度有关，请检查您是否正在等待服务器的响应。（异步和等待或承诺，我的意思是…）

case 'json':
        try {
          this._cachedResponse = JSON.parse(this._response);
        } catch (_) {
          this._cachedResponse = null;
        }
        break;
