Network Status

axios-sugar对错误的HTTP状态码的默认处理就是简单的打印信息和错误重传。
除此之外，对408超时状态码添加了网络状态的判断和断网重传的功能。

Bulit-in Function

默认情况下，网络检测是关闭的，需要配置一下。

{
  offlineCheck: {
    enable: true
  }
}

Monitoring of network status

import AxiosSugar from 'axios-sugar';

// Triggered when the request is disconnected and reconnected
AxiosSugar.on('online', function (err, retry) {

});

// Connected to the network, but triggered by an unknown cause (not 404, because this is triggered in the 408 processing function)
AxiosSugar.on('onlineTimeout', function (err, retry) {

});

// Disconnection trigger
AxiosSugar.on('offline', function (err) {

});

Automatic retransmission after disconnection

断网自动重传的配置如下：

{
  onlineCheck: {
    enable: true,
    reconnect: {
      enable: true
    }
  },
  retry: {
    enable: true,
    auto: true
  }
}

以上所有的enable字段都是必须为true，auto字段也是自动重传必须的。

Cancel automatic retransmission

Sometimes, it may be necessary to handle some specific errors, such as 4 onlinetimeout, and cancel the automatic retransmission function.

AxiosSugar.on('onlineTimeout', function (err, retry) {
  AxiosSugar.cancelAutoRetry(err);

  console.log('Unknown error causing request timeout!');
});

Custom processing

The above functions are defined in the ontimeout method of the httpstatusprocessor prototype.

If the 408 status code needs to be processed, it can be realized by rewriting this method.

AxiosSugar.httpStatusProcessor.onTimeout = function (
  status, err, result, retry
) {
  const originOnTimeout = AxiosSugar.httpStatusProcessor.prototype.onTimeout;
};

WARNING

If you override onTimeout, you can't use the functions described in this chapter any more.
