  - onBeforeURLRequest
```
public void onBeforeURLRequest(BeforeURLRequestParams params)
```
    Description copied from interface: NetworkDelegate
    
    This method is invoked when a request is about to occur. This event is sent before any TCP connection is made and can be used to redirect requests to another location. This method is invoked synchronously. URL request will be blocked while this method is executing. If this method throws an exception, then default behavior will be used - the target URL will not be changed.
    当即将发生请求时，将调用此方法。在建立任何TCP连接之前发送此事件，该事件可用于将请求重定向到另一个位置。该方法被同步调用。执行此方法时，URL请求将被阻止。如果此方法引发异常，则将使用默认行为-目标URL将不会更改。
    
    Specified by:
    
    onBeforeURLRequest in interface NetworkDelegate
    
    Parameters:
    
    params - provides information about request URL and HTTP method ("GET", "POST", etc.). To override the target URL use the RequestParams.setURL(String) method. -提供有关请求URL和HTTP方法的信息（“ GET”，“ POST”等）。要覆盖目标URL，请使用方法。
  - onBeforeRedirect
```
public void onBeforeRedirect(BeforeRedirectParams params)
```
    Description copied from interface: NetworkDelegate
    
    This method is invoked when a server-initiated redirect is about to occur. This method is invoked synchronously. URL request will be blocked while this method is executing. If this method throws an exception, the loading process will not be affected.
    当服务器启动的重定向即将发生时，将调用此方法。该方法被同步调用。执行此方法时，URL请求将被阻止。如果此方法引发异常，则加载过程将不受影响。
    
    Specified by:
    
    onBeforeRedirect in interface NetworkDelegate
    
    Parameters:
    
    params - provides information about the current URL, new URL, HTTP method ("GET", "POST", etc.) and HTTP response code (e.g., 200, 404, and so on). -提供有关当前URL，新URL，HTTP方法（“ GET”，“ POST”等）和HTTP响应代码（例如200、404等）的信息。
  - onBeforeSendHeaders
```
public void onBeforeSendHeaders(BeforeSendHeadersParams params)
```
    Description copied from interface: NetworkDelegate
    This method is invoked when a request is about to occur and the initial headers have been prepared. It allows adding, modifying, and deleting HTTP request headers. This method is invoked synchronously. URL request will be blocked while this method is executing. If this method throws an exception, the loading process will not be affected.
    Note that one URL request can be split into several HTTP requests (for example to fetch individual byte ranges from a large file) or can be handled by the network stack without communicating with the network. For this reason, the event does not provide the final HTTP headers that are sent to the network. For example, all headers that are related to caching are invisible.
    
    The following headers are currently not provided to the onBeforeSendHeaders event.
    - Authorization
    - Cache-Control
    - Connection
    - Content-Length
    - Host
    - If-Modified-Since
    - If-None-Match
    - If-Range
    - Partial-Data
    - Pragma
    - Proxy-Authorization
    - Proxy-Connection
    - Transfer-Encoding
    当即将发生请求并且已经准备好初始标头时，将调用此方法。它允许添加，修改和删除HTTP请求标头。该方法被同步调用。执行此方法时，URL请求将被阻止。如果此方法引发异常，则加载过程将不受影响。请注意，一个URL请求可以分为几个HTTP请求（例如，从一个大文件中提取单个字节范围），或者可以由网络堆栈处理而无需与网络进行通信。因此，该事件不提供发送到网络的最终HTTP标头。例如，所有与缓存相关的标头都是不可见的。当前未向onBeforeSendHeaders事件提供以下标头。授权缓存控制连接内容长度主机If-Modified-If-None-Match-If-Range部分数据语法Proxy-授权Proxy-Connection传输编码
    
    Specified by:
    
    onBeforeSendHeaders in interface NetworkDelegate
    
    Parameters:
    
    params - provides information about request URL, HTTP method ("GET", "POST", etc.) and HTTP request headers. -提供有关请求URL，HTTP方法（“ GET”，“ POST”等）和HTTP请求标头的信息。
  - onSendHeaders
```
public void onSendHeaders(SendHeadersParams params)
```
    Description copied from interface: NetworkDelegate
    
    This method is invoked right before the HTTP headers are sent to the network. This event is informational and it does not allow modifying HTTP headers. This method is invoked synchronously. URL request will be blocked while this method is executing. If this method throws an exception, the loading process will not be affected.
    在HTTP标头发送到网络之前，将立即调用此方法。此事件是信息性事件，它不允许修改HTTP标头。该方法被同步调用。执行此方法时，URL请求将被阻止。如果此方法引发异常，则加载过程将不受影响。
    
    Specified by:
    
    onSendHeaders in interface NetworkDelegate
    
    Parameters:
    
    params - provides information about request URL, HTTP method ("GET", "POST", etc.) and HTTP request headers. HTTP headers overriding has no effect. -提供有关请求URL，HTTP方法（“ GET”，“ POST”等）和HTTP请求标头的信息。 HTTP标头覆盖无效。
  - onHeadersReceived
```
public void onHeadersReceived(HeadersReceivedParams params)
```
    Description copied from interface: NetworkDelegate
    
    This method is invoked each time that an HTTP(S) response header is received. Due to redirects and authentication requests this can happen multiple times per request. This event is intended to allow adding, modifying, and deleting HTTP response headers, such as incoming "Set-Cookie" headers.
    This method is invoked synchronously. URL request will be blocked while this method is executing. If this method throws an exception, the loading process will not be affected.
    
    每当接收到HTTP（S）响应标头时，都会调用此方法。由于重定向和身份验证请求，每个请求可能会多次发生。此事件旨在允许添加，修改和删除HTTP响应标头，例如传入的“ Set-Cookie”标头。该方法被同步调用。执行此方法时，URL请求将被阻止。如果此方法引发异常，则加载过程将不受影响。
    
    Specified by:
    
    onHeadersReceived in interface NetworkDelegate
    
    Parameters:
    
    params - provides information about request URL, HTTP method ("GET", "POST", etc.) and HTTP request headers. -提供有关请求URL，HTTP方法（“ GET”，“ POST”等）和HTTP请求标头的信息。
  - onResponseStarted
```
public void onResponseStarted(ResponseStartedParams params)
```
    Description copied from interface: NetworkDelegate
    
    This method is invoked when the first byte of the response body is received. For HTTP requests, this means that the status line and response headers are available. This event is informational.
    This method is invoked synchronously. URL request will be blocked while this method is executing. If this method throws an exception, the loading process will not be affected.
    
    当接收到响应主体的第一个字节时，将调用此方法。对于HTTP请求，这意味着状态行和响应标头均可用。此事件是信息性的。该方法被同步调用。执行此方法时，URL请求将被阻止。如果此方法引发异常，则加载过程将不受影响。
    
    Specified by:
    
    onResponseStarted in interface NetworkDelegate
    
    Parameters:
    
    params - provides information about request URL, HTTP method ("GET", "POST", etc.) and HTTP response code. -提供有关请求URL，HTTP方法（“ GET”，“ POST”等）和HTTP响应代码的信息。
  - onDataReceived
```
public void onDataReceived(DataReceivedParams params)
```
    Description copied from interface: NetworkDelegate
    
    This method is invoked each time when a part of the response body is received. When the whole response body is received, NetworkDelegate.onCompleted(RequestCompletedParams) method will be fired. This event is informational.
    Note that Mime-Type and Charset, provided by DataReceivedParams, are taken from response headers and may be overridden by NetworkDelegate.onHeadersReceived(HeadersReceivedParams) method.
    
    每当接收到响应主体的一部分时，都会调用此方法。收到整个响应正文后，将触发NetworkDelegate.onCompleted（RequestCompletedParams）方法。此事件是信息性的。请注意，由DataReceivedParams提供的Mime-Type和Charset是从响应头中获取的，并且可以被NetworkDelegate.onHeadersReceived（HeadersReceivedParams）方法覆盖。
    
    Specified by:
    
    onDataReceived in interface NetworkDelegate
    
    Parameters:
    
    params - provides information about request URL, HTTP method ("GET", "POST", etc.), Mime-Type, and response data. -提供有关请求URL，HTTP方法（“ GET”，“ POST”等），Mime-Type和响应数据的信息。
  - onCompleted
```
public void onCompleted(RequestCompletedParams params)
```
    Description copied from interface: NetworkDelegate
    
    This method is invoked when a request has been processed successfully or failed. You can get information about HTTP request status via the RequestCompletedParams.getStatus() method. If HTTP request status is RequestStatus.FAILED, you can get information about network error using the RequestCompletedParams.getErrorCode() method.
    请求成功或失败处理后，将调用此方法。您可以通过RequestCompletedParams.getStatus（）方法获取有关HTTP请求状态的信息。如果HTTP请求状态为RequestStatus.FAILED，则可以使用RequestCompletedParams.getErrorCode（）方法获取有关网络错误的信息。
