RequestBuilder.sendRequest介绍

[英]Sends an HTTP request based on the current builder configuration with the specified data and callback. If no request headers have been set, the header "Content-Type" will be used with a value of "text/plain; charset=utf-8". This method does not cache requestData or callback.
[中]使用指定的数据和回调，基于当前生成器配置发送HTTP请求。如果未设置请求头，则头“内容类型”将与值“text/plain；charset=utf-8”一起使用。此方法不缓存requestData或callback。
