ngx.req.set_body_data --------------------- **语法:** *ngx.req.set_body_data(data)* **环境:** *rewrite_by_lua*\**, access_by_lua*\**, content_by_lua*\* 使用 `data` 参数指定的内存数据设置当前请求的请求体。 如果当前请求的请求体尚未被读取，它将被安全地丢弃。当请求体已经被读进内存或缓存在磁盘文件中时，相应的内存或磁盘文件将被立即清理回收。 这个函数在 `v0.3.1rc18`` 版本中首次引入。 更多用法请参考 [ngx.req.set_body_file](#ngxreqset_body_file)。 > English Source **syntax:** *ngx.req.set_body_data(data)* **context:** *rewrite_by_lua*\**, access_by_lua*\**, content_by_lua*\* Set the current request's request body using the in-memory data specified by the `data` argument. If the current request's request body has not been read, then it will be properly discarded. When the current request's request body has been read into memory or buffered into a disk file, then the old request body's memory will be freed or the disk file will be cleaned up immediately, respectively. This function was first introduced in the `v0.3.1rc18` release. See also [ngx.req.set_body_file](#ngxreqset_body_file). [返回目录](#nginx-api-for-lua)
