我正在写nginx模块,它构造nginx链,然后将此链缓冲区写入nginx临时文件以稍后使用它(刚刚写入后)。我一直在寻找每一个页面,唯一的解决办法拿出的是一个波纹管:如何正确使用ngx_write_chain_to_temp_file?

// Create temp file to test 
      ngx_temp_file_t *tf; 
      tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t)); 
      if (tf == NULL) { 
       return NGX_HTTP_INTERNAL_SERVER_ERROR; 
      } 
      tf->file.fd = NGX_INVALID_FILE; 
      tf->file.log = nlog; 
      tf->path = clcf->client_body_temp_path; 
      tf->pool = r->pool; 
      tf->log_level = r->request_body_file_log_level; 
      tf->persistent = r->request_body_in_persistent_file; 
      tf->clean = r->request_body_in_clean_file; 
      //  if (r->request_body_file_group_access) { 
      //   tf->access = 0660; 
      //  } 
      if (ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access) != NGX_OK) { 
       return NGX_HTTP_INTERNAL_SERVER_ERROR; 
      } 

      if (ngx_write_chain_to_temp_file(tf, bucket->first) == NGX_ERROR) { 
       return NGX_HTTP_INTERNAL_SERVER_ERROR; 
      } 

此代码不会返回NGX_ERROR,那是不是意味着nginx的成功写入临时文件到client_body_temporay_path?答案是肯定的,之后我用fopen打开文件,文件不存在?

任何人都可以请给我正确的解决方案来处理ngx_write_chain_to_temp_file?

,我发现自己的解决方案

 ngx_temp_file_t *tf; 
     tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t)); 
     tf->file.fd = NGX_INVALID_FILE; 
     tf->file.log = nlog; 
     tf->path = clcf->client_body_temp_path; 
     tf->pool = r->pool; 
     tf->persistent = 1; 
     rc = ngx_create_temp_file(&tf->file, tf->path, tf->pool, tf->persistent, tf->clean, tf->access); 
     //ngx_write_chain_to_file(&tf->file, bucket->first, bucket->content_length, r->pool); 
     ngx_write_chain_to_temp_file(tf, bucket->first); 

我无法理解的唯一的事情是,如果我设置tf->persistent为假(0),文件创建之后,我无法从中读出,即使我没有通过对output_filter的响应呢。
