http_client的chunked传输的一点bug

[Mr.Chen]

cinatra/include/cinatra/http_client.hpp

Lines 893 to 898 in b9f99b5

   read_buf_.consume(length + CRCF.size()); 
   read_chunk_head(keep_alive); 
 } else { 
   callback({}, 200, chunked_result_); 
   clear_chunk_buffer(); 
   do_read(); 

else下面应该加上read_buf_.consume(CRCF.size())。消耗掉crlf，不然如果两个请求共用一个连接会出现协议解析错误。

稍后提一个pr修复下。

还有一处重复代码：

cinatra/include/cinatra/http_client.hpp

Lines 383 to 394 in b9f99b5

 if (size > 0) { 
   char buffer[20]; 
   auto p = i64toa_jeaiii(size, buffer); 
   add_header("cinatra_start_pos", std::string(buffer, p - buffer)); 
 } else { 
   int64_t file_size = fs::file_size(dest_file, code); 
   if (!code && file_size > 0) { 
     char buffer[20]; 
     auto p = i64toa_jeaiii(file_size, buffer); 
     add_header("cinatra_start_pos", std::string(buffer, p - buffer)); 
   } 
 } 

cinatra/include/cinatra/http_client.hpp

Lines 406 to 417 in b9f99b5

 if (size > 0) { 
   char buffer[20]; 
   auto p = i64toa_jeaiii(size, buffer); 
   add_header("cinatra_start_pos", std::string(buffer, p - buffer)); 
 } else { 
   int64_t file_size = fs::file_size(dest_file, code); 
   if (!code && file_size > 0) { 
     char buffer[20]; 
     auto p = i64toa_jeaiii(file_size, buffer); 
     add_header("cinatra_start_pos", std::string(buffer, p - buffer)); 
   } 
 }
