有没有人有经验的限制从包？postFormRCurl
我正在从服务器上提取数据，几乎不知从哪里得到了错误消息* HTTP 1.0, assume close after body，然后是500 Internal Server Error. 我测试了配置，一切似乎都很好。我创建了一个干净的数据库并重新上传了我的数据库 20/30 案例，同时使用 API/postForm调用从R. 一切正常，直到我达到大约 150 个案例，然后出现错误消息。无论我上传错误中的案例的顺序如何，都会出现大约 150/160 个案例，总文件大小约为 11 到 12 MB。换句话说，错误似乎并不取决于特定情况，因为破坏它的情况不同
任何意见，将不胜感激。
我附上了一个截图来为这个相当无聊的帖子增添一点趣味，并弥补没有一个有效的例子，

正如哈德利的评论中所建议的那样，我添加了RCurl有效调用和失败调用的详细输出，见下文
适用于数据库中少于 150 个案例的调用
