Question

我尝试使用libcurl将文件上传到服务器。主要代码是：

   /* Create the form */
    form = curl_mime_init(curl);

    /* Fill in the file upload field */
    field = curl_mime_addpart(form);
    curl_mime_name(field, "imgfile");
    curl_mime_filedata(field, uploadFilePath);

    // setup mime post form
    curl_easy_setopt(curl, CURLOPT_MIMEPOST, form);

    /* enable verbose for easier tracing */
    curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);

    /* Perform the request, res will get the return code */
    ret = curl_easy_perform(curl);

除非上传文件很大，否则一切正常。当文件很大时，libcurl崩溃，http详细日志为：

我尝试禁用Expect: 100-continue，但没有任何变化。
