Curl 在谷歌硬盘上传请求中使用可恢复选项

我想上传一个独立于大小的文件。我使用“可恢复”选项。下面的代码适用于文本文件，但当我使用pdf文件或其他扩展名（jpg，7z）时，总是会出现503错误。此外，如果我想通过区块发送，我会收到代码308。 此外，是否可以将用户元数据添加为“key=value”

---

我发现pdf文件有问题。事实上，我通过文件大小更改了strlen（buffer）以获取信息，如果添加“curl_easy_setopt（curl，CURLOPT_HTTPHEADER，headerList）；”就可以了，所以对于最后一个块，我收到了200 OK

// Get Buffer
pInputName = fopen (FILE_PATH,"rb");
if (pInputName==NULL) {
    perror ("Error opening file");
    return (-1);
}
else
{
    resultat = fseek(pInputName, 0, SEEK_END);
    filesize= (size_t) ftell(pInputName);
    rewind(pInputName);
    buffer = (char *) calloc(filesize+1, sizeof(char));
    resultat = fread (buffer,sizeof(char),filesize,pInputName);
    fclose (pInputName);
}
