CURLFORM_FILE: 表示字段值是一个文件,接下来的参数为文件路径。 CURLFORM_CONTENTTYPE: 表示字段值是文件时的 MIME 类型,接下来的参数为 MIME 类型的字符串值。 CURLFORM_BUFFER: 表示字段值是一个缓冲区,接下来的参数为缓冲区指针。 CURLFORM_BUFFERPTR: 缓冲区的指针,接下来的参数为缓冲区指针。 CURLFORM_...
常见的字段类型有以下几种:CURLFORM_COPYCONTENTS、CURLFORM_FILE、CURLFORM_BUFFER等。不同的字段类型对应不同的字段值传递方式。 接下来,我们将对curl_formadd函数的参数进行使用示例,以便更好地理解函数的用法。 我们需要创建一个curl_httppost结构体的指针,用于存储POST请求的表单数据。可以使用curl_formadd函数的...
Prior to 7.56.0, fieldnames and filenames were set in Content-Disposition header without special processing: this may lead to invalid RFC 822 quoted-strings. 7.56.0 introduces escaping of backslashes and double quotes in these names: mention it in the documentation. Reported-by: daboul on githu...
The options from CURLFORM_FILE through CURL-FORM_BUFFERLENGTH are for file upload parts.OPTIONSCURLFORM_COPYNAMEfollowed by a string which provides the name of this part. libcurl copies the string so your applica-tion doesn’t need to keep it around after this function call. If the name ...
CURLFORM_FILENAME is used in combination with CURLFORM_FILE. Followed by a pointer to a string, it tells libcurl to use the given string as the filename in the file upload part instead of the actual file name. CURLFORM_BUFFER is used for custom file upload parts without use of...

But adding CURLFORM_FILENAME was also not succesful. This one is close, but instead of CURLFORM_PTRCONTENTS and CURLFORM_FILENAME, use CURLFORM_BUFFERPTR, CURLFORM_BUFFER and CURLFORM_BUFFERLENGTH. Post by Schäffer Klaus Dan --- List admin: http://cool.haxx.se/list/listinfo/curl-...
在上述示例中,我们通过curl_formadd函数分别添加了名为”field1”和”field2”的两个表单字段,并设置相应的值为”value1”和”value2”。然后,我们使用cURL发送POST请求,并将表单数据传输给指定的URL。最后,我们清理资源并释放表单链表的内存。 请确保在编译时链接了libcurl库,并且包含了curl/curl.h头文件。
