200分求助CURL设置HTTPHEADER上传文件问题！

哪位大侠有使用CURL设置HTTPHEADER来上传文件的经验？

求指点

PS：不是 '@'.文件名，而是Content-Type: application/octet-stream

回复讨论(解决方案)

curl不支持这种方式，你需要自己构造数据包。我研究过

curl不支持这种方式，你需要自己构造数据包。我研究过

是否有示例？

http://cn.php.net/fsockopen
CTRL + F搜索boundary，例子好好看看，构建一个文件上传的http请求头即可，按理说CURL构建同样的请求头应该也没问题。

总结一下项目中用到curl的几种方式
1. php curl的默认调用方法，get方式访问url
Java代码
....
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);    //设置http头
    curl_setopt($ch, CURLOPT_ENCODING, "gzip" );         //设置为客户端支持gzip压缩
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30 );  //设置连接等待时间
    curl_setopt($ch, CURLOPT_URL, $url );
    curl_exec( $ch );
    if ($error = curl_error($ch) ) {
        //出错处理
        return -1;
    }
    fclose($fp);

    $curl_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);        //获取http返回值
    if( $curl_code == 200 ) {
        //正常访问url
    }
    //异常
....

....
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);    //设置http头
    curl_setopt($ch, CURLOPT_ENCODING, "gzip" );         //设置为客户端支持gzip压缩
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30 );  //设置连接等待时间
    curl_setopt($ch, CURLOPT_URL, $url );
    curl_exec( $ch );
    if ($error = curl_error($ch) ) {
        //出错处理
        return -1;
    }
    fclose($fp);

    $curl_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);        //获取http返回值
    if( $curl_code == 200 ) {
        //正常访问url
    }
    //异常
....
2. 设置http header支持curl访问lighttpd服务器
Java代码
$header[]= 'Expect:';

$header[]= 'Expect:';
3. 设置curl，只获取http header，不获取body：
Java代码
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);

curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
或者只获取body：
Java代码
curl_setopt($ch, CURLOPT_HEADER, 0);   // make sure we get the body
curl_setopt($ch, CURLOPT_NOBODY, 0);

    curl_setopt($ch, CURLOPT_HEADER, 0);   // make sure we get the body
    curl_setopt($ch, CURLOPT_NOBODY, 0);
4. 访问虚拟主机，需设置Host
$header[]= 'Host: '.$host;
5. 使用post, put, delete等REStful方式访问url
post:
    curl_setopt($ch, CURLOPT_POST, 1 );
put, delete:
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");  //或者PUT，需要服务器支持这些方法。
6. 保存下载内容为文件
    curl_setopt($ch, CURLOPT_FILE, $fp);

http://cn.php.net/fsockopen
CTRL + F搜索boundary，例子好好看看，构建一个文件上传的http请求头即可，按理说CURL构建同样的请求头应该也没问题。

谢谢，CURL不支持这种上传方法吗？

可能是比较复杂吧，所以 curl 提供了 '@'.文件名的方式。把构造头和数据的工作留给了自己

但 curl 依然提供了 CURLOPT_UPLOAD 来表示上传文件，但实际上使用了 PUT 请求
只适合向 ftp 上传文件
在 php 中，要从 php://input 读取

使用 #5 给出的代码，会产生无法识别的请求这样的错误，注释掉文件上传的那段，依然报这个错。不知是什么原因
但对比 curl PUT 方式的数据报，似乎也没有什么差异

知道了，这样写就可以！

$contents =<<< 'TEXT'数据报中应该是Content-Disposition: form-data; name="userfile"; filename="file_name"Content-Type: 文档类型文件内容这样的格式，我只实现了文件名部分，文档类型不知道如何实现。这样上传后就取不到 type 的值curl_upload_server.php<xmp><?phpprint_r($_FILES);echo "文件内容:\n";$p = current($_FILES);readfile($p['tmp_name']);TEXT;$fields['f"; filename="x.x'] = $contents; //这个关联键的写法很怪异吧？$ch = curl_init();  curl_setopt($ch, CURLOPT_URL,"http://localhost/curl_upload_server.php");  curl_setopt($ch, CURLOPT_POST, 1 );curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$s = curl_exec ($ch);  curl_close ($ch);  echo $s;

Copy after login

原来这样就有 type了

$varname = 'my';$name = '3.txt';$type = 'text/plain';$key = <<< TEXT$varname"; filename="$nameContent-Type: $typeTEXT;$fields[$key] = $contents;

Copy after login

注意：我是在 win 下的，linux 下要将 \n 换成 \r\n
没办法，早年的 sun 是拼不过 ms 的，现在也不行吧？

一直以为上传的文件类型是 php 识别的，却原来是浏览器提供的

原来这样就有 type了PHP code
$varname = 'my';
$name = '3.txt';
$type = 'text/plain';
$key = <<< TEXT
$varname"; filename="$name
Content-Type: $type

TEXT;
$fields[$key] = $contents;

注意：我是在 win 下的，linux 下……

很感谢，有没有比较完整的CURL 通过拼接HTTPHEADER信息上传的POST示例呢？

#10 就是
curl_upload_server.php 就是测试用服务器端

JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5.

Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5.
