200分求助CURL设置HTTPHEADER上传文件问题!

Jun 23, 2016 pm 02:20 PM

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

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); 

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_ENCO……

貌似没看到使用了CURLOPT_HTTPHEADER

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;
登录后复制

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;
登录后复制

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
