Using curl to upload POST data with files
我想使用curl不仅在HTTP Post中发送数据参数,而且上传具有特定表单名称的文件。我该怎么做呢?
HTTP POST参数:
用户ID=12345filecomment=这是图像文件
HTTP文件上载:文件位置=/home/user1/desktop/test.jpgfile=image的表单名称(对应于php端的$_files['image']
我计算了curl命令的一部分,如下所示:
1 | curl -d"userid=1&filecomment=This is an image file" --data-binary @"/home/user1/Desktop/test.jpg" localhost/uploader.php |
我遇到的问题是:
1 | Notice: Undefined index: image in /var/www/uploader.php |
号
问题是我正在使用$_files['image']来获取PHP脚本中的文件。
如何相应地调整卷曲命令?
您需要使用
试试这个:
1 2 3 4 5 | curl \ -F"userid=1" \ -F"filecomment=This is an image file" \ -F"image=@/home/user1/Desktop/test.jpg" \ localhost/uploader.php |
将用户ID捕获为路径变量(推荐):
1 2 | curl -i -X POST -H"Content-Type: multipart/form-data" -F"[email protected]" http://mysuperserver/media/1234/upload/ |
。
将用户ID作为表单的一部分捕获:
1 2 | curl -i -X POST -H"Content-Type: multipart/form-data" -F"[email protected];userid=1234" http://mysuperserver/media/upload/ |
或:
1 2 | curl -i -X POST -H"Content-Type: multipart/form-data" -F"[email protected]" -F"userid=1234" http://mysuperserver/media/upload/ |
。
这是我的解决方案,我已经读了很多帖子,它们真的很有用。最后,我为小文件编写了一些代码,使用curl和php,我认为这非常有用。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 | public function postFile() { $file_url ="test.txt"; //here is the file route, in this case is on same directory but you can set URL too like"http://examplewebsite.com/test.txt" $eol =" "; //default line-break for mime type $BOUNDARY = md5(time()); //random boundaryid, is a separator for each param on my post curl function $BODY=""; //init my curl body $BODY.= '--'.$BOUNDARY. $eol; //start param header $BODY .= 'Content-Disposition: form-data; name="sometext"' . $eol . $eol; // last Content with 2 $eol, in this case is only 1 content. $BODY .="Some Data" . $eol;//param data in this case is a simple post data and 1 $eol for the end of the data $BODY.= '--'.$BOUNDARY. $eol; // start 2nd param, $BODY.= 'Content-Disposition: form-data; name="somefile"; filename="test.txt"'. $eol ; //first Content data for post file, remember you only put 1 when you are going to add more Contents, and 2 on the last, to close the Content Instance $BODY.= 'Content-Type: application/octet-stream' . $eol; //Same before row $BODY.= 'Content-Transfer-Encoding: base64' . $eol . $eol; // we put the last Content and 2 $eol, $BODY.= chunk_split(base64_encode(file_get_contents($file_url))) . $eol; // we write the Base64 File Content and the $eol to finish the data, $BODY.= '--'.$BOUNDARY .'--' . $eol. $eol; // we close the param and the post width"--" and 2 $eol at the end of our boundary header. $ch = curl_init(); //init curl curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'X_PARAM_TOKEN : 71e2cb8b-42b7-4bf0-b2e8-53fbd2f578f9' //custom header for my api validation you can get it from $_SERVER["HTTP_X_PARAM_TOKEN"] variable ,"Content-Type: multipart/form-data; boundary=".$BOUNDARY) //setting our mime type for make it work on $_FILE variable ); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/1.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0'); //setting our user agent curl_setopt($ch, CURLOPT_URL,"api.endpoint.post"); //setting our api post url curl_setopt($ch, CURLOPT_COOKIEJAR, $BOUNDARY.'.txt'); //saving cookies just in case we want curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); // call return content curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); navigate the endpoint curl_setopt($ch, CURLOPT_POST, true); //set as post curl_setopt($ch, CURLOPT_POSTFIELDS, $BODY); // set our $BODY $response = curl_exec($ch); // start curl navigation print_r($response); //print response } |

有了这个,我们应该在"api.endpoint.post"上发布以下var。您可以很容易地使用这个脚本进行测试,并且应该在最后一行的函数
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | print_r($response); //print response public function getPostFile() { echo" _SERVER "; echo"[cc]"; print_r($_SERVER['HTTP_X_PARAM_TOKEN']); echo"/[cc]"; echo"_POST "; echo"[cc]"; print_r($_POST['sometext']); echo"/[cc]"; echo"_FILES "; echo"[cc]"; print_r($_FILEST['somefile']); echo"/[cc]"; } |
它应该很好地工作,它们可能是更好的解决方案,但这确实有效,对于理解边界和multipart/from-data-mime如何在PHP和curl库上工作非常有帮助。
如果要上载二进制文件(如csv),请使用以下格式上载文件
1 2 3 4 5 | curl -X POST \ 'http://localhost:8080/workers' \ -H 'authorization: eyJhbGciOiJIUzI1NiIsInR5cCI6ImFjY2VzcyIsInR5cGUiOiJhY2Nlc3MifQ.eyJ1c2VySWQiOjEsImFjY291bnRJZCI6MSwiaWF0IjoxNTExMzMwMzg5LCJleHAiOjE1MTM5MjIzODksImF1ZCI6Imh0dHBzOi8veW91cmRvbWFpbi5jb20iLCJpc3MiOiJmZWF0aGVycyIsInN1YiI6ImFub255bW91cyJ9.HWk7qJ0uK6SEi8qSeeB6-TGslDlZOTpG51U6kVi8nYc' \ -H 'content-type: application/x-www-form-urlencoded' \ --data-binary '@/home/limitless/Downloads/iRoute Masters - Workers.csv' |

然后,运行:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | http -f POST http://localhost:4040/api/users username=johnsnow photo@images/avatar.jpg HTTP/1.1 200 OK Access-Control-Expose-Headers: X-Frontend Cache-control: no-store Connection: keep-alive Content-Encoding: gzip Content-Length: 89 Content-Type: text/html; charset=windows-1251 Date: Tue, 26 Jun 2018 11:11:55 GMT Pragma: no-cache Server: Apache Vary: Accept-Encoding X-Frontend: front623311 ... |
