所以,我试图在我的Laravel 5.3中运行一个python脚本。
这个功能在我的控制器里。这只是将数据传递给我的python脚本
public function imageSearch(Request $request) {
$queryImage = 'c:\\\xampp\\\htdocs\\\identificare_api\\\public\\\gallery\\\herbs\\\query.png'; //queryImage
$trainImage = 'c:\\\xampp\\\htdocs\\\identificare_api\\\public\\\gallery\\\herbs\\\2nd.png'; //trainImage
$trainImage1 = 'c:\\\xampp\\\htdocs\\\identificare_api\\\public\\\gallery\\\herbs\\\3rd.png';
$trainImage2 = 'c:\\\xampp\\\htdocs\\\identificare_api\\\public\\\gallery\\\herbs\\\4th.jpg';
$trainImage3 = 'c:\\\xampp\\\htdocs\\\identificare_api\\\public\\\gallery\\\herbs\\\1st.jpg';
$data = array
(
array(0, $queryImage),
array(1, $trainImage),
array(3, $trainImage1),
array(5, $trainImage2),
array(7, $trainImage3),
);
$count= count($data);
$a = 1;
$string = "";
foreach( $data as $d){
$string .= $d[0] . '-' . $d[1];
if($a < $count){
$string .= ",";
}
$a++;
}
$result = shell_exec("C:\Python27\python c:\xampp\htdocs\identificare_api\app\http\controllers\ORB\orb.py " . escapeshellarg($string));
echo $result;
}
我的python脚本是一个ORB算法,它在将火车图像与查询图像进行比较后返回最小的距离及其id。这是我的python脚本:
import cv2
import sys
import json
from matplotlib import pyplot as plt
arrayString = sys.argv[1].split(",")
final = []
for i in range(len(arrayString)):
final.append(arrayString[i].split("-"))
img1 = cv2.imread(final[0][1], 0)
for i in range(1, len(arrayString)):
img2 = cv2.imread(final[i][1], 0)
# Initiate STAR detector
orb = cv2.ORB_create()
# find the keypoints and descriptors with SIFT
kp1, des1 = orb.detectAndCompute(img1,None)
kp2, des2 = orb.detectAndCompute(img2,None)
# create BFMatcher object
bf = cv2.BFMatcher(cv2.NORM_HAMMING, crossCheck=True)
# Match descriptors.
matches = bf.match(des1,des2)
# Sort them in the order of their distance.
matches = sorted(matches, key = lambda x:x.distance)
# Draw first 10 matches.
img3 = cv2.drawMatches(img1,kp1,img2,kp2,matches[:10], None, flags=2)
if i == 1:
distance = matches[0].distance
else:
if distance > matches[0].distance:
distance = matches[0].distance
smallestID = final[i][0]
print str(smallestID) + "-" + json.dumps(distance)
我已经试过在不使用Laravel的情况下运行这两个文件,它运行得很好。但是当我试图将php代码集成到我的Laravel中时,它什么也没有显示。状态代码为200 OK。
编辑:问题已解决。在PHP代码中,只需更改
$result = shell_exec("C:\Python27\python c:\xampp\htdocs\identificare_api\app\http\controllers\ORB\orb.py " . escapeshellarg($string));
到
$result = shell_exec("python " . app_path(). "\http\controllers\ORB\orb.py " . escapeshellarg($string));
那么,你也可以这样做
$queryImage = public_path() . "\gallery\herbs\query.png";
使用Symfony过程会很方便。https://symfony.com/doc/current/components/process.html
确保symphony可用于您的项目
如果未安装,请执行
composer require symfony/process
然后做一些像
对我有效的解决方案是在结尾添加2>;&;1。
我遇到的问题是没有错误,没有回应,我有错误的脚本路径,但没有办法知道。2>;&;1会将调试信息重定向为结果。
In the shell, what does " 2>&1 " mean?
