Question

$data是包含json字符串{"clientId":"MyClientID","clientSecret":"MyClientSecret","script":"<?php\n echo \"Welcome to GLB Coding Club\";\n?>\n","stdin":"","language":"php","versionIndex":"2"}的变量。

如下面第一行所示。我已使用json_encode()

将数组编码为json

$data = json_encode(array("clientId"=>"MyClientID","clientSecret"=>"MyClientSecret","script"=> $this->input->post("script",true),"stdin"=>$this->input->post("stdin",true),"language"=>$this->input->post("language",true),"versionIndex"=>$this->input->post("versionIndex",true)));

        $curl = curl_init();
        curl_setopt_array($curl, array(
            CURLOPT_URL => "https://api.jdoodle.com/v1/execute",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => "",
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => "POST",
            CURLOPT_POSTFIELDS => $data,
            CURLOPT_HTTPHEADER => array("cache-control: no-cache","content-type: application/json"),
            CURLOPT_SSL_VERIFYPEER => false
        ));

        $response = curl_exec($curl);
        $err = curl_error($curl);
        curl_close($curl);

        if ($err) {
            echo "cURL Error #:" . $err;
        } 
        else {
            echo $response;
        }

jdoodle没有返回正确的$response，而是返回了要执行的语句。但是，如果我在$data处将{"clientId":"MyClientID","clientSecret":"MyClientSecret","script":"<?php\n echo \"Welcome to GLB Coding Club\";\n?>\n","stdin":"","language":"php","versionIndex":"2"}替换为实际的json字符串CURLOPT_POSTFIELDS => $data，则jdoodle返回正确的$response。

Answer 1

然后，简单地

json_encode(array("clientId"=>"MyClientID","clientSecret"=>"MyClientSecret","script"=> $this->input->post("script",true),"stdin"=>$this->input->post("stdin",true),"language"=>$this->input->post("language",true),"versionIndex"=>$this->input->post("versionIndex",true)))

没有产生您期望的$data字符串，并且给出了正确的响应：

'{"clientId":"MyClientID","clientSecret":"MyClientSecret","script":"<?php\n echo \"Welcome to GLB Coding Club\";\n?>\n","stdin":"","language":"php","versionIndex":"2"}'

只是

echo $data;
exit(0);

在第一行之后，检查形成$data字符串时出了什么问题

Answer 2

我只是将$this->input->post("script",true)修改为html_entity_decode($this->input->post("script",true))。

当通过变量传递json数据时，CURL没有返回正确的响应
