Question

当我们查询[翻译API] [1]：

function curl($url, $post_array=false){ 
        $handle = curl_init();
        if (FALSE === $handle) 
            throw new Exception('failed to CURL initialize; '. __FILE__);
        curl_setopt($handle, CURLOPT_URL, $url);
        curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
        if($post_array) {
            curl_setopt($handle, CURLOPT_POST, 1 );
            curl_setopt($handle, CURLOPT_POSTFIELDS, $post_array );
        } 
        curl_setopt($handle,CURLOPT_HTTPHEADER,array('X-HTTP-Method-Override: GET'));
        $response = curl_exec($handle);
        return $response;
}


var_dump ( curl("https://www.googleapis.com/language/translate/v2", ['key'=>$key, 'q[]'=>"hello", 'q[]'=>"world", 'source'=>"en", 'target'=>'ru']   ) );

错误结束：

{
  "error": {
    "code": 400,
    "message": "Required Text",
    "errors": [
      {
        "message": "Required Text",
        "domain": "global",
        "reason": "required"
      }
    ]
  }
}

如何发送多个q输入文本？如我所见，该API不允许使用q[]类型的数组，而是使用多个q参数。但是在php中，数组中不能多次具有相同的键...

Answer 1

我相信此API支持JSON，并且JSON支持数组，所以只需

post-id

并称呼它

function curl($url, array $post_array){ 
        $handle = curl_init();
        curl_setopt_array($ch,array(
CURLOPT_POST=>1,
CURLOPT_POSTFIELDS=>json_encode($post_data),
CURLOPT_HTTPHEADER=>array('Content-Type: application/json')
));
(...)
}

Answer 2

您应该对发布字段进行编码。 PHP提供了chars = {"@": ["A", "B", "C", "1"], "&": ["D", "E", "F", "2"]} sample_list = ['1', '0', 'b', 'B', '2', '6', 'a', '7', '9', '5', 'c', 'd', '4', 'A', 'C', 'f', 'D', 'F', '3', 'C', '8', 'A', 'F', 'B', 'A', 'A', 'D'] for k, v in chars.items(): for value in v: if value in sample_list: ind = [index for index, val in enumerate(sample_list) if val == value] for x in ind: sample_list[x] = k print(sample_list)。

http_build_query

相关的是this post和this post。

正如评论中所建议的那样，您可以为POST数据提供一个字符串，而不是使用在POSTFIELDS数据数组（或PHP中的任何数组）中不能有重复键的数组。

我的卷曲功能

function curl( $url=NULL, $options=NULL ){
    $cacert='c:/wwwroot/cacert.pem';    #<---- edit to suit
    $vbh = fopen('php://temp', 'w+');


    $res=array(
        'response'  =>  NULL,
        'info'      =>  array( 'http_code' => 100 ),
        'headers'   =>  NULL,
        'errors'    =>  NULL
    );
    if( is_null( $url ) ) return (object)$res;

    session_write_close();

    /* Initialise curl request object */
    $curl=curl_init();
    if( parse_url( $url,PHP_URL_SCHEME )=='https' ){
        curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, true );
        curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, 2 );
        curl_setopt( $curl, CURLOPT_CAINFO, $cacert );
    }

    /* Define standard options */
    curl_setopt( $curl, CURLOPT_URL,trim( $url ) );
    curl_setopt( $curl, CURLOPT_AUTOREFERER, true );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, true );
    curl_setopt( $curl, CURLOPT_FAILONERROR, true );
    curl_setopt( $curl, CURLOPT_HEADER, false );
    curl_setopt( $curl, CURLINFO_HEADER_OUT, false );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $curl, CURLOPT_BINARYTRANSFER, true );
    curl_setopt( $curl, CURLOPT_CONNECTTIMEOUT, 20 );
    curl_setopt( $curl, CURLOPT_TIMEOUT, 60 );
    curl_setopt( $curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36' );
    curl_setopt( $curl, CURLOPT_MAXREDIRS, 10 );
    curl_setopt( $curl, CURLOPT_ENCODING, '' );

    curl_setopt( $curl, CURLOPT_VERBOSE, true );
    curl_setopt( $curl, CURLOPT_NOPROGRESS, true );
    curl_setopt( $curl, CURLOPT_STDERR, $vbh );



    /* Assign runtime parameters as options */
    if( isset( $options ) && is_array( $options ) ){
        foreach( $options as $param => $value ) curl_setopt( $curl, $param, $value );
    }

    /* Execute the request and store responses */
    $res=(object)array(
        'response'  =>  curl_exec( $curl ),
        'info'      =>  (object)curl_getinfo( $curl ),
        'errors'    =>  curl_error( $curl )
    );
    rewind( $vbh );
    $res->verbose=stream_get_contents( $vbh );
    fclose( $vbh );
    curl_close( $curl );
    return $res;
}

请求的配置：

$key='AIzaSyxxxxxxxxxxxxxxxxxxx9oIhY8Q8xxxxx';

$url='https://www.googleapis.com/language/translate/v2';
$arr=array( 'another', 'elephant', 'banana', 'woman' );

/* some translate parameters */
$params=array(
    'target'    =>  'fr',
    'format'    =>  'text',
    'source'    =>  'en',
    'model'     =>  'nmt'
);
/* the POST data */
$query=implode( '&', array( 
    sprintf( 'key=%s&q=%s',$key, implode( '&q=', $arr ) ), #query
    urldecode( http_build_query( $params ) ) #google params
));

$config=array(
    CURLOPT_POST        =>  true,
    CURLOPT_POSTFIELDS  =>  $query
);

$res=curl( $url, $config );
if( $res->info->http_code==200 ){
    printf('<pre>%s</pre>',print_r( $res->response,true ) );
}

似乎可以正常工作并返回：

{
  "data": {
    "translations": [
      {
        "translatedText": "un autre",
        "model": "nmt"
      },
      {
        "translatedText": "l'éléphant",
        "model": "nmt"
      },
      {
        "translatedText": "banane",
        "model": "nmt"
      },
      {
        "translatedText": "femme",
        "model": "nmt"
      }
    ]
  }
}
