用于通过API向Google地方信息添加新地点的PHP代码

Question

我正在努力将Google的Places API集成到网络应用中.我已经能够成功创建代码以允许用户使用API​​搜索地点并在应用程序中显示结果,这样很酷.

我无法弄清楚的是如何让应用程序的用户添加新的地方.谷歌说的东西是可行的.他们在这里有一些文件 -

https://code.google.com/apis/maps/documentation/places/#adding_a_place

但是没有示例代码,我在编写PHP代码以实现add调用时遇到了一些困难.

---

这是我到目前为止提出的代码.我在这里用{your key}替换了我的实际API密钥.

我一直收到错误的帖子错误 -

那是一个错误.您的客户发出了格式错误或非法的请求.我们知道的就这些.

<?php

function ProcessCurl($URL, $fieldString){ //Initiate Curl request and send back the result
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_HTTPHEADERS, array('Content-Type: application/json'));
        curl_setopt($ch, CURLOPT_URL, $URL);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
        curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
        curl_setopt($ch, CURLOPT_POSTFIELDS, array('json'=>json_encode($fieldString)));
        $resulta = curl_exec ($ch);
        if (curl_errno($ch)) {
                print curl_error($ch);
        } else {
        curl_close($ch);
        }
        echo $resulta;
    }

$jsonpost = '{
  "location": {
    "lat": -33.8669710,
    "lng": 151.1958750
   },
  "accuracy": 50,
   "name": "Daves Test!",
   "types": ["shoe_store"],
  "language": "en-AU"
}';
 $url = "https://maps.googleapis.com/maps/api/place/add/json?sensor=false&key={your key}";

 $results = ProcessCurl ($url, $jsonpost);

 echo $results."<BR>";
?> 

Answer 1

您的代码存在一些问题.

首先,你CURLOPT_HTTPHEADERS实际上是在使用它的时候CURLOPT_HTTPHEADER(没有尾随的"S").该行应为:

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));

接下来,Google不希望您传递参数名称,只是一个值.另一件事是$jsonpost已经是JSON所以没有必要打电话json_encode.该行应为:

curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldString);

有关详情,请查看Google文档:http://code.google.com/apis/maps/documentation/places/#adding_a_place.

您的完整代码,修复,测试和工作:

<?php

function ProcessCurl($URL, $fieldString){ //Initiate Curl request and send back the result
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
        curl_setopt($ch, CURLOPT_URL, $URL);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_VERBOSE, 1);
        //curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldString);
        $resulta = curl_exec ($ch);
        if (curl_errno($ch)) {
                print curl_error($ch);
        } else {
        curl_close($ch);
        }
        echo $resulta;
    }

$jsonpost = '{
  "location": {
    "lat": -33.8669710,
    "lng": 151.1958750
   },
  "accuracy": 50,
   "name": "Daves Test!",
   "types": ["shoe_store"],
  "language": "en-AU"
}';

$url = "https://maps.googleapis.com/maps/api/place/add/json?sensor=false&key=";

$results = ProcessCurl ($url, $jsonpost);

echo $results."<BR>";
