问题描述

我一直在试图从google的地理编码服务获取json响应。我使用PHP。我试图与fopen，然后我阅读在另一个stackoverflow问题，我应该使用file_get_contents，但没有工作。然后我继续搜索，发现有人在另一个论坛谁说，如果我使用CURL我会更好的解决方案，所以我改变了我的代码，不工作。在所有情况下，我收到了错误400：错误的请求，您的客户发出了错误或非法的请求。

I've been trying to get a json response from google's geocoding service. I'm using PHP. I was trying with fopen, then I read in another stackoverflow question that I should use file_get_contents, but didn't worked too. Then I keep searching and found someone in another forum who said I would a better solution if I use CURL so I changed my code and is not working. In all cases I received an "Error 400: Bad Request. Your client has issued a malformed or illegal request."

我的代码是：

$jsonUrl = "http://maps.googleapis.com/maps/api/geocode/json?address=" . $cityName . "&sensor=false";

    $geocurl = curl_init();
    curl_setopt($geocurl, CURLOPT_URL, $jsonUrl);
    curl_setopt($geocurl, CURLOPT_HEADER,0); //Change this to a 1 to return headers
    curl_setopt($geocurl, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]);
    curl_setopt($geocurl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($geocurl, CURLOPT_RETURNTRANSFER, 1);

    $geofile = curl_exec($geocurl);

然后我打印内容并收到错误消息。

Then I print the content and got the error message.

任何想法？

非常感谢。

推荐答案

好吧，我想出来了。

我的$ cityName变量是：

My $cityName variable was this:

$cityName = "Monterrey, NL";

逗号和NL之间的空格。我使用str_replace为+更改，并获得有效的网址，如文档中所示：

The white space between the comma and "NL". I used str_replace to change " " for "+" and get a valid url like in the documentation:
