json到php（服务器）的可能性以及如何实现？

基本上我想被转移到我的服务器/php

我试试这个

$url="http://maps.google.com/maps/nav?q=from:9500 wil to:3000 bern";
$conte = file_get_contents($url);
echo $conte;

---

json不是echo，如何将输出保存到服务器？

您想如何保存它？作为文件

如果可以通过

file\u get\u contents（）

打开，则打开

fopen（）

wrappers的URL打开

然后你就可以做

$url = 'http://maps.google.com/maps/nav?q=from:9500 wil to:3000 bern';

$content = file_get_contents($url);

file_put_contents('google-map-json.txt', $content);

您可以使用

json\u decode（）

在PHP中将其转换为可用对象

如果要将其保存到数据库中，可能需要执行此操作

如果不希望每次都覆盖该文件，可以为文件名生成响应的随机散列，或者类似的内容

对不起，我的错。我知道如何保存文件。但是json甚至没有通过文件内容得到响应

您可能没有启用URL

fopen（）

wrappers

您可以通过运行此

var_dump(ini_get('allow_url_fopen'));

如果它被禁用，并且您不能或不想打开它，那么可以使用cURL（如果您已经安装了该库）

更新 当我试图通过

file\u get\u contents（）

访问页面时，我得到了

HTTP/1.0 400错误请求

您可能需要使用cURL，并模拟浏览器（用户代理等）

或者你可以设置

ini_set('user_agent', 'Mozilla or something');

然后使用

file\u get\u contents（）

更新 我也试过卷发，但不起作用：(

我认为下一步是检查浏览器发送的所有标题（当它工作时），然后通过cURL发送等效的标题

更新

我注意到Markdown编辑器不喜欢URL（），这让我明白了-

urlencode（）

GET参数！

您可以使用PHP的IO函数将数据写入文件

$fp = fopen('data.txt', 'a');
fwrite($fp, $conte);
fclose($fp);

---

您可以使用解析变量中的数据。（我个人会使用而不是）。

您需要

urlencode

获取参数：

echo file_get_contents('http://maps.google.com/maps/nav?q=from:9500%20wil%20to:3000%20bern');

抱歉，我的不好。我知道如何保存文件。但是json甚至没有通过hostgator上的file_get_contents.im进行回送，所以它可以工作。但是代码不工作，请自己尝试。我不能用php编写或回送输出。我知道如何使用Javascript，但这不是问题。@Email-Hmm，URL回送在我的hostgator帐户上对我有效。What不执行变量转储（文件获取内容（'http://maps.google.com/maps/nav?q=from:9500 威尔斯：3000伯尔尼‘）output？他们是否可能阻止用户代理或您的IP？它在过去工作过吗？上面的更新代码输出是什么？thx 4您的帮助。这确实是jwandborg所说的urlencode。+1文件是空的，因为连数据的回显都失败了。我用

curl-I收到HTTP/1.0 400错误请求"http://maps.google.com/maps/nav?q=from:9500 wil to:3000 bern“

+1.我在编辑OP时就知道了，所以我还是用我的答案发布了它。希望你不要介意。@alex-没问题，我刚开始尝试curl时也在使用fopen URL包装器，但它也不起作用-它必须是参数。
