我正在开发一个必须执行Google Places API请求的应用程序。
http://code.google.com/intl/es/apis/maps/documentation/places/
我在以下网站上获得了私钥:
https://code.google.com/apis/console
客户ID:XXXXXXXXXXX.apps.googleusercontent.com
客户机密:YYYYYYYYYYYYYYYYYYY(看起来像vNIXE0xscrmjlyV-12Nj_BvUPaw =)
我正在使用此代码生成网址:
public class UrlSigner {
// Note: Generally, you should store your private key someplace safe
// and read them into your code
private static String keyString = "YYYYYYYYYYYYYYYYYY";
// The URL shown in these examples must be already
// URL-encoded. In practice, you will likely have code
// which assembles your URL from user or web service input
// and plugs those values into its parameters.
private static String urlString = "http://maps.google.com/maps/api/place/search/json?location=40.717859,-73.957790&radius=1600&client=XXXXXXXXXXX.apps.googleusercontent.com&sensor=false";
// This variable stores the binary key, which is computed from the string (Base64) key
private static byte[] key;
public static void main(String[] args) throws IOException,
InvalidKeyException, NoSuchAlgorithmException, URISyntaxException {
// Convert the string to a URL so we can parse it
URL url = new URL(urlString);
UrlSigner signer = new UrlSigner(keyString);
String request = signer.signRequest(url.getPath(),url.getQuery());
System.out.println("Signed URL :" + url.getProtocol() + "://" + url.getHost() + request);
}
public UrlSigner(String keyString) throws IOException {
// Convert the key from 'web safe' base 64 to binary
keyString = keyString.replace('-', '+');
keyString = keyString.replace('_', '/');
System.out.println("Key: " + keyString);
this.key = Base64.decode(keyString);
}
public String signRequest(String path, String query) throws NoSuchAlgorithmException,
InvalidKeyException, UnsupportedEncodingException, URISyntaxException {
// Retrieve the proper URL components to sign
String resource = path + '?' + query;
// Get an HMAC-SHA1 signing key from the raw key bytes
SecretKeySpec sha1Key = new SecretKeySpec(key, "HmacSHA1");
// Get an HMAC-SHA1 Mac instance and initialize it with the HMAC-SHA1 key
Mac mac = Mac.getInstance("HmacSHA1");
mac.init(sha1Key);
// compute the binary signature for the request
byte[] sigBytes = mac.doFinal(resource.getBytes());
// base 64 encode the binary signature
String signature = Base64.encodeBytes(sigBytes);
// convert the signature to 'web safe' base 64
signature = signature.replace('+', '-');
signature = signature.replace('/', '_');
return resource + "&signature=" + signature;
}
}
代码工作正常:它返回一个URL,但URL给出了这个错误:
- 这是一个错误。 在此服务器上找不到请求的URL / maps / api / place / search / json?。(...)。这就是我们所知道的。

我尝试通过XXXXXXXXXXX更改ClientID(XXXXXXXXXXX.apps.googleusercontent.com),但它仍然无效。谁知道我做错了什么?
非常感谢!

问题是你在谷歌方面没有达到任何终点。即使没有地方 - api-service也能满足您的要求。
尝试使用以下urlString:
private static String urlString = "http://maps.googleapis.com/maps/api/place/search/json?location=..."
重要的区别是googleapis
而不是google
。在浏览器中输入您创建的URL然后您会看到,您获得了一些json(即使它是被拒绝的请求)。然后你知道你达到了api-endpoint。
修改:我认为Google最近已将域名更改为googleapis。您使用的西班牙语文档使用google
,英语文档使用googleapis
。我认为西班牙语文档不是最新的。也许你把这些信息发布到谷歌(可能在论坛上)
