我正在尝试将我的Android应用程序连接到shutterstock api,以便它可以在那里搜索一些图像。它使用https方案+基本身份验证标头允许用户进行所有搜索请求。我使用HttpsURLConnection在常规Java项目中实现了该功能,并且能够获得正确的JSON响应。 java代码如下所示:
HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();//proxy);
String username = "62c01aa824222683004b", password = "dc4ad748a75e4e69ec853ad2435a62b700e66164";
String encoded = Base64.getEncoder().encodeToString((username+":"+password).getBytes("UTF-8"));
System.out.println(encoded.equals("Nj0jMDFhZWE4ZmE4MjY4MzAwNGI6ZGM0YWQ3NDhhNzVlNGU2gWVjODUzYWQ0ZmEzYTYyYjc7MGU2NjE2NA==")); // prints true
urlConnection.setRequestProperty("Authorization", "Basic "+encoded);
当将其移植到Android中时,它抛出了一个带有401错误代码的IOException。正如SO上的许多帖子(如here中所述)所解释的那样,我使用额外的try-catch
相应地修改了代码,如下所示:
String username = "62c01aa824222683004b", password = "dc4ad748a75e4e69ec853ad2435a62b700e66164", encoded = "";
encoded = Base64.encodeToString((username+":"+password).getBytes("UTF-8"), Base64.URL_SAFE);
Log.e("test", "encoded strings match:" + encoded.equals("Nj0jMDFhZWE4ZmE4MjY4MzAwNGI6ZGM0YWQ3NDhhNzVlNGU2gWVjODUzYWQ0ZmEzYTYyYjc7MGU2NjE2NA==") + "\n" + encoded); // prints false but string is same!!
URL url = new URL(reqUrl);
connection = (HttpsURLConnection) url.openConnection();
connection.setRequestProperty("Authorization", "Basic "+encoded);
try {
if (connection != null) {
connection.connect();
if (200 == connection.getResponseCode()) { // ---> throws IOException
BufferedReader br = new BufferedReader(new InputStreamReader((connection.getInputStream())));
String output;
while ((output = br.readLine()) != null) {
Log.e("test", output);
response.append(output);
}
connection.disconnect();
return response.toString();
}
}
} catch (IOException e) {
try {
Log.e("test", e.getMessage()); // ---> prints "No authentication challenges found"
Log.e("test", connection.getResponseCode() + ":" + connection.getResponseMessage() + connection.getHeaderFields());
//---> prints 401:Unauthorized{null=[HTTP/1.1 401 Unauthorized], cache-control=[no-cache], Connection=[keep-alive], Content-Length=[38], Content-Type=[application/json; charset=utf8], Date=[Tue, 31 May 2016 14:11:28 GMT], Server=[nginx], X-Android-Received-Millis=[1464703888222], X-Android-Sent-Millis=[1464703887592], x-end-user-request-id=[f754ec7f-c344-431b-b641-360aabb70184], x-shutterstock-app-version=[apitwo-625], x-shutterstock-resource=[/v2/images/search]}
if (401 == connection.getResponseCode()) {
InputStream es = connection.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(es));
String output;
while ((output = br.readLine()) != null) {
Log.e("test", output); // ---> prints {"message":"Invalid auth credentials"}
response.append(output);
}
connection.disconnect();
return response.toString();
} else {
Log.e("test","Could not connect! " + connection.getResponseCode() + ":" + connection.getResponseMessage() + ". " + connection.getRequestMethod());
}
}catch (Exception e1){e1.printStackTrace();}
}
我无法检查Firefox的Rest客户端中的响应标头,因为当我添加Authentication标头时它不会将请求发送到服务器。
所以这里的问题是:
答案 0 :(得分:0)
我将java程序中的编码字符串复制到Android变量中,并且能够使用shutterstock成功验证。事实上,Android和Java上的编码字符串虽然采用UTF-8格式,但却有所不同。这也解释了Android中的“false”和来自服务器的“Invalid credentials”消息。
当人眼的编码字符串相同时,只是不确定为什么/它如何不同!
