在Java中将PayPal curl请求转换为http请求 [英] Transforming a PayPal curl request to an http request in Java
本文介绍了在Java中将PayPal curl请求转换为http请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在PayPal网站上，所有示例调用都使用curl。在Linux下很容易重复使用CURL，但我想使用Java来进行这些调用。
例如，假设有调用：
curl -v https://api.sandbox.paypal.com/v1/payments/payment \
-H'Content-Type： application / json'\
-H'授权：承载< Access-Token>'\
-d'{
intent：sale，
redirect_urls：{
return_url：http://example.com/your_redirect_url.html，
cancel_url：http://example.com/your_cancel_url.html
payer：{
payment_method：paypal
} ：{
total：7.47，
currency：USD
}
}
]
}'
假设我有< Access-Token> 必须设置，如何将上一个字符串转换为http请求从PayPal使用Java和没有CURL的答案？
现在我对URL的HttpURLConnection做了类似下面的事情：
private HttpURLConnection createPOSTHttpURLConnection（final URL url） throws IOException {
final HttpURLConnection connection =（HttpURLConnection）url.openConnection（）;
connection.setRequestMethod（POST）;
connection.setUseCaches（false）;
connection.setDoInput（true）;
connection.setDoOutput（true）;
connection.setRequestProperty（User-Agent，Mozilla / 4.0）;
return connection;
}
在我的主要我做如下：
final HttpURLConnection connection = createPOSTHttpURLConnection（url）;
connection.setRequestProperty（Authorization，Bearer< Access-Token>）; //用真实值替换
connection.setRequestProperty（Content-Type，application / json）;
final String jsonData ={\intent\：\sale\，\redirect_urls\：{\return_url\：\http：// example.com/your_redirect_url.html\，\cancel_url\：\http://example.com/your_cancel_url.html\}，\payer \：{\ payment_method \：\paypal\}，\transactions\：[{\amount \：{\total\：\7.47\ \\货币：美元\}}]};
connection.setFixedLengthStreamingMode（jsonData.length（））;
//获取POST到的输出流。
try（final DataOutputStream output = new DataOutputStream（connection.getOutputStream（）））{
output.writeBytes（jsonData）;
output.flush（）;
}
final InputStream isToBeRead = connection.getInputStream（）;但是，我得到以下错误：
无法从给定的URL中读取https://api.sandbox.paypal.com/v1/payments/payment与给定的参数和数据
当我尝试使用 InputStream 时会出现：
java.net.HttpRetryException：无法在流模式下通过服务器身份验证重试
at sun.net.www.protocol.http.HttpURLConnection.getInputStream0 HttpURLConnection.java:1636）
at sun.net.www.protocol.http.HttpURLConnection.getInputStream（HttpURLConnection.java:1439）
at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream HttpsURLConnectionImpl.java:254）
at com.sudengut.de.utils.url.HttpClient.readFromHttpURL（HttpClient.java:65）
UPDATE
服务器返回HTTP响应代码： 400的URL：https://api.sandbox.paypal.com/v1/payments/payment
响应代码：400
响应消息：错误请求
实施 Garry 的答案我获得以下日志：

On the PayPal website, all the example calls are done using curl. Easy to repeat using CURL under Linux, but I would like to use Java to make these calls.
E.g., suppose to have the call:
curl -v https://api.sandbox.paypal.com/v1/payments/payment \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer <Access-Token>' \
-d '{
"intent":"sale",
"redirect_urls":{
"return_url":"http://example.com/your_redirect_url.html",
"cancel_url":"http://example.com/your_cancel_url.html"
},
"payer":{
"payment_method":"paypal"
},
"transactions":[
{
"amount":{
"total":"7.47",
"currency":"USD"
}
}
]
}'
Suppose that I have the value for <Access-Token> that has to be set, how can I convert the previous string into an http request to get an answer from PayPal using Java and no CURL?
Right now I did something like the following to the an HttpURLConnection to the URL:
private HttpURLConnection createPOSTHttpURLConnection(final URL url) throws IOException {
final HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setUseCaches(false);
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestProperty("User-Agent", "Mozilla/4.0");
return connection;
}
In my main I do as follows:
final HttpURLConnection connection = createPOSTHttpURLConnection(url);
connection.setRequestProperty("Authorization", "Bearer <Access-Token>");//replaced with a real value
connection.setRequestProperty("Content-Type", "application/json");
final String jsonData = "{ \"intent\":\"sale\", \"redirect_urls\":{ \"return_url\":\"http://example.com/your_redirect_url.html\", \"cancel_url\":\"http://example.com/your_cancel_url.html\" }, \"payer\":{ \"payment_method\":\"paypal\" }, \"transactions\":[ { \"amount\":{ \"total\":\"7.47\", \"currency\":\"USD\"}}]}";
connection.setFixedLengthStreamingMode(jsonData.length());
// get the output stream to POST to.
try(final DataOutputStream output = new DataOutputStream(connection.getOutputStream())) {
output.writeBytes(jsonData);
output.flush();
}
final InputStream isToBeRead = connection.getInputStream();
However, I get the following error:
Cannot read from the given URL https://api.sandbox.paypal.com/v1/payments/payment with given params and data
Tha occcurs when I try to use the InputStream:
java.net.HttpRetryException: cannot retry due to server authentication, in streaming mode
at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1636)
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1439)

at com.sudengut.de.utils.url.HttpClient.readFromHttpURL(HttpClient.java:65)
UPDATE
Implementing Kevin Hoffman'solution I get the following result:
Server returned HTTP response code: 400 for URL: https://api.sandbox.paypal.com/v1/payments/payment
Response code:400
Response message:Bad Request
Implementing Garry's answer I obtain the following log:

If I implement this question with some more info, I see that the given cookie is appended and doesn't replace the one with a missing expiration date. Just run:
import java.time.Instant;
import java.time.LocalDate;
import java.time.ZoneId;
import java.time.temporal.ChronoUnit;
import java.util.Date;
import org.apache.http.HttpResponse;
import org.apache.http.client.CookieStore;
import org.apache.http.client.HttpClient;
import org.apache.http.client.config.CookieSpecs;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.protocol.HttpClientContext;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.BasicCookieStore;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.impl.cookie.BasicClientCookie;
import org.apache.http.protocol.HTTP;
public class GarrysSolution {
public static void main(final String[] args) {
String accessToken = "A-valid-token";
String jsonString =
"{ \"intent\":\"sale\",\"redirect_urls\":{ \"return_url\":\"http://example.com/your_redirect_url.html\", \"cancel_url \":\"http://example.com/your_cancel_url.html\" }, \"payer\":{\"payment_method\":\"paypal\"},\"transactions\":[{ \"amount\":{ \"total\":\"7.47\", \"currency\":\"USD\"}}]}";
BasicCookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID", "1234");
cookie.setDomain(".paypal.com");
cookie.setPath("/");
LocalDate expirationDate = LocalDate.now().plus(100L, ChronoUnit.DAYS);
Instant instant = Instant.from(expirationDate.atStartOfDay(ZoneId.of("GMT")));
cookie.setExpiryDate(Date.from(instant));
cookie.setCreationDate(Date.from(Instant.now()));
cookieStore.addCookie(cookie);
RequestConfig globalConfig = RequestConfig.custom().setCookieSpec(CookieSpecs.NETSCAPE).build(); HttpClientContext context = HttpClientContext.create();
context.setCookieStore(cookieStore);
HttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(globalConfig)
.setDefaultCookieStore(cookieStore).build();
HttpPost httpPost = new HttpPost("https://api.sandbox.paypal.com/v1/payments/payment");
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Authorization", "Bearer " + accessToken);
StringEntity entity = new StringEntity(jsonString, HTTP.UTF_8);
entity.setContentType("application/json");
httpPost.setEntity(entity);
try {
HttpResponse httpResponse = httpClient.execute(httpPost, context);
System.out.println("\n\n" + context.getCookieStore().getCookies());
System.out.println("\n\n" + httpResponse.getStatusLine().getStatusCode() + "/"
+ httpResponse.getStatusLine().getReasonPhrase());
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}
and we see the following cookies from the context:
[[version: 0][name: JSESSIONID][value: 1234][domain: .paypal.com][path: /][expiry: Fri Nov 06 01:00:00 CET 2015], [version: 0][name: X-PP-SILOVER][value: name%3DSANDBOX3.API.1%26silo_version%3D880%26app%3Dplatformapiserv%26TIME%3D2370156885][domain: .paypal.com][path: /][expiry: null]]
So I guess that the problem can be solved by setting the expiration date to the proper cookie
解决方案 I just repaste the Kevin's code after removing all the spaces under the "JsonData" variable and replacing the real token and it works fine .
