在PayPal网站上，所有示例调用都是使用curl完成的。在Linux下使用CURL很容易重复，但我想使用Java来进行这些调用。
例如，假设有电话：
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"
}
}
]
}'
假设我必须设置<Access-Token>的值，如何将之前的字符串转换为http请求以使用Java从没有CURL的PayPal获得答案？
现在，我对URL的HttpURLConnection执行了以下操作：
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;
}
在我的主要内容中，我做如下：
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();
但是，我收到以下错误：
Cannot read from the given URL https://api.sandbox.paypal.com/v1/payments/payment with given params and data
InputStream：时，发生了Tha
java.net.HttpRetryException: cannot retry due to server authentication, in streaming mode

实施Kevin Hoffman'解决方案我得到以下结果：
Server returned HTTP response code: 400 for URL: https://api.sandbox.paypal.com/v1/payments/payment
Response code:400
Response message:Bad Request

我们从上下文中看到以下Cookie：

所以我想通过将到期日期设置为正确的cookie
可以解决问题答案 0 :(得分：3)
代码正在吞下异常（在没有catch的try块中）被抛出以指示正在发生HTTP错误401（未授权）。这可能是由于访问令牌无效。然后代码尝试读取HTTP响应，并且失败（因为401错误没有响应）并抛出正在打印到屏幕上的异常。
在您设置代码时，访问令牌是否可能已过期？
我使用以下代码（如下）与PayPal一起成功使用有效的访问令牌。与您的代码有一些细微的差别（没有单独的方法;使用HttpsURLConnection而不是HttpUrlConnection;删除了一些不需要的标题;等等），但这些更改都没有使它单独工作 - 它们只是收紧了一点并确保了它出现问题时打印出正确的错误信息。然后，一旦我提供了有效的访问令牌，它就能成功运行我想你必须知道访问令牌周围的尖括号< >必须被移除，否则你永远不会让curl方法起作用。
另外，请记住这只是示例代码 - 生产代码应该将close语句移动到finally块中，或者返回到最初的try-with-resources方法。

您可能想尝试如下的Apache HTTPClient：
BasicCookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID", "1234");
cookie.setDomain(".paypal.com");
cookie.setPath("/");
cookieStore.addCookie(cookie);
String accessToken = "your_access_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\"}}]}";
HttpClient httpClient = HttpClientBuilder.create().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);
System.out.println(httpResponse.getStatusLine().getStatusCode() + "/" + httpResponse.getStatusLine().getReasonPhrase());
