在Java中将PayPal curl请求转换为http请求
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，假设打电话：在Java中将PayPal curl请求转换为http请求,java,http,curl,paypal,Java,Http,Curl,Paypal,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，假设打电话： curl -v https://api.sandbox.paypal.com/v1/payments/payment \ -H 'Content-Type: application/json' \ -H 'Authorization: Bearer <Access-Token>' \ -d '{ "intent":"sale",

因此，我想通过将过期日期设置为正确的cookie可以解决这个问题。代码在try块中吞咽异常，没有抛出表示发生HTTP错误的捕获。这可能是由于无效的访问令牌造成的。然后，代码尝试读取HTTP响应，但由于401错误导致没有响应，因此读取失败，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 我获得了下面的代码，使用有效的访问令牌成功地与PayPal合作。与您的代码有一些细微的区别，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，但是这些改变都不能单独起作用——他们只是把它收紧了一点，确保它在出错时打印出正确的错误消息。然后，一旦我提供了一个有效的访问令牌，它就成功地工作了。我猜想您已经意识到访问令牌周围的尖括号必须移除，否则您将永远无法使用curl方法 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，或者返回到最初使用的try with resources方法

不用说，使用CURL时，一切都很好，JSON以一个“不应该”开头——该引号在CURL请求中用作shell参数分隔符，不随数据一起传递。在发送数据之前，您应该考虑使用JSON库验证/格式化数据。是的，但同时删除不必要的字符，我也会遇到同样的错误。@heeneee我强烈反对！用“使用库”来回答编程问题是什么建议？！？我不认为这符合StackOverflow的精神。所以，如果我问如何在Java 7中实现一个函数，你的标准答案是使用Guava。当然，你有权不同意，但你的目标是使用Java与PayPal交互。PayPal提供了一个库来实现这一点。你为什么不使用它呢？不用说，对于CURL，一切都很好，你的JSON以一个“不应该”开头——这个引号在CURL请求中用作shell参数分隔符，并且不随数据一起传递。在发送数据之前，您应该考虑使用JSON库验证/格式化数据。是的，但同时删除不必要的字符，我也会遇到同样的错误。@heeneee我强烈反对！用“使用库”来回答编程问题是什么建议？！？我不认为这符合StackOverflow的精神。所以，如果我问如何小鬼
在Java7中，你的标准答案是使用番石榴。当然，你有权不同意，但你的目标是使用Java与PayPal交互。PayPal提供了一个库来实现这一点。为什么不使用它呢？我想我会使用PayPal SDK，但我想让这个例子起作用。所以，我做了以下几点。1我请求获得一个有效的令牌，回答是Bearer tokenvalue；2我用给定的令牌重复了你的测试；3输出为：服务器为URL返回HTTP响应代码：400：https://api.sandbox.paypal.com/v1/payments/payment 响应代码：400响应消息：错误的请求我同意SDK可能是一种更好的方式，我不确定为什么这个代码对你不起作用-我可以在这里很好地运行它-我被难住了。嗯，我可以使用PayPal SDK进行调用，但仍然无法使用UrlConnection或HttpClient。我的意思是，我可能会忘记这种方法，但我想知道这里出了什么问题。我想我会使用PayPal SDK，但我想让这个例子起作用。所以，我做了以下几点。1我请求获得一个有效的令牌，回答是Bearer tokenvalue；2我用给定的令牌重复了你的测试；3输出为：服务器为URL返回HTTP响应代码：400：https://api.sandbox.paypal.com/v1/payments/payment 响应代码：400响应消息：错误的请求我同意SDK可能是一种更好的方式，我不确定为什么这个代码对你不起作用-我可以在这里很好地运行它-我被难住了。嗯，我可以使用PayPal SDK进行调用，但仍然无法使用UrlConnection或HttpClient。我的意思是，我可能会忘记这种方法，但我想了解这里出了什么问题。我发布了使用您的解决方案获得的结果。我怀疑还有什么东西不见了。我不能让CURL工作而Java代码不工作。奇怪的最新版本，即第4版。5@mat_boy .. 好吧，看来是饼干的问题。我已更新答案以添加自定义cookies。请尝试此操作。我已更新输出。你确定这是设置cookie的正确方法吗？我想问题出在我的Spring Boot应用程序上。请看，我发布了使用您的解决方案获得的结果。我怀疑还有什么东西不见了。我不能让CURL工作而Java代码不工作。奇怪的最新版本，即第4版。5@mat_boy .. 好吧，看来是饼干的问题。我已更新答案以添加自定义cookies。请尝试此操作。我已更新输出。你确定这是设置cookie的正确方法吗？我想问题出在我的Spring Boot应用程序上。看吧，最后的问题是JSON，哈哈。没错，现在可以了。非常感谢！干得好，伊珊-真希望我能试一下！所以，最后的问题是JSON，哈哈。没错，现在可以了。非常感谢！干得好，伊珊-真希望我能试一下！
