[英]How to send a request (and receive it) in XML format from some web-service?
我在一个电子商务网站上工作,使用 JSF 2。为了与与银行进行所有操作的公司进行通信,我需要将此 XML 发送给他们(这只是他们提供的样本):
<?xml version="1.0" encoding="ISO-8859-1"?>
<requisicao-transacao versao="1.2.0" id="6560a94c-663b-4aec-9a45-e45f278e00b4" xmlns="http://ecommerce.cbmp.com.br">

</requisicao-transacao>
所以在阅读了很多关于如何发送和 XML 并接收它之后,我创建了这个方法:
public String rent(){
//String folderAndFile = createTransaction();
//creating the HTTP Post
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("https://qasecommerce.cielo.com.br/servicos/ecommwsec.do");
try {
//Reading the file as an entity
FileEntity entity = new FileEntity(new File("/home/valter.silva/sample.xml"));
entity.setContentType("text/xml");
post.setEntity(entity);
HttpResponse response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
System.out.println(EntityUtils.toString(httpEntity));
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
但输出总是:
INFO: <?xml version="1.0" encoding="ISO-8859-1"?> <erro xmlns="http://ecommerce.cbmp.com.br"> <codigo>001</codigo> <mensagem>Requisição inválida</mensagem> </erro>
这意味着我发送的.xml
无效。 出于某种原因,XML 是错误的......但是什么?
我发送文件的方式好吗? 我该怎么办?
更新我正在尝试另一种方法,但输出始终相同,...,我的代码有问题吗?
//approach v1
public String rent(){
//String folderAndFile = createTransaction();
try {
File file = new File("/home/valter.silva/test.xml");
HttpPost post = new HttpPost("https://qasecommerce.cielo.com.br/servicos/ecommwsec.do");
post.setEntity(new InputStreamEntity(new FileInputStream(file),file.length()));
post.setHeader("Content-type", "text/xml; charset=ISO-8859-1");
//creating the HTTP Post
DefaultHttpClient client = new DefaultHttpClient();
HttpResponse response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
System.out.println(EntityUtils.toString(httpEntity));
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
//approach v2
public String rent(){
//String folderAndFile = createTransaction();
try {
File file = new File("/home/valter.silva/test.xml");
HttpPost post = new HttpPost("https://qasecommerce.cielo.com.br/servicos/ecommwsec.do");
//creating the HTTP Post
DefaultHttpClient client = new DefaultHttpClient();
String fileInString = fileToString("/home/valter.silva/test.xml");
InputStream inputStream=new ByteArrayInputStream(fileInString.getBytes());//init your own inputstream
InputStreamEntity inputStreamEntity=new InputStreamEntity(inputStream,fileInString.length());
post.setEntity(inputStreamEntity);
HttpResponse response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
System.out.println(EntityUtils.toString(httpEntity));
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
您能否检查您尝试发布的网址是否可以正确处理您的 xml? 我尝试使用简单的 http 帖子将您提供的 xml 上传到指定的 url 并得到
<?xml version="1.0" encoding="ISO-8859-1"?> <erro xmlns="http://ecommerce.cbmp.com.br"> <codigo>001</codigo> <mensagem>Requisição inválida</mensagem> </erro>
我更喜欢您首先尝试从外部上传 xml,然后尝试使用您的代码。 例如,我使用了 Mozilla 插件的 RESTClient。
