我在一个电子商务网站上工作,使用JSF 2。为了与银行进行所有操作的公司进行通信,我需要向他们发送以下XML(这只是他们提供的一个示例):
<?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>
因此,在阅读了大量有关如何发送和接收XML的内容之后,我创建了以下方法:
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;
}
但输出始终为:
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
是无效的。由于某种原因,XML是错误的...但是什么呢?
我发送文件的方式没问题吧?我能做些什么呢?
update我尝试了另一种方法,但输出仍然是相同的,...,我的代码有什么问题吗?
//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;
}

你能检查一下你要发布的url是否能正确处理你的xml吗?我试着用简单的http post把你提供的xml上传到指定的url,结果得到了
我更喜欢你先尝试从外面上传xml,然后用你的代码试试。例如,我用了Mozilla addon的RESTClient。
