[英]how to send the url post using httpclient
我使用httpclient如下登錄到我的項目:
public void login(String username,String password){
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://localhost:8080/j_spring_security_check");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("j_username", username));
nameValuePairs.add(new BasicNameValuePair("j_password", password));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
} catch (IOException e) {
e.printStackTrace();
}
}
我使用上面的類似以下內容:
HttpClientRequests httpRequest = new HttpClientRequests();
httpRequest.login("mayank","hexgen");
現在我想發送POST
請求,請求方法如下:
@RequestMapping(method = RequestMethod.POST, value = "/trade/createrequisition")
public @ResponseBody
void createRequisition(@RequestBody CreateRequisitionRO[] request,
@RequestHeader("validateOnly") boolean validateOnly) {
....
}
所以我創建了如下反射:
HttpClientRequests httpRequest = new HttpClientRequests();
Class[] paramString = new Class[1];
paramString[0] = String.class;
Class parames = CreateRequisitionRO[].class;
CreateRequisitionRO[] roRqequest = new CreateRequisitionRO[1];
boolean istrueOrFalse=true;
Class booleanVal ;
booleanVal = Boolean.TYPE;
Class cls;
try {
cls = Class.forName("com.hexgen.api.facade.HexgenWebAPI");
Method method = cls.getDeclaredMethod("createRequisition", parames,booleanVal);
RequestMapping methodRequestMappingAnnotation = method.getAnnotation(RequestMapping.class);
RequestMethod[] methods = methodRequestMappingAnnotation.method();
String[] mappingValues = methodRequestMappingAnnotation.value();
//String methodType = methods[0].name();
//String url = mappingValues[0];
httpRequest.login("mayank","hexgen");
}catch(Exception ex){
ex.printStackTrace();
}
現在在此httpRequest.login("mayank","hexgen");
如何發送請求以訪問以下方法:
@RequestMapping(method = RequestMethod.POST, value = "/trade/createrequisition")
public @ResponseBody
void createRequisition(@RequestBody CreateRequisitionRO[] request,
@RequestHeader("validateOnly") boolean validateOnly) {
....
}
所以。
我能夠以編程方式登錄系統,但成功登錄后無法調用。
請幫助我解決此問題。
這取決於服務可以接受哪種內容。 Xml / json /什么?
我看到您獲得了必須通過反射郵寄的地址。 您應該發布到該地址的內容是編入json / xml(?)的CreateRequisitionRO
數組。 將它們編組后,只需發送該郵件集作為請求實體的帖子即可。 然后,服務器端應解組請求內容,並調用createRequisition()
處理程序方法。
編組的完成方式取決於您的項目。 為此,有很多庫,我猜JAXB是最流行的。
