java 调用 C# webapi

最近项目需要 java调用  .net 的webapi。

对于get来说很简单，但是post方法遇到了些问题，最后也是曲线救国。

先看代码

 

Java  代码

 

public static void main(String[] args) throws Exception {
//DoGet(String url)
String resultGet = DoGet("http://localhost:14248/api/Report/GetTest?parentid=40");

//DoPost(String url,List nvps)
List nvps = new ArrayList();
     nvps.add(new BasicNameValuePair("parentid", "40"));
String resultPost = DoPost("http://localhost:14248/api/Report/PostTest",nvps);

//DoPost(String url, JSONObject template)
JSONObject template = new JSONObject();
template.put("data",data);
String json=HttpWebapi.DoPost(urlString,template);

//DoPost(String url, String json)
SysUser user=new SysUser();
user.setAccount(etAccount.getText().toString());
user.setPassword(etPwd.getText().toString());
ApiRequest request=new ApiRequest<>();
request.setData(user);
String data=JsonConvert.toJSON(request);
String json = HttpWebapi.DoPost(AppConfig.getUrl() + "api/user/login", data);
}

public static String DoGet(String url) throws Exception {

HttpGet httpGet = new HttpGet(url);  
        HttpClient client = new DefaultHttpClient();  
        HttpResponse resp = client.execute(httpGet);  
        HttpEntity he = resp.getEntity();  
        String respContent = EntityUtils.toString(he, "UTF-8");  
        return respContent; 
}

public static String DoPost(String url,List nvps) throws Exception {
HttpPost httpost = new HttpPost(url);  
        HttpClient client = new DefaultHttpClient();  
        httpost.setEntity(new UrlEncodedFormEntity(nvps, "UTF-8"));  
        HttpResponse resp = client.execute(httpost);  
        HttpEntity he = resp.getEntity();  
        String respContent = EntityUtils.toString(he, "UTF-8");  
        return respContent; 
}

public static String DoPost(String url, JSONObject template)throws Exception{
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader(HTTP.CONTENT_TYPE, "application/json");
httpPost.setEntity(new StringEntity(template.toString(),"utf-8"));
HttpResponse resp = httpClient.execute(httpPost);
String respContent = EntityUtils.toString(resp.getEntity(), "UTF-8");
return respContent;
}

public static String DoPost(String url, String json) throws Exception{
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(url);
    httpPost.addHeader(HTTP.CONTENT_TYPE, "application/json");
    httpPost.setEntity(new StringEntity(json,"utf-8"));
    HttpResponse resp = httpClient.execute(httpPost);
    String respContent = EntityUtils.toString(resp.getEntity(), "UTF-8");
    return respContent;
}
 

 

 

C# WebApi

//public static String DoGet(String url) 
[HttpGet]
public dynamic GetTest(int parentId)
{
APIResult<dynamic> result = new APIResult<dynamic>();
result.Data = report.Get_SanJu_ReportSiteCount(parentId);
result.ResponseResult = true;
result.ResponseMsg = "success";
result.ResponseCode = HttpStatusCode.OK;

return result;
}

//public static String DoPost(String url, List nvps)
[HttpPost]
public dynamic PostTest()
{
//通过[FormBody]并不能从方法参数上获得parentId，所以直接从 Request.Form获取
int parentId = int.Parse(HttpContext.Current.Request.Form["parentId"]);
APIResult<dynamic> result = new APIResult<dynamic>();
result.Data = report.Get_SanJu_ReportDesulphurizationTypeByParentId(parentId);
result.ResponseResult = true;
result.ResponseMsg = "success";
result.ResponseCode = HttpStatusCode.OK;

return result;
}

 

 

Java WebApi

//public static String DoPost(String url, JSONObject template)

@Data
public class ApiRequest {
private T data; 
private Integer pageIndex = 1;
private Integer pageSize; 
}



@RequestMapping(value = "test", method = RequestMethod.POST)
public ApiResult test(String test, @RequestBody ApiRequest requestVo) {
ApiResult r = new ApiResult();

r.setData(requestVo.getData());
r.setCodeToSuccessed();
return r;
}

 

//public static String DoPost(String url, String json)

@RequestMapping(value = "login", method = RequestMethod.POST)
public ApiResult login(@RequestBody ApiRequest requestVo) {
ApiResult r = new ApiResult();
SysUser entity = requestVo.getData();
String source = requestVo.getSource();
String platformUUID = entity.getPlatformUUID();
SysUser u = service.getByAccount(entity.getAccount());
// 验证登录成功
if (u != null && u.getPassword().equals(MD5.md5(entity.getPassword()))) {
if(u.getIsValid()==1){
u.setPassword("");//把密码设置为空
r.setData(u);
r.setCodeToSuccessed();
}else {
r.setMessage("The account has been locked!");
}
}else{
r.setMessage("Account or password invalid!");
}

return r;
}
