Android 如何将webservice参数作为JSON对象传递？

Android新增的webservice调用返回状态代码400。我怀疑这是由于传递参数的方式不正确造成的。我需要将它们作为JSON对象传递，但不确定如何才能做到这一点

下面应该是参数，并且工作正常

在我的Android代码中，它显示状态代码400

（更新代码如下）

但是它返回了请求错误xml

欢迎提出任何建议。非常感谢。

您确定您的url

http://192.168.0.102/DService/ServiceSD.svc/LoginUser?Query=login=WT&password=03&includeUserMiscInfo=true

是否正确？

您可以使用以下方法调用您的web服务：

public void makeHTTPCall() {

        RequestParams params = new RequestParams();
        String query = "[login=WT&password=03]"
        params.put("query", query);
        params.put("includeUserMiscInfo", "true");

        prgDialog.setMessage(getResources().getString(R.string.please));
        AsyncHttpClient client = new AsyncHttpClient();

        client.post("http://192.168.0.102/SDService_SAFTI/ServiceSD.svc/LoginUser",
                params, new AsyncHttpResponseHandler() {

            @Override
            public void onSuccess(String response) {
                // Hide Progress Dialog
                prgDialog.hide();       

// do your code if result is success

            }


            @Override
            public void onFailure(int statusCode, Throwable error,
                    String content) {

                prgDialog.hide();

                if (statusCode == 404) {
                    Toast.makeText(getApplicationContext(),
                            "Requested resource not found",
                            Toast.LENGTH_LONG).show();
                }

                else if (statusCode == 500) {
                    Toast.makeText(getApplicationContext(),
                            "Something went wrong at server end",
                            Toast.LENGTH_LONG).show();
                }

                else {
                    Toast.makeText(
                            getApplicationContext(),
                            getResources().getString(R.string.some_error_occured)
                            , Toast.LENGTH_LONG)
                            .show();
                }
            }
        });
    }

希望这对您有所帮助。

是正确的。我不知道如何传递参数？我也尝试过使用Requestparams。请查看高级客户端url（正确）。您的更新代码看起来正确。您是否仍然收到400错误或其他错误（logcat中的任何错误）？仍然相同的状态代码=400。请求错误。Android监视器上没有错误。请看一看，您可能需要结合一些方法map=new HashMap（）；地图放置（“登录”、“WT”）；地图放置（“密码”、“03”）；参数put（“用户”，映射）；//url参数：“用户[名字]=James和用户[姓氏]=Smith”参数put（“查询”，映射）；参数put（“includeUserMiscInfo”、“true”）；KishuDroid，看截图。我的webservices参数没有那么简单。查询中包含2项-登录名和密码。includeUserMiscInfo是另一个参数。实际上，您传递的格式不正确。所以试着像这样通过它。查看我的编辑我使用的正是您提到的：RequestParams params=newrequestparams（）；字符串查询=“[login=WT&password=03]”参数放置（“查询”，查询）；参数put（“includeUserMiscInfo”、“true”）；参数put（“用户”，映射）；参数put（“查询”，map）；这是什么.sry参数.put（“用户”，映射）；这是额外的。更新了代码。但还是一样的错误。我的问题在这里得到解决-->
