我正在开发一个Android应用程序，它将一个json object发送到一个api url，并且应该收到一个json对象作为response，但我一直得到这个error：
BasicNetwork.performRequest: Unexpected response code 400 for http://phoneapi.adro.co/Services/AdService.svc/GetAd/
我正在使用volley。
我的json object到request应该是这样的：
"request": {
"DeviceId": "sdasda" ,
"AppId": "ECC7BCE40126408386BCFCF8AB9187E7",
"AdType": "text",
"Location": "35.7209331,51.472983",
"UserOperator": "Irancell",
"Ip": "127.0.0.1",
"NetworkType": "3G",
"DeviceType": "Android",
"DeviceBrand": "Samsung",
"Width": 0,
"Height": 0,
"TestMode": true
}
这些是我的代码：

答案 0 :(得分：0)
这是因为您在请求中发送了错误的正文。您的服务器期望“请求”作为帖子正文的根参数。这可以通过将sendObj函数更改为以下内容来实现：
public void sendobj() {
final JSONObject jsonBody = new JSONObject();
final JSONObject request = new JSONObject();
try {
request.put("DeviceId", "sdasda");
request.put("AppId", "ECC7BCE40126408386BCFCF8AB9187E7");
request.put("AdType", "text");
request.put("Location", "35.7209331,51.472983");
request.put("UserOperator", "Irancell");
request.put("Ip", "127.0.0.1");
request.put("NetworkType", "3G");
request.put("DeviceType", "Android");
request.put("DeviceBrand", "Samsung");
request.put("Width", "0");
request.put("Height", "0");
request.put("TestMode", "true");
jsonBody.put("request", request);
