我正在尝试使用齐射将一些数据发布到自定义API。这也是我也在尝试更新信息的API模型。可以在以下POST链接下的http://ecoproduce.eu/swagger/index.html上找到它:http://ecoproduce.eu/api/User/register/
{
"firstName": "string",
"lastName": "string",
"email": "string",
"password": "string",
"zipCode": 0,
"state": 0,
"account": 0
}
[当我尝试向API添加新的测试用户时,出现以下错误:
E/Volley: [9583] BasicNetwork.performRequest: Unexpected response code 400 for http://ecoproduce.eu/api/User/register/
E/Error response: com.android.volley.ClientError
这是我用来发布用户的功能。
private void addUser() {
RequestQueue requestQueue = Volley.newRequestQueue(this);
JsonArrayRequest arrayRequest = new JsonArrayRequest(
Request.Method.POST,
"http://ecoproduce.eu/api/User/register/",
null,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("Error response", error.toString());
}
})
{
@Override
protected Map<String,String> getParams() {
Map<String,String> params = new HashMap<String,String>();
params.put("firstName", "Vasko");
params.put("lastName", "Vasilev");
params.put("email", "[email protected]");
params.put("password", "18yoBonev");
params.put("zipCode", "0");
params.put("state", "1");
params.put("account", "2");
return params;
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
requestQueue.add(arrayRequest);
}
我曾尝试查找解决方案,但找不到任何有用的方法。因为我试图将zipCode,state和account作为字符串传递,即使它们是模型中的整数,也会发生错误吗?如果是这样,如何将它们作为整数传递?目前,我正在重写getParams()函数,该函数必须返回Map实例。如果这个问题有一个简单的解决方案,我想提前道歉,这是我第一次使用RESTful API。
通过使用字符串请求解决。找到答案:How to send a POST request using volley with string body?
当前代码如下:
private void addUser() {
JSONArray jsonArray = new JSONArray();
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("firstName", "Vasko");
jsonObject.put("lastName", "Vasilev");
jsonObject.put("email", "[email protected]");
jsonObject.put("password", "18yoBonev");
jsonObject.put("zipCode", 0);
jsonObject.put("state", 1);
jsonObject.put("account", 2);
jsonArray.put(jsonObject);
} catch (JSONException e) {
e.printStackTrace();
}
RequestQueue requestQueue = Volley.newRequestQueue(this);
final String requestBody = jsonObject.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, "http://ecoproduce.eu/api/User/register", new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.i("VOLLEY", response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("VOLLEY", error.toString());
}
}) {
@Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
@Override
public byte[] getBody() {
try {
return requestBody == null ? null : requestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
return null;
}
}
@Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
// can get more details such as response.headers
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
}
