【问题描述】：
在我的 android 应用程序中，我正在发送一个凌空 POST 请求，但它不工作。而是发送空参数。
如果我在邮递员中输入 url (https://blogurl.com/wp-json/wp/v2/comments?post=20081&author_name=Ozuf&author_email=myemail@my.com&content=This_is_a_sampe_comment) 并发送 POST 请求，它会产生所需的结果。
Postman 为 JAVA OKHttp 生成的代码如下所示：
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("https://blogurl.com/wp-json/wp/v2/comments?post=20081&author_name=Ozuf&author_email=myemail@my.com&content=This_is_a_sampe_comment")
.post(null)
.addHeader("cache-control", "no-cache")
.addHeader("postman-token", "23f2c2587-e9eb-5446-3d73-a1a1a6814683")
.build();
Response response = client.newCall(request).execute();
这是我用来发送 POST 请求的代码：
public void submitComment() {
final String comment = commentContent.getText().toString().trim();
final String name = commentName.getText().toString().trim();
final String email = commentEmail.getText().toString().trim();
Log.d(TAG, "submitComment called");
if (allFieldsAreValid()) {
Log.d(TAG, "All fields are valid");
final String postComment = "https://blogurl.com/wp-json/wp/v2/comments?";
final PostingComment postingComment = PostingComment.newInstance();
postingComment.show(getFragmentManager(), "fragmentDialog");
JsonObjectRequest postDetails = new JsonObjectRequest(Method.POST, postComment, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
parseResponse(response);
postingComment.dismiss();
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d(TAG, "onErrorResponse for getPost called");
VolleyLog.d(TAG, "Error: " + error.getMessage());
postingComment.dismiss();
if (sthWrongAlert != null) {
sthWrongAlert.show();
}
}
}) {
@Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("post", comtUrl);
params.put("author_name", name);
params.put("author_email", email);
params.put("content", comment);
return params;
}
};
int retrytimes = 10;
RetryPolicy policy = new DefaultRetryPolicy(DefaultRetryPolicy.DEFAULT_TIMEOUT_MS, retrytimes, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
postDetails.setRetryPolicy(policy);
//Creating requestqueue
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
//Adding request queue
requestQueue.add(postDetails);
Log.d(TAG, "Data sent is " + comment + name + email);
} else {
Log.d(TAG, "All fields are not valid");
}
}
正如我之前所说，请求为真，但参数并未随之发送。

应用 djodjo 回答后
public void submitComment() {
String comment = null;
try {
comment = URLEncoder.encode(commentContent.getText().toString().trim(), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
String name = null;
try {
name = URLEncoder.encode(commentName.getText().toString().trim(), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
String email = null;
try {
email = URLEncoder.encode(commentEmail.getText().toString().trim(), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
Log.d(TAG, "submitComment called");
if (allFieldsAreValid()) {
Log.d(TAG, "All fields are valid");
final String postComment = "https://blogurl.com/wp-json/wp/v2/comments?post="+comtUrl+"&content="+comment+"&author_name="+name+"&author_email="+email;
final PostingComment postingComment = PostingComment.newInstance();
postingComment.show(getFragmentManager(), "fragmentDialog");
JsonObjectRequest postDetails = new JsonObjectRequest(Method.POST, postComment, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
parseResponse(response);
postingComment.dismiss();
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d(TAG, "onErrorResponse for getPost called");
VolleyLog.d(TAG, "Error: " + error.getMessage());
postingComment.dismiss();
if (sthWrongAlert != null) {
sthWrongAlert.show();
}
}
}) {
@Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}
};
int retrytimes = 10;
RetryPolicy policy = new DefaultRetryPolicy(DefaultRetryPolicy.DEFAULT_TIMEOUT_MS, retrytimes, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
postDetails.setRetryPolicy(policy);
//Creating requestqueue
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
//Adding request queue
requestQueue.add(postDetails);
Log.d(TAG, "Data sent is " + comment + name + email);
} else {
Log.d(TAG, "All fields are not valid");
}
}
应用他的解决方案后，这就是我的代码的样子。但我不断收到错误 409。

【问题讨论】：
-
这种类型的请求不会像你期望的那样发送参数。你期待它的 json 响应吗？
-
消息是什么
-
@djodjo 是的，我期待它的 json 响应。我的问题最后一行的消息。
