我使用OkHttp3发布带有value键的json。我已经用邮递员尝试了API网址,它的工作原理。但这在我的android应用中无法正常工作,它总是打印java.io.IOException:stream close。我该怎么办?
protected String doInBackground(Void... voids) {
Log.d("OKHttp3","Post Fuction");
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.sslSocketFactory(SSLSocketClient.getSSLSocketFactory())
.hostnameVerifier(SSLSocketClient.getHostnameVerifier())
.retryOnConnectionFailure(true)
.build();
String Acc = Login_Text_Acc.getText().toString();
String Pwd = Login_Text_Pwd.getText().toString();
Log.d("123456",Acc);
Log.d("123456",Pwd);
RequestBody formBody = new FormBody.Builder()
.add("userID", Acc)
.add("pwd", Pwd)
.build();
Request request = new Request.Builder()
.url(json_url)
.post(formBody)
.build();
try {
Response response = okHttpClient.newCall(request).execute();
if (!response.isSuccessful()) {
return null;
}
if(!response.body().string().equals(""))
{
return response.body().string();
}
return null;
} catch (Exception e) {
e.printStackTrace();
return e.toString();
}
}
这是错误代码:

答案 0 :(得分:0)
您正在尝试消耗响应正文两次。您需要将主体读取为字符串,然后将逻辑应用于该局部变量。
String body = response.body().string();
if (!body.equals("")) {
return body;
}
