我一直在从事具有node.js后端并与sql server中的数据库通信的android项目，并且IOException不断向我显示：
caused by java.io.EOFException: \n not found: limit=0 content=…
这是整个堆栈跟踪：

我一直在看，正在阅读教程以确保我正确构建API和连接代码，并阅读其他有相同问题的人，然后做他们没有做的事情解决了我的问题。
这是我的node.js代码：
var postData = req.body; // get post params
var userId = uid.v4();
const userExistQuery = 'SELECT email, first_name, last_name FROM User WHERE email = @email AND category = @category AND password = @password';
if(postData.category.valueOf() == new String("Seller").valueOf()){
connection.request()
.input('email', sql.VarChar(45), postData.email)
.input('password', sql.VarChar(45), postData.password)
.input('category', sql.VarChar(45), postData.category)
.query(userExistQuery)
.then((recordSet)=>{
if(recordSet.rowsAffected == 1){
res.json("Already registered as Seller.");
}else{
var streetNum = postData.streetNum;
var buildingNum = postData.buildingNum;
var apartmentNum = postData.apartmentNum;
var town = postData.town;
var governance = postData.governance;
var floorNum = postData.floorNum;
var poBox = postData.poBox;
var zipCode = postData.zipCode;
var creditInfo = postData.creditInfo;
const addSellerQuery =
'INSERT INTO Seller(seller_id, street#, building#, apartment#, town, governance, floor#, P.O_box, zip_code, credit_info, first_name, last_name, email, password, phone_number ,category) VALUES(@sellerId,@streetNum,@buildingNum,@apartmentNum,@town,@governance,@floorNum,@poBox,@zipCode,@creditInfo,@firstName,@lastName,@email,@password, @phoneNumber, @category)';
connection.request()
.input('sellerId', sql.VarChar(45), userId)
.input('streetNum', sql.VarChar(45), postData.streetNum)
.input('buildingNum', sql.VarChar(45), postData.buildingNum)
.input('apartmentNum', sql.VarChar(45), postData.apartmentNum)
.input('town', sql.VarChar(45), postData.town)
.input('governance', sql.VarChar(45), postData.governance)
.input('floorNum', sql.VarChar(45), postData.floorNum)
.input('poBox', sql.VarChar(45), postData.poBox)
.input('zipCode', sql.VarChar(45), postData.zipCode)
.input('creditInfo', sql.VarChar(45), postData.creditInfo)
.input('firstName', sql.VarChar(45), postData.firstName)
.input('lastName', sql.VarChar(45), postData.lastName)
.input('email', sql.VarChar(45), postData.email)
.input('password', sql.VarChar(45), postData.password)
.input('phoneNumber', sql.VarChar(45), postData.phoneNumber)
.input('category', sql.VarChar(45), postData.category)
.query(addSellerQuery)
.then((recordAdded)=>{
if(recordAdded.rowsAffected == 1){
res.json(dataPost.firstName + "Registered as Seller.");
}else{
res.json(dataPost.firstName + "failed to register as Seller.");
}})}
这是我的改造代码：
public static Retrofit getRetrofit() {
if (retrofit == null) {
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.connectTimeout(120, TimeUnit.SECONDS)
.readTimeout(120, TimeUnit.SECONDS)
.writeTimeout(120, TimeUnit.SECONDS)
.build();
retrofit = new Retrofit.Builder()
.baseUrl("http://10.0.2.2:1433/")
.client(okHttpClient)
.addConverterFactory(ScalarsConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
}
return retrofit;
}
此代码如何从api获取数据：
compositeSubs.add(myAPI.buyerSignUp(buyer.getEmail(), buyer.getName().split(" ")[0]
, buyer.getName().split(" ")[1], buyer.getPassword(), buyer.bringType(), buyer.getPhoneNumber())
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(s -> { // onNext method
Log.d(TAG, "onPreExecute get data from api");
((AuthListener) callBack).onSignUp(s, compositeSubs, false);
Log.d(TAG, "onPreExecute after get data from api");
}, throwable -> { // onError method
Log.d(TAG, "onPreExecute getting api error");
throwable.printStackTrace();
}, () -> { // onComplete method
Log.d(TAG, "onPreExecute after getting data from api");
Handler handler = new Handler(Looper.getMainLooper());
handler.post(() -> {
if (progressDialog.isShowing())
progressDialog.dismiss();
});
Log.d(TAG, "completed");
}));
我希望看到新买家已添加到数据库中的Buyer表中，但是此异常阻止添加新买家。
