我正在尝试使用kotlin中的改造来打击api
这是我的DoinBackGround方法
private fun doinBackground() {
Utility.printMessage("in do in background.....")
try {
val hdr = HashMap<String, String>()
hdr.put("x-csrf-token", Utility.getToken(this.context!!))
val apiInterface = ApiCallRetrofit.getClient(this.mCrypt!!)!!.create(ApiInterface::class.java)
if (what.equals(0)) {
val body = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), getQuery(para))
print("header...")
call = apiInterface.hitApi(url, hdr, body)
} else if (what.equals(1)) {
val imgPart = ArrayList<MultipartBody.Part>()
if (files != null) {
if (files.size > 0) {
for (i in files.indices) {
imgPart.add(preparePart("image/*", "document_file[" + files.get(i).key + "]", files.get(i).file))
}
}
call = apiInterface.hitApiImage(url, hdr, getMap(para), imgPart)
}
call?.enqueue(object : Callback<StandardReposnse> {
override fun onResponse(call: Call<StandardReposnse>, response: Response<StandardReposnse>) {
try {
Utility.printMessage("messege...." + response.body().message)
val resp = Gson().toJson(response.body())
Utility.printMessage("Response :$resp")
Utility.longLogPrint(response.body().data, "Full response : ")
Utility.printMessage("Error : " + Gson().toJson(response.errorBody()))
onPostExecute(Parseresponce(response.body()))
} catch (e: Exception) {
Parseresponce(null)
e.printStackTrace()
}
}
override fun onFailure(call: Call<StandardReposnse>, t: Throwable) {
t.printStackTrace()
if (progressDialog != null) {
progressDialog?.dismiss()
}
Parseresponce(null)
}
})
}
} catch (e: Exception) {
e.printStackTrace()
}
}
这是我定义所有POST方法的界面
@POST
abstract fun hitApi(@Url api: String, @HeaderMap header: Map<String, Any>, @Body body: RequestBody): Call<StandardReposnse>
@POST
fun hitApiNoHeader(@Url api: String, @Body requestBody: RequestBody): Call<StandardReposnse>
@POST
fun test(@Url api: String, @HeaderMap headerMap: Map<String, String>, @Body requestBody: RequestBody): Call<JSONObject>
@Multipart
@POST
fun hitApiImage(@Url api: String, @HeaderMap headerMap: Map<String, String>, @PartMap bodyMap: Map<String, RequestBody>, @Part images: List<MultipartBody.Part>): Call<StandardReposnse>
每当我试图击中Api时，我都会遇到以下异常：
java.lang.IllegalArgumentException: Parameter type must not include a type variable or wildcard: java.util.Map<java.lang.String, ?> (parameter #2)
for method ApiInterface.hitApi
at retrofit2.ServiceMethod$Builder.methodError(ServiceMethod.java:720)
at retrofit2.ServiceMethod$Builder.methodError(ServiceMethod.java:711)
at retrofit2.ServiceMethod$Builder.parameterError(ServiceMethod.java:729)
at retrofit2.ServiceMethod$Builder.build(ServiceMethod.java:193)
at retrofit2.Retrofit.loadServiceMethod(Retrofit.java:166)
这是doinbackground方法中发生异常的行
call = apiInterface.hitApi(url, hdr, body)
我在RequestBody之前尝试了@JvmSuppressWildcards，但它没有用，有人能说明这里的实际问题是什么，加上没有什么东西在日志中打印虽然我用过print（）函数应该用LOGD吗？

您使用过：
ClaimsPrincipal principal = Request.GetRequestContext().Principal as ClaimsPrincipal;
var Name = ClaimsPrincipal.Current.Identity.Name;
例外是：
@POST
abstract fun hitApi(@Url api: String, @HeaderMap header: Map<String, Any>, @Body body: RequestBody): Call<StandardReposnse>
你的hitApi＃2 param实际上使用了通配符：
Parameter type must not include a type variable or wildcard: java.util.Map<java.lang.String, ?> (parameter #2)
尝试指定参数（只需将Any更改为String）。无论如何，你可能不会在请求标题中放置任何对象而不是String。

以下面提到的方式调用它。
val callWeather = NetworkUtils.getApiInterface().getWeatherResponse("03a7949903004a0bb2590633181104", "1.909,45.909", 7)
callWeather.enqueue(object : Callback<APIXUResponse> {
override fun onResponse(call: Call<APIXUResponse>, response: Response<APIXUResponse>) {
var api :APIXUResponse? = response.body()
}
override fun onFailure(call: Call<APIXUResponse>, t: Throwable) {
}
})

这里我有一个完整的例子。
这种依赖性增加了作用
implementation 'com.squareup.retrofit2:retrofit:2.5.0'
annotationProcessor 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
现在在这里创建 ApiClient.kt 文件
object ApiClient {
val BASE_URL = "http://yourwebsite/services/"
private var retrofit: Retrofit? = null
val client: Retrofit
get() {
if (retrofit == null) {
retrofit = Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build()
}
return retrofit!!
}
}
现在创建 APIInterface.kt
@FormUrlEncoded
@POST("users/login")
fun POST_LOGIN(
@Field("imei_number") imei_number: String,
@Field("device_token") device_token: String,
@Field("mobile") mobile: String,
@Field("password") password: String
): Call<LoginResponse>
@GET("general/init-data")
fun GENERAL_MODULE(
@Header("Authorization") auth_key: String
): Call<InitResponse>
@GET("event-gallery/list")
fun GET_Event_GALLERY(
@Header("Authorization") auth_key: String
): Call<EventListResponse>
@GET("event-gallery/photo-list")
fun GET_Event_GALLERY_PHOTO(
@Header("Authorization") auth_key: String,
@Query("id") id: Int
): Call<EventGallerListResponse>
如果有任何用于令牌的标头，则使用@Header，并且在调用@GET时，使用@Query和@Post时使用@Fields
现在的响应文件
data class EventListResponse(
@SerializedName("success")
var success: Boolean,
@SerializedName("data")
var data: EventgalleryModel?,
@SerializedName("server_error"),
@SerializedName("eventgallery")
var eventgallery: ArrayList<EventListData>
var server_error: Boolean,
@SerializedName("message")
var message: String
）
然后创建Response的Model类
现在需要活动代码
private fun loadData() {
card_progress.visibility = View.VISIBLE
val apiService = ApiClient.client.create(ApiInterface::class.java)
val call =
apiService.GET_FEE_INSTALMENT_LIST(PreferenceManager.getAuthKey(this@FeesInstalmentActivity)!!)
call.enqueue(object : Callback<FeeInstalmentListResponse> {
override fun onResponse(
call: Call<FeeInstalmentListResponse>,
response: Response<FeeInstalmentListResponse>
) {
card_progress.visibility = View.GONE
val data = response.body()!!.data
if (response.code() == 200 && data != null) {
if (response.body()!!.server_error) {
txt_no_data_fee.visibility = View.VISIBLE
txt_no_data_fee.text = response.body()!!.message
} else {
Log.e("data", data.toString())
if (data != null && data.feesinstalment.isEmpty()) {
txt_no_data_fee.visibility = View.VISIBLE
} else {
txt_no_data_fee.visibility = View.GONE
adapter!!.setItem(data.feesinstalment)
}
}
} else if (response.code() == 401) {
PreferenceManager.removePref(this@FeesInstalmentActivity)
startActivity(
Intent(this@FeesInstalmentActivity, LoginActivity::class.java)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_CLEAR_TASK or Intent.FLAG_ACTIVITY_NEW_TASK)
)
finish()
} else {
Toast.makeText(
this@FeesInstalmentActivity,
R.string.somethingWrong,
Toast.LENGTH_SHORT
).show()
}
}
override fun onFailure(call: Call<FeeInstalmentListResponse>, t: Throwable) {
card_progress.visibility = View.GONE
Log.e("onFailure", t.message)
txt_no_data_fee.visibility = View.VISIBLE
}
})
}
适配器
class FeeInstalmentAdapter(
private val context: Context,
private var items: ArrayList<FeeInstalmentListData>
）：RecyclerView.Adapter（）{
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
return ViewHolder(LayoutInflater.from(context).inflate(R.layout.row_fees_instalment_item, parent, false))
}
@SuppressLint("SetTextI18n")
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.due_date.text = DateHelper.parseData(items[position].due_date!!, "yyyy-MM-dd", "dd MMM yyyy")
holder.instalment_title.text = items[position].instalment_title
if (items[position].paid_date == null) {
holder.paid_text.visibility = View.GONE
holder.paid_date.text = context.resources.getString(R.string.UnPaid)
holder.paid_date.setTextColor(Color.parseColor("#DC143C"))
} else {
holder.paid_date.text = DateHelper.parseData(items[position].due_date!!, "yyyy-MM-dd", "dd MMM yyyy")
holder.paid_date.setTextColor(Color.parseColor("#58A259"))
}
//holder.paid_date.text = items[position].paid_date
holder.amount.text = "Rs. " + items[position].amount
holder.amount.setTextColor(Color.parseColor("#ED7136"))
}
override fun getItemCount(): Int {
return items.size
}
override fun getItemId(position: Int): Long {
return position.toLong()
}
override fun getItemViewType(position: Int): Int {
return position
}
fun setItem(holidays: ArrayList<FeeInstalmentListData>) {
items = holidays
notifyDataSetChanged()
}
class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
val due_date = view.due_date
val instalment_title = view.instalment_title
val paid_date = view.paid_date
val amount = view.amount
val paid_text = view.paidText
}
}
