jem*_*ili 5 android http kotlin retrofit2
我正在使用改造,我有一个发布请求
interface NetworkApi {
@Headers("Content-Type: application/json")
@POST("/")
fun startLoginRequest(@Body loginModel : LoginModel) : Call<BaseResponseModel>
class Factory {
var retrofit = Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build()
companion object{
fun getApi (): NetworkApi {
val serverApi = NetworkApi.Factory()
val api = serverApi.retrofit.create(NetworkApi::class.java)
return api
}
}
}
}
当我使用这个方法并且在响应方法上调用响应体时总是为null.
fun startLoginRequest(){
val api = NetworkApi.Factory.getApi()
val request = api.startLoginRequest(loginRequestModel)
request.enqueue(object : Callback<BaseResponseModel>{
override fun onFailure(call: Call<BaseResponseModel>?, t: Throwable?) {
}
override fun onResponse(call: Call<BaseResponseModel>?, response: Response<BaseResponseModel>?) {
//here response.body is null
}
})
}
奇怪的是,如果我使用Postman发送相同的对象,一切正常
这是httpClient拦截器日志
--> POST http://myExampleHost.net/ http/1.1
Content-Type: application/json
Content-Length: 95
Authorization: auth-value
--> END POST (95-byte body)
<-- 405 Method Not Allowed http://myExampleHost.net/ (198ms)

现在我正在使用OkHttp RequestBuilder,一切正常,我没有意识到我在上面的例子中缺少了什么
val client = OkHttpClient()
val JSON = MediaType.parse("application/json; charset=utf-8")
val body = RequestBody.create(JSON,json)
val request1 = Request.Builder()
.url("http:example.com")
.addHeader("content-type", "application/json")
.method("POST", body)
.build()
client.newCall(request1).enqueue(object : okhttp3.Callback{
override fun onFailure(call: okhttp3.Call?, e: IOException?) {
}
override fun onResponse(call: okhttp3.Call?, response: okhttp3.Response?) {
response?.body()?.string()?.print("RETROFIT response")
}
})

对我来说，主要原因是我调用了http而不是https 例如：我使用这个 url 作为基本 url，这给了我这个错误
http://www.facebook.com/
当我把它改成这个时，它就像一种魅力
https://www.facebook.com/

我最好的猜测是你试图发布错误的网址www.example.com/login//而不是www.example.com/login/.关于帖子,API可能有点挑剔.
您可以添加日志记录拦截器,以便查看您发布的内容和URL,以便更容易调试.要进行设置,您需要添加compile "com.squareup.okhttp3:logging-interceptor:$okhttp_version"到gradle文件并将改进设置更改为以下内容:
val httpClient = OkHttpClient.Builder().apply {
if (BuildConfig.DEBUG) {
httpClient.addInterceptor(HttpLoggingInterceptor().apply {
level = HttpLoggingInterceptor.Level.BODY
})
}
}
var retrofit = Retrofit.Builder()
.client(httpClient.build())
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build()
这是我可以给出的最好的建议,而不会看到错误日志.
我找到了答案，问题是 url，我的 baseUrlhttp//www.example.com/url1/url2/...../service
是@POST("/")
当我看到 POST 端点时，它是http://www.example.com/，我不知道为什么
我刚刚更改了这个
baseUrl = http//www.example.com/
网址@POST("url1/url2/...../service")
