这是我用于网络调用的函数。
private void getSample() {
Log.d("", "getSample : ");
OkHttpClient client = new OkHttpClient();
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
client.interceptors().add(interceptor);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(NetworkCalls.BASE_URL)
.client(client)
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
NetworkCalls.CustomerApi customerApi = retrofit.create(NetworkCalls.CustomerApi.class);
Log.e("customerApi Created", "customerApi object Created : ");
customerApi.getCategories("eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjgsImlzcyI6Imh0dHA6XC9cLzE5Mi4xNjguMS42MDo4ODg4XC9DQ1YzXC9wdWJsaWNcL2FwaVwvbG9naW4iLCJpYXQiOjE0NDk0ODg5NDMsImV4cCI6MTQ0OTQ5MjU0MywibmJmIjoxNDQ5NDg4OTQzLCJqdGkiOiI0ODY4ZmNmZDk4OTIxZGQwYjA2ZDZlN2EyYjRjZGMxMSJ9.7c60LRQMFCtqprCbbULgR5xG-FxwXnRUZPuWeMJXcNE")

收到 400 错误请求。

任何帮助将非常感激。
400 听起来像是您从服务器收到的特定错误代码。
您可以通过在Retrofit上添加日志级别来尝试调试。
OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
clientBuilder.addInterceptor(loggingInterceptor);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(NetworkCalls.BASE_URL)
.client(clientBuilder.build())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
添加依赖到gradle
compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'
通过日志级别，您可能会看到从服务器返回的一些错误 json。
Example:
{"statusCode":400,"message":"Some parameters are missing"}
D/Retrofit: <--- END HTTP (76-byte body)
