android http设置body,Okhttp中如何在拦截器中的RequestBody添加参数？

可以遍历formBody，循环添加 formBody

最好的办法是重写 FormBody，追加添加参数的方法。

OkHttpClient.Builder httpClient = new OkHttpClient.Builder()

httpClient.addInterceptor(new Interceptor() {

@Override

public Response intercept(Chain chain) throws IOException {

Request original = chain.request();

//请求定制：添加请求头

Request.Builder requestBuilder = original.newBuilder()

.header("APIKEY", Constant.API_KEY);

//请求体定制：统一添加token参数

if(original.body() instanceof FormBody){

FormBody.Builder newFormBody = new FormBody.Builder();

FormBody oidFormBody = (FormBody) original.body();

for (int i = 0;i

newFormBody.addEncoded(oidFormBody.encodedName(i),oidFormBody.encodedValue(i));

}

newFormBody.add("token",Constant.API_TOKEN);

requestBuilder.method(original.method(),newFormBody.build());

}

Request request = requestBuilder.build();

return chain.proceed(request);

}

});
