MusixMatch API响应返回200，但没有值返回JSON

Question

我正在使用musixMatch api获取给定的曲目列表，并给定一个MusixMatch分配的相册ID。我使用的专辑ID是20903197，我已经验证了它的工作。https://playground.musixmatch.com/#！/track/get_album_tracks_get将其插入专辑_ID字段

但是，当我尝试使用他们的python sdk调用它时，我会得到所有属性的响应，但返回200响应。我在他们的网站上的Swagger上对其进行了测试，而且效果很好。他们的API是否有可能破坏或我做错了什么？

这是我当前的脚本：

import time
import swagger_client
from swagger_client.rest import ApiException
from pprint import pprint

swagger_client.configuration.api_key['apikey'] = 'API_KEY_HERE'

api_instance = swagger_client.TrackApi()
album_id = '20903197' # str | The musiXmatch album id
format = 'json' # str | output format: json, jsonp, xml. (optional) (default to json)
callback = 'callback_example' # str | jsonp callback (optional)
f_has_lyrics = 'f_has_lyrics_example' # str | When set, filter only contents with lyrics (optional)
page = 3.4 # float | Define the page number for paginated results (optional)
page_size = 3.4 # float | Define the page size for paginated results.Range is 1 to 100. (optional)
try:
    api_response = api_instance.album_tracks_get_get(album_id, format=format, callback=callback, f_has_lyrics=f_has_lyrics, page=page, page_size=page_size)
    pprint(api_response)
except ApiException as e:
    print "Exception when calling TrackApi->album_tracks_get_get: %sn" % e

我得到了此回应：

Answer 1

要找到此问题需要查看Swagger-client 由Swagger Editor生成的代码的原因：对于 api_client的同步回顾。py-> __call_api ，默认情况下，从服务返回的结果将导致空有效负载。

要修复它需要通过设置参数 _PRELOAD_CONTENT = false 。

复制步骤：

1. swagger.json github上的musixmatch-service

2. 使用Swagger编辑器以Swagger.json

生成Python-Client

3. 安装自动化模块 Swagger-client

4. 运行代码

import swagger_client
from swagger_client.rest import ApiException
import json

configuration = swagger_client.Configuration()
configuration.api_key['apikey'] = '..'
api_instance = swagger_client.TrackApi(swagger_client.ApiClient(configuration))
album_id = 20903197
try:
    api_response = api_instance.album_tracks_get_get(album_id, _preload_content=False)
    result = json.loads(api_response.data)
    print(result)
except ApiException as e:
    print("Exception when calling TrackApi->album_tracks_get_get: %sn" % e)
