Question

我正在为Android开发一个客户端应用程序，我的API要求我在def upload(instances, u1): for instance in instance: try: u1.recv() #do_something except: #do_something_else continue def stop(instances, s1): for instance in instances: RunningStatus = instance[4] if RunningStatus.lower() == 'stopped'.lower(): s1.send(Exception) # I want to raise exception in upload function # from here if __name__ == '__main__': s1, u1 = multiprocessing.Pipe() s = multiprocessing.Process(target = stop, args = (instances, s1,)) u = multiprocessing.Process(target = upload, args = (instances, u1)) s.start() u.start() u.join()中发送图片名称，如：

ArrayList<String>

但是当我发送它时，它的形式如下：

collection[0] = 15a877ce9f22bc8349cac80565c4bff6.jpg
collection[1] = 25a877ce9f22bc8349cac80565c4bff6.jpg

我的改造界面：

collection[] = 15a877ce9f22bc8349cac80565c4bff6.jpg
collection[] = 25a877ce9f22bc8349cac80565c4bff6.jpg

如何达到要求的结果？

任何帮助将不胜感激！谢谢！

Answer 1

不要将[]放在@Field名称中，我不确切知道你为什么要这样做，但这可能会令人困惑，因为那些是保留字符... < / p>

您可以使用以下内容：

// ApiService.java
@FormUrlEncoded
@POST("/api/projectLost")
public void projectMarkLost(
    @Field("apiKey") String apiKey,
    @Field("project_id") int projectId,
    @Field("lost_project_remark") String lostProjectRemark,
    @Field("lost_project_reasons") ArrayList<Integer> lostProjectReasons,
    Callback<JsonObject> cb
);

// Content wish to post
POST content:
apiKey = EzAvFvScs45a2DRI0MktdIDeVRbP59
project_id = 986
remark = testing
details = [detail_1,detail_2]

Answer 2

我找到了使用Map来获得理想结果的解决方案

@FormUrlEncoded
@POST("user/news")
Call<CreateNews> createNews(
        @Field("text") String text,
        @FieldMap Map<String, String> collection);

并在方法中：

public void createNews(String text, ArrayList<String> collection, final Callback<CreateNews> callback){
    News createNews = ServiceGenerator.createService(News.class);

    SortedMap fields = new TreeMap<String, String>();

    for (int i = collection.size()-1 ; i >= 0 ; i--) {
        fields.put("collection["+i+"]", collection.get(i));
    }

    Call<CreateNews> call = createNews.createNews(text, fields);
    call.enqueue(callback);
