Question

来自(application/json) API邮递员的预期原始数据POST如下：

{"survey_answer":{"answers_json": "{\"4090442c-90ce-42c2-aae8-7c812b7c0f04\":\"test from postman\"}"}}

如何概括要发送给API请求的参数？它是字典吗？如果是这样我如何初始化它？4090442c-90ce-42c2-aae8-7c812b7c0f04是调查ID，取决于正在回答的问题和＆＃34;测试邮递员＆＃34;是通过textfield输入的答案。

谢谢！ @Larme我正在调查AnsAnswerForCurrentSurvey作为字符串我更新了以下代码来更新密钥＆＃34; f884a7d1-f9d9-4563-bb6e-94538664f3bd＆＃34; ： -

NSData *data = [surveyAnswerForCurrentSurvey dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *answerJson = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSMutableDictionary *answer = [answerJson mutableCopy];
if([answer valueForKey:question.name] != nil){
    [answer setObject:textField.text forKey:question.name];
}
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:[answer copy] options:0 error:nil];
NSLog(@"ns data is %@",jsonData);
NSString *json = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(@"json string:%@", json);
NSDictionary *answersDict = @{@"answers_json":json};
NSData *answersAsData = [NSJSONSerialization dataWithJSONObject: answersDict options:0 error:nil];
NSString *answersJSONStringify = [[NSString alloc] initWithData: answersAsData encoding:NSUTF8StringEncoding];
parameters = @{@"survey_answer":answersJSONStringify};

但它给我的结果是 { ＆＃34; survey_answer＆＃34; =＆＃34; {\＆＃34; answers_json \＆＃34;：\＆＃34; {\\＆＃34; 7d2c591c-9056-405c-9509-03266842b7e5 \\＆＃34;：[\\ && ＃34; 1 \\＆＃34]，\\＆＃34; 54bdcf13-e500-418a-8bab-d0639e7e1e28 \\＆＃34;：\\＆＃34; 2 \\＆＃34;，\\ ＆＃34; 63bb0722-7099-4820-a400-36b8938c6ae8 \\＆＃34;：\\＆＃34;你好\\＆＃34;，\\＆＃34; f884a7d1-f9d9-4563-bb6e-94538664f3bd \ \＆＃34;：\\＆＃34;测试来自cms \\＆＃34;，\\＆＃34; ed3acc20-4ae4-493e-ac55-4d2d0f282886 \\＆＃34;：\\＆＃34; 1 \\＆＃34;} \＆＃34;}＆＃34 ;; }

所以我得到＆＃39; \\＆＃39;因此，在最终结果中，请求参数的格式不正确。如何避免它们？

参数问题的JSON映射与＆＃39; \＆＃39;
