Question

我有一个发布请求，我在该请求中发送了一个正文，我在邮递员上尝试了它，效果很好，如发布的图片所示，我从邮递员那里获取了代码，如下图所示，并将其粘贴到我的xcode项目中，下面是完整代码：

 NSDictionary *headers = @{ @"content-type": @"multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW",
                               @"x-session": @"48afbfc4c633983555caa8a816a00e966fb22863",
                               @"cache-control": @"no-cache",
                               @"postman-token": @"5a2ba3be-42e0-95e3-2866-29f8ce83c32a" };
    NSArray *parameters = @[ @{ @"name": @"contacts[0][company_name]", @"value": @"Ali" },
                             @{ @"name": @"contacts[0][type_id]", @"value": @"5" },
                             @{ @"name": @"contacts[0][contact_fname]", @"value": @"jaber" },
                             @{ @"name": @"contacts[0][contact_lname]", @"value": @"jaber2" },
                             @{ @"name": @"contacts[0][contact_phone]", @"value": @"70034491" },
                             @{ @"name": @"contacts[0][remark]", @"value": @"sdsdd" },
                             @{ @"name": @"contacts[0][images][0]", @"value": @"https://otrackapi.omegasoftware.ca/ActStaff/public/uploads/user-image-94.jpg" },
                             @{ @"name": @"contacts[0][lat]", @"value": @"33.311" },
                             @{ @"name": @"contacts[0][lng]", @"value": @"33.234" },
                             @{ @"name": @"contacts[0][contact_email]", @"value": @"me@me.com" } ];
    NSString *boundary = @"----WebKitFormBoundary7MA4YWxkTrZu0gW";

    NSError *error;
    NSMutableString *body = [NSMutableString string];
    for (NSDictionary *param in parameters) {
        [body appendFormat:@"--%@\r\n", boundary];
        if (param[@"fileName"]) {
            [body appendFormat:@"Content-Disposition:form-data; name=\"%@\"; filename=\"%@\"\r\n", param[@"name"], param[@"fileName"]];
            [body appendFormat:@"Content-Type: %@\r\n\r\n", param[@"contentType"]];
            [body appendFormat:@"%@", [NSString stringWithContentsOfFile:param[@"fileName"] encoding:NSUTF8StringEncoding error:&error]];
            if (error) {
                NSLog(@"%@", error);
            }
        } else {
            [body appendFormat:@"Content-Disposition:form-data; name=\"%@\"\r\n\r\n", param[@"name"]];
            [body appendFormat:@"%@", param[@"value"]];
        }
    }
    [body appendFormat:@"\r\n--%@--\r\n", boundary];
    NSData *postData = [body dataUsingEncoding:NSUTF8StringEncoding];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https:xxxxxxxxxxxxxxxx"]
                                                           cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                       timeoutInterval:10.0];
    [request setHTTPMethod:@"POST"];
    [request setAllHTTPHeaderFields:headers];
    [request setHTTPBody:postData];

    NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
                                                completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
                                                    if (error) {
                                                        NSLog(@"%@", error);
                                                    } else {
                                                        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
                                                        NSLog(@"%@", httpResponse);
                                                    }
                                                }];
    [dataTask resume];

响应返回以下错误：

response =     {
        exception = GeneralException;
        message = "Undefined index: type_id";
    };

在我询问后端人员之后，此错误意味着不包括type_id。但实际上它是包含在内的，我没有更改邮递员提供的代码。任何人都可以知道发生了什么事吗？

谢谢

我认为此错误是因为您在字典中像字符串一样传递5，在数字中像@(5)一样传递它。
