我想从我的iOS应用程序向网络服务发送POST请求。到目前为止，我已经发送了一个JSON对象，它正在工作。现在我想将数据作为参数发送。我做了类似的事。
my_list = [2, 1, 3]
# .sort() is a list method that applies the sorting logic to a
# specific instance of list, in this case, my_list
my_list.sort()
# sorted is a built-in function that's more generic which can be
# used on any iterable of Python, including list type
sorted(my_list)
这是我的[request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[NSData dataWithBytes:[postParam UTF8String] length:[postParam length]]];
NSError *error = nil;
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error: &error];
NSString *string = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
字符串
postParam这是我的action=approve&requestId=0&reqDetailId=21&nextApproverCode=0&authIpAddress=122.127.0.114&remarks=Test&approval=C
request但我收到了错误消息
<NSMutableURLRequest: 0x151323e60> { URL: http://<url>/Workflows/WorkflowApprovals? }
这是什么原因？

由于它是POST方法，您无法发送查询字符串
创建一个字典并传递其中的所有参数
