【中文标题】我想用 URL POST 方法在字典参数中传递数组

【英文标题】：I want to pass the array inside the dictionary parameter with URL POST method

【问题描述】：

我是 json 新手，我想将 NSDictionary 中的 NSArray 作为参数与 url 一起传递给服务器，当方法是 post 时如何完成？我尝试了示例代码，但没有找到我的确切解决方案。下面是我的示例代码

     NSDictionary *dict = [[NSDictionary alloc]   initWithObjectsAndKeys:@"contact_name", @"kumar",@"designantion",@"sales", nil];
    NSDictionary *finalDict = [[NSDictionary alloc] initWithObjectsAndKeys:dict, @"OfficeContactPerson", nil];



    NSString *post =[[NSString alloc]initWithFormat:@"name=%@&short_name=%@&shop_no=%@&door_no=%@&floor=%@&building=%@&street=%@&area=%@&main=%@&city=%@&state=%@&district=%@&pincode=%@&telephone=%@&contact_name=%@&designatio=%@&mobile=%@&email=%@&OfficeContactPerson=%@",self.txtshowroom.text,self.txtshortname.text,self.txtshop.text,self.txtdoor.text,self.txtfloor.text,self.txtbuilding.text,self.txtstreet.text,self.txtarea.text,self.txtmain.text,cityineger,stateintegervalue,districtintegervalue,self.txtpincode.text,self.txttel.text,self.txtname.text,self.txtdesign.text,self.txtmbl.text,self.txtemail.text,finalDict];

    NSLog(@"postdata :%@",post);


    NSURL *url=[NSURL URLWithString:@"http://139.59.252.34:1337/office"];
    NSData *postData=[post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    NSString *postlength=[NSString stringWithFormat:@"%lu",(unsigned long)[postData length]];
    NSMutableURLRequest *request= [[NSMutableURLRequest alloc]init];

    [request setURL:url];
    [request setHTTPMethod:@"POST"];
    [request setValue:postlength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSError *error=[[NSError alloc]init];
    NSHTTPURLResponse *response=nil;
    NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];


if (!urlData)


    UIAlertView *alert =[[UIAlertView alloc]initWithTitle:@"Error"message:FS_ERROR_LOCALIZED_DESCRIPTION(error.code)
                                                   delegate:nil
                                          cancelButtonTitle:@"OK" 
                                          otherButtonTitles:nil];
    [alert show];


else

    NSString *responseData=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
    NSLog(@"Response data ----->%@",responseData);
    NSError *error=nil;
    NSDictionary *jsonData=[NSJSONSerialization JSONObjectWithData:urlData options:NSJSONReadingMutableContainers error:&error];

);




 OfficeContactPerson": [
  
    "office": 29,
    "contact_name": "Priya",
    "designation": "Prop",
    "department": "ALL",
    "mobile": "1231231231",
    "email": "[e-mail]",
    "incharge_status": null,
    "created_by": null,
    "modified_by": null,
    "id": 14,
    "createdAt": "2016-04-19T13:43:59.000Z",

【问题讨论】：

将数组转换为 Json 字符串并通过服务器发送该字符串值

【参考方案1】：

将数组转换为json 字符串或制作发布数据字典，而不是将其转换为json 字符串并将字符串发布到服务器。我希望下面的代码对你有用。这段代码对我来说很好用-

NSDictionary *dict = [[NSDictionary alloc]   initWithObjectsAndKeys:@"contact_name", @"kumar",@"designantion",@"sales", nil];
NSDictionary *finalDict = [[NSDictionary alloc] initWithObjectsAndKeys:dict, @"OfficeContactPerson", nil];

NSURL *url=[NSURL URLWithString:@"http://139.59.252.34:1337/office"];
NSData *postData=[[[NSString alloc]initWithData:[NSJSONSerialization dataWithJSONObject:finalDict options:NSJSONWritingPrettyPrinted error:nil] encoding:NSUTF8StringEncoding] dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postlength=[NSString stringWithFormat:@"%lu",(unsigned long)[postData length]];
NSMutableURLRequest *request= [[NSMutableURLRequest alloc]init];

[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postlength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

NSError *error=[[NSError alloc]init];
NSHTTPURLResponse *response=nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];


if (!urlData)


    UIAlertView *alert =[[UIAlertView alloc]initWithTitle:@"Error"message:[NSString stringWithFormat:@"%ld",(long)(error.code)]
                                                 delegate:nil
                                        cancelButtonTitle:@"OK"
                                        otherButtonTitles:nil];
    [alert show];


else

    NSString *responseData=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
    NSLog(@"Response data ----->%@",responseData);
    NSError *error=nil;
    NSDictionary *jsonData=[NSJSONSerialization JSONObjectWithData:urlData options:NSJSONReadingMutableContainers error:&error];

hw cn 我通过了上述数据

这是字典还是数组？

字典内的数组

您上面的“发布”字符串不是您发布到服务器的正确 json 格式。就像在第一行代码中所做的那样，使用字典为每个数据创建一个键/值对。

【参考方案2】：

我是 ios 应用程序开发的新手，但我尝试解决。让我们假设这些是你的字符串。试试这个代码：

    NSString *messages-getModuleMessages=@"messages-getModuleMessages";
NSString * authtincateToken=@"WWc3ZFZCcEtWcGxLTk1hZHhEb2hMelFNZzdGcXgwdTBxeU51NWFwUE44TnkrcnF5SCtSMDxxxxxxx";
NSString *accessSecretkey =@"WWc3ZFZCcEtWcGxLTk1hZHhEb2hMelFNZzdGcXgwdTBxeU51NWFwUE44TnkrcnF5SCtxxxxxxxx";
NSString *inboxvalue =@"hai thios is textmessage";

// this is your dictionary value are you passed
NSDictionary * callDict = [NSDictionary dictionaryWithObjectsAndKeys:messages-getModuleMessages,@"call",authtincateToken,@"authToken", accessSecretkey, @"accessSecret",inboxvalue,@"calotype",@"json",@"format",nil];

  // convert your dictionary to NSData
  NSData *jsonData = [NSJSONSerialization dataWithJSONObject:callDict options:kNilOptions error:nil];
 // this is your service request url
  NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://xxxxxxxx"]];
 // set the content as format
 [request setHTTPMethod:@"POST"];
[request setHTTPBody: jsonData];
  // this is your response type        
 [request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"content-type"];
   NSError *err;
  NSURLResponse *response;
   // send the synchronous connection
   NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
   // here add your server response NSJSONSerialization
  NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err]; 

  // if u want to check the data in console
  NSString *tmp=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
    NSLog(@"%@", tmp);

【参考方案3】：

尝试下面的代码行并将它们放在前两行代码的位置。问题只是在那里。

    NSDictionary *dict = [[NSDictionary alloc]   initWithObjectsAndKeys:@"contact_name", @"kumar",@"designantion",@"sales", nil];
    NSDictionary *finalDict = [[NSDictionary alloc] initWithObjectsAndKeys:[NSArray arrayWithObject:dict], @"OfficeContactPerson", nil];
NSData *POST_Params = [NSJSONSerialization dataWithJSONObject:urlParams options:NSJSONWritingPrettyPrinted error:nil]; // Pass these post data in request

希望这对你有用！！

而且我还有一些文本字段，例如名称商店名称，例如 dat

br0 officecontactpersn 是键，然后是数组

在 JSON 中 [] 表示数组， 表示字典。你按照我的回答试过了吗？
