问题描述

我想通过json webservicesmy发布数据按钮点击操作代码是：

I want to post data through json webservicesmy on button click Action code is:

-(IBAction)login:(id)sender {
    NSString *newurlString = [NSString StringWithFormat:@"{\"name\":\"asit\",\"email\":\"[e-mail]\",\"businessType\":\"1\",\"score\":30}"];
    NSString * url = @"http://www.nieuwe-dag.nl/mobile_be/public/?action=saveScore";

    NSData *postData = [newurlString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
    NSLog(@"urlString::%@",newurlString);
    NSLog(@"postLength::%@",postLength);

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:300];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSURLConnection *theConnection =[[NSURLConnection alloc] initWithRequest:request delegate:self];


    if( theConnection ) {
        webData = [[NSMutableData data] retain];
    }
    else {
        NSLog(@"theConnection is NULL");
    }
}

并且控制台上的响应是：

推荐答案

您的 newurlString 必须包含变量名称。如果你也添加百分比，那也没关系。例如：

Your newurlString must contain the variable name. It will be OK if you add percentage engoding too. For example:

NSString *newUrlString = [[NSString stringWithFormat:@"&json={\"name\":\"asit\",\"email\":\"[e-mail]\",\"businessType\":\"1\",\"score\":30}"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

如果您没有看到任何更改，请点击此处：

If you don't see any changes, here they are:

1. 在字符串的开头是& json = 。将其更改为您的真实变量名称。例如。如果您的服务器在 $ _ POST ['data'] 中检查json，则应使用& data = 。


2. 有 stringByAddingPercentEscapesUsingEncoding ，它增加了百分比转义（例如空格转换为％20 ）

1. Thre is &json= at the begining of the string. Change it to your real variable name. E.g. if your server checks for json in $_POST['data'], you should use &data=.
2. There is stringByAddingPercentEscapesUsingEncoding which adds percent escapes (e.g space is converted to %20)

编辑：对不起，这是正确的代码：

Sorry, here is the proper code:

NSString *newUrlString = [NSString stringWithFormat:@"&json=%@",[[NSString stringWithFormat:@"{\"name\":\"asit\",\"email\":\"[e-mail]\",\"businessType\":\"1\",\"score\":30}"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
