ios - 来自 ios sdk 的 HTTP Post

Question

我将不得不在 iOS sdk 中进行 HTTP post 调用，

curl https://www.googleapis.com/urlshortener/v1/url \ -H 'Content-Type: application/json' \ -d '{"longUrl": "http://www.google.com/"} '

对此有什么帮助吗？

很多答案可以在这里和通过谷歌获得。但是，这是一个代码示例。如果您需要更多信息，请进行更深入的搜索。

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:POST_TARGET_URL] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30.0];
[theRequest setHTTPMethod:@"POST"]; // set the method to post
[theRequest addValue:[NSString stringWithFormat:@"multipart/form-data; boundary=%@",QUERY_VALUE_BOUNDRY] forHTTPHeaderField: @"Content-Type"];

NSMutableData *queryData = [[NSMutableData alloc] init];
for (NSString *key in [queryDict allKeys]) { // iterate the keys in an NSDictionary to build the post data with key/value pairs
    [queryData appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\n\n", key] dataUsingEncoding:NSUTF8StringEncoding]];
    [queryData appendData:[[NSString stringWithFormat:@"%@", [queryDict objectForKey:key]] dataUsingEncoding:NSUTF8StringEncoding]];
    [queryData appendData:[[NSString stringWithFormat:@"\n--%@\n", QUERY_VALUE_BOUNDRY] dataUsingEncoding:NSUTF8StringEncoding]]; // begin bounds
}

[theRequest setHTTPBody:queryData]; // set the data object to the body of the post request

_URLConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; // open an NSURLConnection with the request that was just constructed.
